11 Introduction This manual provides information about: Installing and configuring the AFI-IP product Using the AFI-IP product Troubleshooting the AFI-IP product This section includes the following topics: What is the AFI-IP? Features on page 2 Front Panel on page 6 Back Panel on page 9 Firmware Upgrades on page 14 Basic Operation on page 14 Related Documentation on page 15 Documentation Conventions on page 16 What is the AFI-IP? The Omnitronics AFI-IP product is an Audio Facilities Interface (AFI) device designed to operate over IP networks. It provides the audio and control interface for a DX-Altus or DX64 system that allows an operator console, also known as an operator position, to communicate via an IP link such as an Ethernet network. The AFI-IP is fully compatible with both DX-Altus and the older DX64. Each operator position requires an AFI-IP device and a console computer running Omnitronics console software and both must be connected to the same IP network. The type of console software you use depends on whether you have a DX-Altus system or a DX64 system: DX-Altus system uses Omnitronics Alto Dispatch Console software DX64 system uses Omnitronics DX64 Operator Console software The AFI-IP supports two types of connections to a DX-Altus or DX64 system: Static Connection allows the AFI-IP to permanently connect to an IPE device and operator position. The AFI-IP will continue to operate even if the console software is not running. Dynamic Connection allows the AFI-IP to connect to an IPE based on control messages from the console software, and enables an AFI-IP to connect to any operator position and multiple DX-Altus or DX64 systems.

12 The AFI-IP product is available in two types: the standard AFI-IP, which satisfies the majority of system requirements, and the enhanced AFI-IP+ (pronounced AFI IP Plus ). The enhanced version includes an additional wireless headset port accessible on the front panel and several firmware enhancements to support acoustic-shock protection. Note In this manual, the term AFI-IP will be used to mean both the standard AFI-IP product and the enhanced AFI-IP Plus product unless the context requires otherwise. Figure 1 shows the front and rear views of the standard AFI-IP product and Figure 2 shows the front and rear views of the enhanced AFI-IP Plus product. Figure 1. AFI-IP front and rear views Figure 2. AFI-IP Plus front and rear views The front panels provide various LED indicators for status information, several connectors for headsets and handset, including a connector for a wireless headset (AFI-IP Plus provides an additional connector for a second wireless headset), and two toggle switches for PA/Intercom and PTT. The rear panels include power connectors, connectors for data port, Ethernet network, footswitch or desk microphone, 4-wire E&M radio interface, and a USB connector for serial audio data. The AFI-IP is user configurable: it includes a built-in web server that provides a webbased configuration and management interface. You use this interface to configure the AFI-IP settings. 2 Introduction

13 Figure 3 illustrates an example of a DX-Altus system showing the AFI-IP device, which provides the audio and control interface for one operator position. Figure 3. Example of DX-Altus system incorporating the AFI-IP product The AFI-IP device (operator position) interfaces to an IPE device (in OPR mode) one IPE device (in OPR mode) can support two AFI-IP devices (operator positions). Therefore, IPE-1 provides the interface for both Operator Position 1 and Operator Position 2. The IPE device (in LIU mode) emulates four channels of an LIU device. IPE-2 provides the interface for the first four channels of the emulated LIU-3. AFI-IP/AFI-IP Plus Product Manual 3

24 Firmware Upgrades The firmware in the AFI-IP can be easily upgraded with a new version when it becomes available. Omnitronics periodically updates the firmware to resolve issues or to provide additional functionality or enhancements (see Upgrading the Firmware on page 88). Basic Operation This section describes the basic operation of the AFI-IP it does not discuss the operation of the Omnitronics Alto Dispatch Console software (for DX-Altus systems) or Omnitronics DX64 Operator Console software (for DX64 systems). Note For further information about using the console software, please consult the appropriate user manual: Alto Dispatch Operator User Manual or DX64 Operator Console User Manual. The AFI-IP provides the audio and control interface to the DX-Altus (or DX64) system that allows a DX-Altus (or DX64) console operator (operator position) to communicate via an IP link such as an Ethernet LAN. It also provides ports for connecting various types of audio equipment. The following discussion assumes that AFI-IP is connected to the console computer, the console operator has logged into the console, and a connection has been made to a DX-Altus (or DX64) system. Audio from Radio Channels When using a headset, the operator will hear any active radio channel in either the foreground or background for this operator position depending on whether the channel is in the foreground or background. A radio channel becomes active when: it has an active BUSY signal; or it is configured for VOX operation and the DX-Altus system has detected audio on the input. it is a trunk radio and the system has the trunk connection active Audio to Radio Channels When the PTT signal is active, the AFI-IP transmits audio to all of the foreground radio channels that are in the operator s active workgroup. This allows the console operator to talk on the foreground channels. The PTT is active on the AFI-IP when the operator presses the PTT switch on one of the following: the front panel of the AFI-IP; or a connected desk microphone; or 14 Introduction

25 a connected footswitch; or an Omnitronics headset or console. Audio to and from Telephone Channels When a telephone call is in progress, the operator can talk to the remote end without pressing the PTT switch: the phone channels behave similarly to normal telephones. If the operator presses the PTT switch, the operator's voice will be sent to the radios on the foreground channels in the active workgroup instead of the telephone. Rapid Recall Audio If the DX-Altus (or DX64) System is configured to use the Rapid Recall feature, all conversations that occur on a particular AFI-IP Plus will be recorded to external recording equipment. If the operator presses the on-screen play button (on the Rapid Recall control), the recorded conversation will be heard in the operator s headset. Speaker Audio In the standard configuration of the AFI-IP, if both headsets are disconnected, the operator will hear the audio in the speakers as follows (telephone audio will not be redirected to the speakers): Foreground and rapid recall audio will be heard in the left-hand speaker Background audio will be heard in the right-hand speaker Related Documentation In addition to this product manual, the following documents provide related information for your system: DX-Altus Server (Digital Radio Management) Configuration Guide DX-Altus Alto Dispatch Console User Manual DX64 Radio Management System Technical Manual DX64 Configuration and Maintenance Utility (DX64CMU) User Manual The following documents define the relevant VoIP protocols implemented in the AFI- IP, which are all available from the Internet Engineering Task Force (IETF): RFC RTP: A Transport Protocol for Real-Time Applications RFC RTP Profile for Audio and Video Conferences with Minimal Control RFC RTP Payload for DTMF Digits, Telephony Tones and Telephony Signals RFC SIP: Session Initiation Protocol RFC An Offer/Answer Model with the Session Description Protocol (SDP) RFC SDP: Session Description Protocol AFI-IP/AFI-IP Plus Product Manual 15

27 Getting Started This chapter contains information for connecting the AFI-IP to your network and to get it up and running quickly. This chapter includes the following section: Connecting to the Network Connecting to the Network Omnitronics offers a system configuration service at the customer s request to configure the AFI-IP and other DX-Altus system components. If your AFI-IP is preconfigured for your network, you can simply connect it to your network and start using it as is. In this case, you can skip ahead to the section Basic Configuration, which explains how to make changes to the configuration settings. 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 AFI-IP devices. However, if your AFI-IP 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 AFI-IP is to connect it directly to your computer s Ethernet port using a network cable you do not need to use a cross-over cable. The AFI-IP is factory configured with a static IPv4 address of If the IPv4 address of your computer does not have a similar address (i.e., an IPv4 address starting with x), it will not be able to communicate with the AFI-IP. In this case, you will need to change the IPv4 address of your computer temporarily to the same subnet as the AFI-IP. Once your computer and the AFI-IP are both on the same network, the Link LED should illuminate and the Act LED should blink when network activity is detected. You can then login to the AFI-IP s web server and use the configuration interface to configure the network settings of the AFI-IP to match your network. You can then restore the network settings of your computer. The following section provides step-by-step instructions for configuring the basic network settings of the AFI-IP using Windows 8.1 and Windows 10. If you are using Mac OS or the Linux operating systems, see Connecting with Mac OS X or Linux on page 24 the procedure will be similar although the steps will be different depending on the version of Linux. AFI-IP/AFI-IP Plus Product Manual 17

28 Using the Serial Monitor to Configure the Basic Network Settings If you do not know the IP address of the AFI-IP, you can use the Serial Monitor to configure the basic network settings such as the IPv4 address, netmask, and gateway address of the AFI-IP to match your computer network. Once you have configured the basic network settings, you can then log in to the AFI-IP 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 support engineers to help with diagnostics and resolving issues. For further information about how to change the IPv4 address, netmask, and gateway address using the Serial Monitor, refer to Using the Serial Monitor on page 132. Connecting with Windows This section contains information to help you get the AFI-IP up and running quickly using Microsoft Windows 8.1 or Windows 10 operating system. The screenshots are for Windows 8.1; however, the information for Windows 10 will be similar. If the IPv4 address of your computer does not have a compatible address (an IPv4 address starting with x), you will need to change it temporarily before it can connect to the AFI-IP by following the steps below. Note To change the IP address of your computer, you must be logged in with a user account that has administrator privileges. Step 1: Determine the IP address of your computer You can get the address of your computer by following the procedure below. To determine the IP address of your computer 1 On the Start menu, click Control Panel. 18 Getting Started

30 6 Record the details for IPv4 IP Address, IPv4 Subnet Mask, and IPv4 Default Gateway from the Network Connection Details, and then click Close. Step 2: Change the IP settings of your computer Before you can connect to the AFI-IP, you need to temporarily change the IP settings of your computer to match the IP settings of the AFI-IP. If the IPv4 Address of your computer (see Step 1: Determine the IP address of your computer on page 18) starts with the numbers x and the IPv4 Subnet Mask is , your computer is using a compatible IP address and it will be able to communicate with the AFI-IP without any changes to its IP settings. In this case, you can skip to Step 3: Connect the AFI-IP to the computer on page 22. However, if the IPv4 Address of your computer does not start with the numbers x, you will need to temporarily change the IP address of your computer. Important Ensure you record the current IP settings of your computer so that you can restore it to its original configuration after you have completed configuring the AFI-IP device. To configure the IP settings on your computer 1 In the Local Area Connection Status dialog, click Properties to display the Local Area Connection Properties dialog. 20 Getting Started

The changes will take effect immediately; it should not be necessary to restart your computer. AFI-IP/AFI-IP Plus Product Manual 21

32 Step 3: Connect the AFI-IP to the computer This step connects the AFI-IP directly to your computer using an Ethernet cable. To connect the network cable 1 Apply power to the AFI-IP. 2 Connect the network cable from your computer to the Ethernet port on the rear panel of the AFI-IP. The Link indicator will illuminate and you should now be able to communicate with the AFI-IP device; otherwise, you may have a problem with the network cable. Step 4: Configure the AFI-IP network settings This step uses the web-based configuration interface to configure the network settings of the AFI-IP. To configure the AFI-IP network settings 1 Start your web browser and type the default IPv4 address ( ) of the AFI-IP device in the address bar. Note All AFI-IP devices are factory configured with a default IPv4 address of The AFI-IP login page similar to the one shown below is displayed. 2 Click Log in to show the browser s log-in dialog. 3 In the password dialog, type omni for the user name, and type afi (AFI-IP) or afi+ (AFI-IP Plus) for the password.

The AFI-IP should now be on the same network as your system. AFI-IP/AFI-IP Plus Product Manual 23

34 Step 5: Restore the network settings of the computer Once you have configured the network settings of the AFI-IP device, you can restore the network settings of your computer back to the original settings. Note If you did not change the network settings of your computer, you do not need to perform this step. Repeat Step 2: Change the IP settings of your computer on page 20 to restore the network settings of your computer back to its original settings that you recorded in Step 1: Determine the IP address of your computer on page 18. This time, however, you ll change the IPv4 address, IPv4 Subnet mask, and the IPv4 Default gateway to the original settings. Congratulations! You have now configured the AFI-IP to communicate on your network, and you should now be able to connect to the AFI-IP using the original network settings of your computer. Connecting with Mac OS X or Linux For other operating systems, such as Mac OS or Linux, the same basic steps are necessary: that is, temporarily change the computer s IP address to one in the same subnet as the AFI-IP, such as x, then access the AFI-IP web server to configure the network settings, and then save the configuration and restart. 24 Getting Started

35 Basic Configuration This chapter discusses the basic settings of the AFI-IP product that you can configure using the built-in web server and a web browser, and includes the following sections: What is the Configuration Interface? Launching the Configuration Interface on page 26 Discovering the AFI-IP on the Network on page 26 Using the Configuration Interface on page 27 Viewing the System Status on page 34 Configuring the Basic Network Settings on page 38 Changing the Administrator Password on page 40 Backing up and Restoring the Configuration on page 41 AFI/System Settings on page 44 VoIP and RTP Configuration on page 45 Device Configuration on page 47 What is the Configuration Interface? The AFI-IP includes a built-in web server that provides a configuration and management interface called the Configuration Interface. This interface uses standard HTML and should be compatible with most web browsers. The web-based Configuration Interface provides a comprehensive user interface that consists of a series of web pages designed to help you configure the AFI-IP. Using the Configuration Interface, you can access all the status information, configuration parameters, and diagnostic tools in one convenient user interface. The AFI-IP Configuration Interface supports the following web browsers: Internet Explorer 9 11 Mozilla Firefox 3 and later Google Chrome 14 and later Safari 5 and later The Configuration Interface may also be compatible with other browsers not listed above; however, Omnitronics cannot guarantee the compatibility of such browsers. AFI-IP/AFI-IP Plus Product Manual 25

36 Launching the Configuration Interface To launch the Configuration Interface, you must know the IP address of the AFI-IP you want to configure so you can navigate to its web server using your web browser. If you are configuring the AFI-IP for first time, you can use the default IP address and type into the address bar of your web browser. This will load the login page in your web browser. Note If you do not know the IP address of the AFI-IP, you can use the Serial Monitor to view the network settings and change them as required (see Using the Serial Monitor on page 132). You can also use the Network Discovery feature of Microsoft Windows to discover the AFI-IP on your network, as discussed in the following section. Discovering the AFI-IP on the Network The AFI-IP supports the Universal Plug and Play (UPnP) technology, which allows you to find the device on your network so you can access its built-in Configuration Interface. If the AFI-IP and your computer are connected to your computer network, and UPnP (Universal Plug-n-Play) is enabled in the AFI-IP, you should be able to discover the AFI-IP on your network. You will see all of the computers and devices that are currently part of the network in the Network folder or under the My Network Places depending on the version of Microsoft Windows operating system running on your computer. The AFI-IP product should appear under the Other Devices category with a device name of AFI-IP (e.g. AFI-IP, Name: AFI-IP-Andrews-AFI-IP, V ). The AFI-IP Plus product appears with a device name of AFI-IP Plus. Figure 8 shows how the Network folder might appear under Windows 10. Figure 8. Network discovery of the AFI-IP using Windows Basic Configuration

37 Once you have located the device in the Network folder, double-click it to automatically launch the Configuration Interface and load the login page in your web browser. You can now log in and use the Configuration Interface as discussed in the following section. Note To discover the AFI-IP on your network, the network settings of the AFI-IP must match those of the computer used to access the AFI-IP. That is, the IP address of the AFI-IP must be on the same sub-net as the IP address of the computer. Using the Configuration Interface All configuration and management of the AFI-IP is done using the built-in web server, known as the Configuration Interface. You must log in to the Configuration Interface with a user name and a password before you can view or change any of the configuration settings. This section discusses how to use the Configuration Interface to configure the settings of the AFI-IP. Note All screenshots of web pages shown in the following sections are based on the AFI-IP product unless otherwise stated. However, the web pages for the AFI-IP Plus product will be similar. Figure 9 shows the Network Configuration page that is displayed when you select the Network menu (see Configuring the Basic Network Settings on page 38). Configuration page Displays the name of the configuration page Settings Displays the settings for the configuration page Menu system Basic and Advanced menus Configuration status Status of the configuration settings Figure 9. Network Configuration page showing the Configuration Status area AFI-IP/AFI-IP Plus Product Manual 27

38 At the bottom of this page is the Configuration Status section, which appears on all pages that have configuration settings that you can change. Note Depending on the version of web browser you are using, the Configuration Status buttons may not be visible at the bottom of the browser window. This may happen with some older browsers, in which case, you can scroll to the bottom of the page to view the buttons. The left-hand side of the configuration interface provides the menu system of all the available configuration pages. Selecting a menu item displays the corresponding configuration page on the right-hand side of the interface. The configuration status shows status of the configuration (see Configuration Status on page 33). Each menu is described in the following sections. The configuration provides two modes of operation: Basic Mode provides access to basic configuration settings that allow you to configure a AFI-IP device with minimal settings to get it up and running quickly. Advanced Mode provides access to advanced configuration settings that allow you to configure all aspects of the AFI-IP device. The first item in the menu is the Go to ADVANCED mode item. Clicking on this item changes the Configuration Interface into Advanced Mode. In Advanced Mode, additional menu items and configuration pages are available. The first menu item is Go to BASIC mode, which reverts back into basic mode. Click Exit to exit the Configuration Interface and display the login page. You will need to type the user name and password to access the configuration again. User Accounts and Logging In To configure AFI-IP, you need to navigate to the device on your network, and then log in using one of the built-in user accounts by providing a user name and a password the Configuration Interface is password protected to prevent unauthorized access. To access the login page, you can either use the network discovery feature described in the previous section or type the IP address into the address bar of your web browser (i.e. either the factory default IP address or the IP address you configured in Chapter 2, Getting Started ). The built-in user accounts each allow different levels of access: Administrator Account provides full access and allows administrators to configure all aspects of the AFI-IP. Technician 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. 28 Basic Configuration

39 Depending on the user account you use, you can either access the entire configuration pages used to view and configure the AFI-IP, or just a subset of the pages. The following procedure assumes you are using Mozilla Firefox 12 or later; however, the same steps also apply to other browsers. To log in to AFI-IP 1 In the address bar of your web browser, type the IP address of device (e.g ). The login page similar to one shown below is displayed. 2 Click Log in to show the password dialog. 3 Type omni for the user name and afi for the password. This logs you in under the built-in administrator account. However, if you are not an administrator, you can log in under either the technician account or the limited user account: you will need to check with your administrator as to the correct user name and password to use. 4 Click OK to log in. Important The password is case sensitive and must be typed in lowercase ensure the Caps Lock key is not active on your computer keyboard. The main page of the configuration interface is the System Status page, which always appears when you log in. It shows the current status of the AFI-IP including the version of the firmware and the serial number of the device. AFI-IP/AFI-IP Plus Product Manual 29

40 Once you have logged in, you can access the various configuration pages to check or make changes to the settings as required. You can also change the password used to login. In the remainder of this chapter, we will discuss basic configuration of your AFI-IP and how to quickly configure it and get it up and running on your network. In the next chapter, we will discuss the more advanced configuration features provided by the product. Important Once you have completed configuring the AFI-IP, you should always exit the Configuration Interface and close the web browser to terminate the current session and prevent unauthorized access to the AFIP-IP settings; otherwise, the login information (i.e., user name and password) might be cached by your web browser and allow others to login using those credentials (see Exiting the Configuration Interface on page 36). 30 Basic Configuration

41 Administrator Account If you log in to the Configuration Interface under the Administrator account, you will see the System Status page and menus shown in Figure 10. Figure 10. System Status page with the administrator account The various configuration pages are accessed by clicking on the menus located on the left-hand panel of the web interface: selecting a menu displays the corresponding configuration page on the right-hand panel of the web interface. As an administrator, you have unlimited access to the Configuration Interface and are responsible for configuring the AFI-IP and setting up the user accounts. Whilst you are logged in under the Administrator account, it is recommended that you change the password of that account so that non-administrators cannot gain unrestricted access to the Configuration Interface. You should also set up the user name and password for both the Technician account and the Limited User account if required. Click Exit to go back to the login page; you will need to enter the user name and password again to access the configuration pages. AFI-IP/AFI-IP Plus Product Manual 31

42 Technician Account Figure 11 shows the configuration under the Technician account. This account provides a limited set of menus and configuration pages and is typically used by technicians to view the status of the system (System Version Information, Current Status, and Channel Information). Additionally, technicians can access several of the Diagnostics pages. Figure 11. System Status page with the technician account Limited User Account Figure 12 shows the configuration when you log in under the Limited User account. This account only shows the System Status and Statistics pages. Figure 12. System Status page with the limited-user account 32 Basic Configuration

43 Configuration Status The Configuration Status section shows the current status of the AFI-IP configuration, and provides several buttons to save or undo any changes you make. You can also reset the AFI-IP to its default settings. The following summarizes the status messages that may appear: Status Message Configuration Unchanged Configuration has been saved. Restart required to take effect. Data is invalid: THE UPDATED STATE 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 AFI-IP, 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 settings, you must save the changes before leaving the page otherwise the changes will be discarded. The Configuration Status area includes the following buttons: Button Save Restart Reset to Defaults Undo Description Saves the current settings on the configuration page to AFI- IP flash memory. Navigating to another page without clicking Save will discard all configuration changes on that page. Restarts the AFI-IP device using configuration settings from flash memory. Resets the configuration settings to the default values. This affects ALL configuration settings; not just the settings on the current page. It does NOT save the configuration settings. Undoes any changes you made by reloading the last saved configuration. This affects ALL configuration settings; not just the settings on the current page. AFI-IP/AFI-IP Plus Product Manual 33

44 Saving the Configuration Settings Once you make changes to the configuration, you should save the changes; otherwise if you navigate to another page, the changes will be discarded. To save the changes, click Save. When you save the changes, the message displayed under Configuration Status changes to Configuration has been saved. Restart required to take effect. advising you to restart the AFI-IP so that the new settings can be used. Figure 13 shows the configuration page when a restart is required (see Restarting after Saving the Configuration below). Figure 13. Restart required after saving the configuration settings Restarting after Saving the Configuration Once you have saved the existing configuration to the AFI-IP flash memory (see Figure 13), you need to restart the AFI-IP for the configuration settings to take effect. Click Restart to restart the AFI-IP, as shown in Figure 14. Warning! Do not disconnect the power to the AFI-IP while it is restarting; otherwise you may damage the device or corrupt the firmware. After restarting the AFI-IP, it is recommended that you back up the configuration to a file on your computer in case you need to restore the settings at a later time (see Backing up the Configuration on page 41). 34 Basic Configuration

45 Note You may need to reload the configuration page in your web browser after restarting the AFI-IP. Figure 14. Restarting the AFI-IP device If you can no longer communicate with the AFI-IP using the Configuration Interface, it is most likely that the IP address of your computer is now on a different subnet than the AFI-IP. If the subnet of your computer is different, you ll need to change it to the same as the AFI-IP device before you can use the web-based Configuration Interface. For further information on how to change the IP address of your computer, refer to Configuring the Basic Network Settings on page 38. Resetting the Configuration to Defaults You can reset the configuration of the AFI-IP to its factory-default settings by clicking the Reset to Defaults button. This resets the in-memory configuration to its default settings, but does not save the settings to Flash memory as indicated by the "NOT SAVED" message shown in Figure 15. Figure 15. Resetting the configuration to default settings To make the changes permanent, click Save. Once the configuration is saved into Flash memory, the new settings will be used the next time you restart the AFI-IP (see Restarting after Saving the Configuration on page 34). AFI-IP/AFI-IP Plus Product Manual 35

46 Exiting the Configuration Interface Once you have completed configuring the AFI-IP, it is recommended that you exit from the Configuration Interface by clicking Exit. This will log you out of the session and load the log-in page; you will need to type your user name and password to log in and access the AFI-IP Configuration Interface again (see to User Accounts and Logging In on page 28). Viewing the System Status Select the System Status menu to display the version information for both the hardware and firmware used in the AFI-IP, and the current status of operation. Figure 16 shows the System Status page under the administrator account. All the values on this page are read-only: you cannot change any of the values on this page. Figure 16. System Status page System Version Information The System Version Information section displays the version information of the firmware that is currently loaded in the product. The AFI-IP uses two microprocessors: the Freescale Coldfire microprocessor performs all of the network and system functions; and a Digital Signal Processor (DSP) performs the audio processing such as encoding and decoding. The AFI-IP Coldfire application version is the version of the main firmware that you can update when a new version becomes available from Omnitronics. Also displayed are the revision of the hardware and the serial number of the product. 36 Basic Configuration

47 Current Status The Current Status section displays the current status information about the operation of the AFI-IP and includes the following: IP Address shows the current address of the AFI-IP. System up time is the elapsed time since the AFI-IP was last reset (displayed as days, hours, minutes and seconds). Free memory shows the unused memory (Kbytes) in the device. General Purpose Input displays the state of the general-purpose opto-coupler input onboard the AFI-IP. VoIP Status The VoIP Status section displays the VoIP status and includes the following: Foreground connected IP devices shows the number of IP devices communicating with the AFI-IP on the foreground channels. This number includes connected IP devices that are not currently transmitting audio. In normal operation this number should be 1. Background connected IP devices shows the number of IP devices communicating with the AFI-IP on the background channels. This number includes connected IP devices that are not currently transmitting audio. In normal operation this number should be 1. SIP Status The SIP Status section will be displayed only if the AFI-IP is configured with SIP enabled: this is the case when an AFI-IP is used in dynamic mode. This section includes the following: Last Event is the last connection-related event that has occurred, and may be one of the following: Idle Completed outgoing call Disconnect No connection exists to a DX-Altus or DX64 system. The AFI-IP is connected to a DX-Altus or DX64 system via a DX-Altus or DX64 IPE card. The status will include the IP address of the DX-Altus or DX64 IPE. No connection exists because the connection was terminated. Current Status is the current status of the connection to the IPE device (DX- Altus or DX64), which can be either Connected or Not connected. AFI-IP/AFI-IP Plus Product Manual 37

48 Configuring the Basic Network Settings Figure 17 shows the basic Network Configuration page that is displayed when you select the Network menu in Basic Mode. You can use this page to configure network settings, such as the IP address, network mask, and the gateway address of the AFI-IP. Figure 17. Basic network configuration page The Network configuration consists of several sections: Basic Settings and Network Settings. 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. Note 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. Basic Settings The Basic Settings section includes only one setting: Device network name is the name presented to the network by the AFI-IP (this name will appear in Network Neighborhood on a Microsoft Windows computer. Note Only alphanumeric characters can be used for the name: it may not contain any spaces or punctuation characters. The maximum number of characters is Basic Configuration

49 Network Settings The Network Settings section allows you to use a DHCP server for automatic allocation of the network settings or to manually specify a static IP address, net mask and gateway address, and includes the following: Automatically obtain IP Address (using DHCP) option is used to allow the AFI-IP to obtain an IP address automatically from a DHCP server. When DHCP is enabled, the static IP address and network gateway address settings will be ignored as appropriate settings will be allocated by the DHCP server. The default setting is disabled. For further information about using a DHCP server, refer to Using a DHCP Server on page 62. Note If you select this option, the AFI-IP will attempt to locate a DHCP server at 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 DHCP, you can use multicast addressing to connect the AFI-IP to an IPE device in your DX-Altus or DX64 system (refer to Multicast Addressing on page 97). Devices can also use local mdns names to connect to each other. Local addressing takes the form of name.local, where name is the Location Name configured on the Network settings page. Static IP Address is the IPv4 address of the AFI-IP, which 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 (the default configuration is to use a static IP address). Netmask is the subnet mask that determines what part of the IPv4 address is used to identify the subnet that the AFI-IP 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 (dotdecimal 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 (dot-decimal notation). The default value is AFI-IP/AFI-IP Plus Product Manual 39

50 Changing the Administrator Password Figure 35 shows the Change Password configuration page that is displayed when you select the Change Password menu in Basic Mode. This page allows you to change the administrator password used to access the AFI-IP Configuration Interface. Figure 18. Changing the password of the administrator account Note The user name of the Administrator account is factory preset to omni and cannot be changed. Only Administrators can change the password of this account. To change the password of the administrator account, type the new password you want to use in the Enter administrator password textbox, and then retype it in the Confirm password textbox. Make sure you save the new password by clicking the Save button, and then restart the AFI-IP by clicking the Restart button; otherwise the new password will not be saved (see Saving the Configuration Settings on page 34). 40 Basic Configuration

51 Backing up and Restoring the Configuration Select Backup/Restore to display the Configuration Backup/Restore configuration page, as shown in Figure 19. Use this page to backup and restore the AFI-IP configuration as a file on your computer. Note It is recommended you back up the configuration for safe-keeping in case it needs to be restored later. When the AFI-IP configuration is restored from a configuration file, it needs to be saved to the AFI-IP to make the changes permanent. Figure 19. Backing up and restoring the configuration Backing up the Configuration to a File Once you have completed making changes to the configuration of the AFI-IP, it is recommended that you back up the configuration file to your computer for safekeeping. The backup process involves saving the existing configuration to a file on the hard drive of the computer you are using to access the Configuration Interface. You will be prompted to select a location on your computer to store the file. The default file name is AFIIP_cfg.bin, but you may rename the file if you wish. AFI-IP/AFI-IP Plus Product Manual 41

52 To back up the configuration 1 Click Backup to open the File Download dialog. 2 Select Save File option, and then click OK to save the configuration. You will be prompted for a folder and file name in the Save As dialog. 3 (Optional) If you want to use a different file name than the default (AFIIP_cfg.bin), type the file name in the File name box. 4 Click Save to download and save the configuration to the specified file. When the download is complete, the configuration should now be backed up to the specified file on your computer. Restoring the Configuration from a File You can restore the AFI-IP s configuration to a previously backed up configuration by restoring it from a backup file on your computer. Once you have restored the configuration, click Save to make the settings permanent in the AFI-IP. The settings will take effect when you restart the device by clicking Restart. The following procedure describes how to restore the configuration. Note Restoring the configuration does not permanently save it to the AFI-IP; it only loads it into memory. You must save the configuration after you restore it to make it permanent. To restore the configuration 1 Click Browse to open the File Upload dialog. 2 In the File Upload dialog, locate the configuration file (e.g. AFIIP_cfg.bin) on your computer, and then click Open. The name of the file is shown under Select Restore Configuration file. 42 Basic Configuration

54 AFI/System Settings Figure 20 shows the AFI Configuration page that is displayed when you select the AFI/System Settings menu in Basic Mode. This page allows you to set the identity of your AFI-IP device. This identity is used when logging into a DX-Altus or DX64 system. Figure 20. AFI/System settings page This configuration page has only one setting as described below: AFI ID is used to uniquely identify your AFI-IP device in the DX-Altus or DX64 system. Note In this release, the AFI-ID setting is not used; however, it may be used in future versions so it is recommended you set it to the same as the IPE device to which it will connect. 44 Basic Configuration

55 VoIP and RTP Configuration Select VoIP/RTP to display the VoIP Configuration, as shown in Figure 21. This page contains two tabs, one for each of the VoIP audio streams used by the AFI-IP to communicate with the DX-Altus Server. The Foreground tab provides settings for the foreground audio stream and the Background tab provides settings for the background audio stream. Figure 21. VoIP/RTP configuration page VoIP and RTP Settings The VoIP Configuration settings affect both the background and the foreground channels, and include the following: Enable SIP option enables or disables SIP (Session Initiation Protocol) that is used to establish and terminate VoIP sessions. To use the AFI-IP in dynamic mode, select the checkbox. To use the AFI-IP in static mode, deselect the checkbox. When you enable this feature, some VoIP parameters will be disabled or greyed out so you cannot change the settings as these parameters are not used in SIP mode. Default: Disabled. SIP UDP Port is the network port number used for making SIP connections. Default: Basic Settings The basic settings on this page include the following parameters: AFI-IP/AFI-IP Plus Product Manual 45

56 VoIP Group Enable enables the VoIP group on this channel and allows the radio device associated with the channel to communicate with the AFI-IP. The default setting is Enabled. Remote IP Address is the IP address of the remote AFI-IP. A valid remote IP address comprises an IP address in dot notation (four octets in the range separated by dots) or a fully qualified domain name. This value should be the same for both the foreground and background channels. In SIP Enabled mode, this value is disabled and is not used. The default is RTP receive port number is the IP port number that is used for receiving audio and control messages: two consecutive port numbers are used and this is the first port number. These values must be different for the foreground and background channels. In SIP enabled mode, the background receive port number is disabled as it is determined as the foreground value plus two. A valid port number is an even number between 1024 and The default port number for the foreground is 5004 and the background is RTP transmit port number is the IP port number that is used for transmitting audio and control messages. Two consecutive port numbers are used; and this is the first port number. Generally these numbers will be different for the different VoIP channels. In SIP enabled mode, the transmit port number is disabled as this value is not used. Allowed Values: An even number between 1025 and Default: Foreground default: Background default: For further information about port numbers, refer to Internet Port Numbers on page 98. Types of Remote Addressing The AFI-IP supports three types of remote addresses: Numeric Addess is an IPv4 address, which consists of 32 bits expressed in a form consisting of four decimal octets separated by periods (dots), called dotdecimal notation. This can be used on a LAN set up 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 Fully Qualified Address is an internet name such as afi-ipunit3.host.omnitronics.com.au. This type of address can be used when the AFI-IP is configured to use an internet domain name server (DNS). Using this type of addressing, the IP address of the remote IPE device will be allocated by a domain name server; and this could be the case for a AFI-IP device that is connected to the internet via an ADSL modem. Multicast DNS Address is a name or local address that is discovered on the local network. Local addresses end in the suffix.local, such as ipe- 52A2156.local. The AFI-IP uses a technology called mdns (Multicast DNS) to locally discover the addresses of other AFI-IP and IPE 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 DNS. However, this can only work on networks that fully support multicasting. 46 Basic Configuration

57 Multicast Addressing Multicast Addressing (multicasting) is a numeric IP addressing scheme that provides an efficient method of sending audio to multiple destinations. To configure the AFI-IP to use multicasting, set the remote address to a numeric multicast address. The AFI-IP will then join this multicast group and will receive and transmit with all devices in the multicast group. For further information about using multicasting, refer to Multicast Addressing on page 97. Device Configuration The page for the device configuration depends on whether you are configuring a standard AFI-IP or the enhanced AFI-IP Plus device the AFI-IP Plus device provides some additional settings. Select Devices from the basic menu to display the basic Device Configuration page, as shown in Figure 22. This page contains nine tabs: one for each of the different types of audio device that may be connected to the AFI-IP. The tabs are labeled as Headset 1, Headset 2/Wireless, Handset, Phone, PC, Aux, Desk Mic, L Speaker, and R Speaker. Figure 22. Devices configuration page for AFI-IP The page for the AFI-IP Plus is similar except the tabs for Headset 1 and Headset 2/Wireless are labeled Headset/Wireless 1 and Headset/Wireless 2 respectively as shown in Figure 23. The settings on the first tab for both devices are the same. However, some additional settings are provided on the second tab for the AFI-IP Plus. AFI-IP/AFI-IP Plus Product Manual 47

Device configuration page for Phone device The basic settings that you can configure on this tab include the following: Disable disables all audio input and output from this device; however, it does not disable control signals from the device. Default: Enabled (i.e. phone enabled). Enable telephone VOX mode enables the AFI-IP to detect telephone activity based on the presence of an audio signal on the line. You should enable this setting if your telephone equipment does not provide a hardware indication that the phone is off-hook. If the phone system provides a hardware signal, you should disable this feature and use the hardware indication instead the VOX mode should only be used if the phone system does not provide a hardware indication. Default: Disabled (i.e. phone VOX mode disabled). Note The VOX mode feature is only for a phone connected via the PABX port. If you use a Phone Line Interface (PLI) or a Line Interface Unit (LIU), you should configure it using the DX-Altus Server Configuration Interface or the DX64 Configuration and Management Utility (DX64CMU) depending on which system you are configuring. Telephone VOX hang-on time (in milliseconds) specifies the time (in milliseconds) that the telephone VOX output will remain active after the signal on the PABX port ceases. This will ensure that the AFI-IP will not stop transmitting until all audio is received. The allowed values are 0 to 5000 milliseconds. The default setting is 100 milliseconds. AFI-IP/AFI-IP Plus Product Manual 53

64 Telephone VOX Threshold adjusts the level at which the incoming phone signal triggers voice detection. The lower the number, the more sensitive is the telephone VOX.

69 Advanced Configuration This chapter discusses the advanced configuration settings of the AFI-IP product, and includes the following sections: Overview Configuring the Advanced Network Settings on page 60 Simple Network Management Protocol (SNMP) on page 62 Changing the Passwords on page 64 AFI/System Settings on page 67 VoIP and RTP Configuration on page 69 Device Configuration on page 72 Overview The AFI-IP provides some advanced configuration features that are only available in Advanced Mode. This mode is used by system administrators and more experienced users to gain more control over how the product is configured. In most cases, the basic mode of operation is sufficient for most users. To switch to the advanced mode, select Go to ADVANCED mode on the menu, as shown in Figure 32. In the Advanced Mode, several pages display additional configuration settings. For example, the Network Configuration page displays additional options under the Advanced Settings heading. Figure 32. Changing to Advanced mode AFI-IP/AFI-IP Plus Product Manual 59

70 Note The advanced and basic modes only affect the settings that appear on the configuration pages and not whether the settings are enabled or disabled. For example, basic mode does not disable any features or settings available in advanced mode. Configuring the Advanced Network Settings Figure 33 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 AFI-IP. The Network Configuration page consists of several sections: Basic Settings, Network Settings, and Advanced Settings. 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. Figure 33. Advanced network configuration page Note 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. 60 Advanced Configuration

71 Advanced Settings The Advanced Settings section configures the Universal Plug and Play (UPnP) and various other advanced settings. 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 AFI-IP will be displayed in the Network Neighborhood on a Microsoft Windows XP or Vista computer. The default setting is Enabled. Enable Telnet option enables the Telnet protocol to be used for remote diagnostics. Boot-loader network support option specifies whether the boot-loader or the main application firmware initializes the Ethernet interface on startup. Clearing this option may help to resolve start-up issues under certain network conditions when the AFI-IP fails to get out of boot-loader mode (and does not start the main application firmware) requiring a power reset. Domain Name System (DNS) Server 1 is the primary Domain Name Server (DNS). The DNS is how an Internet addresses are converted into a numeric (dotdecimal 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). Note DNS settings are not normally required as the AFI-IP does not need to connect with other IP devices. Quality of Service: Differentiated Service Class allows the AFI-IP 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. Possible values: Default, Expedited Forwarding, Class 1 7, Assured Forwarding 1-1 to Assured Forwarding 4-3. Default: Default Syslog host address is the address used for diagnosing faults with the AFI-IP, 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). AFI-IP/AFI-IP Plus Product Manual 61

72 Using a DHCP Server Select Automatically obtain IP Address (using DHCP) to enable Dynamic Host Configuration Protocol (DHCP), which allows the AFI-IP 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 AFI-IP, 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 select the Automatically obtain an IP Address (using DHCP) option, the AFI-IP 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 AFI-IP, you will not be able to connect to the device since you will not know the IP address allocated by the DHCP server. In this case, you can use the menu system and the LCD on the front panel to determine the IP Address of the AFI-IP. Simple Network Management Protocol (SNMP) Figure 34 shows the SNMP Configuration page that is displayed when you select the SNMP menu in Advanced Mode. Use this page to configure the settings for the Simple Network Management Protocol (SNMP). Figure 34. SNMP configuration page 62 Advanced Configuration

73 The SNMP configuration of the AFI-IP includes the following settings: Enable SNMP selects the Simple Network Management Protocol (SNMP) feature. SNMP provides a means to extract status information from the AFI-IP through a network management system. The AFI-IP provides several standard network statistics as well as operator usage statistics. If you intend to use SNMP, this setting should be selected; otherwise ensure it is not selected. For further information about using SNMP, refer to Simple Network Management Protocol (SNMP) on page 102. Read community is the SNMP authentication password needed to read (SNMP GET) values from the AFI-IP. The default community is "public". If left blank, the AFI-IP will set this value to "public" when you save the configuration. SNMP Trap destination and SNMP Trap destination 2 specify the IP address to which the AFI-IP will send SNMP traps. This is also known as an SNMP trap sink address. Generally, it is the IP address of a server 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 SNMP VoIP statistic traps enables the VoIP SNMP Receive statistic reports section of the webpage, including the SNMP statistics interval parameter. Selecting this option will enable the AFI-IP to send a periodic SNMP trap (as set in the SNMP statistics interval) for a specific VoIP Group if either: a) the number of defined RTP Sequence Errors is attained for a particular VoIP group; or b) the number of defined RTP Packets too late is attained for a particular VoIP group. Note The counters for each of these conditions will reset each time the SNMP statistics interval has elapsed. The default value is 900 seconds (15 minutes). SNMP statistics interval specifies in seconds when the AFI-IP will send an SNMP trap for a specific VoIP Group if either: a) the number of defined RTP Sequence Errors is attained for a particular VoIP group; or b) the number of defined RTP Packets too late is attained for a particular VoIP group. Note The counters for each of these conditions will reset each time the SNMP statistics interval has elapsed. The default value is 900 seconds (15 minutes). AFI-IP/AFI-IP Plus Product Manual 63

Use this page to change the password for the Administrator account (you cannot change the user name). You can also change the user name and the password of the Technician account and the Limited account. Figure 35. Changing the password of the administrator account Administrator Account To change the password of the administrator account, type the new password you want to use in the Enter administrator password textbox, and then retype it in the Confirm password textbox. Note Only administrators can change the password of the Administrator account. The user name is factory set to omni and cannot be changed. After changing the password, make sure you save the configuration by clicking the Save button, and then restart the AFI-IP by clicking the Restart button; otherwise the new password will not be saved (see Saving the Configuration Settings on page 34). Under Advanced Settings, administrators can enable two additional types of accounts: a technician account and a limited user account. Administrators can also change the user name and password allocated to each of these account types. Each account provides different access privileges to the menus and configuration pages as discussed in the following sections. 64 Advanced Configuration

75 Technician Account The technician account provides limited access to the System Status, Statistics, and Diagnostics menus. Under the Advanced Settings for Technician, the settings are described as follows: Enable technician user allows users to log in to the Configuration Interface as a technician by using the Technician account. The default setting is Disabled. Technician user name is the user name allocated to the Technician account, and is the user name that must be entered in the login dialog when a user wants to log in under the account. The allowed values consist of text with no punctuation characters, spaces or tabs. The default user name is tech. Technician password is the password allocated to the Technician account, and must be entered into the log into login dialog when a user wants to log in under the Technician account. The allowed values consist of text with no punctuation characters, spaces or tabs. The default is password. Figure 36 shows how to set up the Technician account with the default account credentials. To enable the Technician account, simply select Enable technician user; otherwise the account will be disabled. If you want to change the account credentials instead of using the default user name and password, type a user name in the Technician user name box and a password in the Technician password box.

AFI-IP/AFI-IP Plus Product Manual 65

76 Limited User Account The limited user account provides access to only the System Status and Statistics menus. Under the Advanced Settings for Limited user, the settings are described as follows: Enable limited user allows users to log in to the Configuration Interface as a limited user by using the Limited user account. The default setting is Disabled. Limited user name is the user name allocated to the Limited User account, and is the user name that must be entered in the login dialog when a user wants to log in under the account. The allowed values consist of text with no punctuation characters, spaces or tabs. The default user name is user. Limited user password is the password allocated to the Limited User account, and must be entered into the login dialog when a user wants to log in under the Limited User account. The allowed values consist of text with no punctuation characters, spaces or tabs. The default is password. Figure 37 shows how to enable and set up the Limited User account with the default account credentials. To enable the Limited User account, simply select Enable limited user; otherwise the account will be disabled. If you want to change the account credentials instead of using the default user name and password, type a user name in the Limited user name box and a password in the Limited user password box.

77 AFI/System Settings Figure 38 shows the AFI Configuration page that is displayed when you select the AFI/System Settings menu in Advanced Mode. This page allows you to set advanced settings such as console connection mode, and broadcast forwarding for DX64 systems. Figure 38. AFI/System Settings configuration page in advanced mode Advanced Settings The settings under Advanced Settings determine if the AFI-IP will connect directly to either the DX64 Operator Console software (for DX64 Enterprise systems) or Alto Dispatch Console software (for DX-Altus systems) for multiple sub-rack scenarios. In most cases (and by default), the AFI-IP is configured not to use any special communications with an Omnitronics console and will use a static UDP connection to a particular IPE card for a particular system. However, if your system is one of the following listed below, you must configure your AFI-IP to use the dynamic-connection mode applicable to your system: DX-Altus system configured to use dynamic SIP connections If your DX-Altus system is configured to use dynamic SIP connections for operators (required for multiple system login), then each AFI-IP will need to be configured to use the dynamic-connection mode for DX-Altus systems as well as SIP. DX64 enterprise multiple sub-rack system If your DX64 system is a DX64 Enterprise system that uses DX64 System Server, then each AFI-IP must be configured to use the dynamic-connection mode for DX64 Enterprise systems as well as SIP. These dynamic-connection modes are explained below: AFI-IP/AFI-IP Plus Product Manual 67

78 Console connection mode determines how and whether the AFI-IP communicates directly with an Omnitronics console as well as an IPE in OPR mode. There are 3 modes to choose from: Disable (Single Console) DX64 (DX64 Enterprise Systems) Alto-CCP (DX-Altus) This option is the default setting and is selected when the AFI-IP is used with a single DX64 or DX- Altus system. The Enable SIP checkbox found under VoIP/RTP must be unchecked for this mode to function correctly. This option must only be selected for DX64 Enterprise systems using the DX64 System Server software application. The Enable SIP checkbox found under VoIP/RTP must be checked for this mode to function correctly. This option must only be selected for DX-Altus systems configured to use dynamic SIP connections for operators, or if there are multiple DX-Altus sites available for operators to log in to. Console connection port configures the TCP port used for the either Omnitronics Alto Dispatch Console software (for DX-Altus systems) or Omnitronics DX64 Operator Console software (for DX64 systems)to connect and communicate with the AFI-IP. Default: DX64 Settings The settings under DX64 Settings are only applicable to DX64 systems: you should ensure that these are disabled in DX-Altus systems. If the AFI-IP and the console computer are located on a different network to the DX64 sub-rack, the broadcast status messages sent by the SCU will not reach the DX64 console computer. To resolve this problem, the IPE will re-send these broadcast messages as unicast messages to the AFI-IP, which in turn, can then pass the messages onto the DX64 console computer, either as a unicast or local broadcast message. The following advanced settings control this function. Enable DX64 broadcast forwarding enables the forwarding function for DX64 status messages. Default: Disabled Destination IP address is the IP address of the remote device to which the AFI- IP will forward status messages. This address can be the unicast address of the DX64 console computer or it could be a broadcast address. If the DX64 console computer is using DHCP, you should use a broadcast address as the computer s IP address is not known. UDP Port is the UDP port number used by the DX64 SCU to send status messages. For DX64 systems only, this value is configured using Omnitronics DX64 Configuration and Management Utility (DX64CMU) software it is also configured in the DX64 system configuration file. (For further information about the DX64 system configuration file, refer to the DX64 Operator Console Administrator s Guide.) 68 Advanced Configuration

79 VoIP and RTP Configuration Select VoIP/RTP in Advanced Mode to display the VoIP Configuration page, as shown in Figure 39. This page includes all of the basic settings plus additional settings under Advanced Settings. For information about the basic settings, refer to VoIP and RTP Configuration on page 45. Figure 39. VoIP/RTP configuration page in advanced mode Two tabs of settings are provided: one for each of the VoIP audio streams (i.e., foreground and background) used by the AFI-IP to communicate with the associated IPE device. Foreground provides settings for the foreground audio stream and Background provides settings for the background audio stream. AFI-IP/AFI-IP Plus Product Manual 69

80 Advanced Settings Configure the advanced settings on this page as follows: IP Time To Live (TTL) determines the number of network routers that will forward 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 (default) to 255. When using multicasting, the TTL value indicates the scope or range in which a packet may be forwarded. When configuring a AFI-IP 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 predefined 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 specifies the delay in milliseconds imposed on the received audio. If the AFI-IP 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 20ms. Maximum jitter buffer size specifies the maximum acceptable audio delay (in milliseconds) for received audio. The AFI-IP will automatically adjust the delay (depending on network conditions) to the smallest value possible, thus reducing the received audio delay to the minimum that the network can support. The allowed values are: 100 to 2000ms. The default value is 500ms. 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 heart-beat that maintains the VoIP connection. This parameter must be set identically for both devices that have a VoIP link established. If multicasting is used, all devices in the multicast group must have this parameter set the same. Reducing this value makes it quicker to detect a link disconnection but increases the required Ethernet bandwidth. Alternatively, increasing this value reduces the required Ethernet bandwidth but 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. 70 Advanced Configuration

81 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 AFI-IP 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 71 for a description of each codec). Note Different versions of IPR devices and VoIP phones support different types of codecs the AFI-IP Plus does not support G.729 or G codecs. Encryption: The AFI-IP can encrypt the network data so that a third party is unable to intercept and listen in on conversations. Using an encryption algorithm and enabling encryption will allow the AFI-IP to encrypt all voice and control data. The AFI-IP provides DES 56-bit key encryption algorithm (AES encryption is also available upon request and is subject to approval). The default setting is Encryption Disabled. Encryption key is the string used to encrypt the data. This ensures that no third party can decrypt the VoIP data. If this field is left blank, the default encryption is used. The encryption key is case sensitive. Note If encryption is enabled, then all communicating AFI-IP devices and IPE 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, the VoIP Link indicator will not illuminate. Supported Codecs The codecs supported by the AFI-IP device are listed below. Supported Codecs G.711 PCMU 8000Hz μ-law (i.e. u-law, ulaw, or mulaw) G.711 PCMA 8000Hz A-law G ADPCM 8000Hz GSM 8000Hz Description ITU G.711 Pulse Coded Modulation μ-law.

82 Device Configuration Select Devices in Advanced Mode to display the advanced settings on the Device Configuration page, as shown in Figure 40. For information about the basic settings, refer to Device Configuration on page 47. The page shown here is the one for the AFI-IP Plus product, which shows the additional settings under Advanced Audio Settings for the acoustic shock protection feature. These settings are specific to the AFI-IP Plus product only. All other settings are the same for the AFI-IP product. This page provides one tab for each type of device that can be configured, and allows you to set the output mix mode and the priority level for the audio. Each device with output audio has a set of mixer settings. These advanced settings determine which audio inputs are mixed together to generate the output audio on the device. Note The Phone and the Desk Mic devices do not provide any mixing. The default settings for the audio mix should be suitable for most system installations. It is recommended that you do not modify these settings unless it is absolutely necessary. Figure 40. Device advanced configuration page 72 Advanced Configuration

83 Each audio device provides a list of priorities and available audio channels, depending on which devices have been enabled. For each available channel, the following options are available: Priority specifies the priority level (or importance) of the input source from 1 (the highest priority) to 5 (the lowest priority): a higher priority takes precedence over lower priorities. Output Mix Mode determines how the input sources for the audio are combined and the priority level. The supported values are listed on the following page: Disabled Mix Audio Idle, only active if no higher audio present No audio input is added for this priority level. Causes the selected input source to be added to the audio mix at the selected priority level for the current output device. Causes the selected input source to be added to the audio mix for the current output device only if no higher priority audio is present. Input Sources determines which input source is associated with the selected mix mode of a particular priority level. You can select only one of the available options per priority level for the required output mix mode. Figure 41 shows a typical example of the advanced audio mixing applicable to Headset/Wireless 1. Figure 41. Example of advanced device audio mixing for Headset/Wireless 1 AFI-IP/AFI-IP Plus Product Manual 73

84 In this configuration, the audio for Headset/Wireless 1 is mixed as follows: Foreground audio is given the highest priority and is mixed with the audio for Headset/Wireless 1 as the Output Mix Mode is set to Mix Audio. Background audio is given the next highest priority and is mixed with the audio for Headset/Wireless 1 as the Output Mix Mode is set to Mix Audio. Phone audio is given the next highest priority (the lowest priority) and is mixed with the audio for Headset/Wireless 1 as the Output Mix Mode is set to Mix Audio. What may not be apparent in this example is that the PC and Aux devices are disabled, and therefore, do not appear as options in the Input Sources. Consequently, the number of priority levels available has decreased from five to three with priority level 3 the lowest. Acoustic Protection This section describes configuration settings for the Acoustic Protection (also referred to as Acoustic Shock Protection) this is an enhancement implemented in the AFI-IP Plus product only. If you have a standard AFI-IP product, this section will not apply to you. These settings allow administrators to configure the audio compression and acousticprotection limit of the audio for the headset earphones. The term acoustic shock is used to describe the unpleasant symptoms a person may experience after hearing an unexpected, loud, usually high-pitched sound via a headset. Under the Advanced Settings of the Headset/Wireless 1 tab, several settings are provided to accommodate the enhanced acoustic protection and compression. These settings are Acoustic Protection Limit, Compressor Threshold Level, and Compression Ratio as shown in Figure 42. The settings shown here are the factory default values. Figure 42. Advanced device configuration with the acoustic shock protection Setting the Acoustic Protection Limit The AFI-IP Plus is capable of limiting the peak sound-pressure level (SPL) on output audio. The range of limiting provided is 92dBA to 105dBA inclusive. This range is provided in steps of 1dBA. Figure 43 shows the values available for the Acoustic Protection Limit setting. The setting of the Acoustic Protection Limit in effect on power-up is the setting that was in effect when the configuration was last saved. 74 Advanced Configuration

85 Figure 43. Acoustic Shock Limit settings Compression Settings The output audio of the AFI-IP Plus is capable of being compressed (dynamic range limited). The action of the compressor function is specified via two settings: Compressor Threshold Level and Compression Ratio, both of which are discussed in the following sections. Setting the Compressor Threshold Level The threshold level determines at what level the compressor starts to act. Audio levels below the threshold level are passed through unchanged. The range of Compressor Threshold Level is from 3dB to 24dB inclusive. This range is provided in increments of 3dB. Figure 44 shows the values available for the Compressor Threshold Level setting. Figure 44. Compressor Threshold Level settings AFI-IP/AFI-IP Plus Product Manual 75

86 Setting the Compression Ratio The compression ratio determines the amount of gain reduction above the threshold level. The range of compression ratio provided is from 1.5:1 to 8:1. This range is provided in steps of 0.5. Figure 45 shows the available values for the Compression Ratio setting. Figure 45. Compression Ratio settings The compressor is effectively disabled by setting the Compression Ratio to 1:1. The Compression Ratio setting in effect on power-up is the setting that was in effect when the configuration was last saved. Compressor Functionality The compressor is a top-down compressor and works by reducing the audio output gain above a certain threshold level. This compressor functionality is depicted diagrammatically in Figure 46. Figure 46. Compressor function The AFI-IP Plus uses an RMS-sensing type of compressor in which the RMS level of the audio is calculated and compared to the Compressor Threshold Level. If the RMS level is below the Compressor Threshold Level, the audio will pass through unchanged. However, audio with an RMS level above the Compressor Threshold Level will be attenuated by an amount determined by the Compression Ratio. 76 Advanced Configuration

87 Table 1 lists the dynamic range reductions available for all combinations of settings for a maximum input level. Table 1. Dynamic range reduction (db) for all available settings (for 0dB input) Threshold (db) Ratio : : : : : : : : : : : : : : : For example, with an audio level of 20dB above the Compressor Threshold Level and a Compression Ratio of 2:1, the output audio is 10dB above the Compressor Threshold Level (attenuation of 10dB). The effect on the signal level is shown in Figure 47. The available settings will provide a dynamic range reduction of up to 21dB. Important The Acoustic Protection Limit setting is accurate only for the headset type that you select from the Headset Type list as the AFI-IP Plus is calibrated for these headsets. You should, therefore, ensure you select the correct headset type for the headset you intend to use. Figure 47. Compression effect on signal level with a 2:1 Ratio and -20dB Threshold AFI-IP/AFI-IP Plus Product Manual 77

88 Note The attack rate and the release rate of the compressor are not user configurable as these values are set in the firmware. Acoustic Protection Functionality The acoustic protection functionality works by reducing the gain of any output audio that exceeds the limit set in the Acoustic Protection Limit setting. Any audio output that is below the Acoustic Protection Limit will pass through unchanged; otherwise, any audio output above the Acoustic Protection Limit will be reduced to a level at or below the Acoustic Protection Limit. 78 Advanced Configuration

89 Diagnostics, Statistics, and Upgrading the Firmware This chapter discusses the diagnostics and statistics pages and how to update the firmware in the AFI-IP product, and includes the following sections: VoIP Diagnostics Input Levels Diagnostics on page 81 Output Levels Diagnostics on page 83 Statistics on page 84 Upgrading the Firmware on page 88 VoIP Diagnostics The VoIP Diagnostics page is used to test the VoIP connections and to diagnose any problems with the VoIP configuration. This page provides Foreground and Background tabs, on which you can test the VoIP channels. Figure 48 shows the VoIP Diagnostics page that is displayed when you select the VoIP menu under the Diagnostics in Basic Mode and Advanced Mode. Figure 48. VoIP Diagnostics page The VoIP Diagnostics page includes the following diagnostic tools: AFI-IP/AFI-IP Plus Product Manual 79

90 Restart AFI-IP allows you to restart the AFI-IP by clicking the Restart button. Print Configuration allows you to print the current configuration by clicking the Print button: this opens a new browser window to display the current configuration in a simple table format that you can print. Diagnostic Report allows you to display comprehensive diagnostic information about the operation of the AFI-IP by clicking the Report button: this opens a new browser window to display the report that you can save to a file on your computer or print. Clear RTP Session Statistics clears the RTP statistics for all VoIP channels, however, individual source statistics are not cleared. Output Relay controls the local relay output that is accessible via RLY/OPTO connector on the back panel: you can switch it ON and OFF by clicking the button. SIP URI identifies the SIP entity by specifying a SIP Uniform Resource Identifier (URI). A SIP URL is similar to an address: sip:username@hostname where username is the name of the user and hostname is the address of the SIP server or of the user agent (if the SIP server is not used) Select Connection provides a button to allow you to connect to the SIP server specified by the SIP URL parameter. Channel Diagnostics The channel diagnostics tools appear on the Foreground and the Background tabs, and include the following: Select sound file selects a sound file (in.au format) from a list of sound files: busy.au, ring.au, start.ua, phone.au, and voice.au to either play or send via the network. Play sound (locally) plays the selected sound file to the local AFI-IP device on the selected channels. Transmit sound (send to network) sends the selected sound file to the remote device on the foreground or background VoIP channel(s) using the configured transmit codec for the channel(s). Play Tone (local audio output) transmits a 1kHz tone at the local audio outputs. Transmit tone (send to network) transmits a 1kHz tone to the remote IPE device. 80 Diagnostics, Statistics, and Upgrading the Firmware

91 Input Levels Diagnostics Figure 49 shows the Input Levels Diagnostics page that is displayed when you select the Input Levels menu under Diagnostics in Basic Mode and Advanced Mode. This page provides several tabs, one for each type of device that can be configured, and provides a diagnostic tool to measure levels of the analog inputs: it also provides the ability to adjust the input gain. Figure 49. Input levels diagnostics page The Input Levels page includes the following diagnostics: Input Gain allows you to change the input gain for the analog device selected, but it will not take effect until you save the configuration by clicking the Save button. Measure input level (local audio input) is used to measure the input level of the local audio input (see Measuring the Input Level below). Measuring the Input Level You can measure the audio input level for the selected device and calibrate it using the signal level meter. Click the Enable button to measure the input. This enables the selected audio input and displays the signal level meter with the current audio input signal. It is recommended that you inject a 1kHz tone at -10dBm (or dbu) for testing purposes. Figure 50 shows the signal level meter when the audio input level is calibrated to -10dBm. AFI-IP/AFI-IP Plus Product Manual 81

92 Figure 50. Measuring the audio input level Several points should be taken into consideration while measuring the audio input level: The VU meter on the front panel behaves differently in this calibration mode than when in normal operation. That is, in calibration mode, a signal with a nominal level of -10dBm will cause the first red LED to illuminate, and each LED represents 1dB of signal (in normal mode, the first red LED is 0dBm and each LED represents 3dB). The AFI-IP enables the input under test, so it is not necessary to provide a signal to activate the channel. For example, if testing the PABX input, no off-hook signal is required while testing. The input under test can be tested even if it is disabled in the configuration. Note While measuring the audio input level, normal operation of the AFI- IP Plus is suspended so it will not operate with the DX64 system. You must ensure that you click the Disable button to return the AFI-IP to normal operation once you have finished testing the input levels. Whilst testing the audio input level, if the audio input signal is too low, the signal level meter is displayed similar to the one shown in Figure 51 with a yellow bar; and if the audio input signal is too high, the signal level meter is displayed similar to the one shown in Figure 52 with a red bar. Figure 51. Audio Input signal level is too low 82 Diagnostics, Statistics, and Upgrading the Firmware

93 Figure 52. Audio input signal is too high Output Levels Diagnostics Select Output Levels under Diagnostics to display the Output Levels Diagnostics page, as shown in Figure 53. This page provides several tabs, one for each type of device that can be configured, and provides a diagnostic tool to measure levels of the analog outputs: it also provides the ability to adjust the output gain. Figure 53. Output levels diagnostics page Set output volume adjusts the output gain for the analog device selected, but it will not take effect until you save the configuration by clicking Save. Tone level sets the level of the 1kHz tone generated to either 0dBm or -10dBm. Play Tone (local audio output) enables the output of the 1kHz tone at the configured level when you click Enable. To turn off the tone, click Disable. Note Whilst testing the audio output levels, normal operation of the AFI- IP is suspended. Once you have finished testing, you must click Disable to return the AFI-IP to normal operation. Whilst testing the audio output levels, the associated analog output channel will be enabled even if the channel is disabled in the configuration. AFI-IP/AFI-IP Plus Product Manual 83

105 Bandwidth Usage VoIP devices use RTP (Real Time Protocol) for transferring audio across a network. Each VoIP audio channel requires a certain bandwidth. This bandwidth depends on the compression used to encode the audio, which is determined by the codec used. Omnitronics VoIP devices support several industry-standard codecs with each one providing different levels of compression and audio quality. For a list of codecs supported by the AFI-IP, refer to Supported Codecs on page 71. You can use the following information to calculate the minimum Ethernet throughput requirements in kilobits per second (kbps) for a network between a single console (desktop/laptop computer and AFI-IP) and a DX-Altus Server sub-rack. Upstream (from Console to DX-Altus Server sub-rack) G kbps per operator when transmitting to any number of radio channels GSM 45kbps per operator when transmitting to any number of radio channels Downstream (from DX-Altus Server sub-rack to Console) G kbps per operator when receiving any number of foreground and background channels simultaneously GSM 60kbps per operator when receiving any number of foreground and background channels simultaneously You can use the following information to calculate the minimum Ethernet throughput requirements in kilobits per second (kbps) for a network between the DX-Altus Server sub-rack and IPR100, IPR110+, and IPR400 devices. Upstream/Downstream (to/from DX-Altus Server sub-rack) G kbps per radio channel (TX or RX) GSM 45kbps per radio channel (TX or RX) Other requirements for network connection between DX-Altus components: Dead time (periods of no network connection) must be less than 3 seconds Jitter must be less than 2 seconds as a worst-case scenario Service Availability is an operational requirement to be specified by the client Support is an operational requirement to be specified by the client AFI-IP/AFI-IP Plus Product Manual 95

106 The following discussion calculates the bandwidth usage of a single channel in one direction (note that this is a worst-case scenario as no channel should be on continuously). In the AFI-IP product, voice is converted to a packet every 40 milliseconds and packets are sent at a rate of 25 packets per second. The IP/UDP/RTP overhead per packet is 320 bits. Hence, this overhead adds 8kbps to the bandwidth requirement for VoIP as calculated below. Calculation of VoIP overhead Overhead per packet: 320 bits Packets per second: 25 per second Overhead per second: overhead/packet * packets/sec = 320 * 25 = 8kbps The bandwidth requirement in kilobits per second (kbps) for each supported codec is as follows: Supported codecs G kbps + 8kbps = 72kbps G.726 ADPCM kbps + 8kbps = 40kbps GSM 14kbps + 8kbps= 22kbps Important The bandwidth calculation for each codec is the bandwidth consumed while transmitting on one half-duplex channel. As channels will only transmit when the radio is busy and/or VAD (Voice Activity Detection) is active, the actual bandwidth usage will be lower than these calculated values. In addition to voice packets, the AFI-IP device also sends RTCP (Real Time Control Protocol) packets. However, these are only sent once every 5 seconds, and hence the amount of bandwidth used by these packets is negligible. For a SIP connection, no data is sent at all when a connection is not established. IP Addressing This section discusses the IPv4 addressing scheme implemented in the AFI-IP product: IPv6 is not supported. All devices connected to the internet or using internet protocols for communication have an IP address. An IP address is a 32-bit number. Traditionally, this is shown as four decimal numbers (octets) in the range separated by dots, referred as dotdecimal notation. An example of an IP address is Not all IP addresses are created equal, and certain ranges of address have specific functions. Some addresses are allocated for use as private networks while others are allocated for multicasting. 96 Technical Reference

107 An IP address consists of two parts: the network address and the host address. A computer uses a subnet mask to determine the parts of the IP address. 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 s 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. The different classes of IP Addresses and the range of addresses are shown below. Class Range of First Octect 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 the network (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 third octets (e.g ). The IP address space is controlled by the Internet Assigned Numbers Authority (IANA). Multicast Addressing Multicast addressing or multicasting is a method of implementing efficient one-tomany 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 in an efficient manner is complex. The routers and switches that form the network infrastructure manage this routing for you; and this complexity is not visible to the end devices. End devices simply need to join the group. The range of addresses to is reserved for multicast addresses: when using any address within this range, the AFI-IP will automatically use multicast mode. AFI-IP/AFI-IP Plus Product Manual 97

108 Important Mulicast addresses in the range of 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. Multicast Addresses in the range to are used for internetwide addressing. You should use these addresses for communicating over a WAN or over the internet. Internet Port Numbers An Internet port number is part of the IP header and identifies the type of data being received or transmitted. Internet port numbers are used with TCP and UDP. The UDP port numbers 5004 and 5005 are allocated for Real Time Protocol (RTP) and 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. Furthermore, for a VoIP device that can support more than a single connection, such as the AFI-IP device, a separate pair of port numbers is required for each VoIP connection. If you configure multiple channels to use the same port number, the audio will not work correctly. Domain Name System (DNS) Normally when accessing a web site or computer on the Internet the address is expressed as a hostname or domain name, for example These host names are actually converted into an Internet Protocol address using the Domain Name System (DNS), a computer will communicate with a DNS server that will then provide the actual numeric IP address that corresponds to the hostname. A hostname 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 specified a sub domain of higher domain to the right. Omnitronics IPR products include the support for sending requests to DNS servers and hence converting hostnames into numeric Internet Protocol addresses. 98 Technical Reference

109 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 Internet Protocol 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 with Windows XP, Vista, or Windows 7. 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 IP 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. Dynamic Addressing Most LANs allocate Internet Protocol addresses to computers and devices using a protocol called the Dynamic Host Configuration Protocol (DHCP). The network will have a DHCP server that provides all devices with their addresses. 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 a particular address renews its lease, 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 addresses in the range to AFI-IP/AFI-IP Plus Product Manual 99

110 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. 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. The diagram shown in Figure 57 depicts how NAT is implemented. Figure 57. 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. 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 AFI-IP via an ADSL router that performs address translation, refer to Static Connection with DHCP Multicasting on page 120. VoIP Functionality The AFI-IP implements standardized protocols for VoIP functionality. There are two parts of the VoIP functionality: Sending the audio data uses the Real Time Protocol (RTP) to transfer the audio data. Establishing sessions uses the Session Initiation Protocol (SIP) for dynamically establishing sessions. Real Time Protocol (RTP) Real Time Protocol (RTP) provides a mechanism for sending real-time data, such as audio or video data over an IP network. RTP can be used both with unicast (point to point) and multicasting (point to multi-point). 100 Technical Reference

111 RTP also has a companion protocol called Real Time Control Protocol (RTCP). RTCP does not carry any of the actual real-time data, but provides information to monitor the status of the connection. RTP and RTCP both use User Datagram Protocol (UDP) to send the packets. The control protocol for a RTP link is always sent on the next port number. Signaling with RTP In addition to audio data, the AFI-IP needs to pass information about the E & M control signals. In RTP, a specific packet type can be used for passing this type of telephone signaling (this is defined in RFC2833 for further information about RFC2833, refer to Related Documentation on page 15). This type of packet provides events that can be used for E & M control signals sent as ABCD 4-bit signaling for digital trunks. Encryption The AFI-IP can encrypt the network data so that a third party is unable to intercept and listen to conversations. Using an encryption algorithm, and enabling encryption, allows the AFI-IP to encrypt all voice and control data. Encryption is the process of transforming information (referred to as plain text) using an algorithm (called the cipher) to make it unreadable to anyone except those possessing special knowledge (usually referred to as a key). The encryption key is a text string that is user configurable. If the encryption key string is left blank, then a default string will be used. The AFI-IP product supports the following encryption standards: Data Encryption Standard (DES) is a block cipher with a key length of 56 bits. It is the least secure of the algorithms supported because it uses a short key. Advanced Encryption Standard (AES) is a more modern block cipher that can have a variable key length. The AFI-IP supports both 128 bit and 256 bit key lengths. Note If you enable encryption, then all AFI-IP Plus devices must use encryption with the same encryption type and encryption key. The availability of AES is governed by export regulations, and is subject to approval prior to acceptance of order. AFI-IP/AFI-IP Plus Product Manual 101

112 Simple Network Management Protocol (SNMP) This section provides details about the SNMP functions that are defined in the Omnitronics MIB file, and other useful SNMP functions as defined in the RFC1213 and SNMPv2 MIB files, for Omnitronics SNMP-enabled products. Overview The AFI-IP device supports SNMP version 2c for network management and control. Using SNMP, the AFI-IP provides status and control information for: Firmware version number of the main application and DSP Current state of the operator Push to Talk (PTT) or Busy Monitoring operator activity such as talk/listen counts and conversation times The Management Information Base (MIB) provides complete information for using AFI-IP specific values within a network management system. Should you require further information about these values, Omnitronics technical support can provide a copy in a text file upon request. The AFI-IP provides additional information via the SNMP interface, such as: System Information SNMP Information IP and ICMP Statistics UDP Statistics This information is provided in a standard format as defined by the Internet Standard RFCs and should be understood by all network information systems. The AFI-IP provides detailed operator activity statistics that can be accessed via SNMP. These operator statistics reset every 15 minutes, therefore, your NMS should be configured to poll this information from the AFI-IP every 15 mins so that the information collected is accurate and can be tabulated and graphed. Refer to Table 5 on page 106 for a list of the SNMP operator statistics available in the AFI-IP. The following sections discuss the SNMP functions supported by the AFI-IP and other Omnitronics IPR products. 102 Technical Reference

127 Application Notes This section provides several application notes with details on how to use the AFI-IP in various different configuration environments, and includes the following sections: Overview Static Connection in a Local LAN on page 118 Static Connection with DHCP Multicasting on page 120 Dynamic Connection with Static IP on page 121 Static Connection via ADSL and the Internet on page 124 Overview The Omnitronics AFI-IP product can operate in many different configuration environments and provides the audio and control interface to the DX-Altus or DX64 system. Console operators (operator positions) communicate with the DX-Altus or DX64 system via the AFI-IP over an IP link such as an Ethernet LAN. Each operator position requires an AFI-IP and a computer running the Omnitronics Alto Dispatch Console software (for DX-Altus systems) or Omnitronics DX64 Operator Console software (for DX64 systems), and IP connections to the network. The AFI-IP can connect to a DX-Altus or DX64 system using either a static connection or a dynamic connection. With a static connection, the AFI-IP can be permanently connected to an IPE device and operator position. The AFI-IP will continue to operate even if the console software is not running. With a dynamic connection, the AFI-IP can connect to an IPE based on control messages from the console software. This enables a single AFI-IP to connect to any operator position and to multiple DX-Altus or DX64 systems. Both of these types of connections, and the system configuration for each application, are discussed in the following sections. AFI-IP/AFI-IP Plus Product Manual 117

The Omnitronics Alto Dispatch Console software (for DX-Altus systems) or Omnitronics DX64 Operator Console software (for DX64 systems) controls the AFI-IP allowing it to connect with an IPE device in dynamic connection mode. In dynamic connection mode, the console software provides a database of the IP addresses of the IPE cards. Hence, the console software will override the local settings for the remote IP address and the transmit UDP ports. In the configuration interface, you will see that the values are disabled when the Enable SIP option is selected. Table 13 and Table 14 show the configuration values used at each site.

134 Static Connection via ADSL and the Internet Configuring networks is a complex issue, and there are many different ways that you can set up a network. This example is just one way that you can use to connect an AFI-IP and an IPE on a network. Note If you change the IP address and netmask of the AFI-IP, a situation may occur in which it is no longer possible to access the configuration interface from your computer. If this occurs, you can use the Serial Monitor to change the IP address via the USB port (see Using the Serial Monitor on page 132). In this example, the ADSL router at the operator end uses 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 Network Address Translation (NAT) on page 100. 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 AFI-IP device on the network. Table 15 and Table 16 list the addresses used in this application. Table 15. IP Address details at site A Device Address AFI-IP IP address Console computer IP address ADSL router external IP Address Local LAN Gateway Address Table 16. IP Address details at site B Device Address SCU Master IP address SCU Slave IP address IPE IP address ADSL router external IP address Local LAN gateway address Application Notes

135 Configuring the Network Site A comprises a small network of computers, operator work stations, and an AFI-IP. Hence, the router is configured to use Network Address Translation and Port Forwarding to connect the AFI-IP and the console computer to the Internet. Site B comprises only the DX-Altus (or DX64) sub-rack, so the router is configured to use a Demilitarized Zone (DMZ) to connect the IPE: in this configuration, the IPE is completely accessible from the Internet. Router Configuration for Site A The router at site A is configured to use port forwarding, which simply tells the router to forward the data to a particular computer on the LAN. This allows the IPE at site B to reach ports on the AFI-IP connected to the internal IP address (inside the LAN). The AFI-IP and IPE both use Real Time Protocol (RTP) and Real Time Control Protocol (RTCP); for each RTP channel, two ports are required: the first is for the actual RTP voice data (port 5004), and the second is used for RTCP control and status information (port 5005). Hence, the router at site A will be configured to forward all UDP messages on ports 5004 and 5005 to the local IP address of the AFI-IP on the LAN. The AFI-IP uses two RTP connections one for foreground and one for background so four ports are required (background uses 5006 and 5007 by default). In this example the SCU at site B is configured to use the port number for SCU status messages. In addition, the IPE will forward the broadcast status message sent by the DX-Altus (or DX64) SCU. These packets also need to be routed. Table 17 lists the port forwarding required at site A. Table 17. Port forwarding configuration for router at site A Remote Port Protocol External Local Port Local Address Address 5004 UDP UDP UDP UDP TCP UDP The web server in the AFI-IP uses the TCP protocol and port 80, which are commonly used for web servers. To make the web server accessible via the router, you need to set up port forwarding. As port 80 is commonly used for web servers, it is likely that this port could get scanned by third parties, such as hackers or bots attempting to locate open ports on devices to attack. Therefore, it is recommended that you use a port other than port 80 to forward the web server packets. AFI-IP/AFI-IP Plus Product Manual 125

136 The remote TCP port 8080 will get forwarded to port 80. So the AFI-IP web server will be available via the internet using the URL of Table 18 lists the configuration settings for the AFI-IP at site A. Table 18.

Any address that starts with something other than is an external address. In this case the AFI-IP will direct the message to its gateway address (i.e., the ADSL router at ). 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 Configuration for Site B The router at site B is configured to forward all messages to the IPE in the subrack. This is sometimes described as DMZ Host (or Demilitarized Zone Host) in the ADSL router documentation. Table 19 shows the IP address translation for the router at site B. 126 Application Notes

137 Table 19. 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 from and to the IPE 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.

139 Serial Monitor You can perform basic configuration and diagnostic troubleshooting of the AFI-IP using the built-in Serial Monitor with the USB interface and terminal emulation software such as Microsoft HyperTerminal. This section describes how to use the diagnostics and recovery features of the Serial Monitor to configure the AFI-IP, and includes the following sections: Overview Installing the USB Device Drivers on page 129 Using HyperTerminal to Connect to the AFI-IP on page 130 Using the Serial Monitor on page 132 Resetting to Factory Default Settings on page 135 Overview The Serial Monitor is not intended for normal use. It is only for technicians or Omnitronics support engineers to assist in diagnosing and troubleshooting problems. It is recommended that you use the web-based Configuration Interface to configure the settings in the AFI-IP. Before using the AFI-IP for the first time, you must configure its network parameters to suit your particular environment. Using the Serial Monitor with a serial terminal emulator (you can download a suitable application from the Internet), you can configure the basic network settings of the AFI-IP. The following sections describe how to install the USB drivers and use Microsoft HyperTerminal to configure the AFI-IP with the built-in Serial Monitor. Once you have physically connected to the AFI-IP via the USB port, you can use the built-in Serial Monitor to configure the basic settings of the AFI-IP. Installing the USB Device Drivers The AFI-IP provides a USB 2.0 compliant interface port on the rear panel, labeled as USB SERIAL. This port uses a Type B male USB connector that interfaces to a USB port on your computer. The USB to serial data conversion is done by USB drivers, CP210x USB to UART Bridge VCP Drivers, provided by the manufacturer, Silicon Labs, which you can download from the manufacturer s website at: AFI-IP/AFI-IP Plus Product Manual 129

140 The drivers should also be available on the supplied product CD. Once the driver is installed and the computer is connected via the USB serial interface, you can use a serial port terminal program such as HyperTerminal or TerraTerm to connect to the AFI-IP. This is discussed in the section Using HyperTerminal to Connect to the AFI-IP below. Using HyperTerminal to Connect to the AFI-IP This section describes how to use Microsoft HyperTerminal, the serial terminal emulator originally provided with Windows XP, to communicate with the AFI-IP via the USB interface and the built-in Serial Monitor. Note HyperTerminal is included with Windows XP, but it is not available with later Windows editions you might be able to find a downloadable version of HyperTerminal on the Internet. However, you do not need to use HyperTerminal: you can use any similar terminal emulation software to communicate with the AFI-IP. Once you have set up the communications to the AFI-IP, you can use the built-in Serial Monitor to configure the basic settings of the product. Using HyperTerminal to communicate with the AFI-IP 1 Click Start, point to All Programs, point to Accessories, point to Communications, and then click HyperTerminal. The Connection Description dialog is displayed. 2 In the Name box, type a name that describes the connection (e.g., AFI-IP). 3 In the Icon list, select an appropriate icon, and then click OK. 4 In the Connect To dialog, choose which port you want to use in the Connect using box. 130 Serial Monitor

141 Note USB ports on your computer should automatically appear as virtual COM ports (e.g., COM5). 5 Click OK to open the Properties dialog for the selected port. 6 Under the Port Settings, set the values as follows: Bits per second: 19200, Data Bits: 8, Parity: None, Stop bits: 1, and Flow control: None. 7 Click OK. 8 In the HyperTerminal window, press the Enter key. You should now be connected to the built-in Serial Monitor on the AFI-IP, and see the afi-ip+ $ or afi-ip $ command prompt. AFI-IP/AFI-IP Plus Product Manual 131
