24 Chapter 1 Ethernet Port Connector Figure 10 shows the Ethernet network connector on the rear panel. This is an 8-way US Modular connector and is used to connect the IPR device to the network. Figure 10. Ethernet network connector Pin 10/100Base-T Signal 1 Transmit+ 2 Transmit- 3 Receive+ 4 Unused 5 Unused 6 Receive- 7 Unused 8 Unused Radio Port Connector The radio port provides an 8-way US Modular connector for 4-wire audio with E&M signaling. This port is balanced with 600-ohm transformer coupling. This provides isolation between the port and the radio and virtually eliminates any ground noise and induced signals. The E&M design can be configured for relay control or opto (voltage) input/output. Hardware links on the rear panel allow the interface control signals to be configured to source or sink power. The 4-Wire E&M Radio port is used to connect to a radio. This connector provides input and output audio and E&M control signals that may be configured by the adjacent links, as shown in Figure 11. The link settings for the E&M control signals are described in E&M Configuration on page 14. Figure 11.

25 Advanced Functionality The IPR device includes sophisticated technology to efficiently transport audio over an IP network such as the Internet or your organization s local network. Session Initiation Protocol (SIP) The IPR100 and IPR110Plus use the Session Initiation Protocol (SIP) to dynamically connect and disconnect VoIP connections. This allows the IPR device to be used with Omnitronics dispatch and diagnostic software, which can remotely connect to an IPR device to monitor or transmit audio on demand. SIP Interoperability The IPR110Plus provides a complete SIP implementation that allows the IPR110Plus to interact with other devices that support SIP. Third party devices that support SIP include: Software based SIP phone (soft phones) allowing connection from a PC to an IPR device SIP Telephone Systems allowing access to the radio from a phone system SIP to PSTN Service Provider allowing access to the radio from any PSTN telephone Bandwidth Optimization The input audio is digitized and then compressed using a digital signal processor with one of several possible codec schemes. The compressed audio is then transported over IP The digital signal processor also provides Voice Activity Detection (VAD) and silence suppression. Together, these features enable the IPR products to make optimal use of the available IP bandwidth. With VAD and silence suppression audio packets are generated only whilst a person is actually talking. As soon as silence is detected, the transmission of data packets is suspended. VAD is also useful when connecting to communications equipment that does not provide a COS or Busy (Mute) output. It performs a VOX function, activating COS outputs while voice is present. IPR100/IPR110Plus Product Manual 9

26 Chapter 1 Speed Dial The IPR110Plus can be configured with up to twelve speed-dial entries that can call any SIP address. Each speed-dial entry can be any SIP address, which could be another IPR device, a Windows computer running SIP software, or a telephone (via a SIP phone system). The speed-dial entries can be called from a radio by sending a configured DTMF or SELCALL sequence. Remote Configuration The IPR100 and IPR110Plus can be configured within the LAN, WAN, or Internet environment, using a web browser. Two configuration modes ae provided: Basic Mode, which provides access to the essential settings required to get two IPR products communicating, and Advanced Mode, which provides access to all product features. Tone Signaling The IPR device has been specifically designed to transport signaling schemes such as SELCALL, DTMF, and CTCSS over data networks. Analog signaling schemes will not work reliably through a data network when audio compression below 64kbps is used. Compression algorithms degrade audio tones resulting in poor signal decoding at the end stations. The IPR products overcome this problem by directly decoding analog signaling tones at the source and encoding them into data messages. Similarly, the reverse operation (analog encoding) is performed at the transmission end. Encryption Another major feature of both the IPR100 and IPR110Plus is the built-in security. The IPR100 and IPR110Plus support DES and AES 128-bit (Australia models only) encryption which can be enabled for all voice and data transmissions. In addition the IPR110Plus (Australia models only) provides AES-256-bit encryption for extra security. Firmware Upgrades The firmware in the IPR device is stored in Flash memory so it can be upgraded with a new version of the firmware when it becomes available. Omnitronics periodically provides upgrades to the firmware to resolve issues or to provide enhancements and additional functionality. For further information on upgrading the firmware, see Upgrading the Firmware on page Introducing the IPR

27 Chapter 2 Getting Started This chapter discusses the hardware requirements and includes the following: Hardware Setup Connecting to the Network on page 19 Resetting to Factory Default Settings on page 26 Hardware Setup The hardware has undergone several improvements and revisions: prerevision 3 and revision 3 and later. The following information will help you determine the revision of your hardware without opening the enclosure. Identifying the Hardware Revision Using the web-based configuration interface, you can view the hardware revision information on the System Status configuration page (see Viewing the System Status on page 41). The back panel is different for the different hardware revisions. Figure 12 shows the back panel for pre-revision 3 and Figure 13 shows the newer back panel for revision 3 and later. Figure 12. Rear panel of IPR device (pre-revision 3) Figure 13. Rear panel of IPR device (revision 3 and later) IPR100/IPR110Plus Product Manual 11

28 Chapter 2 Differences between Hardware Revisions IPR devices with hardware prior to revision 3.00 provide internal links that configure various options such as an audio compressor to limit the input audio level and emphasis/de-emphasis to improve the quality of the audio. Table 3 lists the various links (default settings are shown in bold type). Table 3. Internal links on the PC board Link Position Description LK1 Out Reserved LK2 Out Reserved LK3 In Supply 1.5V to debug interface Out Disconnect 1.5V from debug interface LK4 1-2 Flat audio response applied to input - used with link LK7 2-3 De-emphasis applied to input - used with link LK7 LK5 1-2 Flat audio response applied to output - used with link LK6 2-3 Pre-emphasis applied to output- used with link LK6 LK6 1-2 Flat audio response applied to output - used with link LK5 2-3 Pre-emphasis applied to output- used with link LK5 LK7 1-2 Flat audio response applied to input - used with link LK4 2-3 De-emphasis applied to input - used with link LK4 LK8 For details, see section E&M Configuration on page 14 LK9 1-2 Compressor used with input audio 2-3 No compressor used with input audio The various types of links are labeled as shown in Figure 14. Pin 1 of header links and solder links is printed on the PCB and is located adjacent to the square pad (header links) or semicircle-shaped pad (solder links). E&M links are labeled accordingly on the back panel Figure 14. Header links, solder links, and E&M links Figure 15 on the following page shows the function of the internal links in the audio path. 12 Getting Started

29 Figure 15. Link functions in the audio path (pre-revision 3 hardware) IPR devices with revision 3.00 or later hardware do not require the audio compressor circuit or the emphasis/de-emphasis circuitry. Hence, the later revisions do not provide link settings for the above; and therefore, you do not need to open the enclosure to set up the unit. The later revisions provide an additional jumper for the 600-ohm termination on the input to the radio port. This jumper is located on the left-hand side of the 4-Wire E&M Radio port and is identified by the T label (see Figure 10 and Figure 12). When the T jumper is removed, the 600-ohm terminating resistor is out of circuit and the input becomes a high-impedance input greater than 10kΩ. Revision 3.00 of the hardware requires at least revision 5.00 of the firmware. Attempting to download an earlier revision of firmware will result in an error message.

E&M Configuration The following sections discuss how the E&M control signals can be interfaced to various types of radio equipment using relay contacts and typical circuitry. The E&M signals are configured by the links on the back panel. Links A and B configure the BUSY (E) input and links C and D configure the PTT (M) output. If you are using hardware version 3 or later, another E&M option is available called the termination ( T ) link. This link connects or disconnects a resistive load across the receive pins of the 4-wire E&M radio port allowing the IPR device to accept either a 600-ohm balanced or unbalanced audio source depending on your radio device. The T-link settings are listed in Table 5. Table 5.

35 Connecting to the Network Omnitronics offers a system configuration service at the customer s request to configure the IPR device and other DX-Altus system components. If your device is preconfigured for your network, you can simply connect it to your network and start using it as is. You can skip ahead to the next chapter, Chapter 3, Basic Configuration, which explains how to use the configuration interface in case you want to make some changes to the configuration. When preconfigured, the product documentation supplied with the system will describe all of the static IP addresses used in the system including that of any IPR devices. However, if your device is not preconfigured, you will need to initially configure the basic network settings so that it can communicate on your network. The easiest way to configure the IPR device is to connect it directly to your computer s Ethernet port using a network cable. The IPR device is factory configured (see Table 16 on page 170) with a static IP address as follows: for devices with an even-numbered serial number for devices with an odd-numbered serial number If the IPv4 address of your computer does not have a similar address (i.e., an IP address starting with x), it will not be able to communicate with the device. In this case, you will need to change the IPv4 address of your computer temporarily to the same subnet as the IPR device. Once your computer and the IPR device are both on the same network, you can then login to the device s configuration interface to configure the network settings of the device to match your network. You can then restore the network settings of your computer. Using the Serial Monitor to Configure the Basic Network Settings If you do not know the IP address of your IPR device, you can use the Serial Monitor to configure the basic network settings such as the IPv4 address, subnet mask, and gateway address to match your computer network. Once you have configured the basic network settings, you can then log in to the device and use the built-in web server to configure the other settings. Using the Serial Monitor method is not recommended for non-technical users as it is primarily intended for diagnosing and resolving issues by system administrators and support engineers. For further information about using the Serial Monitor, refer to Using the Serial Monitor on page 168.) IPR100/IPR110Plus Product Manual 19

43 Chapter 3 Basic Configuration This chapter describes the basic configuration of the IPR device and includes the following sections: What is the Configuration Interface? Launching the Configuration Interface on page 28 Network Discovery on page 28 Using the Configuration Interface on page 29 Viewing the System Status on page 41 Configuring the Basic Network Settings on page 43 Changing the Supervisor Password on page 45 Backing up and Restoring the Configuration on page 46 Radio/Handset Settings on page 51 VoIP/RTP Configuration on page 53 What is the Configuration Interface? The IPR100 and IPR110Plus products include a built-in configuration interface you can access using your web browser. The configuration interface provides password-protected access and should be compatible with most modern web browsers. The configuration interface consists of a series of web pages designed to help you configure and manage the operation of the IPR device. You can access all the status information, configuration settings, and diagnostic tools in one convenient user interface. The web pages use JavaScript so you should ensure that JavaScript is enabled your web browser. The configuration interface supports the following web browsers: IPR100/IPR110Plus Product Manual 27

44 Chapter 3 Internet Explorer 9 11 Firefox 38 or later Google Chrome 14 or later Safari 5 or later It may also be compatible with other web browsers not listed above; however, Omnitronics cannot guarantee the compatibility of such browsers. Launching the Configuration Interface To launch the configuration interface, you must be able to navigate to the IPR device on the network using your web browser. Hence, you need to know the IP address of the IPR device. If you are configuring the IPR device with factory default settings, you can use the default IP address ( or If you do not know the IPv4 address of your IPR device, you might be able to use the Network Discovery feature of Windows to discover the IPR device on your network, as described in next section. Network Discovery If the IPR device and your computer are connected to the network, and UPnP (universal plug-n-play) is enabled in the IPR device, you should be able to discover it on your network. You will see all of the computers and devices that are currently part of the network in the Network folder as shown in Figure 20. Figure 20. Discovering the IPR device with WIndows 7 28 Basic Configuration

45 The IPR device product should appear with a VoIP Device name (e.g. VoIP Device IPR100: Version or VoIP Device IPR110PLUS: Version ) Once you have located the IPR device, double-click on it to automatically load the log-in page in your web browser. Note To discover the IPR device on your network, the network settings of the must match those of the computer used to access the devices. That is, the IP address of the IPR device must be on the same subnet as the IP address of the computer. Using the Configuration Interface All configuration and management of the IPR device is done using the built-in web server, known as the configuration interface. You must login to the configuration interface with a user name and a password before you can view or change any of the configuration settings. To login, you must be able to navigate to the IPR device on the network using your web browser, and you need to know the IP address of the device. If you are configuring an IPR device with factory default settings, you can use the default IP address of or You might be able to use the Network Discovery feature of Windows to discover the IPR device on your network (see Network Discovery on page 28). The following sections discuss how to login and use the configuration interface to configure the IPR device. Layout of the Configuration Interface Figure 21 shows the basic user interface of the Configuration Interface when logged in under the supervisor account the page shown here is the Network Configuration page (see Configuring the Basic Network Settings on page 43) that is displayed when you select the Network menu in Basic Mode for the IPR110Plus (the corresponding page for the IPR100 looks similar to this one). At the bottom of this page is the Configuration Status area, which shows the status of the configuration and whether you have made any changes to the settings. This area appears on all pages that have configuration settings that you can change, and displays various status messages (see Configuration Status on page 36). IPR100/IPR110Plus Product Manual 29

46 Chapter 3 Configuration page Displays the name of the configuration page Basic Settings Displays the basic settings for the configuration page Menu system Basic and Advanced menu modes Configuration status Shows the configuration status and provides buttons to save, undo, and reset the configuration. Figure 21. Using the Configuration Interface user interface The left-hand panel of the configuration interface provides the menu system, which shows a menu item for each of the available configuration pages the items shown in the menu depend on the user account you used when you logged in to the system and which menu mode you are using (the menu modes are discussed below). When you log in, the Basic Menu mode is shown by default. The various configuration pages are accessed by clicking on the menu items located on the left-hand panel of the web interface: selecting a menu item displays the corresponding configuration page on the right-hand panel of the interface. The Configuration Interface has two modes of operation: Basic Mode provides access to basic configuration settings that allow you to configure the IPR device with minimal settings to get it up and running quickly. This mode is most suitable for simple or straight-forward installations in which the basic settings are sufficient. Advanced Mode provides more advanced configuration features supported by the devices. This mode allows you to perform more advanced configuration of the devices for installations in which you need more control over the operation of the devices. The first item in the menu is Go to ADVANCED mode. Clicking on this item changes the configuration interface into Advanced Mode. In advanced mode, additional menu items and configuration pages are available, and the first menu item changes to Go to BASIC mode. Clicking on this item reverts back to basic mode. 30 Basic Configuration

47 When you are done configuring the IPR device, you should always log out of the Configuration Interface by clicking Exit (see Logging Out on page 40). This will take you back to the log-in page and prevent unauthorized access to the configuration pages. You will need to enter the user name and password again to access the configuration pages. User Accounts and Logging In Before you can configure the IPR device, you must first login using one of the built-in user accounts. Depending on the user account you use, you can either access all configuration pages, or just a subset of the pages. The following types of user accounts are provided: Supervisor User Account provides full access and allows supervisors or system administrators to configure all the settings of the IPR device. Technician User Account provides read-only access to the System Status page and several Diagnostics pages. Limited User Account provides access to only the System Status page and the Radio Diagnostics page. To access the login page of the IPR device, you can either use the network discovery feature described in the previous section, or launch your web browser and use the IP address of the IPR device (i.e. either the factory default IP address or the IP address you configured in Connecting to the Network on page 19) to access the configuration pages. For example, if using the default IP address, type or in the address bar of the browser window. The bowser should then display the login page. Figure 22 shows the log-in page for the IPR110Plus and Figure 23 shows the log-in page for the IPR100. Figure 22. IPR110Plus log-in page Figure 23. IPR100 log-in page When you click the Log In link, the password dialog similar to the one shown Figure 24 appears when using Microsoft Windows Internet Explorer 9. IPR100/IPR110Plus Product Manual 31

48 Chapter 3 Figure 24. Logging in using Windows 7 When you configure the IPR device for the first time, you must log in under the built-in supervisor account by using the default user name of omni (case insensitive): this user name cannot be changed and is the same for both the IPR100 and IPR110Plus. The password you type, however, depends on which device you are configuring, as shown in Table 6. Table 6. Default user names and passwords for supervisor account Device Model User name Password IPR100 omni ipr100 IPR110Plus omni ipr110+ Note The password is case sensitive and must be typed in lowercase characters make sure the Caps Lock key is not active on your computer keyboard. Once you have logged in, you will see the System Status page the appearance of this page depends on which device you are configuring and the account you used to login (see Viewing the System Status on page 41). You can also change the password of the supervisor account to prevent unauthorized access (see Changing the Supervisor Password on page 45). The password can contain up to 10 characters in length and may include any character that can be typed using an English language keyboard. 32 Basic Configuration

49 Supervisor User Account When you login under the supervisor account, you will see the System Status page similar to the ones shown in Figure 25 depending on which device you are configuring. This page is the same in both the basic advanced menu modes. As a supervisor, you have unlimited access to the configuration settings and are responsible for configuring the IPR device and setting up the user names and passwords for the technician and limited-user accounts. Whilst you are logged in under the supervisor account, it is recommended that you change the password of the supervisor account so that non-supervisors cannot gain unrestricted access to the IPR device. You should also set up the user name and password for both the technician account and the limited-user account if required. Figure 25. System status page for supervisor account IPR100/IPR110Plus Product Manual 33

50 Chapter 3 Technician User Account When you log in to the Configuration Interface under the Technician account, only a limited set of menus and configuration pages appear similar to the ones shown in Figure 26. Figure 26. IPR110Plus system status page for technician account Under the technician account, you can view the status of the system, such as the System Version Information, the Current Status, and the Channel Information. Additionally, you can also access several of the Diagnostics pages, such as the Diagnostics and Statistics pages. 34 Basic Configuration

51 Limited User Account When you log in to the Configuration Interface under the Limited-User account, only the System Status page appears similar to the ones shown in Figure 27. Figure 27. IPR110Plus system status page for the limited-user account Additionally, limited users can also access the Statistics page under Diagnostics. IPR100/IPR110Plus Product Manual 35

52 Chapter 3 Configuration Status On all configuration pages that provide settings you can change, a configuration status area is displayed along the bottom edge of the page. This shows the status of the configuration settings for the current page, such as whether you have made any changes to the configuration, or the configuration has changed but you have not saved the changes you made. Figure 28 shows the Configuration Status area that is displayed when no changes to the configuration are pending. The one shown here is for the IPR110Plus, however, it is the same for the IPR100. Save button Saves changes to the configuration Restart button Restarts the device Undo button Discards any changes Reset to Defaults button Reloads factory default settings Status message area Shows status messages Figure 28. Configuration status area The Configuration Status area shows the status of the IPR device configuration, and provides several buttons to allow you to save or undo any changes you make to the configuration settings. You can also reset the IPR device to its default factory settings, and restart the IPR device as required. The buttons in the Configuration Status area and the function they perform are described below: Save allows you to save the changes you made to the settings on the configuration page displayed in the web browser. You must always save the configuration before navigating to another configuration page otherwise the changes will be discarded. Restart performs a restart of the IPR device using configuration settings from flash memory a restart is required after you save any the changes to the configuration. Reset to Defaults reloads the configuration with default values for settings on all configuration pages (not just the page displayed in the browser), but does not save the default settings to flash memory. Undo discards any changes that you made to the settings on the configuration page displayed in the web browser, and reloads the configuration. This affects the settings on all configuration pages; not just the settings on the current page. 36 Basic Configuration

53 The Status Message area is immediately above the buttons. Table 7 provides a description of each status message. Table 7. Configuration status messages Status Configuration Unchanged Configuration has been saved. Restart required to take effect. Data is invalid: IT HAS NOT BEEN SAVED Configuration reset to defaults: NOT SAVED Configuration reset to saved values Description Indicates that the configuration settings on the page have not changed. Indicates that the configuration settings have been saved into flash memory of the IPR device, but are not currently used. A restart is required before the new settings will take effect. Indicates that one (or more) of the settings entered was invalid and the configuration has not been saved. All configuration values on a page must be valid before any values will be saved. You must identify all incorrect configuration values and correct the errors. The Configuration Status area will show additional information about the incorrect value. Indicates that the ALL configuration settings have been reset to the default values; not just the settings on this page. However, you still need to save the changes to make the changes permanent. The configuration values on the configuration page have been restored to the values saved in the flash memory. This is the result of clicking the Undo button. Note If you change the configuration setting(s) on a page, you must save the configuration before navigating to another page otherwise any changes you made will be discarded Saving Configuration Settings When you make changes to the settings on a configuration page, or you restore the configuration from a backup file, you must save the changes to the IPR device; otherwise if you navigate to another configuration page, the changes will be discarded. To save the configuration changes, click the Save button on the page. When you save the changes, the message displayed under Configuration Status changes to Configuration has been saved. Restart required to take effect, as shown in Figure 29. This message advises you that the configuration has been permanently saved, however, you now need to restart the IPR device so that the new settings can be loaded (see Restarting the IPR Device below). IPR100/IPR110Plus Product Manual 37

54 Chapter 3 Figure 29. Saving the configuration changes Restarting the IPR Device Once you have made changes to the configuration, or restored the configuration from a backup file, and saved the configuration, you must restart the IPR device for the changes to take effect. To restart the IPR device, click the Restart button on the page. Warning Do not disconnect power to the IPR device while it is restarting otherwise it may cause damage or corrupt the firmware. While the IPR device is restarting, the page will show Restart in Progress, as shown in Figure 30. After about 30 seconds, it should restart and you will be redirected to the login page. You will need to login again if you want to continue configuring the IPR device (see User Accounts and Logging In on page 31). Figure 30. Restarting after saving the configuration settings 38 Basic Configuration

55 After restarting the IPR device, it is recommended that you back up the configuration for safekeeping in case you need to restore it later (see Backing up and Restoring the Configuration on page 46). If you can no longer use your web browser to communicate with the IPR device after restarting it, this is most likely due to the IP address of your computer is now on a different subnet than the IPR device. In this case, you ll need to change it to the same subnet as the IPR device before you can use your web browser. For further information on how to change the IP address of your computer, refer to Connecting to the Network on page 19. Note You may need to refresh your web browser after the IPR device has restarted. Resetting the Configuration to Default Settings Sometimes you may want to reset the configuration of the IPR device to its factory default settings. This is especially useful when you want to change only a handful of settings as it provides a good starting point for configuring the device. In most cases, the default configuration will do for basic installations with only some minor changes. The default configuration is also useful when you need to troubleshoot a particular problem or the device is not operating as you expected. In this case, you can start with the default settings and carefully make changes as required to determine the cause of any problem. Figure 31 shows the three steps involved in resetting the IPR device to factory default settings. The first step is to click Reset to Defaults. This resets the in-memory configuration to defaults but does not make the changes permanent. To make the changes permanent, you need to save the default configuration by clicking Save as per the second step. The final step in resetting to defaults involves restarting the device by clicking Restart. Note, however, that because the IPR device is now reset to the factory-default settings, you may not be able to communicate with it using the same IP address. This is because it has reverted to its default IP address set at the factory. IPR100/IPR110Plus Product Manual 39

56 Chapter 3 Figure 31. Resetting the configuration to default settings In this case, you may need to change the network settings of your computer temporarily in order to use your web browser to communicate with the device (see Connecting to the Network on page 19). Logging Out Once you have completed configuring the IPR device, it is recommended that you log out by clicking the Exit. If you want to continue configuring the IPR device, you will need to type your user name and password to log back in again (see User Accounts and Logging In on page 31). 40 Basic Configuration

Dynamic DNS Status The Dynamic DNS Status section appears only if you enable the dynamic DNS under the advanced network configuration and includes the following: Consecutive No Change Updates shows the Dynamic DNS status with the current public IP Address, previous public IP Address (if available), the number of consecutive No Change updates, and the last dynamic DNS update result (if available). For further information about Dynamic DNS, refer to the relevant section for your device: IPR100, see Dynamic DNS on page 61 IPR110Plus, see Dynamic DNS on page 95. Configuring the Basic Network Settings Select Network to configure basic network parameters such as IP address, network mask, and the gateway address of the IPR device. Figure 33 shows the basic network configuration for the IPR110Plus (the IPR100 is similar). Figure 33. Basic network configuration page IPR100/IPR110Plus Product Manual 43

60 Chapter 3 Basic Network Settings This section allows you to configure the basic network settings of the IPR device and include the following: Location Name is the name assigned to the installation site. It is also the value that will appear in the Windows Network Neighborhood and can also be used to access the device by name on a local network. This setting consists of alphanumeric characters up to a maximum length of 100, but must not contain any spaces or punctuation characters. The default name is the type of device followed by its serial number. For example: IPR100 with a serial number of 52A1212 would have the default name of IPR100-52A1212, and an IPR110Plus with a serial number of 52A0526 would have a default name of IPR110PLUS-52A0526. Automatically obtain IP Address (using DHCP) option is used to allow the IPR device to obtain an IP address automatically from a DHCP server. When DHCP is enabled, the static IP address, network gateway address, and the domain name server settings will be ignored as appropriate values will be provided by the DHCP server. When this option is selected, the other network settings will be disabled. The default setting is disabled. Static IP Address is the IPv4 address of the IPR device, which consists of 32 bits expressed in a form consisting of four decimal octets separated by periods (dots), called dot-decimal notation. The default is or (the default configuration is to use a static IP address). Note If you want to use the option to Automatically obtain an IP Address (using DHCP), the IPR100/110Plus will attempt to locate a DHCP server on start up. If it cannot find a server, it will either use the static IP address or automatically assign itself an address in the range x.x. In this case, the IPR100/110Plus will take a little longer to start up before it times out waiting for a DHCP server. Netmask is the subnet mask that determines what part of the IPv4 address is used to identify the subnet that the IPR device is on. A valid IPv4 subnet mask consists of 32 bits: a sequence of ones (1) followed by a block of zeros (0), expressed in a form consisting of four decimal octets separated by periods (dots), called dot-decimal notation. The sequence of ones (1) designates that part as the network prefix (subnet) and the block of zeros (0) designates that part as the host identifier. The default value is Gateway Address is the IP address of the default network gateway. This would usually be the IP address of the router or network device that provides access to the WAN or internet. A valid IPv4 gateway address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dots), called dot-decimal notation. The default value is Basic Configuration

61 Using a DHCP Server Select Automatically obtain IP Address (using DHCP) to enable Dynamic Host Configuration Protocol (DHCP), which allows the IPR device to obtain an IP address automatically from a DHCP server. When DHCP is enabled (this is the default setting), the static IP address, network mask (netmask), and network gateway address settings will be ignored as appropriate values will be provided by the DHCP server. If you want to assign a static IP address to the IPR device, deselect this option and type the static IP address, subnet mask, and gateway address you want to assign. It is recommended that you allocate an address in the range of to or to as these are especially reserved for private addresses. When using a DHCP server to automatically allocate an IP address to the IPR device, another IP device will not be able to communicate with the IPR device unless multicast addressing or local mdns is used as it will not know the IP address allocated by the DHCP server. Multicast Addressing is a protocol for efficiently sending data to multiple IPR devices at the same time over TCP/IP networks (see Multicast Addressing on page 55 for further details). Local mdns name allows the IPR device to connect to another IPR device by using a local name address instead of an IP address. Local addressing takes the form of <name>.local, where <name> is the Location Name configured on the Network settings page (e.g., IPR device- 52A1680.local). Changing the Supervisor Password Figure 34 shows the Change Password page that is displayed when you select the Change Password menu in Basic Mode. This page allows you to change the supervisor password used to login to the IPR device under the supervisor account. To change the password of the supervisor account, type the new password in the Enter supervisor password textbox, and then retype it in the Confirm password textbox. Make sure you save the new password by clicking Save (see Saving Configuration Settings on page 37), and then restart the IPR device by clicking Restart for the new password to take effect (see Restarting the IPR Device on page 38).

67 Radio/Handset Settings Select Radio to configure settings for the radio peripheral devices you want to use as shown in Figure 36. Figure 36. Basic Radio/Handset configuration page Basic Settings The basic settings that you can configure on this page include the following: Device type is the type of device connected to the IPR device, and can either be an Omnitronics Handset (or Console) or a radio. This setting selects the mode of operation and affects how the control interface operates. The following modes are provided: Radio Handset/Console Radio and Handset/Console: Audio linked The IPR device energizes the radio PTT relay and monitors the radio busy status on the E&M connector on the rear panel. This is the default mode. The IPR device energizes the handset busy output and monitors the handset PTT input. In this mode, all three sources are linked together so that each source drives the other two. This allows the local handset to be used with the local radio as well as the remote equipment. The audio into one port sends audio to both of the other ports. IPR100/IPR110Plus Product Manual 51

68 Chapter 3 The PTT for the radio port and the busy output for the handset port are driven simultaneously. Both the radio busy signal and the handset PTT signal are read and used in processing the audio. On the handset port, the PTT input from the handset is used to drive the signaling to the network and the PTT relay for the radio port. On the radio port, the busy input is used to drive both the signaling to the network and the busy output to the handset. Radio and Handset/Console: Remote Audio only In this mode, both the radio and handset ports are connected to the network port but not to each other. This means that the audio from the network goes to both ports simultaneously but audio from the radio port and the handset port is summed and only goes to the network port. On the handset port, the PTT input from the handset is used only to drive the signaling to the network, and the handset busy is only driven by the network signaling. On the radio port, the busy input is used only to drive the signaling to the network, and the PTT is only controlled from the network signaling. Note The audio circuitry is active regardless of which mode you select: the received network audio will be output on both the radio and handset/console ports. If the firmware detects revision 2 hardware, the functions for Radio and Handset/Console: Audio Linked and Radio and Handset/Console: Remote Audio only are not available; and the Radio/Handset configuration page will provide a check box for the compressor this check box does not appear in rev 3 series hardware as there is no compressor in the hardware. Volume (output level) controls the level adjustment for audio output from the IPR device. The allowed values are: -10 to +10dB. The default setting is 0dB. This controls the audio level from the VoIP link that is output from the IPR device and the input to the radio or handset/console. Setting the value to 0dB applies no gain, and increasing this value makes the output from the IPR louder, while applying a negative value decreases the level below the VoIP level. Allowed Values: -10 to +10dB. Default: Transmit Gain 0dB. 52 Basic Configuration

69 Expected audio input level is the level adjustment of the input to IPR device. Set this to the level of the expected input signal. This value should be set to the nominal level output by the radio or handset/console connected to the IPR device. The IPR device will take the expected audio input level and transmit it across the VoIP network at -10dBm. With the expected audio input level set to -10dBm, no gain is applied to the signal; however, if the level is set to 0dBm, an attenuation of 10dB is applied. Similarly, if the level is set to -20dBm, a gain of 10dB is applied. If the input level is too low, you should set the expected audio input level to a lower value. For example; if it is set to -10dBm, but the input level is actually - 20dBm, the output will be too low. The range of allowed values depends on the type of device connected and the hardware link settings for the audio compressor circuitry. For a connected radio, the range is -20 dbm to +10 dbm. For a handset or console this value is not configurable and will be set to -10dBm. The default is -10dBm. VoIP/RTP Configuration Select VoIP/RTP in Basic Mode to configure the basic settings for VoIP and RTP as shown in Figure 37. On this page, you can configure settings such as the IP address of the remote IPR device and the port numbers used for sending and receiving data. Figure 37. Basic VoIP / RTP configuration settings IPR100/IPR110Plus Product Manual 53

70 Chapter 3 Basic Settings The basic settings that you can configure on this page include the following: Remote IP Address is the IPv4 address of the remote IPR device, which consists of a valid IPv4 address, a fully-qualified domain name, or a multicast DNS (mdns) name. The default value is the local address of a matching IPR device (see Types of Remote Addressing below). RTP receive port number is the Internet port number that is used for receiving audio and control messages. The allowed value is an even number from 1024 and The default setting is 5004, 5006, 5008 or 5010 depending on the VoIP Channel (see Internet Port Numbers on page 56). RTP transmit port number is the Internet port number that is used for transmitting audio and control messages. The allowed value is an even number from 1026 and The default setting is 5004, 5006, 5008 or 5010 depending on the VoIP Channel (see Internet Port Numbers on page 56). Types of Remote Addressing The IPR device supports three types of address for the Remote IP Address, as discussed below: Numeric Address is an IPv4 address, which consists of 32 bits expressed in a form consisting of four decimal octets separated by periods (dots), called dot-decimal notation. This can be used on a LAN where all the addresses are allocated. Numeric addressing can also be used where a global Internet Address has been allocated and is known. On a local LAN, a common numeric address could be either or You may also use a multicast address (see Multicast Addressing above). The special address disables transmission this can be useful in an IPR110Plus that is using SIP to connect to a dispatch system (see Appendix A, Session Initiation Protocol (SIP) on page 224). Fully Qualified Address is an internet address that uses a fully-qualified domain name, such as ipr100unit3.host.omnitronics.com.au. You can use a domain name only if the IPR device has been configured to use a domain name server (DNS). In this case, the address of the remote IPR device will be allocated by a DNS. This could be the case for an IPR device that is connected to the Internet via an ADSL modem. Multicast DNS Address is an address that includes the suffix.local, such as ipr a2156.local. The IPR device uses a technology called multicast DNS (mdns) to locally discover the addresses of other IPR devices on the local network. In this case, a name can be used to determine the address of the remote device without requiring an external 54 Basic Configuration

71 DNS. However, this can only work on networks that fully support multicasting. IPR devices are factory configured to communicate in matching pairs based on the serial number of each device, as described below: Even-numbered serial number: If the serial number of the IPR device is even, its default IP address is and its default remote VoIP address is Odd-numbered serial number: If the serial number of the IPR device is odd, its default IP address is and its default remote VoIP address is Multicast Addressing Multicast Addressing (multicasting) is a numeric IP addressing scheme that provides an efficient method of sending audio to multiple destinations (a oneto-many transmission). Using multicast addressing, a single data packet is routed to multiple destinations; and the network will only duplicate the packet if it needs to go to several different locations. To configure an IPR device to use multicast addressing, you set the remote address to a numeric multicast address. The IPR device will then join the multicast group associated with this multicast address and will communicate with all devices in the multicast group. For multicast addressing to work effectively, all the network routers in the network must support multicast addressing and have multicasting enabled in their configurations. If your network does not support multicasting, you can use conference modes to provide an alternate solution. For further information about conference mode, refer to Connecting Multiple IPR Devices Using Conference Mode on page 189. Audio received at any IPR device in the multicast group is transmitted once and received by all the other IPR devices in the group. Effectively all the radios or consoles are linked together. If any one IPR device fails, only that IPR device is affected. All the devices are configured to use a single multicast address as the remote address for their VoIP link. For further information about multicast addressing, refer to Appendix A, Multicast Addressing on page 215. Note Many routers on the Internet and some ADSL/DSL modems do not support multicasting. IPR100/IPR110Plus Product Manual 55

72 Chapter 3 Internet Port Numbers An internet port number is part of the IP header and identifies the type of data received or transmitted. The port numbers 5004 and 5005 are allocated for the Real Time Protocol (RTP) and are normally used for VoIP and video data packets. However, the port number may need to be changed to pass through some types of network devices, particularly those that use Network Address Translation (NAT) or Port Forwarding. Also in the case where a VoIP device that can support more than a single connection, such as an Omnitronics IPR400, a separate pair of port numbers is needed for each VoIP connection. 56 Basic Configuration

73 Chapter 4 Advanced Configuration: IPR100 This chapter discusses the advanced settings of the IPR100 product, and includes the following sections: Switching to Advanced Mode Configuring Advanced Network Settings on page 59 Simple Network Management Protocol (SNMP) Settings on page 63 Advanced Radio/Handset Settings on page 65 Advanced VoIP/RTP Settings on page 69 Advanced SIP Settings on page 74 SELCALL/DTMF Settings on page 77 CTCSS Settings on page 80 Serial Data Settings page 83 Changing the Passwords of User Accounts on page 86 Switching to Advanced Mode The advanced configuration mode provides many additional settings and features beyond those available in the basic mode. To use the advanced mode, select Go to ADVANCED mode on the menu as shown in Figure 38. This reloads the current page in your web browser to show the advanced configuration settings for the page. IPR100/IPR110Plus Product Manual 57

74 Chapter 4 Figure 38. Switching to advanced configuration mode of the IPR100 In the advanced mode, the following additional configuration pages appear on the menu: SNMP, SIP, SELCALL/DTMF, CTCSS, Serial Data, and Connections. These pages provide advanced configuration and diagnostics features that are only available in this mode. Many of the configuration pages provide advanced settings. For example, in the advanced mode, the Network Configuration page displays additional settings under the Advanced Settings heading and the Dynamic DNS heading. Some pages, however, do not have any advanced settings so you will see the same settings in advanced mode that you see in basic mode. Note The advanced and basic modes only affect what settings are displayed on the web pages: the basic mode does not disable any advanced mode features or settings. Some advanced configuration pages contain more settings than can fit in the browser window. When this happens, a scrollbar appears so you can scroll the page contents up and down to access all of the settings. 58 Advanced Configuration: IPR100

75 Configuring Advanced Network Settings Figure 39 shows the advanced Network Configuration page that is displayed when you select Network in Advanced Mode. Use this page to configure the advanced network settings of the IPR100. Figure 39. Advanced network configuration page The Network Configuration page consists of two additional sections: Advanced Settings, and Dynamic DNS. It also has a Configuration Status section along the lower edge, which appears on all configuration pages that allow you to make changes to the settings. For information about the basic settings, refer to Configuring the Basic Network Settings on page 43. IPR100/IPR110Plus Product Manual 59

76 Chapter 4 Important If you make any changes to the settings on the Network page, you must save the configuration, and then restart the device for the network changes to take effect. Advanced Settings The Advanced Settings section allows you enable the Universal Plug and Play (UPnP) technology to make it easy for devices to discover each other on the network, and various other advanced settings including the following: Enable UPNP selects the Universal Plug and Play (UPnP) feature, which is network technology that allows the IPR device to be located in the Network folder (see Network Discovery on page 28). Default is enabled. Enable network discovery using Bonjour/mDNS protocol selects the Multicast Domain Name System (mdns) feature, which is a technology that allows devices on a LAN or WAN that supports multicast to provide a domain name instead of an IP Address. mdns automatically converts the domain name to the corresponding IP Address without the need of a dedicated DNS. By enabling this setting, IPR devices can use names rather than IP addresses on local LANs. However, Microsoft Windows does not support mdns. The default setting is enabled. Domain Name System (DNS) Server 1 is the primary Domain Name Server (DNS). The DNS is how an Internet addresses, such as is converted into a numeric (dot-decimal notation) address, like Consult with your ISP or network administrator to determine the correct address. In some cases, the DNS address is the same as the Gateway address. If the VoIP remote address is a numeric value or a local mdns address, you do not need to change this setting. A valid IPv4 address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dot-decimal notation). A value of indicates that no DNS is used. The default setting is (not used). Domain Name System (DNS) Server 2 is the backup DNS that is used in the event the primary DNS is not available. A valid DNS address is the same as described for the setting above. A value of indicates that no DNS is used. The default setting is (not used). Enable Simple Network Management Protocol - SNMP selects the Simple Network Management Protocol (SNMP) feature. SNMP provides a means to extract status information from the IPR100 through a network management system. The IPR100 provides several standard network statistics as well as the site monitoring and control I/O of the IPR100. If you do not intend to use SNMP, this setting should not be selected. This feature is not available in this version of the IPR Advanced Configuration: IPR100

77 Quality of Service: Differentiated Service Class allows the IPR device to mark its VoIP packets as higher priority to ensure they receive preferential treatment when being routed. Consult with your ISP or network manager for more information about the appropriate QOS settings. Allowed values: Default, Expedited Forwarding, Class 1 7, Assured Forwarding 1-1 to Assured Forwarding 4-3. Default is the default setting. Syslog host address is the address used for debugging and diagnosing faults with the IPR100, which can report debug and error information via a network protocol called SYSLOG. This setting is normally set to the default (not used). A valid IPv4 address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dot-decimal notation). A value of indicates that no SYSLOG messages are used. The default is (not used). Dynamic DNS The Dynamic DNS area allows you to configure the DNS settings of the IPR100 and includes the following: Enable Dynamic DNS allows the device to track changes in its public IP address and to update the configured Dynamic DNS host accordingly. Additionally, it performs periodic Domain Name resolution of any configured remote domains and performs required adjustments when a remote end experiences a change in public IP address. Enabling this feature will decrease VoIP down-time when devices sit behind routers of which the IP address can change dynamically. The default is disabled. Important When enabling Dynamic DNS, ensure that the Domain Name System (DNS) Server 1 is configured to an actual DNS server. To enable period DNS resolution only, select this setting and leave all the following settings blank. Public IP Service 1 is a URL to a web service that returns the current public IP address of the requester. It must start with and it is best to verify this in a browser before transferring the URL to this setting. Service 1 acts as the primary IP lookup. Leaving this field blank disables determining the IPR devices public IP address. Default: Not Configured. Public IP Service 2 is similar to Public IP Service 1 except that this will act as the secondary web IP lookup if configured. It will only be used if Service 1 fails. The default is Not Configured. Device Domain Name is the fully qualified domain name of the device. It is this name that is used in all dynamic DNS updates when the device detects a change in the current public IP address. The default is Not Configured. IPR100/IPR110Plus Product Manual 61

78 Chapter 4 Dynamic DNS Host Domain Name is the fully qualified domain name of the server hosting the Dynamic Domain Name service. The server must be the authority with which the Device Domain Name is registered. The default is Not Configured. Dynamic DNS Host Port is the HTTP port (usually 80) of the server hosting the Dynamic Domain Name Service. If port 80 is blocked by a local firewall and if the Dynamic Domain Name Host allows updates via another port, set this accordingly. The default port is 80. Dynamic DNS Host Authentication User Name is the user name required by the dynamic DNS Host for authentication in all updates. The default is Not Configured. Dynamic DNS Host Authentication Password is the password required by the dynamic DNS Host for authentication in all updates. The default is Not Configured. Use the Public IP address for SIP determines whether the public IP address of the device will be used in all SIP conversations. If this setting is not selected, the private IP address will be used. This setting is not selected by default. Using a DHCP Server Select Automatically obtain IP Address (using DHCP) to enable Dynamic Host Configuration Protocol (DHCP), which allows the IPR device to obtain an IP address automatically from a DHCP server. When DHCP is enabled, the static IP address, network gateway address and domain name server settings will be ignored as appropriate values will be provided by the DHCP server; this is the default setting. If you want to assign a static IP address to the IPR100, it is recommended that you allocate an address in the range of to or to as these are especially reserved for private addresses. Note If you want to use the option to Automatically obtain an IP Address (using DHCP), the IPR device will attempt to locate a DHCP server on start up. If it cannot find a server, it will either use the static IP address or automatically assign itself an address in the range x.x. When using a DHCP server to automatically allocate an IP address to the IPR100, the other IP device will not be able to communicate with the IPR100 unless you use multi-casting or local mdns as it will not know the IP address allocated by the DHCP server. 62 Advanced Configuration: IPR100

79 Multicast Addressing is a protocol for efficiently sending data to multiple IPR100 devices at the same time over TCP/IP networks (see Types of Remote Addressing on page 54 for further details). Local mdns name allows you to connect to an IPR100 device by using a local name address instead of an IP address. Local addressing takes the form of name.local, where name is the Location Name configured on the Network settings page. Simple Network Management Protocol (SNMP) Settings Select the SNMP Configuration page shown in Figure 40 to configure the SNMP (Simple Network Management Protocol) settings. Figure 40. SNMP configuration page IPR100/IPR110Plus Product Manual 63

80 Chapter 4 The SNMP configuration of the IPR100 includes the following parameters: Enable SNMP selects the Simple Network Management Protocol (SNMP) feature. SNMP provides a means to extract status information from the IPR100 through a network management system. The IPR100 provides several standard network statistics as well as the site monitoring and control I/O of the IPR100. If SNMP is not being used, this setting should not be selected. For more information about SNMP, refer to Appendix A, Simple Network Management Protocol (SNMP) on page 227. Read community is the SNMP authentication password needed to read (SNMP GET) values from the IPR100. The default community is "public". If left blank, the IPR100 will set this value to "public" when you save the configuration. It is important to note that in order to write (SNMP SET) values to the IPR100 (the digital outputs are the only values allowed), the community "omni" is required. The SET community cannot be changed. Trap destination and Trap destination 2 specify the IP address to which the IPR100 will send SNMP traps. This is also known as an SNMP trap sink address. Generally, it is the IP address of a machine that hosts network management software (NMS). The SNMP Trap destination can only be a valid static IP address. By default, the address is which disables SNMP traps. Enable VoIP statistic traps enables the VoIP SNMP Receive statistic reports section of the page, including the SNMP statistics interval parameter. Selecting this checkbox will enable the IPR100 to send a periodic SNMP trap (defined in the SNMP statistics interval) if either: a) the number of defined RTP Sequence errors is attained; or b) the number of defined RTP Packets too late is attained. Note The counters for each of these conditions will reset every time the SNMP statistics interval has been reached. SNMP statistics interval specifies in seconds when the IPR100 will send an SNMP trap if either: a) the number of defined RTP Sequence errors is attained or; b) the number of defined RTP Packets too late is attained. Note The counters for each of these conditions will reset every time the SNMP statistics interval has been reached. The default value is 900 seconds (15 minutes). VoIP receive sequence errors report threshold and VoIP receive packets too late report threshold defines how many RTP sequence errors or how many RTP packets that arrive too late are permitted within the SNMP statistics interval. 64 Advanced Configuration: IPR100

81 Generally, RTP sequence errors and RTP packets that arrive too late may occur during bad network conditions including slow networks, networks with high packet loss, networks with high packet jitter, or networks with many routers/switches between devices. The default value for these fields is 0 (disabled). Advanced Radio/Handset Settings Figure 41 shows the advanced Radio/Handset configuration page that is displayed when you select the Radio/Handset menu in Advanced Mode. Use this page to configure the basic and advanced network settings of the IPR100. Figure 41. Advanced Radio/Handset configuration page for IPR100 For information about the basic settings, refer to Radio/Handset Settings on page 51. IPR100/IPR110Plus Product Manual 65

82 Chapter 4 IPR100 Advanced Settings The advanced settings you can configure on this page include the following: Audio input compressor enabled enables the audio compressor option on the input audio and will set the audio gain to the correct range for the compressor. This option should only be selected if the hardware link that enables compression is installed (LK9 in position 2-3). The audio compressor circuitry on the IPR100 dynamically changes the volume of the level of the input signal. A popup message similar to one shown below will be displayed to confirm this setting. The default setting is disabled. Note With hardware revision 3.00 and later, LK9 and the Audio Compressor are no longer onboard. For versions prior to revision 3.00, ensure that the value set here matches the hardware link settings for the analog compressor circuitry. If the link settings do not match, the gain will be incorrect. See Table 3 in Differences between Hardware Revisions on page 12. PTT/ Busy Hold/Hang Time (milliseconds) is the length of time that the local radio PTT or Handset Busy output will remain on after a remote device stops requesting it. This ensures that the local radio will not stop transmitting before all audio has been sent. Allowed values: milliseconds. Default: 100 milliseconds Voice Activity Detection option detects when incoming audio is present, and can be used to save bandwidth by only sending data over the network when voice activity is detected. It can also be used to generate a signal to drive the PTT relay at the remote end (see the Remote PTT/Busy Control Mode option below). Default: enabled. VAD hold/hang time is how long (in milliseconds) the IPR100 continues to transmit data or hold PTT on after it detects no voice activity. This is primarily used to ensure that the PTT remains active to keep the remote radio transmitting continuously. Allowed values: milliseconds. Default: 100 milliseconds. 66 Advanced Configuration: IPR100

83 Local PTT keying mode is the method by which the local PTT signal is controlled. The remote tone is based on the state of the remote IPR device's CTCSS detection. The available modes are listed below: Remote Busy/PTT Remote Busy/PTT + tone Fast Key Mode Remote Busy/PTT + tone Normal Key Mode Tone signalling (remote Busy/PTT ignored) The local PTT signal is asserted when a valid remote tone is detected. The state of the remote PTT is ignored. The local PTT signal is asserted as soon as the remote PTT signal is detected. However, if a configured remote tone is not received before the lockout time, the local PTT will be dropped. Use this mode to minimise radio key-up time. The local PTT signal is asserted when both the remote PTT signal is detected and a valid remote tone is detected. If the tone is not detected before the lockout time, then the local PTT signal will not be asserted even if a valid tone is detected. Only the state of the Busy information from the network is used to drive the local PTT signal. When the remote Radio is active, the local PTT will be active regardless of the state of the tone detection. Remote PTT/Busy Control Mode determines how the PTT relay of the remote IPR is activated The allowed methods are listed below: Default: Local-Busy/PTT. None Local-Busy/PTT Local-VAD Don t drive the remote PTT. Drive the remote PTT from the local radio busy or local handset PTT input (the default option). Drive the remote PTT from the voice activity detection. The remote radio will be active while voice is detected at this device Transmit without local BUSY/PTT signal option allows the IPR100 to send audio as data when no control signal is present. This is designed for use with radios that do not provide a busy signal. This mode is usually used with VAD. Default: disabled. Disable PTT/Busy Timeout option disables the timeout setting described below. PTT/Busy Locked on Timeout is the duration after which the IPR100 turns off a PTT (radio) or busy (console/handset) output. This prevents a radio from being locked up in transmit mode. Default: 180 seconds. IPR100/IPR110Plus Product Manual 67

84 Chapter 4 Busy Validation The busy validation settings that you can configure include the following: Enable BUSY Validation allows the IPR100 to validate the busy input (debounce) to ensure it is present for the specified time. The default setting is busy validation disabled. BUSY Validation Time is the duration (in milliseconds) for busy validation: the state of the busy signal will be ignored for this period, and no busy state or audio will be sent to the network. The allowed values are 0 to 1000 milliseconds. The default setting is 20 milliseconds. Enable BUSY Audio Delay option is used to impose an audio delay (of the same duration as the BUSY Validation Time) on the play out of received audio. This will ensure that the received audio is in sync with the validated busy output, as shown in Figure 42. Figure 42. Audio delay timing diagram Trunk Radio Audio Delay Mode You can configure the IPR100 to provide delayed voice audio with respect to PTT. This is a key factor in linking conventional radios with trunk radios. It allows the call setup to take place without losing the first few syllables of speech. The audio delay settings for trunk radios include the following: Enable Trunk Radio Audio Delay option enables the audio to be delayed prior to transmitting. Default: disabled. Trunk Audio Delay Time is the delay (in milliseconds) imposed on the audio before it is transmitted to the device. Allowed Values: ms. Default: Advanced Configuration: IPR100

85 Advanced VoIP/RTP Settings Select the VoIP/RTP menu to configure the advanced settings for VoIP and RTP features. Figure 43 shows the settings on the VoIP Configuration page. This page allows you to configure the basic and advanced settings of the VoIP and RTP. Figure 43. VoIP/RTP advanced configuration For information about the basic settings, refer to VoIP/RTP Configuration on page 53. Advanced Settings The settings that you can configure under Advanced Settings on this page include the following: IPR100/IPR110Plus Product Manual 69

86 Chapter 4 Transmit Codec is the encoding scheme used to encode the audio data for transmission to the remote device. This setting only affects the audio sent. This IPR device will determine the type of codec used by the remote device and decode the audio even if a different codec is used. The following codecs are supported: G.711 PCMU (default), G.711 PCMA, G ADPCM, or GSM (see Supported Codecs on page 72 for a description of each codec). Note Different versions of IPR devices and VoIP phones can support different codec types. The IPR100 product does not support G.729 or G codecs. IP Time To Live (TTL) determines the number of network routers that will pass on the data packets from this unit. This value limits how far the message will be sent. Typically as a router forwards a data packet, it will decrease the TTL information in the data packet, and once the TTL reaches zero, the message will no longer get forwarded. The allowable values are 1 to 255. The default value is 1. When using multicasting, the TTL value indicates the scope or range in which a packet may be forwarded. When configuring an IPR device to use multicasting, it is important to consult with the IT department that manages the network infrastructure to make sure an appropriate value is used. The following pre-defined values are used by convention: TTL = 0 TTL = 1 TTL = 32 TTL = 64 TTL = 128 TTL = 225 Restricted to the same host Restricted to the same subnet Restricted to the same site Restricted to the same region Restricted to the same continent Unrestricted Minimum jitter buffer size sets the delay in milliseconds imposed on the received audio. If the IPR100 is used on a network in which variations in packet delay occur, increasing this value to match the maximum likely delay should improve the quality of the audio. The larger this value is set, the more delay is imposed on the received audio. The allowed values are 20 to 1000 milliseconds. The default value is 20 milliseconds. Maximum jitter buffer size sets the maximum acceptable audio delay (in milliseconds), for received audio. The IPR100 will automatically adjust the delay (depending on network conditions) to the smallest possible value, thus reducing the received audio delay to the minimum that the network can support. The allowed values are: 100 to 2000 milliseconds. The default value is 500 milliseconds. 70 Advanced Configuration: IPR100

87 Note The Maximum Jitter Buffer Size must be greater than or equal to the Minimum Jitter Buffer Size. RTCP Interval/Timeout specifies the period (in seconds) when the RTCP packets are sent. The VoIP link consists of voice data and control information. The control information is provided by the Real Time Control Protocol (RTCP) where packets are periodically sent to provide a heartbeat that maintains the VoIP connection. This parameter must be set identically on both devices that have a VoIP link is established. If multicasting is used, all devices in the multicast group must have this parameter set identically. Reducing the value of this parameter has the effect of reducing the time in detecting a link disconnection with the associated disadvantage of increasing the required Ethernet bandwidth. Alternatively, increasing the value of this parameter reduces the required Ethernet bandwidth and increases the time to detect a link disconnection. An increased RTCP interval may be useful in data bandwidth critical application such as a VoIP link through the 3G mobile phone network. The allowed values are 1 to 120 seconds. The default value is 5 seconds. BUSY/PTT periodic transmit disable option disables the periodic transmission of Busy and PTT status information. In normal operation, the IPR device will send the state of the Busy input and Push-To-Talk output to all connected devices to ensure that the current state is always correct. However, in some scenarios, such as expensive satellite IP links, it may be desirable to disable this feature. In this case, Busy and PTT changes are only sent when the state of the input or output actually changes. BUSY/PTT periodic transmit time determines the period (in seconds) at which the IPR device sends the state of its Busy input and Push-To-Talk output to connected VoIP devices. Enable encryption allows the IPR to encrypt the network data so that a third party is unable to intercept and listen in to conversations. Using an encryption algorithm allows the IPR to encrypt all voice and control data. The IPR100 provides two algorithms: DES and AES. The DES algorithm is an older and less-secure algorithm with a secret key that is 56-bits long. The AES algorithm is a newer algorithm that has a key length of 128 bits, making it more secure. Due to export restrictions, only devices with DES encryption can be exported from Australia. As a result, international IPR devices support only the DES encryption standard. The allowed values are listed below: IPR100/IPR110Plus Product Manual 71

88 Chapter 4 Encryption Disabled Encryption Enabled AES 128 Encryption Enabled DES Do not use data encryption (Default) Use AES 128-bit encryption Use DES 56-bit encryption Encryption key is the string that is used to encrypt the data. This ensures that no third party can decrypt the VoIP data. If this field is blank, the default encryption is used; this ensures backward compatibility with earlier versions of IPR100 firmware (version 1.24 and earlier). The encryption key is case-sensitive. Important If encryption is enabled, then all communicating IPR devices must have encryption enabled and must be configured with the exact same encryption type and encryption key; otherwise the IPR devices will not be able to communicate and the external VoIP indicator will not illuminate. Enable half-duplex mode option enables or disables the half-duplex mode of operation. In this mode, while the device is generating an active Push To Talk output, and sending audio to the radio, the Busy input signal and any received audio from the radio are ignored. Use this mode when you want to block out the received audio while transmitting. Supported Codecs Table 8 lists the codecs that are supported by the IPR100 device. Table 8.

89 VoIP Conference Mode Under the Conference Mode settings shown in Figure 44, you can configure the IPR100 to connect with multiple IP devices in conference mode. This allows several radios or consoles to be connected together in a conference or party-line mode. For further information about the applications of conference mode, refer to Connecting Multiple IPR Devices Using Conference Mode on page 189. Figure 44. VoIP conference mode settings Various configurations are provided for linking the radios together depending on the network and the radio set up. The IPR100 can support up to four devices connected together in a conference mode in addition to the remote device. Other devices that can be connected to a conference include the IPR100, IPR110Plus, DX64 IPE, the DX64CC and DX64CSD consoles. Note Conference mode affects audio, DTMF, SELCALL, and CTCSS (sub-audible) tones.. The Conference Mode configuration includes the following settings: Enable Conferencing enables the conferencing mode. Default is disabled. Conference Mode selects the type of conference mode (see Table 9); and it determines if the audio is linked or retransmitted to the other devices in the conference. The default setting is Peer to peer: No central server. Note Conference mode does not affect the serial pass-through mode. Enable associates the IP address and port configuration for conferencemode transmissions. The default value is disabled. IP Address is the IPv4 address for this conference (i.e., the IPv4 address of the remote IPR device). As for the VoIP remote address, this can be a numeric (dot-decimal notation) IPv4 address or a domain name. Allowed values are a valid remote VoIP address. The default is to IPR100/IPR110Plus Product Manual 73

90 Chapter 4 Transmit Port is the IP port number that is used for transmitting audio and control messages. As for the VoIP Transmit Port, two consecutive ports are used: the first port is for the actual audio data, and the second port is for control and status information. Allowed value is an even number from 1026 to The default port is In conference mode, several radios or consoles can be connected together in a conference so that when any radio or console in the conference receives audio, it is transmitted to all, or some of the other devices, in the conference. Table 9 lists the available conference modes. Table 9. VoIP Conference Modes Mode Peer to Peer: No Central Server Bridge Server: Audio Linked Dispatch Server: Audio not Linked Gateway: Audio Linked Description All IPR devices communicate with all the other IPR devices (see Peer-to-Peer on page 190). All IPR devices communicate with this IPR which forwards the audio to all remote devices (see Bridge Server on page 196). All IPR devices communicate with this IPR. This IPR does not forward any of the remote audio (see Dispatch Server on page 199). IPR devices communicate with this IPR device via a gateway router or server. This IPR forwards audio to/from the remote connection (see Multicast Gateway on page 202). For further information about conference mode configurations, refer to Connecting Multiple IPR Devices Using Conference Mode on page 189. Advanced SIP Settings Select SIP in Advanced Mode to display the settings on the Session Initiation Protocol (SIP) configuration page, as shown in Figure 45. The SIP implemented in the IPR100 is used for terminating two-party (unicast) sessions only. The IPR100 supports inbound connections from other Omnitronics IPR products, such as the IPR110Plus, IPRMon, and IPRDispatch. The IPR device also supports the transmission of audio over VoIP links established by a SIP session; however, this feature can be disabled by setting the VoIP address to in the Remote IP Address basic setting (see Basic Settings on page 54). For further information about SIP, refer to Session Initiation Protocol (SIP) in Appendix A, Technical Reference on page Advanced Configuration: IPR100

91 Figure 45. SIP configuration settings SIP Settings The settings available under SIP Settings include the following: Enable SIP enables support for Session Initiation Protocol. Selecting this option will allow the IPR device to accept incoming connections from other Omnitronics products, such as the IPR100+, IPRMon, and IPRDispatch. The default setting is disabled. SIP UDP Port is the port number used for SIP connections. The allowed values are 1025 to The default value of 5060 is the port assigned by the Internet standards body for SIP. Note The SIP Port must match the setting used by the device that will connect to the IPR100; and the value must be different to the port numbers used by the VoIP/RTP configuration. Default Transport Protocol is the default transport protocol used for transmitting SIP messages. The IPR100 supports both the User Datagram Protocol (UDP) and Transmission Control Protocol (TCP). This option is for compatibility with devices and servers that only support one of these transport protocols. IPR100/IPR110Plus Product Manual 75

92 Chapter 4 Regardless of the value of this setting, the IPR100 will correctly respond to SIP messages sent to it using both UDP and TCP transport protocols. Allowed values are: UDP - User Datagram Protocol, TCP - Transmission Control Protocol. The default is: UDP - User Datagram Protocol. Note The Default Transport Protocol setting may not appear on the configration page as it depends on the firmware version installed in your IPR100. Only firmware versions 5.13 and later support both the UDP and TCP transport protocols, whereas, firmware versions older than this only support the UDP transport protocol. This setting does not appear for the older firmware. User Name is the name that is used to validate an incoming SIP connection. If an incoming SIP connection does not have the correct user name it will be rejected. A valid user name may consist of alphanumeric characters (no spaces or punctuation characters allowed). The default name is group1. Enable status sounds allows the IPR100 to play a distinctive sound when a SIP connection is established or disconnected (see Table 13 on page 111). Push-to-talk is activated automatically while the audio is played. The delays for DTMF/SELCALL lead-in and lead-out are used to control the PTT lead-in and lead-out. The default value is disabled. Disable changing transmit CODEC type option prevents the IPR device from changing the code type used to transmit audio when a SIP connection is received; the codec type used is specified on the VoIP/RTP configuration page. If this option is not selected, the IPR device may change the codec type used to transmit audio when a SIP connection is received. Select this option in situations when the configured codec should not be changed, such as, when the GSM codec has been selected for the main VoIP link to reduce bandwidth usage; the IPR device will still accept and decode received RTP audio packets that use a different codec type. 76 Advanced Configuration: IPR100

93 SELCALL/DTMF Settings Select SELCALL/DTMF in Advanced Mode to view the configuration page for the SELCALL and DTMF settings, as shown in Figure 46. The IPR100 supports SELCALL and DTMF by detecting the tone, encoding it as a data packet and sending it to a remote device. This enables SELCALL and DTMF to be sent on links with GSM or other compressing codec. Each of the sections on this page is discussed below. Figure 46. DTMF and SELCALL settings General The configuration settings under the General section include the following: Tone Transmit Level is the output level for transmitting both SELCAL and DTMF tones to locally installed equipment. This level does not affect (nor is affected by) the audio transmit level. The allowed values are -10 to +10dB. The default setting is 0dB. IPR100/IPR110Plus Product Manual 77

94 Chapter 4 Lead In Delay (10 x milliseconds) is the length of time that the IPR100 asserts the PTT before starting to transmit a SELCAL or DTMF tone. This is to ensure the radio is on and transmitting correctly before the tone is transmitted. The allowed values are 2 to 255 (20 to 2550 milliseconds). The default value is 100 (1 second). Lead Out Delay (10 x milliseconds) is the length of time that the IPR100 holds the PTT on after sending a DTMF or SELCAL tone. This is to ensure the radio does not turn off before the whole tone has been received. The allowed values are 2 to 255 (20 to 2550 milliseconds). The default value is 50 (500 milliseconds). DTMF The configuration settings under the DTMF section include the following: DTMF Detection option enables local detection of DTMF and uses the value in DTMF Tone Period (in milliseconds. If this is selected, the IPR device will locally listen for and decode DTMF tones. When it receives a valid DTMF tone, it will encode it as a data packet and send it to the remote IPR device. At the remote IPR device, when the data packet is received, it will generate a corresponding DTMF tone sequence. The default value is disabled. DTMF Tone Period (in milliseconds) is the duration of the Tone and Silence periods is used for generating DTMF signals. It may be necessary select the DTMF Detection option above with some equipment that has slow detection periods. The allowed values are 50 and 100 milliseconds. The default value is 100 milliseconds. SELCALL (Selective Calling) The configuration settings under the SELCALL (Selective Calling) section include the following: SELCALL Detection option enables local detection of SELCALL. If this is selected, the IPR device will locally look for and decode SELCALL tone sequences. When it receives a valid SELCALL sequence, it will encode it as a data packet and send it to the remote IPR device. At the remote IPR device, the data packet will be received and the remote IPR device will generate a SELCALL sequence with the same numbers. The default value is disabled. SELCALL Scheme specifies the type of SELCALL scheme in use. The supported SELCALL schemes are EEA, ZVEI1, ZVEI2, ZVEI3, PZVEI, CCIR, EIA and DZVEI. The default setting is CCIR. 78 Advanced Configuration: IPR100

95 Number of Tones is the number of tones and gaps in a valid SELCALL sequence. The allowed values are 1 to 20. Default number of tones is 5. SELCALL Tone Period (milliseconds) is the duration in milliseconds of each tone in the sequence. The allowed values are 20 to 100 milliseconds. The default is 20 milliseconds. Tone Position and Type The settings on the DTMF/SELCALL page available under the Tone Position and Tone Type headings include the following: Tone Position and Type shows the position of each configured tone and the how the tone is configured: the IPR100 can be configured to detect a particular tone or silence duration. The possible values are: Tone: Normal Period Tone: Extended Period Silence: Normal Period Specifies a tone that is equal in duration to the period of the configured tone. Specifies a tone that is twice the duration of the period of the configured tone. Specifies a period of silence that is equal in duration to the period of the configured tone. Silence: Extended Period Specifies a period of silence that is twice the duration of the period of the configured tone. When configuring these settings, several rules are applied to ensure the tone sequence is valid: the first and last tone positions must be configured as a tone, and an extended tone period can only be configured in a position after a silence period. IPR100/IPR110Plus Product Manual 79

96 Chapter 4 CTCSS Settings Figure 47 shows the settings for the CTCSS configuration page when you select CTCSS in Advanced Mode. Figure 47. CTCSS configuration settings Tone Detection The configuration settings available under Tone Detection include the following: Enable Tone Detection/Transmission option allows the IPR100 to detect CTCSS tones and transmit them to the network as data packets. The default setting is unselected (Tone Detection/Transmission disabled). 80 Advanced Configuration: IPR100

97 CTCSS Signal Path determines the path of the CTCSS tones. The IPR100 voice circuitry includes a high-pass filter so that CTCSS tones will not be sent as audio data. The allowed values are CTCSS In-Band or CTCSS External. The default setting is CTCSS In-Band. Note An external CTCSS signal path is provided via the 25-way AUX (digital I/O) connector on the back panel of the IPR100/110Plus. Enable high-pass filter for audio enables a high-pass filter in the DSP that will remove the CTCSS tones from the audio path. The default setting is unselected (High-pass audio filter disabled). Tone Detection Validation Time (milliseconds) is the period (in milliseconds) that a frequency must be present and detected before it is considered a valid tone. Setting this time for a longer period will make the CTCSS tone detection more reliable but will increase the delay for propagating the CTCSS information. The allowed values are 10 to 1000 milliseconds. The default is 150 milliseconds. Local Keying and Tone Transmission The configuration settings available under Local Keying and Tone Transmission include the following: Transmit Level is the level of attenuation applied to the locally generated CTCSS tone. It is independent of transmit audio and transmit SELCALL/DTMF levels. Allowed values: -10 to +10dB. The default setting is Tx Gain 0 db. PTT keying mode is the method by which the local PTT signal is controlled. The available modes are listed below: CTCSS Ignored CTCSS Fast Key Mode Only the state of the Busy information from the network is used to drive the local PTT signal. When the remote Radio is active, the local PTT will be active regardless of the state of the CTCSS detection. The local PTT signal is asserted as soon as the remote PTT signal is detected. However, if a configured remote CTCSS tone is not received before the CTCSS lockout time, the local PTT will be dropped. This mode is used to minimise the time taken to key up a radio. IPR100/IPR110Plus Product Manual 81

98 Chapter 4 CTCSS Normal Key Mode CTCSS Only Mode The default setting is CTCSS Ignored. The local PTT signal is asserted when both the remote PTT signal is detected and a valid remote CTCSS tone is detected. If the CTCSS tone is not detected before the CTCSS lockout time, then the local PTT signal will not be asserted even if a valid CTCSS tone is detected. The local PTT signal is asserted when a valid remote CTCSS tone is detected. The state of the remote PTT is ignored. CTCSS Lockout Time (milliseconds) is the timeout period (in milliseconds) used in fast keying mode and normal keying mode. If a remote CTCSS is not detected within this period when the remote PTT signal is detected, the local PTT signal will not be activated. The default setting is Enabled Frequencies The IPR device can detect up to 33 CTCSS frequencies simultaneously and generate one at a time. The frequencies that the IPR device can detect and generate (in Hz) are listed below: 67.0, 69.3, 71.9, 74.4, 77.0, 79.7, 82.5, 85.4, 88.5, 91.5, 94.8, 97.4, 100.0, 103.5, 107.2, 110.9, 114.8, 118.8, 123.0, 127.3, 131.8, 136.5, 141.3, 146.2, 151.4, 156.7, 159.8, 162.2, 167.9, 173.8, 179.9, 183.5, 186.2, 189.9, 192.8, 196.6, 199.5, 203.5, 206.5, 210.7, 218.1, 225.7, 229.1, 233.6, 241.8, 250.3, Note To enable a frequency, select the check box next to the frequency. If you attempt to enable more than 32 frequencies, an alert message is displayed. For a CTCSS tone to be correctly detected and transmitted, that frequency must be enabled on both IPR100/110Plus devices, i.e., on both the detecting and the transmitting IPR100/110Plus. CTCSS Talk OFF Time out The IPR device will hold on the receive CTCSS frequency for a talk off time of 2000 milliseconds; i.e., the CTCSS frequency must be undetected for 2000 milliseconds before the indication is dropped. This is to stop the CTCSS indication being dropped during speech. 82 Advanced Configuration: IPR100

99 However, when either CTCSS Fast Key Mode or CTCSS Normal Key Mode is used, if the radio mute becomes inactive, the CTCSS indication will be dropped immediately. Serial Data Settings Select the Serial Data menu in Advanced Mode to access the settings on the Serial Data configuration page as shown in Figure 48. This page contains the settings for configuring the RS232 serial port (DCE) on the rear panel of the IPR100. Figure 48. Serial Data configuration showing the Serial Pass-Through settings IPR100/IPR110Plus Product Manual 83

100 Chapter 4 The serial port supports two modes of operation: Serial Pass-Through mode and Serial Monitor mode; however, only one of these modes can be in use at one time. Serial Pass-Through Mode provides a transparent link that can be used to connect RS232 devices over the Internet. Support for multi-drop serial communications is provided for seven additional remote destination addresses. All serial and flow control data is sent to all the remote addresses. Serial Monitor Mode is not intended for normal use, but is intended only for technicians or Omnitronics support engineers to assist in initial configuration, diagnosing problems, and troubleshooting. For further information, refer to Chapter 7, Serial Monitor. Serial Pass-Through Mode The IPR100 provides the ability to transmit and receive RS232 data between a pair of IPR devices. This uses a UDP connection between the two units to tunnel RS232 data over the network. Enabling the Serial Data Pass-Through mode disables the Serial Monitor mode on the serial port. The serial passthrough function of the IPR100 is compatible with both the IPR110Plus and the IPR400. It includes the following settings: Enable Serial Pass Through Mode selects the serial data pass-through mode and disables the serial monitor mode on the serial port. The default is disabled. Note If Serial Pass-Through mode is enabled, Serial Monitor mode is disabled. Remote IP Address is the IP address of the remote IPR100 to which the serial data will be sent. Like the remote VoIP address settings, this can be a 32-bit IPv4 address or a domain name. The default is Note The Remote Address does not need to be the same as the VoIP Remote Address, which means that the serial pass-through mode can be used to send serial data to any valid IP address. UDP Port Number specifies the TCP/IP port number that is used for sending the data, which must be set to the same value on both IPR100 devices. The allowed values are 1024 to The default setting is Table 10 lists the compatibility of the serial pass-through mode between the IPR100, IPR110Plus, and the IPR Advanced Configuration: IPR100

101 Table 10. Compatibility of the Serial Pass-Through Protocol Serial Pass-Through IPR100 IPR110Plus Protocol (Local/Int l) (Local/Int l) IPR400 (Local/Int l) Original 4.14/ i 4.14/ i 3.06/ i New 5.00/ i 5.00/ i 3.07/ i The original serial pass-through protocol existed up to version 4.14/ i of the IPR100 and IPR110Plus firmware and up to version 3.06/ i for the IPR400. The protocol changed to support the multi-drop feature, which was implemented in version 5.00/ i of the IPR100 and IPR110Plus and version 3.07/ i of the IPR400. Therefore, the incompatibility to previous versions lies at version 5.00/ i of IPR device and version 3.07/3/07.02i of the IPR400. Version 5.00/ i of the IPR device and version 3.07/3/07.02i of the IPR400 are compatible with each other. This change in protocol is hardware independent allowing devices in the field to be upgraded to the latest firmware version and therefore support the latest serial protocol. Serial Port Parameters The following settings must match the serial settings of the device connected to the serial port of the IPR100. Baud Rate is the serial data rate in bits per second. The allowed values are: 1200, 2400, 4800, 9600, 19200, and The default is Data Bits specifies the number of bits in the data. The allowed values are 7 or 8. The default is 8. Stop Bits specifies the number of bits used to designate the end of the data. The allowed values are 1 or 2. The default is 1. Parity is a basic error-detection scheme. The allowed values are: None, Odd or Even. The default is None. Flow Control specifies the method used to control the flow of data. The allowed values are None, XON/XOFF or RTS/CTS. Default is None. Inter character timeout controls how the RS232 data is collected and transmitted over the network. When the IPR device starts receiving data, it will keep collecting data until it gets a time-out or the maximum message length is reached. The allowed values are 1 to 1000 milliseconds. The default is 100 milliseconds. Note If you set the timeout too long, communication will be very slow. IPR100/IPR110Plus Product Manual 85

102 Chapter 4 Maximum Message Length is the largest block of data (in bytes) that will be sent over the network in a single packet. The allowed values are 4 to The default is Multi-Drop Mode The configuration settings available under Multi-drop Mode include the following: Enable multi-drop mode enables the ability to send data to multiple remote IPR devices. Multi-drop Address 1 Multi-drop Address 7 are used to specify the address to use for the corresponding multi-drop address. Simply type the multi-drop address you want to use in the appropriate text boxes.

These items provide advanced configuration features that are only available in this mode. IPR100/IPR110Plus Product Manual 91

108 Chapter 5 Note The advanced and basic modes only affect what settings are displayed on the web pages: basic mode does not disable any advanced features or settings. All of the Diagnostic pages with the exception of the Connections page (only available in advanced mode) are the same in both modes. Figure 52. Advanced configuration mode of the IPR110Plus Some advanced configuration pages contain more settings than can fit in the browser window. When this happens, a scrollbar appears so you can scroll the page contents up and down to access all of the settings. Configuring the Advanced Network Settings Figure 53 shows the advanced Network Configuration page that is displayed when you select the Network menu in Advanced Mode. Use this page to configure the advanced network settings of the IPR110Plus. In advanced mode, the Network Configuration page includes two additional sections: Advanced Settings, and Dynamic DNS. It also has a Configuration Status section along the lower edge, which appears on all configuration pages that allow you to make changes to the settings. For information about the basic settings, refer to Configuring the Basic Network Settings on page Advanced Configuration: IPR110Plus

109 Figure 53. Advanced network configuration page Important If you make any changes to the settings on the Network Configuration page, you must save the configuration, and then restart the device for the network changes to take effect. Advanced Settings The Advanced Settings section allows you enable the Universal Plug and Play (UPnP) technology to make it easy for devices to discover each other on the network, and various other advanced settings including the following: Enable UPNP selects the Universal Plug and Play (UPnP) feature, which is a networking technology that allows devices to work together with fewer configurations. By enabling UPnP, the IPR110Plus will be displayed in the Network Neighborhood on a Microsoft Windows XP or Vista computer. The default setting is enabled. IPR100/IPR110Plus Product Manual 93

110 Chapter 5 Enable network discovery using Bonjour/mDNS protocol selects the Multicast Domain Name System (mdns) feature, which is a technology that allows devices on a LAN or WAN that supports multicast to provide a domain name instead of an IP Address. mdns automatically converts the domain name to the corresponding IP Address without the need of a dedicated DNS. By enabling this setting, IPR devices can use names rather than IP addresses on local LANs. However, Microsoft Windows does not support mdns. The default setting is enabled. Domain Name System (DNS) Server 1 is the primary Domain Name Server (DNS). The DNS is how an Internet addresses, such as is converted into a numeric (dot-decimal notation) address, like Consult with your ISP or network administrator to determine the correct address. In some cases, the DNS address is the same as the Gateway address. If the VoIP remote address is a numeric value or a local mdns address, you do not need to change this setting. A valid IPv4 address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dot-decimal notation). A value of indicates that no DNS is used. The default setting is (not used). Domain Name System (DNS) Server 2 is the backup DNS that is used in the event the primary DNS is not available. A valid DNS address is the same as described for the setting above. A value of indicates that no DNS is used. The default setting is (not used). Enable Simple Network Management Protocol - SNMP selects the Simple Network Management Protocol (SNMP) feature. SNMP provides a means to extract status information from the IPR110Plus through a network management system. The IPR110Plus provides several standard network statistics as well as the site monitoring and control I/O of the IPR110Plus. If SNMP is not being used, this setting should not be selected. This feature is not available in this version of the IPR110Plus. Quality of Service: Differentiated Service Class allows the IPR110Plus to mark its VoIP packets as higher priority to ensure they receive preferential treatment when being routed. Consult with your ISP or network manager for more information about the appropriate QOS settings. Allowed values: Default, Expedited Forwarding, Class 1 7, Assured Forwarding 1-1 to Assured Forwarding 4-3. Default is the default setting. Syslog host address is the address used for debugging and diagnosing faults with the IPR110Plus, which can report debug and error information via a network protocol called SYSLOG. This setting is normally set to the default (not used). A valid IPv4 address consists of 32 bits, expressed in a form consisting of four decimal octets separated by periods (dot-decimal notation). A value of indicates that no SYSLOG messages are used. The default is (not used). 94 Advanced Configuration: IPR110Plus

111 Dynamic DNS The Dynamic DNS area allows you to configure the DNS settings of the IPR110Plus and includes the following: Enable Dynamic DNS allows the device to track changes in its public IP address and to update the configured Dynamic DNS host accordingly. Additionally, it performs periodic Domain Name resolution of any configured remote domains and performs required adjustments when a remote end experiences a change in public IP address. Enabling this feature will decrease VoIP down-time when devices sit behind routers of which the IP address can change dynamically. The default is disabled. Note When enabling Dynamic DNS, ensure that the Domain Name System (DNS) Server 1 is configured to an actual DNS server. To enable period DNS resolution only, select this setting and leave all the following settings blank. Public IP Service 1 is a URL to a web service that returns the current public IP address of the requester. It must start with and it is best to verify this in a browser before transferring the URL to this setting. Service 1 will act as the primary web IP lookup. Leaving this field blank will disable determining the IPR devices public IP address. The default is Not Configured. Public IP Service 2 is similar to Public IP Service 1 except that this will act as the secondary web IP lookup if configured. It will only be used if Service 1 fails. The default is Not Configured. Device Domain Name is the fully qualified domain name of the device. It is this name that is used in all dynamic DNS updates when the device detects a change in the current public IP address. The default is Not Configured. Dynamic DNS Host Domain Name is the fully qualified domain name of the server hosting the Dynamic Domain Name service. The server must be the authority with which the Device Domain Name is registered. The default is Not Configured. Dynamic DNS Host Port is the HTTP port (usually 80) of the server hosting the Dynamic Domain Name Service. If port 80 is blocked by a local firewall and if the Dynamic Domain Name Host allows updates via another port, set this accordingly. The default port is 80. Dynamic DNS Host Authentication User Name is the user name required by the dynamic DNS Host for authentication in all updates. The default is Not Configured. IPR100/IPR110Plus Product Manual 95

112 Chapter 5 Dynamic DNS Host Authentication Password is the password required by the dynamic DNS Host for authentication in all updates. The default is Not Configured. Use the Public IP address for SIP determines whether the public IP address of the device will be used in all SIP conversations. If this setting is not selected, the private IP address will be used. This setting is not selected by default. Using a DHCP Server Select Automatically obtain IP Address (using DHCP) to enable Dynamic Host Configuration Protocol (DHCP), which allows the IPR110Plus to obtain an IP address automatically from a DHCP server. When DHCP is enabled, the static IP address, network gateway address and domain name server settings will be ignored as appropriate values will be provided by the DHCP server; this is the default setting. If you want to assign a static IP address to the IPR110Plus, it is recommended that you allocate an address in the range of to or to as these are especially reserved for private addresses. Note If you want to use the option to Automatically obtain an IP Address (using DHCP), the IPR110Plus will attempt to locate a DHCP server on start up. If it cannot find a server, it will either use the static IP address or automatically assign itself an address in the range x.x. In this case, the IPR110Plus will take an additional seconds to startup whilst waiting for a DHCP server to respond. When using a DHCP server to automatically allocate an IP address to the IPR device, the other IP device will not be able to communicate with it unless you use multi-casting or local mdns as it will not know the IP address allocated by the DHCP server. Multicast Addressing is a protocol for efficiently sending data to multiple IPR110Plus devices at the same time over TCP/IP networks (see Types of Remote Addressing on page 54 for further details). Local mdns name allows you to connect to an IPR110Plus device by using a local name address instead of an IP address. Local addressing takes the form of name.local, where name is the Location Name configured on the Network settings page. 96 Advanced Configuration: IPR110Plus

113 Simple Network Management Protocol Select the SNMP Configuration page shown in Figure 54 to configure SNMP (Simple Network Management Protocol) settings. Figure 54. SNMP configuration page The SNMP configuration of the IPR110Plus includes the following parameters: Enable SNMP selects the Simple Network Management Protocol (SNMP) feature. SNMP provides a means to extract status information from the IPR110Plus through a network management system. The IPR110Plus provides several standard network statistics as well as the site monitoring and control I/O of the IPR110Plus. If SNMP is not being used, this setting should not be selected. For more information about SNMP, refer to Appendix A, Simple Network Management Protocol (SNMP) on page 227. Read community is the SNMP authentication password needed to read (SNMP GET) values from the IPR110Plus. The default community is "public". If left blank, the IPR110Plus will set this value to "public" when you save the configuration. It is important to note that in order to write (SNMP IPR100/IPR110Plus Product Manual 97

114 Chapter 5 SET) values to the IPR110Plus (the digital outputs are the only values allowed), the community "omni" is required. The SET community cannot be changed. Trap destination 1 and Trap destination 2 specify the IP address to which the IPR110Plus will send SNMP traps. This is also known as an SNMP trap sink address. Generally, it is the IP address of a machine that hosts network management software (NMS). The SNMP Trap destination can only be a valid static IP address. By default, the address is which disables SNMP traps. Enable VoIP statistic traps enables the VoIP SNMP Receive statistic reports section of the webpage, including the SNMP statistics interval parameter. Selecting this checkbox will enable the IPR110Plus to send a periodic SNMP trap (defined in the SNMP statistics interval) if either: a) the number of defined RTP Sequence errors is attained; or b) the number of defined RTP Packets too late is attained. Note The counters for each of these conditions will reset every time the SNMP statistics interval has been reached. SNMP statistics interval specifies in seconds when the IPR110Plus will send an SNMP trap if either: a) the number of defined RTP Sequence errors is attained; or b) the number of defined RTP Packets too late is attained. Note The counters for each of these conditions will reset every time the SNMP statistics interval has been reached. The default value is 900 seconds (15 minutes). Advanced Radio/Handset Settings Figure 55 shows the advanced Radio/Handset configuration page that is displayed when you select the Radio/Handset menu in Advanced Mode. Use this page to configure the basic and advanced network settings of the IPR110Plus. For information about the basic settings, refer to Radio/Handset Settings on page Advanced Configuration: IPR110Plus

115 Figure 55. Advanced Radio/Handset settings for IPR110Plus IPR110Plus Advanced Settings The advanced settings that you can configure on this page include the following: Audio input compressor enabled enables the audio compressor option on the input audio and will set the audio gain to the correct range for the compressor. This option should only be selected if the hardware link that enables compression is installed (LK9 in position 2-3). The audio compressor circuitry on the IPR110Plus dynamically changes the volume of the level of the input signal. A popup message similar to one shown below will be displayed to confirm this setting. The default setting is disabled. IPR100/IPR110Plus Product Manual 99

116 Chapter 5 Note On hardware revision 3.00 and later, LK9 and the Audio Compressor are no longer on board. For versions prior to revision 3.00, ensure the value set here matches the hardware link settings for the analog compressor circuitry. If the link settings do not match, the gain will be incorrect (see Table 3 in Differences between Hardware Revisions on page 12). PTT/ Busy Hold/Hang Time (milliseconds) is the length of time that the local radio PTT or Handset Busy output will remain on after a remote device stops requesting it. This ensures that the local radio will not stop transmitting before all audio has been sent. Allowed values: milliseconds. Default: 100 milliseconds Voice Activity Detection option detects when incoming audio is present, and can be used to save bandwidth by only sending data over the network when voice activity is detected. It can also be used to generate a signal to drive the PTT relay at the remote end (see the Remote PTT/Busy Control Mode option below). Default is enabled. VAD hold/hang time(milliseconds) is how long the IPR110Plus continues to transmit data or hold PTT on after it detects no voice activity. This is primarily used to ensure that the PTT remains active to keep the remote radio transmitting continuously. Allowed values: milliseconds. Default: 100 milliseconds. Local PTT keying mode is the method by which the local PTT signal is controlled. The remote tone is based on the state of the remote IPR device's CTCSS detection. The available modes are listed below: Remote Busy/PTT Remote Busy/PTT + tone. Fast Key Mode Remote Busy/PTT + tone. Normal Key Mode The local PTT signal is asserted when a valid remote tone is detected. The state of the remote PTT is ignored. The local PTT signal is asserted as soon as the remote PTT signal is detected. However, if a configured remote tone is not received before the lockout time, the local PTT will be dropped. This mode is used to minimise the time taken to key up a radio. The local PTT signal is asserted when both the remote PTT signal is detected and a valid remote tone is detected. If the tone is not detected before the lockout time, then the local PTT signal will not be asserted even if a valid tone is detected. 100 Advanced Configuration: IPR110Plus

117 Tone signalling (remote Busy/PTT ignored) Only the state of the Busy information from the network is used to drive the local PTT signal. When the remote Radio is active, the local PTT will be active regardless of the state of the tone detection. Remote PTT/Busy Control Mode determines how the PTT relay of the remote IPR is activated The allowed methods are listed below: Default: Local-Busy/PTT None Local-Busy/PTT Local-VAD Don t drive the remote PTT. Drive the remote PTT from the local radio busy or local handset PTT input (the default option). Drive the remote PTT from the voice activity detection. The remote radio will be active while voice is detected at this device Transmit without local BUSY/PTT signal option allows the IPR110Plus to send audio as data when no control signal is present. This is designed for use with radios that do not provide a busy signal. This mode is usually used with VAD. Default: disabled. Disable PTT/Busy Timeout option disables the timeout setting described below. PTT/Busy Locked on Timeout is the duration after which the IPR110Plus turns off a PTT (radio) or busy (console/handset) output. This prevents a radio from being locked up in transmit mode. Default: 180s. Busy Validation The busy validation settings that you can configure include the following: Enable BUSY Validation allows the IPR110Plus to validate the busy input (debounce) to ensure it is present for the specified time. The default setting is busy validation disabled. BUSY Validation Time (milliseconds) is the duration (in milliseconds) for busy validation: the state of the busy signal will be ignored for this period, and no busy state or audio will be sent to the network. The allowed values are 0 to 1000 milliseconds. The default setting is 20 milliseconds. Enable BUSY Audio Delay option is used to impose an audio delay (of the same duration as the BUSY Validation Time) on the play out of received audio. This will ensure that the received audio is in sync with the validated busy output, as shown in Figure 56. IPR100/IPR110Plus Product Manual 101

118 Chapter 5 Figure 56. Audio delay timing diagram BUSY sense invert option inverts the input sense of the BUSY from the radio. That is, it converts the signal from active-high to active-low. Trunk Radio Audio Delay Mode The IPR110Plus can be configured to provide delayed voice audio (with respect to PTT). This is a key factor in allowing conventional radios to be linked with trunk radios. It allows the trunk call setup to take place without losing the first few syllables of speech. The audio delay settings for trunk radios that you can configure include the following: Enable Trunk Radio Audio Delay option enables the audio to be delayed prior to transmitting. Default: disabled. Trunk Audio Delay Time (milliseconds) is the delay imposed on the audio before it is transmitted to the device. Allowed value is ms. Default is 0. Advanced VoIP/RTP Settings Select the VoIP/RTP menu to configure the advanced settings for VoIP and RTP features. Figure 57 shows the settings on the VoIP Configuration page. This page allows you to configure the basic and advanced settings of the VoIP and RTP. For information about the basic settings, refer to VoIP/RTP Configuration on page Advanced Configuration: IPR110Plus

119 Figure 57. VoIP/RTP advanced configuration Advanced Settings The settings that you can configure under Advanced Settings on this page include the following: Transmit Codec is the encoding scheme used to encode the audio data for transmission to the remote device. This setting only affects the audio sent. This IPR device will determine the type of codec used by the remote device and decode the audio even if a different codec is used. The following codecs are supported: G.711 PCMU (default), G.711 PCMA, G ADPCM, or GSM (see Supported Codecs on page 106 for a description of each codec). Note Different versions of IPR devices and VoIP phones can support different codec types. The IPR110Plus product does not support G.729 or G codecs IPR100/IPR110Plus Product Manual 103

120 Chapter 5 IP Time To Live (TTL) determines the number of network routers that will pass on the data packets from this unit. This value limits how far the message will be sent. Typically as a router forwards a data packet, it will decrease the TTL information in the data packet, and once the TTL reaches zero, the message will no longer get forwarded. The allowable values are 1 to 255. The default value is 1. When using multicasting, the TTL value indicates the scope or range in which a packet may be forwarded. When configuring an IPR device to use multicasting, it is important to consult with the IT department that manages the network infrastructure to make sure an appropriate value is used. The following pre-defined values are used by convention: TTL = 0 TTL = 1 TTL = 32 TTL = 64 TTL = 128 TTL = 225 Restricted to the same host Restricted to the same subnet Restricted to the same site Restricted to the same region Restricted to the same continent Unrestricted Minimum jitter buffer size (milliseconds) sets the delay in milliseconds imposed on the received audio. If the IPR110Plus is used on a network in which variations in packet delay occur, increasing this value to match the maximum likely delay should improve the quality of the audio. The larger this value is set, the more delay is imposed on the received audio. The allowed values are 20 to 1000 milliseconds. The default value is 20 milliseconds. Maximum jitter buffer size (milliseconds) sets the maximum acceptable audio delay (in milliseconds), for received audio. The IPR110Plus will automatically adjust the delay (depending on network conditions) to the smallest possible value, thus reducing the received audio delay to the minimum that the network can support. The allowed values are: 100 to 2000 milliseconds. The default value is 500 milliseconds. Note The Maximum Jitter Buffer Size must be greater than or equal to the Minimum Jitter Buffer Size. RTCP Interval/Timeout (seconds) specifies the period when the RTCP packets are sent. The VoIP link consists of voice data and control information. The control information is provided by the Real Time Control Protocol (RTCP) where packets are periodically sent to provide a heartbeat that maintains the VoIP connection. This parameter must be set identically on both devices that establish a VoIP link. If multicasting is used, all devices in the multicast group must have this parameter set identically. 104 Advanced Configuration: IPR110Plus

121 Reducing the value of this parameter has the effect of reducing the time in detecting a link disconnection with the associated disadvantage of increasing the required Ethernet bandwidth. Alternatively, increasing the value of this parameter reduces the required Ethernet bandwidth and increases the time to detect a link disconnection. An increased RTCP interval may be useful in data bandwidth critical application such as a VoIP link through the 3G mobile phone network. The allowed values are 1 to 120 seconds. The default value is 5 seconds. BUSY/PTT periodic transmit disable option disables the periodic transmission of Busy and PTT status information. In normal operation, the IPR device will send the state of the Busy input and Push-To-Talk output to all connected devices to ensure that the current state is always correct. However, in some scenarios, such as expensive satellite IP links, it may be desirable to disable this feature. In this case, Busy and PTT changes are only sent when the state of the input or output actually changes. BUSY/PTT periodic transmit time determines the period (in seconds) at which the IPR device sends the state of its Busy input and Push-To-Talk output to connected VoIP devices. Enable encryption allows the IPR110Plus to encrypt the network data so that a third party is unable to intercept and listen in to conversations. Using an encryption algorithm and enabling encryption allows the IPR110Plus to encrypt all voice and control data. The IPR110Plus provides two algorithms: DES and AES. The DES algorithm is an older and less-secure algorithm with a secret key that is 56-bits long. The AES algorithm is a newer algorithm that has a key length of 128 bits, making it more secure. Due to export restrictions, only devices with DES encryption can be exported outside of Australia. As a result, international IPR devices support only the DES encryption standard. The allowed values are listed below: Encryption Disabled Encryption Enabled AES 128 Encryption Enabled DES Do not use data encryption (the default setting) Use AES 128-bit encryption Use DES 56-bit encryption Encryption key is the string that is used to encrypt the data. This ensures that no third-party can decrypt the VoIP data. If this field is blank, the default encryption is used; this ensures backward compatibility with earlier versions of IPR110Plus firmware (version 1.24 and earlier). The encryption key is case-sensitive. IPR100/IPR110Plus Product Manual 105

122 Chapter 5 Important If encryption is enabled, then all IPR devices must have encryption enabled and must be configured with the same encryption type and key; otherwise the IPR devices will not be able to communicate and the external VoIP indicator will not illuminate. Enable half-duplex mode option enables or disables the half-duplex mode of operation. In this mode, while the device is generating an active Push To Talk output, and sending audio to the radio, the Busy input signal and any received audio from the radio are ignored. Use this mode when you want to block out the received audio while transmitting. Supported Codecs Table 11 lists the codecs that are supported by the IPR110Plus device. Table 11. Codecs supported by the IPR110Plus Codec G.711 PCMU 8000Hz μ-law (often u-law, ulaw, or mu-law) G.711 PCMA 8000Hz A-law G GSM Description ITU G.711 Pulse Coded Modulation μ-law.

Voice Quality: Good This is GSM Codec. Bandwidth: 13 k bits per second. Voice Quality: Good for Voice but distorts tones and DTMF signals. VoIP Conference Mode Under the Conference Mode settings shown in Figure 58, you can configure the device to connect with multiple IP devices in conference mode. This allows several radios or consoles to connect together in a conference or party-line mode. For further information about the applications of conference mode, refer to Connecting Multiple IPR Devices Using Conference Mode on page Advanced Configuration: IPR110Plus

123 Figure 58. VoIP conference mode settings Various configurations are provided for linking the radios depending on the network and the radio set up. The IPR100 can support up to four devices connected together in a conference mode in addition to the remote device. Other devices that can be connected to a conference include the IPR100, IPR110Plus, DX-Altus/DX64 IPE, the DX64CC and DX64CSD consoles. Important Conference mode affects audio, DTMF, SELCALL, and CTCSS (sub-audible) tones. The Conference Mode configuration includes the following settings: Enable Conferencing enables the conferencing mode. The default value is disabled. Conference Mode selects the type of conference mode (see Table 12); and it determines if the audio is linked or retransmitted to the other devices in the conference. The default setting is Peer to peer: No central server. Important Conference mode does not affect serial pass-through mode. Enable associates the IP address and port configuration for conferencemode transmissions. The default value is disabled. IP Address is the IPv4 address for this conference (i.e., the IPv4 address of the remote IPR device). As for the VoIP remote address, this can be a numeric (dot-decimal notation) IPv4 address or a domain name. Allowed values are a valid remote VoIP address. The default is to Transmit Port is the IP port number that is used for transmitting audio and control messages. As for the VoIP Transmit Port, two consecutive ports are used: the first port is for the actual audio data, and the second port is for control and status information. Allowed value is an even number from 1026 to The default port is IPR100/IPR110Plus Product Manual 107

124 Chapter 5 In conference mode, several radios or consoles can be connected together in a conference so that when any radio or console in the conference receives audio, it is transmitted to all, or some of the other devices, in the conference. Table 12 lists the available conference modes. For further information about conference mode configurations, refer to Connecting Multiple IPR Devices Using Conference Mode on page 189. Table 12. VoIP Conference Modes Mode Peer to Peer: No Central Server Bridge Server: Audio Linked Dispatch Server: Audio not Linked Gateway: Audio Linked Description All IPR devices communicate with all the other IPR devices (see Peer-to-Peer (No Central Server) on page 190). All IPR devices communicate with this IPR110Plus which forwards the audio to all remote devices (see Bridge Server on page 196). All IPR devices communicate with this IPR110Plus. This IPR device does not forward any of the remote audio (see Dispatch Server on page 199). IPR devices communicate with this IPR110Plus that is connected to a gateway router or server. This IPR device forwards audio to/from the remote connection (see Multicast Gateway on page 202). Advanced SIP Settings Session Initiation Protocol (SIP) is used to create connections to a VoIP device. The IPR110Plus supports both inbound and outbound connections to Omnitronics products and third-party SIP devices and servers. Audio from a SIP connection can also be transmitted over a configured VoIP link. Figure 59 shows the configuration page for the SIP settings when you select the SIP menu in the Advanced Mode. SIP Settings The settings available under SIP Settings include the following: SIP Enable enables support for SIP communications. Selecting this option will allow the IPR110Plus to accept incoming connections from other Omnitronics products, such as the IPR100, IPRMon, and IPRDispatch. The default setting is disabled SIP Port is the IP port number used for the SIP connections. The allowed values are 1025 to The default value of 5060 is the port assigned by the Internet standards body for SIP. 108 Advanced Configuration: IPR110Plus

125 Note The SIP Port must match the setting used by the device that will connect to the IPR110Plus; and the value must be different to the port numbers used by the VoIP/RTP configuration. Figure 59. SIP configuration page Default Transport Protocol is the default transport protocol used for transmitting SIP messages. The IPR110Plus supports both the User Datagram Protocol (UDP) and Transmission Control Protocol (TCP). This option is for compatibility with devices and servers that only support one of these transport protocols. Regardless of the value of this setting, the IPR110Plus will correctly respond to SIP messages sent to it using both UDP and TCP transport protocols. Allowed values are: UDP - User Datagram Protocol, TCP - Transmission Control Protocol. The default is: UDP - User Datagram Protocol. IPR100/IPR110Plus Product Manual 109

126 Chapter 5 Note The Default Transport Protocol setting may not appear on the configration page as it depends on the firmware version installed in your IPR110Plus. Only firmware versions 5.13 and later support both the UDP and TCP transport protocols, whereas, firmware versions older than this only support the UDP transport protocol. This setting does not appear for the older firmware. User Name is the name that can be used to validate an incoming SIP connection; and it can also be used as a user name to log into a SIP registrar. If an incoming SIP connection does not have the correct user name, it will be rejected. When a SIP server is used, the user name is used to authenticate the IPR110Plus. Allowed value is a string without any spaces or punctuation characters. The default is ipr. SIP Server Enable allows the IPR110Plus to register with a SIP server. This is required if the IPR110Plus is interfacing with a phone system. If the IPR110Plus is connecting directly to another Omnitronics product, a SIP server is not required. The default is disabled. Note When using a SIP server, the IPR110Plus may need to use a DNS server. If the IPR110Plus is using DHCP, the DNS server will be automatically configured. If the IPR110Plus has a static IP address, the DNS value will need to be configured (see Configuring the Advanced Network Settings on page 92). SIP Registrar Server is the IP address of the SIP server with which the IPR device will register. This can be a numeric IP address (e.g ), a domain name (e.g. somehost.example.com), or a SIP URI (e.g. myhost.example.com, see SIP URI on page 225). The default is blank. SIP Outgoing Proxy is the address of the server used to handle SIP registration. Some SIP service providers use a separate server for handling registration and making calls. The SIP service provider will provide the address details for your configuration. This can be either a numeric address or a fully-qualified domain name. SIP services generally work with DNS name resolution, so this address is most likely to be a fully-qualified domain name of the form host.org or host.net.au. The default is blank. SIP Server Password is the password that the IPR110Plus uses to register with the SIP server. Allowed value is a text string without any spaces. The default is blank. SIP Realm is a string to be displayed to users so they know which username and password to use, and is part of the authentication process. This should contain at least the name of the host performing the authentication, and may additionally indicate the collection of users who might have access. An example might be registeredusers@omnitronics.com.au. 110 Advanced Configuration: IPR110Plus

127 When the IPR110Plus registers with the SIP server, it provides a username, realm, and password. This value is provided by the SIP service provider. Allowed value is a text string without any spaces. The default is blank. Registration Expires is how often the IPR110Plus must re-register with the SIP server. Allowed value is 60 to seconds. Default is 900s. Enable local status sounds option allows the IPR110Plus to play a distinctive sound when a SIP connection is made or disconnected (see Table 13). Push-to-talk is activated automatically during play out. The DTMF/SELCALL lead-in and lead-out delay settings are used to control the Push-to-talk lead-in and lead-out (see DTMF/SELCALL on page 117). This setting is disabled by default. Enable remote status sounds option allows the IPR110Plus to transmit a distinctive sound to the remote sip device when a SIP connection is made or disconnected (see Table 13). If the IPR110Plus disconnects the SIP connection, it will play the disconnect sound, pause to allow the sound to be transmitted, and then disconnect the SIP connection. This setting is disabled by default. Disable changing transmit CODEC type prevents the IPR110Plus from selecting a different codec other than the one that is selected on the VoIP/RTP configuration page. When this option is selected, the IPR110Plus will only transmit audio using the codec configured on the VoIP/RTP page; otherwise, the IPR110Plus may change the codec used to transmit audio when a SIP connection is received. Select this option where the configured codec should not be changed, such as when GSM is selected for the main VoIP link to reduce bandwidth. The IPR110Plus will, however, still accept and decode received RTP audio packets that use a different codec type. Table 13 lists the connection status sounds that the IPR110Plus can play. Table 13.

128 Chapter 5 Voice Activity Detection (VAD) The IPR110Plus is a gateway device between phone systems that do not provide an E&M control interface. To provide a mechanism to control radios that need PTT signal, the IPR110Plus can perform Voice Activity Detection (VAD) on the audio received from the network. The settings under the Voice Activity Detection (for SIP devices) include the following: PTT/Busy Control Mode determines how the IPR110Plus controls the local PTT (or Busy) output. Normal (controlled by remote device) (SIP) Connection Active (VAD) Voice Activity Detection This is the same functionality as provided by an RTP connection: remote busy status or CTCSS keying controls the local PTT/Busy output (this is the default setting). While a SIP connection is active, the local output is active. When the SIP connection is terminated, the output becomes inactive. This could be used with a full-duplex radio When the IPR110Plus determines the remote device is sending voice data, the local PTT/Busy output is activated. If the remote device supports silence suppression (meaning that it will stop sending packets when it detects the operator is not talking), the IPR110Plus will use the presence of packets as part of its VAD algorithm. Fixed threshold for VAD allows you to select a fixed threshold for detecting voice activity instead of using an adaptive threshold. You can select the fixed threshold from the drop-down list for the following parameter to adjust the sensitivity of the network Voice Activity Detection. If this option is deselected, the IPR110Plus will automatically adjust the sensitivity of the VAD. The default setting is disabled. Note The threshold sensivity for VAD only effects the detection of voice for data coming from the network and controlling the local Push-To-Talk output; and it does not effect the VAD algorithm used for audio inpu. Voice detection threshold sensitivity allows you to select a fixed threshold sensitivity for detecting voice activity. You can select one of the following settings: Receive Level Quietest Most sensitive: PTT will be activated with a low voice signal from the remote SIP phone (this is the default setting). Select this option if background is minimal or non-existent. 112 Advanced Configuration: IPR110Plus

129 Receive Level Quiet Receive Level Loud Receive Level Loudest Not as sensitive: PTT activation requires more voice signal from the remote SIP phone. Select this option for low-levels of background noise. Less sensitive: PTT activation requires more voice signal form the remote SIP phone. Select this option if PTT is activated by background noise. Least sensitive: PTT requires high level of audio before PTT is activated. Select this option for environments with high levels of background noise. Connection Control The IPR110Plus can initiate and receive SIP calls. This section determines how a SIP session is controlled. Connection Control determines how SIP connections are made, and can be one of the following: Web Interface Tone Sequence (SELCALL/DTMF) and Web Interface Calls can be made by going to the Connection web page (only available in Advanced Mode this is the default setting). Calls can be made by going to the connection web page and by playing a tone sequence into the IPR110Plus audio input. Tone Scheme selects the type of tone sequence used to control the SIP connection. Used if connection control is via tone sequence and it determines the type of tones the IPR110Plus expects. If you are using SELCALL, all tone sequences must be the configured SELCALL sequence length. The setting can be one of the following: SIP Tone Control: SELCALL SIP Tone Control: DTMF Uses SELCALL for SIP control (default). Uses DTMF for SIP control. Connect all sequence is the tone sequence to use when detecting a connect-all tone sequence. When the IPR110Plus detects this sequence, it will connect all configured remote SIP devices. You can specify a DTMF or SELCALL sequence. If using SELCALL, this sequence must contain the number of non-space tones configured. This setting defaults to blank. Disconnect all sequence is the tone sequence to use when detecting the disconnect-all sequence. When the IPR110Plus detects this sequence, it will disconnect all remote SIP devices. This disconnects any device that called the IPR110Plus even if it is not in the remote device list. You can specify a DTMF or SELCALL sequence. If using SELCALL, this sequence must contain the number of non-space tones configured. This setting defaults to blank. IPR100/IPR110Plus Product Manual 113

130 Chapter 5 Remote Device List Figure 60 shows the Remote Device List area of the SIP configuration page. You can use this list to specify the details for connecting and disconnecting remote IP devices using SIP. Figure 60. SIP remote device list You can specify up to 12 remote devices the IPR110Plus can call using SIP. Each item in the remote-device list has the following settings: SIP Address (URL) specifies the address of the remote device. A SIP endpoint has an identifier or Universal Resource Locator (URL) that is similar to a web address. The SIP URL is usually of the form sip:user@address:port, where user is the user name, address is the IP address of the device, and port is the UDP port used for SIP. It is not necessary to add sip: to the address in the IPR110Plus configuration. The port number is optional and will only be required if a port number other than the standard port of 5060 is used. If the address is invalid, the IPR110Plus will not be able to connect to the remote device. The default is value blank. Some example addresses are: sip:ipr@ ipr@ipr110plus- 52A1212.local fred@sipserver.org @telco.com Local network statically configured to IP address SIP user name set to default value of ipr. Local network configured to have a dynamic address. Serial number is 52A1212 and it is configured to use mdns local name resolution. SIP user name set to the default value. SIP Phone with user name fred connected via a SIP server named sipserver.org. Phone number via SIP to PSTN provider teleco.com. 114 Advanced Configuration: IPR110Plus

131 Connection to SIP softphone running on a PC with static IP address of and UDP port for SIP connections. Connect is the tone sequence used to connect the SIP device. Allowed value is a valid tone sequence: for DTMF, a string with no spaces and using only the characters 0-9, A, B, C, D, #, and *; and for SELCALL, a sequence of characters that only contains valid SELCALL characters and the configured SELCALL tone sequence length. Default value is blank. Disconnect is the tone sequence used to disconnect the SIP device. Allowed value is a tone sequence: for DTMF, a string with no spaces and using only the characters 0-9, A, B, C, D, #, and *; and for SELCALL, a sequence of characters containing SELCALL characters and the configured SELCALL tone sequence length. Default value is blank.

132 Chapter 5 * The DRG100-P25 can connect directly (without going through a PABX) to the SPA8800 for special radio to phone connectivity available with Relm portable P25 radios and Eclipse P25 base radios. Outgoing analog phone calls can be made in this way, but phone calls cannot be received. The IPE (in TEL mode) can connect with the SPA8800 through a SIP PABX to provide analog phone functionality on DX-Altus (as an alternative to using an LIU connected to a PLI analog phone interface) this configuration supports incoming and outgoing analog phone calls. Tone Signaling Settings Figure 61 shows the configuration page for the Tone Signaling settings when you select Tone Signaling in the Advanced Mode. Figure 61. Tone signaling configuration page This configuration page consists of four individual tab pages of settings: DTMF/SELCALL, EIA Tone Remote, Guard Tone, and MDC1200. The IPR110Plus supports various tone and data signaling schemes by detecting and converting the signaling information from analog to a digital data packet. The data packet is then sent to the remote device that converts the data packet back to the analog source signal. This enables tone- and datasignaling schemes to be used with lossy compression codecs. 116 Advanced Configuration: IPR110Plus

133 The IPR110Plus supports MDC1200 data packets by detecting the modulated data, decoding it, and then sending it to the remote device. This enables MDC1200 to be sent on links with GSM or other compression codecs. It also enables MDC1200 to be converted to and from SELCALL data. The IPR110Plus supports EIA tone remote signaling. This consists of one or two tones of a set frequency sent at the start of a transmission. In some radios, these tones are used to change channels or to control radio functions. The IPR110Plus supports guard tone and in-band tones. An in-band tone can be used to control radio transmitting and keying or can also be used to activate particular radio functions. To prevent the in-band tone and the audio from interfering with each other, the IPR110Plus includes digital filters and detectors. The IPR110Plus supports both MDC1200 and SELCALL; however, only one can be enabled at a time: that is, enabling either function will disable the other. For example, if you enable MDC1200 or EIA Tone Remote, the SELCALL settings will be disabled and will not appear on the DTMF/SELCALL page, as shown in Figure 62. Figure 62. SELCALL is disabled when MDC1200 or Tone Remote is enabled. DTMF/SELCALL The settings on the DTMF/SELCALL page are grouped under several headings as discussed in the following sections. General The settings on the DTMF/SELCALL page available under the General heading include the following: IPR100/IPR110Plus Product Manual 117

134 Chapter 5 Tone Transmit Level is the output level for transmitting both SELCALL and DTMF tones to locally installed equipment. This level does not affect the audio transmit level and is not affected by the audio transmission level. Allowed values: -10 db to +10 db Default: 0 db Lead In Delay (10 x milliseconds) The IPR110Plus will assert the PTT relay for this length of time before starting to transmit a SELCAL or DTMF tone. This is to ensure the radio is on and transmitting correctly before the tone is transmitted. Allowed values: 2 to 255 (20 milliseconds to 2.55 seconds). Default: 100 ( 1 second) Lead Out Delay (10 x milliseconds) The IPR110Plus will hold the PTT relay on for this time after a DTMF or SELCAL tone. This is to ensure the radio does not turn off before the whole tone has been received. Allowed values: 2 to 255 (20ms to 2550ms). Default: 50 (500ms). DTMF The settings on the DTMF/SELCALL page available under the DTMF heading include the following: DTMF Detection enables the local detection of DTMF tones. If this is selected, the IPR110Plus will locally decode DTMF tones. When it receives a valid DTMF tone, it will encode it as a data packet and send it to the remote IPR110Plus. At the remote IPR110Plus, when the data packet is received, it will generate a corresponding DTMF tone sequence. This feature is enabled by default. DTMF Tone Period (in milliseconds) specifies the tone period and the period of silence used for generating DTMF signals. The allowed values are 100 milliseconds and 50 milliseconds. Some equipment with slow detection periods may require the 100 millisecond option, which is the default setting. SELCALL (Selective Calling) The settings on the DTMF/SELCALL page available under the SELCALL (Selective Calling) heading include the following: SELCALL Enable allows the IPR110Plus to locally detect SELCALL. If this option is selected, the IPR110Plus will locally detect and decode SELCALL tone sequences. When it receives a valid SELCALL sequence, it will encode it as a data packet and send it to the remote IPR110Plus. At the remote IPR110Plus, when the data packet is received, it will generate a SELCALL sequence with the same numbers. The default setting is enabled. SELCALL Scheme specifies the type of SELCALL scheme to be used. The supported SELCALL schemes are: EEA, ZVEI-I, ZVEI-II, ZVEI-III, PZVEI, CCIR, EIA, and DZVEI. The default setting is CCIR. 118 Advanced Configuration: IPR110Plus

135 Number of Tones specifies the number of tones and gaps (silence) in a valid SELCALL sequence. The allowed number of tones is 1 to 20. The default setting is 5. SELCALL Tone Period (milliseconds) is the duration of each tone or gap (silence) in the sequence. The period can range from 20 to 100 milliseconds. The default setting is 20 milliseconds. Tone Position and Type The settings on the DTMF/SELCALL page available under the Tone Position and Tone Type headings include the following: Tone Position and Type shows the position of each configured tone and the how the tone is configured: the IPR110Plus can be configured to detect a particular tone or silence duration. The possible values are: Tone: Normal Period Tone: Extended Period Specifies a tone that is equal in duration to the period of the configured tone. Specifies a tone that is twice the duration of the period of the configured tone. Silence: Normal Period Specifies a period of silence that is equal in duration to the period of the configured tone. Silence: Period Extended Specifies a period of silence that is twice the duration of the period of the configured tone. When configuring these settings, several rules are applied to ensure the tone sequence is valid: the first and last tone positions must be configured as a tone, and an extended tone period can only be configured in a position after a silence period. IPR100/IPR110Plus Product Manual 119

136 Chapter 5 Example Selcall Configurations To use the selcall feature, you must first select the SELCALL Enable option, which enables all of the selcall settings, as shown in Figure 63. In this example, the selcall tone scheme is set to CCIR, and five tones are configured each with a period of 20 milliseconds. Figure 63. Example of CCIR selcall configuration In the example shown in Figure 64, the selcall tone scheme is set to EIR with six tones configured each with a tone period set to 40 milliseconds. The first four tones are normal tones with a double-width gap followed by an extended status tone (i.e. a double-width status tone). Figure 64. Example of EIA selcall configuration 120 Advanced Configuration: IPR110Plus

137 In the example shown in Figure 65, the selcall tone scheme is set to CCIR, the tone period is set to 33 milliseconds, and four tones are configured as the source address, with a double-width gap, followed by four tones for the destination address with a gap, and then two status tones. Figure 65. Example of EIA selcall configuration EIA Tone Remote Figure 66 shows the Tone Remote section. A tone remote, also known as an EIA tone remote, is a signaling system used to operate a two-way radio base station by remote control. A tone remote (i.e. a sequence of two tones) can be used to control certain radio functions, such as keying up the transmitter or changing channels. Figure 66. Channel change to tone remote conversion IPR100/IPR110Plus Product Manual 121

138 Chapter 5 Tone remotes send commands to a remote radio base station using function tones, a sequence of two tones. Typically EIA tone remotes consist of a highlevel tone followed by a low-level tone. A continuous low-level tone follows. Voice is multiplexed over the tone. The low-level continuous tone is often called the low-level guard tone. The low-level tone is present at the same time as transmitted voice, and is the same tone as the high-level tone. A notch filter eliminates the low-level tone from the transmit audio. The Tone Remote section includes the following settings: Tone Remote Enable enables the transmission and detection of tone remote frequencies as data packets. If this option is not set, tone remote frequencies will be transmitted as normal audio. This function is disabled by default. Number of Tones specifies the number of control tones to detect or transmit. This number does not include the high-level tone (if used). The high-level tone is enabled on the Guard Tone page. Allowed values: 1 or 2. The default is 1. Transmit Level is the transmit level for the generated tone remote. Allowed values: 0 to -20dBm. Default level is -20dBm. Tone duration is the duration (in milliseconds) of the transmitted tone remote information. If the number of tones is set to two, both tones are the same duration. Allowed values: 40 to 255ms. Default is 100ms. Detect tones at start of transmission only ensures that tone remotes are detected only at the start of a transmission. This is based on local radio busy and detection of the guard tone. The value prevents the IPR110Plus from incorrectly detecting tones in normal speech. This function is selected by default. Channel change enable is a compatibility option for Omnitronics 960 consoles and Omnitronics DX64 dispatch systems that support channel change. When this option is selected, the IPR110Plus will convert DTMF messages into a tone remote sequence. Typically a 960CSD will send a channel-change request as a DTMF string with the format *CCCC#, where CCCC is the channel number. When this option is selected and the IPR110Plus receives a DTMF data packet, it will convert it into either a one- or two-tone remote. This feature is selected by default. Enable frequency detection selects the frequencies to be used in the detection of tone remotes. To prevent false decodes, frequencies that are not required can be disabled. 122 Advanced Configuration: IPR110Plus

139 Channel Change to Tone Remote Conversion For an IPR110Plus with only a single tone remote configured, the channel number is from 1 to 16 and specifies the frequency as per the channelfrequency table shown in Figure 66. For example, if the channel number 14 is selected on an Omnitronics console, the DTMF sequence of *15# will be sent, and this will be translated into F14, which according to the frequency detection table, is 1850Hz. For an IPR110Plus with two tones configured as a tone remote, the channel number ranges from 1 to 256, and the tones are determined as follows: the first tone is the channel-change number modulus 16 and the second tone is the channel-change number divided by 16. For example, if the channelchange number 33 is selected on the Omnitronics console, the DTMF sequence *33# will be sent; and this will be translated into the first tone F1 550Hz (i.e. 33 modulus 16 = 1), and the second tone is F2 650Hz (i.e. 33 divided by 16 = 2) Guard Tone A Guard Tone or in-band tone is mixed with the audio and can be used to control radio transmission. The tone remote functions are generally used with a guard tone, however, it is possible to use a guard tone without enabling the tone remote functionality. Figure 67 shows the Guard Tone page. Figure 67. Guard tone configuration The settings available under the Guard Tone heading include the following: Guard tone enable enables the guard-tone detection and generation feature. The default is enabled. IPR100/IPR110Plus Product Manual 123

140 Chapter 5 Frequency specifies the frequency of the guard tone. Allowed values: 2100, 2175, 2325, 2500, 2600, and 2970Hz. The default frequency is 2175Hz. Generate guard tone while Push To Talk output active provides an interface to a radio that uses guard tone to control radio keying from a device, console or dispatch system that does not natively support in-band radio keying. When the push-to-talk is activated, the IPR110Plus will generate a guard tone. If the high-level tone is enabled, it will be generated at the start of the transmission. The feature is not selected by default. Half Duplex Mode enables the half-duplex mode of operation. Many systems use guard tones over a two-wire interface to control keying. To interface such systems to an IPR110Plus, a two-wire to four-wire converter may be required. Due to impedance mismatches in the converter, audio transmitted to the converter can be partly reflected. This can lead to false detection of an incoming tone whilst the IPR110Plus is transmitting a tone. If the Half Duplex Mode is enabled, any received tone is ignored whilst the IPR110Plus is transmitting either a guard tone or a tone remote tone. This feature is disabled by default. Low transmit level The transmission level for the low level tone that is mixed with normal audio. It is possible to disable the low level transmit tone completely, this can be used in a scenario where you wish to detect the guard tone and then filter the tone out. Allowed values: Disabled, -10 dbm, -12 dbm, -15 dbm, -18 dbm, -20 dbm, -25 dbm and -30 dbm. Default: -30 dbm Low-level tone hold time In situations with very low levels for the guard tone or bad signal to noise ratios, the tone detection may be intermittent. In this case the Low level tone hold time may be used to filter out transient losses of guard tone signal. Allowed values: 190 to milliseconds. Default: 2000 milliseconds Enable high-level tone This enables transmitting a higher level tone at the start of the transmission burst. If tone remote functions are transmitted, this high level tone is sent before the tone remote tones. Default: Unchecked High transmit level The transmission level for the high level tone Allowed values: 0 dbm to -20 dbmdefault: -20 dbm High-level tone duration Duration of the high level guard tone pulse in millisecond. Allowed values: 40 to 1000 milliseconds. Default: 100 milliseconds. 124 Advanced Configuration: IPR110Plus

141 MDC1200 MDC signaling is a 1200 baud audio frequency signaling scheme. Short packets of data are encoded using a Minimum Shift Keying (MSK) modulation, each packet consists of a 16-bit command type and a 16-bit unit identifier. The IPR110Plus can both decode and encode these data packets. The MDC1200 configuration values are accessed via the Tone Signaling menu option, as shown in Figure 68. Figure 68. MDC1200 configuration Selecting the MDC1200 tab displays the MDC1200 options: Enable MDC1200 enables the MDC1200 detection and generation feature (disabled by default). MDC1200 transmit level specifies the gain that is applied to the MDC1200 packet. Allowed values: +10dB to -10dB. The default is 0dB gain. Activate Push to Talk Output forces the IPR110Plus to assert the local PTT output when sending MDC1200 data. The lead-in and lead-out times configured on the DTMF/Selcall configuration tab will be used. This value has no effect if the MDC1200 to SELCALL Tone Translation mode is enabled (see MDC1200 to SELCALL Translation on page 127). This setting is disabled by default. Enable Analog P25 Mode enables the analog P25 mode, and after the configuration is saved, displays the tab for the Analog P25/MDC1200 page as shown in Figure 69. The settings on this page are specific to the IPR110Plus in a DX system that is interfaced to P25 radio systems using the legacy analog interface. The P25 system sends and receives information using the MDC1200 message protocol. The IPR110Plus translates these messages into messages that are proprietary to the DX64 system. IPR100/IPR110Plus Product Manual 125

142 Chapter 5 Figure 69. Enabling the analog P25/MDC1200 configuration page Analog P25/MDC1200 The Analog P25/MDC1200 configuration page is shown in Figure 69 and includes the following settings: Emergency Mode The settings under Emergency Mode on the Analog P25/MDC1200 page include the following: Emergency mode enable enables the emergency mode and the command used to activate emergency mode. Received command to activate emergency mode specifies the MDC1200 command that is used to activate emergency mode. When the IPR110Plus receives this command, it will activate emergency mode. In this mode, the IPR110Plus operates as follows: a) Terminates any active SIP connections and ignores subsequent SIP connections. 126 Advanced Configuration: IPR110Plus

143 b) Terminates any active P25 Individual Call that is in progress and ignores subsequent Individual Calls. c) Reports the emergency status to the DX system via the IPE. Individual Call Mode The settings under Individual Call Mode allow a DX64 operator, or caller from a SIP phone or PBX, to call a specific mobile without all P25 mobiles participating in the call. Once this mode is enabled, the IPR110Plus will send an MDC1200 command before activating PTT. Individual call mode enable enables the Individual Call Mode and enables all of the settings specific to this mode. Individual call mode command specifies the MDC1200 command that is sent at the start of each PTT transmission. Individual call mode timeout is the timeout period (in seconds) used in individual call mode. If PTT activity is not detected within this timeout, the individual call mode will be automatically terminated. Individual Call DTMF to Radio Conversion enables SIP callers to place an Individual Call. To make an individual call, the caller must enter the following DTMF digits: *NNNN# where NNNN is the four-digit radio number. For example, to call radio ID 0199, the user could enter either *0199# or *199#. Note For this function to work correctly, the SIP phone must support DTMF using the format described in RFC2833. Many phones do not use this format and must be configured accordingly. MDC1200 to SELCALL Translation MDC1200 to SELCALL Translation includes the following setting: Enable MDC1200 to SELCALL Tone Translation enables the MDC1200 tone translation feature. This converts MDC1200 tones into a format compatible with Omnitronics systems that use SELCALL tones. This function is required if the IPR110Plus is used with Omnitronics dispatch systems such as the DX-Altus/DX64, 950, or IPRDispatch. This MDC1200 tone translation section also includes two translation tables that are enabled when you select the Enable MDC1200 to SELCALL Tone Translation setting: MDC1200 Translation to Transmitted Tone is a table for MDC1200 data that is received locally: it is used to create the message that is sent to the remote device via the network. IPR100/IPR110Plus Product Manual 127

144 Chapter 5 Received Tone to MDC1200 Translation is a table used to convert messages received via the network into a local MDC1200 message that is sent to the local radio or device. An MDC1200 message consists for two fields: a four-digit Command ID that determines the type of message sent, and a four-digit Unit ID that determines the source or destination of a particular message. MDC1200 Translation to Transmitted Tone Figure 70 shows the MDC1200 Translation to Transmitted Tone section. Figure 70. Translation of received MDC1200 command to transmitted tone Each row in the table includes the following settings: Received MDC1200 Command MDC1200 Command type. Allowed values: Various MDC1200 Commands. Default: (0000) Not Used Received MDC1200 Unit ID When set to Unit ID, the Received MDC1200 Unit ID is used in the current message translation or discarded. When set to Unit ID (*Saved), the Received MDC1200 Unit ID is saved and it can be used in the next transmitted MDC1200 message. This is useful in systems where an ack-nowledgement needs to be sent the radio that initiated a particular function. 128 Advanced Configuration: IPR110Plus

145 Transmitted Tone Leading Leading digits added to the start of the transmitted tone sequence. Allowed values: A string 0 to 8 digits Default: blank Transmitted Tone Trailing Trailing digits appended to the end of the transmitted tone sequence. Allowed values: A string 0 to 8 digits. Default: blank When a valid MDC1200 data packet is received from the local device or radio, and the command type matches the command type specified in a row of the table, a tone sequence is built by adding the leading and trailing digits to the message unit id. Received Tone to MDC1200 Translation Figure 71 shows the Received Tone to MDC1200 Translation section. Figure 71. Translation of received tone to transmitted MDC1200 command Each row in the table includes the following settings: Received Tone Leading specifies the leading digits to match with received tone sequence. Allowed values: a string of 0 to 8 digits. Default is blank. IPR100/IPR110Plus Product Manual 129

146 Chapter 5 Received Tone Unit ID specifies the MDC1200 unit identity when set to Unit ID. The corresponding four digits from the selcall tone sequence are used to determine the MDC1200 Unit ID. When set to BLANK, no tones are expected, and the entire selcall should be listed in the Leading text box. Received Tone Trailing specifies the trailing digits to match with the received tone sequence. Allowed values: a string of 0 to 8 digits. Default is blank. Transmitted MDC1200 Command is the MDC1200 command to which the received tone sequence is translated. Allowed values: various MDC1200 commands listed in the dropdown list. Default is (0000) Not Used. Transmitted MDC1200 Unit ID specifies the MDC1200 Unit ID that is sent when set to Selcall Unit ID. The four digits from the received selcall are used to determine the MDC1200 Unit ID. When set to Saved Unit ID, the last received MDC1200 message is used to determine the MDC1200 Unit ID. Transmitted MDC1200 Push to Talk determines if push-to-talk is active while transmitting an MDC1200 command. Some radios will only accept certain commands while push-to-talk is in the correct state. The lead-in and lead-out times from the DTMF/SELCALL page are used for the controlling the timing of the push-to-talk output pulse. Allowed values: various MDC1200 commands listed in the dropdown list. Default setting is (0000) Not Used. When a tone sequence is received from the network, the MDC1200 function will scan this table until if finds a match where the leading sequence (if not blank) and the trailing sequence (if not blank) are the same as the received tone sequence. When a match is found, the four digits between the leading and trailing sequences are interpreted as the unit ID. An MDC1200 signaling sequence is created using the command type from the row in the table and the calculated unit identifier. 130 Advanced Configuration: IPR110Plus

147 Paging Tones The Paging Tones configuration page under Advanced Mode is shown in Figure 72. To enable the paging functionality, select the Paging tone enable option, and then configure the settings as required. Once you have configured the settings, you must save the settings by clicking Save. Figure 72. Configuration of paging tones Paging scheme is the scheme to use for paging this defaults to Motorola Quick Call 2 (QC2) and cannot be changed. Transmit level is the audio level of the transmit tones and ranges from 0dBm to -20dBm with the default set to -10dBm. Pause duration is the time (in milliseconds) to pause after sending tone 1 before sending tone 2 and ranges from 0 to 200ms with default set to 0ms. Tone 1 duration is the time (in milliseconds) to transmit tone 1 and ranges from 990ms to 1100ms with the default set to 1000ms. Tone 2 duration is the time (in milliseconds) to transmit tone 2 and ranges from 2800ms to 3200ms with the default set to 3000ms. For further details about paging, refer to the DX-Altus Basic Paging Supplement (document number MNL-00136). IPR100/IPR110Plus Product Manual 131

148 Chapter 5 The following information provides details about the radio-paging implementation in the IPR110Plus product. Supports only the Motorola Quick Call 2 paging scheme. Configuration of the Basic Paging feature includes the following parameters: Tone scheme (Motorola QuickCall 2 only), Tone duration, PTT lead-in, PTT lead-out, Tone output level. IPR110Plus does not provide feedback when transmission of the paging tone has completed. Paging tones cannot be used with Selcall, MDC1200, or EIA tones. Paging functionality is transmit-only no detection is used. The same IP message (from SCU) as used for Selcall is used to control paging on the IPR110Plus there will be no confusion as to whether Selcall or paging tones are to be played out as the IPR110Plus will allow only one at a time to be configured. The SCU will send the paging number entered by the user to the IPR110Plus, which will then generate the correct tones based on the paging scheme. Status display will show the last transmitted paging tone sequence. 132 Advanced Configuration: IPR110Plus

149 CTCSS Settings Figure 73 shows the configuration page for the CTCSS settings when you select CTCSS in the Advanced Mode. Figure 73. CTCSS configuration page Tone Detection The settings available under Tone Detection include the following: Enable Tone Detection/Transmission option allows the IPR110Plus to detect and transmit CTCSS tones to the Network as data packets. The IPR110Plus voice circuitry includes a band-pass filter so that CTCSS tones will not be sent as audio data. This option is disabled by default. Tone Detection Validation Time is the period (in milliseconds) during which a frequency must be present before it is considered to be a valid tone. Longer periods make CTCSS tone detection more reliable but will increase the propagation delays of CTCSS information. The allowed values are 10 to 1000 milliseconds. The default is 150 milliseconds. IPR100/IPR110Plus Product Manual 133

150 Chapter 5 Enable audio high-pass filter (300 Hz) enables a high-pass filter that removes the CTCSS tones from the audio path. The default setting is disabled (i.e. high-pass audio filter disabled). Local Keying and Tone Transmission The configuration settings available under Local Keying and Tone Transmission include the following: Transmit Level is the output level (attenuation) applied to the locally generated CTCSS tone. It is independent of transmit audio and transmit SELCALL/DTMF levels. Allowed values: -18dB to 0dB. The default setting is 0db (i.e. no attenuation). CTCSS Lockout Time is the timeout period (in milliseconds) used in fast keying mode and normal keying mode. While the remote PTT/Busy signal is detected, if a remote CTCSS is not detected within this period, the local PTT/Busy signal will not be activated. Generate CTCSS while Push To Talk output active ensures that the IPR110Plus will automatically generate and mix a CTCSS signal to the local audio output. This enables systems that do not support CTCSS to be interfaced with radios that require a CTCSS signal to transmit. CTCSS Push To Talk Frequency is the CTCSS frequency to generate while local push-to-talk output is active. Enabled Frequencies The CTCSS frequencies that the IPR110Plus can detect and generate (in Hertz) appear under Enabled Frequencies as in Figure 74. Figure 74. List of enabled frequencies These frequencies are in Hertz (Hz). The IPR110Plus can detect up to fifteen CTCSS frequencies simultaneously and generate one at a time. 134 Advanced Configuration: IPR110Plus

151 Note To enable a frequency, select the check box next to the frequency. If you attempt to enable more than fifteen frequencies, a warning message is displayed. For a CTCSS tone to be correctly detected and transmitted, that frequency must be enabled on both IPR110Plus and the remote IPR devices. Serial Mode Settings Select the Serial Modes menu in Advanced Mode to access the settings on the Serial Modes configuration page as shown in Figure 75. This page contains the settings for configuring the RS232 serial port (DCE) on the rear panel of the IPR110Plus. Figure 75. Serial Modes configuration showing the Serial Pass-Through settings IPR100/IPR110Plus Product Manual 135

152 Chapter 5 The serial port is capable of supporting three modes of operation: Serial Pass- Through mode, Channel-Change Control mode, and Serial Monitor mode; however, only one of these modes can be in use at one time. Serial Pass-Through Mode providesa transparent link that can be used to connect RS232 devices over the Internet. Support for multi-drop serial communications is provided for seven additional remote destination addresses. All serial and flow control data is sent to all the remote addresses. Serial Channel-Change Mode allows the IPR110Plus to control the channel-change functionality on compatible radios connected via the RS232 serial port (DCE) on the rear panel (see Channel Change Mode on page 138). Serial Monitor Mode is not intended for normal use, but is intended only for technicians or Omnitronics support engineers to assist in initial configuration, diagnosing problems, and troubleshooting (see Chapter 7, Serial Monitor ). Serial Data Pass-Through mode and Radio Channel-Change Control mode are configurable modes, and both are available as tabs on the Serial Modes configuration page. The Serial Pass-Through mode is discussed in the following section. Serial Data Pass-Through Mode The IPR110Plus provides the ability to transmit and receive RS232 data between a pair of IPR devices. This uses a UDP connection between the two units to tunnel RS232 data over the network. Enabling the Serial Pass- Through mode disables the Channel-Change Control mode and the Serial Monitor mode on the serial port. The serial data pass-through function of the IPR110Plus is compatible with both the IPR100 and IPR400. Support for multi-drop serial communications is provided for seven additional remote destination addresses. All serial and flow control data is sent to all the remote addresses. The configuration settings under Serial Pass-Through include the following: Enable Serial Pass-Through selects the serial data pass-through mode and disables the serial monitor mode on the serial port. The default is disabled. Note If Serial Pass-Through mode is enabled, both Serial Channel- Change mode and Serial Monitor mode are disabled. 136 Advanced Configuration: IPR110Plus

153 Remote IP Address is the IP address of the remote IPR110Plus to which the serial data will be sent. Like the remote VoIP address settings, this can be a 32-bit IPv4 address or a domain name. The default is Note The Remote Address does not need to be the same as the VoIP Remote Address, which means that the serial pass-through mode can be used to send serial data to any valid IP address. UDP Port Number specifies the TCP/IP port number that is used for sending the data, which must be set to the same value on both IPR100 devices. The allowed values are 1024 to The default setting is Table 14 lists the compatibility of the serial pass-through mode between the IPR100, IPR110Plus, and the IPR400. Table 14. Compatibility of the Serial Pass-Through Protocol Serial Pass-Through IPR100 IPR110Plus IPR400 (Local/Int l) Protocol (Local/Int l) (Local/Int l) Original 4.14/ i 4.14/ i 3.06/ i New 5.00/ i 5.00/ i 3.07/ i The original serial pass-through protocol existed up to version 4.14/ i of the IPR100 and IPR110Plus firmware and up to version 3.06/ i for the IPR400. The protocol changed to support the multi-drop feature which was implemented in version 5.00/ i of the IPR100 and IPR110Plus and version 3.07/ i for the IPR400. Therefore, the incompatibility to previous versions lies at version 5.00/ i (IPR400) and version 3.07/3/07.02i (IPR400). Version 5.00/ i (IPR110Plus) and version 3.07/3/07.02i (IPR400) are compatible with each other. This change in protocol is hardware independent allowing units in the field to be upgraded to the latest firmware version and therefore support the latest serial protocol. Serial Port Parameters The following settings must match the serial settings of the device connected to the serial port of the IPR110Plus. Baud Rate is the serial data rate in bits per second (bps). The allowed values are: 1200, 2400, 4800, 9600, 19200, and The default is Data Bits specifies the number of bits in the data. The allowed values are 7 or 8. The default is 8. IPR100/IPR110Plus Product Manual 137

154 Chapter 5 Stop Bits specifies the number of bits used to designate the end of the data. The allowed values are 1 or 2. The default is 1. Parity is a basic error-detection scheme. The allowed values are: None, Odd or Even. The default is None. Flow Control specifies the method used to control the flow of data. The allowed values are None, XON/XOFF or RTS/CTS. The default value is None. Inter character timeout (ms) controls how the RS232 data is collected and transmitted over the network. When the IPR device starts receiving data, it will keep collecting data until it gets a time-out or the maximum message length is reached. The allowed values are 1 to 1000 milliseconds. The default is 100 milliseconds. Note If you set the value too long, the communication will be very slow. Maximum Message Length (bytes) is the largest block of data that will be sent over the network in a single packet. The allowed values are 4 to The default is Note If the number of bytes of data exceeds this value, the data will be broken up to several smaller packets. Multi-Drop Mode The configuration settings available under Multi-drop Mode include the following: Enable multi-drop mode enables the ability to send data to multiple remote IPR devices. Multi-drop Address 1 Multi-drop Address 7 are used to specify the address to use for the corresponding multi-drop address. Simply type the multi-drop address you want to use in the appropriate text boxes. Channel Change Mode Select the Serial Modes menu in Advanced Mode, and then click the Channel Change tab to access the settings on the Channel Change configuration page, as shown in Figure Advanced Configuration: IPR110Plus

155 Figure 76. Serial channel-change configuration page This page contains the settings for configuring the RS232 serial port (DCE) on the rear panel of the IPR110Plus to control the channel-change functionality on compatible radios. The serial channel-change mode of the IPR110Plus supports the following transceivers: Codan NGT series Spectra MX800 Simoco SRM9000 Tait TB8100 Base Station/Repeaters (CCI serial protocol) Icom radios supporting the PC Command V2 protocol IPR100/IPR110Plus Product Manual 139

156 Chapter 5 The channel-change mode can be used with the Omnitronics DX64 Operator Console, the Omnitronics IPRDispatch Console, or an Omnitronics 960CSD Console interfaced to an IPR device. The channels are allocated as follows: Channel numbers are available as standard channels Channel numbers are used to report/control scanning and mute forcing on Codan radios only. This is only supported for DX64 Systems at this time (not IPRDispatch). 900 Scanning and Mute are off 901 Scanning On, Mute Off 902 Scanning Off, Mute On 903 Scanning On, Mute On. Channel 999 indicates loss of communications with the radio. Channel numbers are reserved for future use. When a mute-force command is received, in addition to sending the command to the radio, the IPR110Plus will simulate a busy signal from the radio. The serial channel-change feature accommodates radios that ignore serial channel-change request whilst having PTT active (like ICOM radios). Parameters The serial channel-change settings under Parameters include the following: Enable serial radio channel change enables the serial channel-change mode and disables serial pass-through mode for this serial port. The default setting is deselected (i.e. serial channel-change mode disabled). Note If Serial Radio Channel Change mode is enabled, Serial Pass- Through mode and Serial Monitor mode are both are disabled. Radio type is the type of radio that is under the control of the IPR400. The allowed values are Codan NGT, Spectra MX800, Simoco SRM9000, Tait TB8100, and ICOM v2. The default setting is Codan NGT. Serial baud rate is the data transfer rate in bits per second of the serial port. The allowed values are 1200, 2400, 4800, 9600, 19200, and The default setting is Advanced Configuration: IPR110Plus

157 An IPR110Plus with firmware version 5.12 or later configured for serial channel-change has additional settings shown in Figure 77. These settings will not appear for older firmware. Figure 77. Additional settings for newer firmware Additonal settings These settings only available for firmware version 5.12 and later While the PTT disable during serial channel change option is selected, the sequence of events depicted in Figure 78 occurs each time a channel change is requested. Serial Channel Change request NO PTT disable? YES Override PTT to OFF state Send channel-change request to radio Start channel-change lead-out delay Start channel-change lead-in delay Lead-Out Elapsed? NO NO Lead-In Elapsed? YES YES Revoke PTT override Exit Figure 78. Sequence of steps for serial channel-change request Any requests to activate PTT on the associated radio during the above sequence will be ignored. The configurable settings apply to all radio types. IPR100/IPR110Plus Product Manual 141

158 Chapter 5 The additional serial channel-change parameters (for firmware version 5.12 and later) include the following: PTT disable during serial channel change ensures that PTT will remain off for the specified lead-in and lead-out times during a channel change. This option is deselected by default. Channel change lead-in Time is the duration (in milliseconds) which the PTT output remains off prior to sending the serial channel change command. The allowed range is 0 to 5000ms. The default is 100ms. Channel change lead-out Time is the duration (in milliseconds) which the PTT output remains off after sending the serial channel change command. The allowed range is 0 to 5000ms. The default is 100ms. It is recommended that the PTT disable during serial channel change option is selected when ICOM radios are channel-changed from Omnitronics 960 consoles. Channel Configuration The channel-change command may take one of two forms: either a channel number or a channel name. For example, the Codan radio requires a channel name whereas the Spectra 800 requires a channel number. For radio types that require a channel name, the channel configuration table can be used to associate a channel name with a channel number. For radios that do not require a channel name, the channel configuration table is not used. A maximum of 64 channels entries can be configured. Figure 79 shows the settings under Channel Configuration and include the following: Channel is the radio channel number and corresponds to the channelchange number sent by, and reported to, the Omnitronics console. Setting this channel number to zero disables that particular entry in the Channel Configuration table. Allowed channels are 1 to 899 inclusive. The default is 0. Channel Name is the name configured for this channel in the radio. Leaving this field blank means this entry will be ignored. The default is blank. 142 Advanced Configuration: IPR110Plus

181 Chapter 7 Serial Monitor This chapter discusses how to use the built-in Serial Monitor via the RS-232 serial connection on the back of the device to perform basic configuration, and includes the following sections: Overview Serial Communications Setup on page 166 Using Recovery Mode with the Serial Monitor on page 167 Using the Serial Monitor on page 168 Resetting to Factory Default Settings on page 170 Overview The Serial Monitor is intended for technicians or Omnitronics support engineers to assist in diagnosing and troubleshooting problems. You should use the built-in configuration interface to configure the IPR device. Before using the IPR device for the first time, you will need to configure the basic network settings to suit your particular environment. The easiest way to do this is to use the Serial Monitor with serial communications software such as TeraTerm this popular serial communications software is freely downloadable from the Internet. You can use whatever serial communications software you like, however, the following section discusses how to set up TeraTerm to communicate with the Serial Monitor (see Serial Communications Setup on page 166). IPR100/IPR110Plus Product Manual 165

182 Chapter 7 Serial Communications Setup This section describes how to set up TeraTerm for use with the built-in Serial Monitor. The same steps should apply to other serial software. You can use the Serial Monitor to configure the basic network settings of the IPR device to establish network connectivity. You can then login to the configuration interface with your web browser to configure the IPR device. The Serial Monitor uses the RS-232 serial port on the back of the device to communicate with serial communications software, such as TeraTerm. The pin assignments of this connector are shown in Figure 94. Figure 94. RS232 serial connections If your computer does not provide any RS232 serial ports, you can use an RS232-to-USB adapter to connect to the IPR device. The port used for the adapter will appear as a virtual COM port in Windows. To connect to the Serial Monitor 1. Connect the serial cable from your computer to the device. 2. Apply power to the device. 3. Click Start, point to All Programs, point to Accessories, point to Communications, and then click TeraTerm. 4. On the Serial port setup dialog, select the port and then set the values as follows: Baud rate: 19200, Data: 8, Parity: None, Stop: 1 bit, and Flow control: None. 166 Serial Monitor

183 5. Click OK to close the dialog. 6. Press Enter on the keyboard. You should now be connected to the Serial Monitor, and you should see the IPR110PLUS $ command prompt, as shown in the screenshot below. You can now use the Serial Monitor to issue commands to the device, as discussed in the section Using the Serial Monitor on page 168. Note If the command prompt does not appear when you press the Enter Enter key, it is possible that your IPR110Plus has Serial Pass-Through mode (or the Serial Channel-Change mode) enabled. In this case, you can enter the Serial Monitor through the back-door by following the procedure in the next section Using Recovery Mode with the Serial Monitor below. Using Recovery Mode with the Serial Monitor This section discusses recovery mode and how to use it to recover the IPR device when it is not responding in Serial Monitor mode (i.e. the command prompt does not appear when you press the Enter key). This will happen when the Serial Pass-Through mode (or the Serial Channel-Change mode) is enabled preventing you from using the Serial Monitor. Using recovery mode of the IPR device, you can enter the Serial Monitor through the back-door and then use it to configure the basic network settings of the IPR device. The following procedure outlines the steps that you can take to recover the IPR device using TeraTerm (you can use some other serial communications program if you prefer). This procedure assumes that you have connected the IPR110Plus via the RS232 serial port to the computer. To recover the IPR110Plus 1. Remove power to the IPR110Plus. 2. Run TeraTerm if it is not already running. IPR100/IPR110Plus Product Manual 167

184 Chapter 7 3. In the TeraTerm window, while pressing the Ctrl-C keys at the same time, apply power to the IPR110Plus. You should see the IPR110Plus start-up messages followed by the command prompt IPR110PLUS $ similar to below: 168 Serial Monitor You should now be able to use Serial Monitor to issue commands and configure the basic network settings, as discussed in the next section. Using the Serial Monitor The Serial Monitor is used to perform basic configuration and diagnostics of the IPR device. You can set the basic network settings, such as IP address, gateway address, and subnet mask to establish network connectivity with the device. You can also reset the IPR device to factory-default settings (see Resetting to Factory Default Settings on page 170). All of the configuration functions provided by the Serial Monitor are also available via the built-in configuration interface. Using the Serial Monitor, you can issue commands to: Display the current configuration Change the basic network settings Reset to factory-default settings Send a network ping to test the network connectivity Perform diagnostic troubleshooting

185 Before you can use the Serial Monitor, you should set up your serial communications software (see Serial Communications Setup on page 166). You can enter commands at the Serial Monitor command prompt by typing the command name followed by the command argument(s), and ending the command by pressing the Enter key some commands allow you to specify a command argument(s) to provide additional information for the command. The common commands used for basic configuration are listed in Table 15. To see a complete list of the available commands, enter help at the command prompt, as in the following example: IPR110PLUS $ help <Enter> The Serial Monitor provides many commands in addition to those listed in the table. However, the additional commands are intended only for testing these are not intended for initial configuration or for use in a live radio network. Important If you set the IPR device on a different IP network or subnet to the computer used to access it, you may not be able to access the configuration interface due to incompatible network settings. Table 15. Configuration commands in Serial Monitor Command aconfig defaults set ipaddress set dhcp ping reset Description Application Configuration command displays the current application configuration settings. Usage: aconfig <Enter> Resets all configuration values back to factor default settings. Usage: defaults <Enter> Sets the IP address.

Usage: set dhcp 0<Enter> to disable DHCP mode or set dhcp 1<Enter> to enable DHCP mode. Sends a special echo message to another machine on the network to test communications. Usage: ping <new address><enter> Causes the device to reset. Usage: reset<enter> IPR100/IPR110Plus Product Manual 169

186 Chapter 7 Resetting to Factory Default Settings You can use the Serial Monitor to restore the IPR device to its factory-default settings by issuing the defaults command followed by the reset command. Note You might lose network connectivity with the IPR device after restoring factory-default settings. In this case, you can use the Serial Monitor to set the basic network settings to match your network. On revision 3 or later hardware, you can also reset the IPR device to factory default settings using the Reset to Defaults button on the back of the device (see Resetting to Factory Default Settings on page 26) The device is restored to the factory default settings listed in Table 16.

187 Chapter 8 Application Examples This chapter provides several examples of connecting radios to IPR devices in a network, and includes the following sections: Remote Radio Access Using Static IP Addressing (VPN) Remote Radio Access Using Dynamic IP Addressing on page 173 Line Replacement Using VOX on page 175 Communicating with a DX64 Radio Dispatch System on page 177 Radio Dispatch Using SIP Connections on page 178 Connecting Radios via ADSL and the Internet on page 179 Connecting Radios using Multicasting on page 187 Connecting Multiple IPR Devices Using Conference Mode on page 189 IPR110Plus Radio to SIP/PSTN Gateway on page 206 Omnitronics 960 Console to Radio with In-band Keying on page 208 Omnitronics Dispatch Console Interface to P25 Base Station using MDC1200 on page 210 Remote Radio Access Using Static IP Addressing (VPN) The remote radio access allows an operator to control and monitor a remote transceiver across an IP network. Using VoIP technology, the audio for transmit and receive along with the PTT and Busy/COS signals, are transported over the link transparently. SELCALL and DTMF are also transported reliably, regardless of the level of compression. Multiple Omnitronics handsets and consoles can be multi-dropped (at the operator site) to allow shared access to the transceiver by a number of operators. IPR100/IPR110Plus Product Manual 171

188 Chapter 8 Figure 95 shows two IPR100 devcies connected over a VPN to control a remote radio using an Omnitronics Console or Handset. In this example, the devices use static IP addresses. Figure 95. Remote radio access using static addressing over a VPN The IPR device should be configured to match the SELCALL or DTMF tone signaling scheme so that tone signaling is transmitted as data. The diagram above shows a single pair of IPR100s connected over the IP network to control a single radio using an Omnitronics Console or Handset. In this example we will assume the network in this case is a simple LAN using static Internet Addresses. If either or both IPR100's were replaced with an IPR110Plus exactly the same configuration values could still be used Table 17 and Table 18 show the configuration values used at each site (any configuration value not listed is left at the factory default setting).

190 Chapter 8 In this example, we will assume the network is an IP network, such as the Internet, using dynamic IP addresses. This example uses exactly the same hardware as used in the previous example, however, in this case we have a network with a DHCP server available on it. We can, therefore, use dynamic addressing and device names to connect the two IPR100 devices if either or both IPR100 devices were to be replaced with an IPR110Plus, exactly the same configuration values could still be used.

191 The IPR100 should be configured to match the SELCALL or DTMF tone signaling scheme so that tone signaling is transmitted as data. Table 19 and Table 20 on the previous page show the configuration values used at each site. Any configuration value not listed is left at the factory default setting Line Replacement Using VOX The Line Replacement mode allows two audio devices, such as 4-wire audio bearers, to be connected back-to-back over an IP link, as shown in Figure 97. As the communications equipment does not provide a COS output, a VOX function is implemented in the IPR device using the built-in VAD feature. When a voice signal is detected on the radio port, an internal COS signal is transmitted to the remote IPR device. This will also enable the transmission of voice packets over the IP network. Full duplex operation is supported. This example links 4-wire audio bearers via an IP Link. As the communication equipment does not provide a COS output, we need to implement the VOX function in the IPR device. Figure 97.

193 Communicating with a DX64 Radio Dispatch System The IPR device can be used to connect remote transceivers to an Omnitronics DX64 Radio Dispatch System, as depicted in Figure 98. The interface provides audio, SELCALL and DTMF signaling information directly to the dispatch system. Figure 98. Communicating with a DX64 Radio Dispatch System Each IPE in the DX64 sub-rack can support four VoIP channels, which can come from an IPR100, IPR110Plus, or IPR400 devices. In this example, an IPR device is connected to the fourth VoIP channel on the IPE. The IPE uses four pairs of port numbers for VoIP connections starting from 5004/5005 for channel 1 to 5010/5011 for channel 4. Note The odd-numbered ports are used by RTCP and should not be used when configuring RTP.

The 960SIP12 uses the SIP protocol to make the connection, and the network (or IPR device) configuration is performed in the IPR120. Figure 99. Radio dispatch using SIP connections from 960SIP Application Examples

195 The IPR device can accept a total of 12 simultaneous SIP connections. An IPR120 will typically have one of the available twelve SIP channels set aside for each IPR device in the network, but this will depend on the network requirements. You will need to configure the IPR device to enable incoming SIP connections, and to configure the SIP user name. Table 24 lists the configuration of the IPR device to use static IP addressing (i.e. no DHCP server available) in a SIP-based Omnitronics DX64 Radio Dispatch System. Table 24.

The example presented in this section is just one way that you can use to connect two IPR100 devices on a network. Figure 100 shows the network configuration for this example, which consists of two sites A and B. Each site contains an IPR100 device connected to a router in its own intranet; and each IPR100 device has one radio connected to it. IPR100/IPR110Plus Product Manual 179

196 Chapter 8 Figure 100. Connecting IPR400 devices over the internet In this example, the ADSL routers at the radio sites use Network Address Translation (NAT) and Port Forwarding to route data packets from an external (class A) IP address to an internal or local (class C) IP address. For further information about NAT, refer to Appendix A, Network Address Translation (NAT) on page 217. The external IP address of the router is mapped to two internal IP addresses: the IP address of the intranet gateway and the local IP address of the IPR100 device on the network. Table 25 lists the addresses used in this application. Note If you change the IP address and subnet mask of the IPR100, you might not be able to access the configuration interface from your computer. If this occurs, see Chapter 7, Serial Monitor for information about how to change the IP address via the serial port of the IPR100. Table 25. IP Address details of routers and IPR100 devices Site A Site B IPR100: IPR100: Router external IP Address: Router external IP Address: Local LAN Gateway Address: Local LAN Gateway Address: Configuring the Network Site A comprises a small network of computers, operator work stations, and an IPR100 so the router is configured to use Network Address Translation and Port Forwarding to connect the IPR100 and the computers to the Internet. Site B comprises only an IPR100, so the router is configured to use the demilitarized zone (DMZ) to connect the IPR100: in this configuration, the IPR100 is completely accessible from the Internet. 180 Application Examples

197 Router and IPR100 Configuration for Site A The router at site A is configured to use port forwarding, which simply tells the router to which device (computer or IPR100) on the local area network to send the data. This allows the IPR100 at site B to reach ports on the IPR100 connected to the internal IP address (inside the LAN). The IPR100 uses the default port numbers of 5004 for Real Time Protocol (RTP) and port 5005 for Real Time Control Protocol (RTCP). For an RTP channel, two ports are required: the first is for the actual RTP voice data, and the other is used for RTCP control and status information. Hence, the router at site A will be configured to forward all UDP messages on ports 5004 and 5005 to the IP local address of the IPR100 device on the LAN. Table 26 lists the port forwarding required. Table 26. Port forwarding configuration for router at site A Protocol Remote Port External Address Local Port Local Address UDP UDP TCP The web server in the IPR100 uses TCP and port 80, the standard port for web servers. To make it accessible via the router, we need to set up port forwarding. As port 80 is commonly used for web servers, it is likely that this port could get scanned or probed by hackers attempting to locate devices to attack. Itt is a good idea to use some other port to forward the web server. The last configuration item (TCP), forwards TCP port 8080 (remote) to port 80 (local) and makes it possible to access the web server configuration of the IPR100 from the Internet using the URL This is optional, but may be desirable for remote sites. Table 27 lists the configuration parameters for the IPR100 at site A. This configures the IPR100 to exist on the LAN at address Once the router at site A is configured (see your router manual for details), the IPR100 at site A needs to be configured with these settings. These network settings configure the IPR100 on the LAN network at IP address , however, you can use the configuration interface to change the network settings of the IPR100 to suit your environment. The combination of the network mask and gateway means that any IP address that starts with x is a local address and will be sent via a local LAN. Furthermore, any IP address that starts with something other than x is an external address. IPR100/IPR110Plus Product Manual 181

The router will then forward the message to the Internet. However, because the router is using Network Address Translation, it will change the messages so that it looks like it has come from address Router and IPR100 Configuration for Site B The router at site B is configured to forward all messages to the IPR100. This is sometimes described as a DMZ Host or Demilitarized Zone Host in the ADSL router documentation. Table 28 shows the IP address translation for the router at site B. Table 28. IP network address translation for router at site B External Address Local Router Address Local DMZ Host Address This setup is still using Network Address Translation (NAT), so all messages to and from the IPR100 will appear to be going to the router s external IP address. In this configuration, all ports are automatically forwarded, so it will be possible to access the configuration web server over the Internet. Table 29 lists the configuration parameters for the IPR100 at site B. This configures the IPR100 to exist on the LAN at address Once the router at site B is configured (see your router manual for details), the IPR100 at site B needs to be configured with these settings. 182 Application Examples

Connecting via ADSL and the Internet with Dynamic DNS In the previous example, we used static IP addressing for routing over the internet; however, this will only work if the router at each site is assigned a fixed public IP address from the respective ISP. In most cases, internet service providers assign dynamic public IP addresses to subscribers rather than fixed or static IP addresses. This means that the public IP address of the routers will change from time to time as the router is restarted or the ADSL connection is reconnected. This example shows you how to configure the IPR100 to use dynamic DNS to maintain communication even if the router s public IP address changes. With dynamic DNS, you configure the IPR100 devices to refer to each other by their fully qualified domain names this is assigned in the VoIP Remote IP address setting and enable Dynamic DNS with proper configuration on both. Use the information provided in Table 30 and Table 31 as a guide. In the event of a change in public IP address in either device, VoIP communication should be re-established automatically.

203 Connecting Radios using Multicasting The IPR device can be used to connect multiple radio and consoles together into a multicast group: this allows multiple devices at multiple sites to be linked together. When any radio or console in the group receives audio, it is transmitted to the other devices in the group. Multicasting, as depicted in Figure 101, is an IP addressing scheme that provides an efficient one-to-many transmission: a single data packet is routed to multiple destinations; however, the network will only duplicate the packet if it needs to go to two different locations. To use multicasting, all the routers in the network must support multicasting and it must be enabled. If your network does not support multicasting, the conference mode configurations described in the following sections provide an alternative. Figure 101. Multiple connections using multicasting Note Many routers on the Internet and some ADSL/DSL modems do not support multicasting. Audio received at any IPR device in the multicast group is transmitted once and received by all the other IPR devices in the group effectively all the radios/consoles are linked together. If any IPR device fails, only that IPR device is affected. All the devices are configured to use a single multicast address as the remote address for the VoIP link. IPR100/IPR110Plus Product Manual 187

204 Chapter 8 To link two or more IPR devices via multicasting, you need to configure the VoIP Remote Address to be a multicast address. The multicast address that you use will depend on the configuration of your network. Multicast Addressing is a protocol for efficiently sending data to multiple IPR devices at the same time over TCP/IP networks (see Multicast Addressing on page 215 for further details). Note If you are attempting to use multicasting via a WAN or the Internet, all network routers between the IPR devices must support multicasting (multicast addresses may not work over the Internet). Table 32 to Table 35 list the configuration for each IPR100 device. Table 32.

Using conference mode, multiple IPR devices can interconnect over an IP network. Several different configurations of conference mode are available as discussed in the following sections: Peer-to-Peer (No Central Server) Bridge Server Dispatch Server Multicast Gateway IPR100/IPR110Plus Product Manual 189

206 Chapter 8 Peer-to-Peer (No Central Server) The peer-to-peer (no central server) conference mode allows multiple IPR devices to communicate directly with each other in a conference. This type of conference is a simulated multicast mode: each IPR device in the conference is configured to send audio to all the other IPR devices, as depicted in Figure 102. Figure 102. Multiple connections using peer-to-peer conference mode Operation Audio received at any IPR device in the conference group is transmitted to all other IPR devices in the group. Effectively all the radios/consoles are linked together. Failure If any one IPR device fails, only that IPR device is affected. Configuration This type of conference mode is the most difficult to configure since all IPR devices in the conference group need to be configured with the addresses of all the other IPR devices in the group. Using conference mode, we can connect multiple devices together on networks that do not support multicasting. This is more complicated to configure and uses more bandwidth as each IPR100 device needs to send its audio packets multiple times. Table 36 to Table 40 list the configuration for each IPR100 device. 190 Application Examples

212 Chapter 8 Bridge Server The Bridge Server conference mode provides the same functionality as the Peer-to-Peer conference mode in a different configuration. In this approach, depicted in Figure 103, all IPR devices are connected to a single IPR device acting as a bridge server ; any audio sent to the bridge server will be relayed to all connected Omnitronics IP devices. Figure 103. Multiple connections using bridging server (linking) conference mode Operation Audio received at any IPR device in the conference group is output on all other IPR devices in the group. Effectively all the radios/consoles are linked together. The server performs linking through VoIP. Failure If the server fails, all communications within the group will also fail. Configuration This mode is easier to configure than Peer-to-Peer as you only need to configure the IPR device acting as the server in the conference. All client IPR devices can be configured with a single destination (i.e. the server IP address). Table 41 lists the configuration of the central server site IPR100 (E). 196 Application Examples

Dispatch Server The Dispatch Server conference mode depicted in Figure 104 is similar to the Bridging Server configuration with the addition of an Omnitronics 960CSD console connected to the server. Figure 104. Multiple connections using dispatch server (no linking) conference mode This application depicts four IPR devices with radios (not shown) connected to a single operator console. The operator console hears the audio from all the radios. If the operator transmits, all the radios will hear the operator. IPR100/IPR110Plus Product Manual 199

216 Chapter 8 However, the radios are not linked and therefore will not hear audio from any of the other sites. Only the central server site, the IPR100 (E), needs to have conference mode enabled. Operation Audio received at any client IPR device in the conference group is transmitted to the server IPR device. Audio transmitted by the server IPR device is output to all client IPR devices. Failure If the server IPR device fails, the whole group will no longer be able to communicate. Configuration This mode is easier to configure than Peer-to-Peer as you only need to configure the IPR device acting as the server in the conference. All client IPR devices can be configured with a single destination (i.e. the server IP address). This configuration will typically be used when the server is connected to a dispatch console such as the Omnitronics 960CSD. Table 46 lists the configuration of the central server site IPR100 (E).

Typically, this configuration may be used to bridge across the Internet. 202 Application Examples

219 Figure 105. Multiple connections using multicast gateway conference mode Operation Audio received at the gateway IPR devices (C and D) from the respective routers is forwarded to all Omnitronics IPR devices in the multicast conference groups and vice versa.

Configuration This mode is easier to configure as only the server IPR devices (C and D) need to be configured in conference mode. All client IPR devices (A, B, E, and F) can be configured with a single remote multicast address and port.

222 Chapter 8 IPR110Plus Radio to SIP/PSTN Gateway The IPR110Plus provides full support for the Session Initiation Protocol (SIP). This protocol allows the IPR110Plus to connect to SIP enabled devices and phone systems. The IPR110Plus can be connected directly or via a SIP server, however, most software or hardware SIP phones require a SIP server. When connected to a central SIP server, called a registrar, the IPR110Plus is available as a SIP device that can be called by any device or phone that has access to that SIP registrar, as depicted in Figure 106. Figure 106. IPR110Plus with software SIP phone Using either a SIP-enabled PBX or a third-party SIP server with PSTN support, the IPR110Plus depicted in Figure 107 can make and receive calls to the Public Switch Telephone Network (PSTN). Figure 107. IPR110Plus SIP to PSTN gateway 206 Application Examples

223 Incoming Calls When a call is made to the IPR110Plus, the caller contacts the SIP registrar which will remember that the IPR110Plus has registered and the Internet Protocol address of the IPR110Plus. It will forward the call request to the IPR110Plus and the caller will be connected. From this point onward, the IPR110Plus and the caller will send audio data directly, without involving the SIP registrar. Outgoing Calls The IPR110Plus can be set up so that any radio user can connect to a maximum of 12 SIP speed dial numbers. Each number can be assigned a SELCALL or DTMF sequence to connect and disconnect. When a radio user wants to call an external SIP device, that user sends the corresponding tone sequence; and the IPR110Plus communicates with the SIP registrar, which forwards the request on to the called device. From this point onward, the IPR110Plus and the called device will send audio data directly without involving the SIP registrar. Table 55 lists the configuration of the IPR110Plus. Table 55.

Omnitronics 960 Console to Radio with Inband Keying In-band keying is useful with radios/transceivers that do not provide E&M control lines. In this case, an in-band guard tone can be used to detect when the radio is transmitting or receiving. Using a pair of IPR110Plus devices, it is possible to connect an Omnitronics 960CSD console to a radio that uses guard tones to control keying. At the IPR110Plus connected to the Omnitronics 960CSD, the local busy output will be activated when the IPR110Plus (connected to the radio) detects a valid guard tone. The IPR110Plus will use a notch filter to remove the guard tone from the audio sent to the Omnitronics 960CSD console. At the IPR110Plus connected to the radio, a guard tone will be generated whenever the IPR110Plus (connected to the console) detects the Push-to- Talk input is active. Table 56 and Table 57 list the configuration of the both IPR110Plus devices required to achieve the desired operation (for this example, the VoIP settings are not shown). 208 Application Examples

Omnitronics Dispatch Console to P25 Base Station using MDC1200 The Tait TB9100 base-station/repeater provides an analog interface between dispatch consoles and P25 terminal radios. This interface supports the MDC data protocol. It also supports certain tone remote signaling functions. The IPR110Plus forms the interface between the Tait TB9100 basestation/repeater and Omnitronics dispatch consoles This example shows how to set up the IPR110Plus to interface the Tait TB9100 base-station/repeater and Omnitronics consoles that support this 210 Application Examples

227 functionality (DX-Altus, RediTALK, 960SIP, and DX64). The IPR110Plus allows the dispatch console to send SELCALL messages to the P25 radio and to receive ANI (terminal ID) information. It can also change radio channels. In this example, if the dispatch system sends a 5-digit selective call tone sequence, it will get converted into an MDC1200 message. If the leading digit is a '0', the message will get converted to an MDC1200 Call Alert message. The next 4 digits are used to represent the MDC1200 Unit ID. When the radio sends an MDC1200 ANI message (command type 8001), the IPR110Plus converts it into a selective call sequence with a leading zero.

229 Appendix A Technical Reference This appendix provides technical details on the protocols used by the IPR product family, and includes the following sections: IP Addressing via the Internet and Local Area Networks VoIP Functionality on page 221 Simple Network Management Protocol (SNMP) on page 227 IP Addressing via the Internet and Local Area Networks This section provides technical details about the protocols used by the IPR product family and discusses some of the more complicated issues that may occur when using the IPR products in certain configurations. IP Addressing The IPR product family provides full support for IPv4; however, as at the time of publication, it does not support IPv6. Therefore, this section discusses IP addressing with respect to IPv4. All devices connected to the Internet or using IP for communication have an IP address. An IPv4 address consists of 32 bits expressed in a form consisting of four decimal octets separated by periods (dots), called dot-decimal notation. An example of an IPv4 address is The IPv4 address consists of two parts: the network address and the host address. The subnet mask determines what part of the IPv4 address is used to identify the subnet on which a device is located. A valid IPv4 subnet mask consists of 32 bits: a sequence of ones (1) followed by a block of zeros (0), expressed in dot-decimal notation. IPR100/IPR110Plus Product Manual 213

230 Appendix A The sequence of ones (1) designates that part as the network address (subnet) and the block of zeros (0) designates that part as the host identifier. Not all IP addresses are created equal, however, and certain ranges of addresses have specific functions. Some addresses are allocated from the private address space used for private networks while others are allocated for multicasting. Currently, three classes of IP addresses are commonly used: Class A (the largest) is identified by the first octet, which ranges from 1 to 126. Class B is identified by the first two octets, the first of which ranges from 128 to 191. Class C (the smallest) is identified by the first three octets, the first of which ranges from 192 to 223. Table 59 shows the different classes and the range of addresses of an IP Address. Table 59. Classes of IP addresses Class of Address Range of First Octet Network Identity Host Identity Subnet Mask A a b.c.d B a.b c.d C a.b.c d Some first-octet values have special meanings: First octet 127 represents the local computer, regardless of what network it is really in. This is mainly used for local loopback testing. First octet 224 and above are reserved for special purposes such as multicasting. Octets 0 and 255 are not acceptable values in some situations, but 0 can be used as the second and/or third octet (e.g ). Another type of private networking uses the link-local address range (in IPv4, the block x.x, which is also shown as /16, is reserved for this purpose). This address range allows a network device to auto-configure its IP address when Dynamic Host Configuration Protocol (DHCP) services are not available. If a host on an Ethernet network cannot obtain a network address via DHCP, an address from to may be assigned pseudo randomly. The IP address space is controlled by the Internet Assigned Numbers Authority (IANA). 214 Technical Reference

231 Multicast Addressing Multicast addressing or multicasting is a method of implementing efficient oneto-many communications. The originating device sends a single packet and the network infrastructure will deliver the packet to all the devices that are listening to the multicast address. Any device that wishes to receive packets sent to a particular multicast address will need to join the multicast group. The protocol used to manage this process is the Internet Group Management Protocol (IGMP). The actual routing of multicast packets efficiently is complicated and is managed by the routers and switches that form the network infrastructure; this complexity is not visible to the end devices that simply have to join the group. The range of addresses to is reserved for multicast addresses: using any address from within this range will automatically put the IPR device into multicast mode. Note Mulicast addresses in the range of to are reserved and should not be used. IP Addresses in the range of to are multicast addresses, and are used for Internet-wide addressing. Using any address from within this range will automatically put the IPR device into multicast mode. You should use these addresses for communicating over a WAN or over the Internet. Note Multicast addresses in the range to are reserved and should not be used. Multicast Addresses in the range to are used for local addressing and should be used for multicast configurations where all IPR devices are on the same LAN, or are all configured on the same IP subnet. Using multicast addressing, a single data packet is routed to multiple destinations; the network will only duplicate the packet if it needs to go to several different locations. For multicast addressing to work, all the network routers in the network must support multicast addressing and have multicasting enabled in their configurations. If your network does not support multicasting, the conference modes provide an alternate solution (see Chapter 8, Application Examples ). Audio received at any IPR device in the multicast group is transmitted once and received by all the other IPR devices in the group. Effectively all the radios or consoles are linked together. If any one IPR400 device fails, only that IPR device is affected. All the devices are configured to use a single multicast address as the remote address for their VoIP link. IPR100/IPR110Plus Product Manual 215

232 Appendix A Note Many routers on the Internet and some ADSL/DSL modems do not support multicasting. Domain Name System (DNS) When you access a web site or a computer over the Internet, the address of that site or computer is usually expressed as a host name (or domain name), such as These host names are converted into an IP address using a special server known as a Domain Name System (DNS) server. A computer communicates with a DNS server that will then provide the actual numeric IP address that corresponds to the host name. A host name consists of two or more labels; the rightmost label is the top-level domain and will be something like.com or.au. Each label to the left specifies a subdomain of the higher domain to the right. Omnitronics IPR products include the support for sending requests to DNS servers and hence converting host names into numeric IP addresses. Multicast Domain Name System (mdns) The Domain Name System converts hostnames into global IP addresses. For it to work, a host needs an allocated static global IP address and access to a DNS server. On local networks, it is desirable to be able to address a device by name without either of these prerequisites. One technique to accomplish this is to use a protocol based on the Domain Name System that uses multicast messaging to resolve names without any central server. The mdns protocol is similar to the DNS protocol that is used for the Internet name resolution. Unfortunately Microsoft products do not support this protocol, so it is not possible to address IPR products by name from Windows XP or Vista. Devices that use mdns addresses use the special top-level domain of.local. This is a short cut to tell the software to use mdns rather than normal DNS to resolve the Internet Address. Note Devices that use an mdns address can cause difficulties if the network servers in an organisation are configured with an internal domain that uses.local as its identifier. 216 Technical Reference

233 Dynamic Addressing Using a DHCP Server Most networks allocate IP addresses to computers and devices on the network using DHCP (Dynamic Host Configuration Protocol). The network provides a DHCP server that automatically assigns an IP address to each network device. DHCP is also widely used for dial-up and broadband Interconnection. The DHCP assigns the IP address, IP subnet mask and default gateway. DHCP servers generally provide addresses with a lease on a particular address for a certain time. As long as the device is leased, and a particular address is renewed, the address will remain allocated to that device. If the device does not renew the lease, the address may be allocated to some other device or computer. If a device that is configured for DHCP cannot contact a DHCP server on start-up, it will not have a valid IP address. In this case a device can default to using an address in the range Network Address Translation (NAT) The process of Network Address Translation (NAT) involves over-writing the source and destination addresses of IP packets as they pass through an ADSL modem or router. Figure 108 illustrates the concept of NAT. Systems using NAT do so in order to enable multiple hosts on a private network to access the Internet using a single public IP address. As well as over-writing the IP addresses sometimes the IP port number can also be changed; this is sometimes called port forwarding. Figure 108. Using Network Address Translation (NAT) Since there may be multiple computers behind a router that is configured to use NAT or port forwarding, it is necessary to configure the router to know the IP address of the IPR device to which a particular port should be forwarded. IPR100/IPR110Plus Product Manual 217

234 Appendix A So for a VoIP link to work through a router that is performing Network Address Translation, additional configuration is required both at the IPR device and at the router. For an example that shows the type of configuration necessary when using an IPR device via an ADSL router that performs address translation, refer to Connecting Radios via ADSL and the Internet on page 179. SIP Network Address Translation can be even more problematic. Part of the SIP call set up is to negotiate which ports to use for sending the RTP/RTCP data. Because these ports are dynamic it is not possible to set up the router in advance for port forwarding. Many ADSL routers include SIP Application Level Gateways (ALG). An ALG is a software component that runs on the ADSL router that understands a particular protocol and allows that protocol to work despite the firewall and NAT. The SIP ALG will re-write parts of the SIP translation with the correct information and set up the associated port forwarding settings automatically. Dynamic Domain Name System (Dynamic DNS) Dynamic DNS is a system for allowing an internet domain name to be assigned to a non-static public IP address. This makes it possible to remotely establish connections to network devices without the need of tracking their changing public IP addresses. Most internet service providers employ a technique of allocating IP addresses dynamically on demand unless clients desire a fixed IP address. As fixed IP addresses come at a premium, most internet users make do with dynamic IP addressing. Network devices that are hosting services behind routers with dynamically changing IP addresses will thus only be reachable by means of DNS lookup. For this to work, however, it is important that references to IP addresses are kept up to date. The onus of keeping the DNS server(s) up to date rests on either the router or at least one network device behind the router. Implementation The Dynamic DNS feature can be enabled on any IPR device running firmware V3.07 or later. If this feature is enabled, the IPR device will perform all dynamic DNS related operations; and it will be responsible for tracking changes in the public IP address by which the device will be reachable across the internet. As an IPR device will typically reside on the private side of a company's network (behind the public router), it will have a private IP address. In order for an IPR device to connect to a remote IPR device, it will need to know the public IP address of the router at the remote end. 218 Technical Reference

235 Furthermore, if the public IP address of the router changes, the Dynamic DNS feature will update its configured Dynamic DNS server. This involves an HTTP request to associate its fully qualified domain name to the new public IP address. Any subsequent name resolution requests should then resolve to the latest public IP address. The IPR device configuration allows for all remote ends to refer to fully qualified domain names. This applies to the VoIP remote destination, conferenced remote destinations, and serial pass-through remote destination addresses. An additional feature of the Dynamic DNS is to perform periodic name resolution of these destination addresses provided they do not contain a raw IP address. If any of the configured remote devices experience a change in public IP address, the local IPR device will perform the required housekeeping to re-establish the RTP, or the conferenced or pass-through communications. Additionally, any SIP conversation can also benefit by optionally forwarding the public IP address of the device to the remote side during SIP call establishment. Compatibility The Dynamic DNS client is designed to be compatible with the DynDNS API as both DynDNS.com and No-IP adhere to this API standard. Minor modifications were made to the client to accommodate ChangeIP.com. The client may well be compatible with other Dynamic DNS host services if they adhere the DynDNS API but this cannot be confirmed. The best approach will be to try your preferred dynamic DNS host service to see if the IPR device is compatible with it. Configuration Figure 109 on the following page shows the different aspects of the dynamic DNS configuration: (A) DNS Servers At least one DNS server is required. (B) Syslog host address Required to log dynamic DNS activity. (C) Public IP Service Returns public IP address of the requester. (D) Dynamic DNS Host Required to update the dynamic DNS host. The Dynamic DNS feature will not work unless at least one of the DNS server fields (A) points to an actual DNS server that is reachable by the device it affects the ability of the device to perform domain name resolution. A value of indicates that this setting is not in use. Ideally these DNS server fields should point to the IP addresses of the DNS servers provided by your ISP used to access the internet. IPR100/IPR110Plus Product Manual 219

236 Appendix A (A) (B) (C) (D) Figure 109. Dynamic DNS configuration In order to log Dynamic DNS activity, you will need to configure the Syslog host address (B) to point to a network device running a Syslog daemon. Note Syslog does not exclusively log Dynamic DNS activity. The Public IP Service (C) should point to the URL of web services that return the public IP address of the requester. This public IP address should be available as a text string within the response in the IPv4 format as described in IP Address (see IP Addressing on page 213). Examples of public IP servers are: It is best to use a public IP service with a concise text response. Dynamic DNS updates require at least one of these fields to point to an actual public IP service. It is best to have both configured for redundancy. The other Dynamic DNS settings (D) are required by the built-in dynamic DNS update client to keep the Dynamic DNS host informed about changes in the public IP address of the Device Domain Name. If any of these settings is left blank (i.e. not configured), dynamic DNS updates will not occur. Examples of Dynamic DNS Host Update domain names are: DynDNS.com uses members.dyndns.com 220 Technical Reference
