11 Chapter 1 Introducing the 960SIP Console This chapter provides an introduction to the 960SIP Console and includes the following sections: What is the 960SIP Console? 960SIP12 Selector on page 3 960SIP6 Selector on page 4 IPR120 Front Panel on page 5 IPR120 Back Panel on page 6 Connectors on 960SIP Console on page 7 960CC/CSD Connector Changes on page 7 What is the 960SIP Console? The 960SIP Console is a 6- or 12-channel console that uses IPR VoIP technology to connect remote radios to the console. It can be configured with a number of options including: channel change capability, dual-tone multiple-frequency keying (DTMF), selective calling (selcall), and handset operation. The 960SIP Console consists of a SIP Selector (960SIP12 for the 12-channel version or 960SIP6 for the 6-channel version), an IPR120 for the VoIP Interface, and a communications console or handset for the audio interface: 960CC (standard Communications Console), 960CSD (Communications Console with Selcall and DTMF), or 960HS Handset. The 960SIP console started out by only supporting SIP connections to the VoIP-based IPR radio gateways devices, hence the name 960SIP. However, support for multicast was later added, but the SIP part of the name stuck. Figure 1 shows the 960SIP Console and the available configurations and connections for the 6- and 12-channel interface. 960SIP Console Product Manual 1

16 Chapter 1 IPR120 Back Panel The 960CSD-960SIP12 is connected to the IPR120 using two cables: The handset cable has two 6-way modular connectors at each end. This cable connects between the Audio Line In/Out connector on the 960CSD-960SIP12 and the Handset port on the front panel of the IPR120. The serial data cable has a DB9 male connector at the end which connects to the IPR120. The other end of this cable connects to an internal 8-way connector at the 960CSD-960SIP12. The IPR120 is powered via the 12VDC power connector on the back panel. The 960CSD- 960SIP12 is powered from the Handset port on the front panel via the interconnecting Audio Line In/Out to Handset cable. If you intend to use a plug pack to power the IPR120 (960SIP Console), ensure the plug pack can supply at least 750mA 1A is recommended). Figure 5 shows the back panel of IPR120. Figure 5. Back panel of IPR120 Connectors on 960SIP Console There are a total of five connectors on the 960CSD-960SIP12 that provide connections for serial data, headset, desk microphone and digital inputs and outputs. These connectors are described in Table 2. A headset/footswitch combination or a desk microphone may be connected to the two 8-pin DIN connectors on the 960CSD-960SIP12. Table 2.

17 The 960CSD also has two ports on the rear panel for connecting a headset and footswitch combination or a desk microphone with a PTT switch. When using a headset, connect the headset to the HEADSET port and the footswitch to the DESKMIC port, as shown in Figure 6. Figure 6. Rear view of 960CSD and 960SIP12 When using a desk microphone with a PTT switch, connect the desk microphone to the DESKMIC port. An optional footswitch can be connected to the HEADSET PORT. For further information, see the product manual for the 960 Series Consoles & Handsets. 960CC/CSD Connector Changes Please note that some of the connectors on the 960CC/CSD consoles have changed and some new connectors have been added. The changes relate to the replacement of the 960A43 PCB shown in Figure 7 with the newer 960A57 PCB shown in Figure 8. This was done to provide more options and to increase compatibility with similar devices. Table 3 on page 9 provides a summary of these changes to the connectors. 960SIP Console Product Manual 7

23 Chapter 2 960SIP Console Operation This chapter discusses the operation of the 960SIP Console (960SIP6 and 960SIP12) and includes the following sections: Audio Controls on page 14 Selcall/ANI on page 14 Selcall/ANI Call Queue on page 16 Channel Change on page 17 Mute Control on page 18 Setting the Time on page 19 Channel Selection on page 19 Configuration on page 20 IPR120 VoIP Adaptor on page 20 Figure 11 shows the front view of the 12-channel version of the 960SIP Console consisting of the 960CSD and the 960SIP CSD Sel cal l & DTM F TI ME / QUE UE DATE / POSI TIO N SIZE 9 60 SIP12 S I P S E L EC TO R LEVEL 10 5 MIC TX SELCALL T-FER C L CHANNEL OPEN / CALLED QUI ET BUSY OFF MO N ON OFF MO N ON BUSY C H C ALL BUSY CLEAR M UTE I / COM PTT VOLUME * 0 # SH IFT BUS Y PO WER OFF MO N ON Figure SIP Console front panel showing 960CSD and 960SIP12 960SIP Console Product Manual 13

24 Chapter 2 Audio Controls The 960CSD features the MUTE, I/COM, PTT and QUIET keys, which are the fundamental Console controls. Monitoring a Channel On the 960CSD extended selector panel, select the channel (or channels) to monitor by moving the lever switch (or switches) to the MON (background) position. Note In the MON position, you cannot transmit on the channel. If a call is received, use the volume control to vary the level of the received audio. The status LED above the channel switch will flash. You can also monitor in the ON or foreground position. Just remember that pressing a PTT will cause the channel to transmit. The received level in background mode is the same as the level in foreground mode. Mute Mute blocks all incoming audio to the Console including BUSY and PTT signals. Intercom The 960SIP12 console has an intercom function. This allows the operators audio to be sent to all other console positions. Simply press the I/COM button on the 960CSD and speak. PTT The PTT (Push-To-Talk) button is used to initiate the transmission of audio. For example, select the channel (or channels) to transmit on by moving the lever switch (or switches) to the ON (foreground) position. Press the PTT button and speak. The status LED above the channel will come on constantly while transmitting. Quiet Blocks all audio from the Console s speaker (i.e. closes speaker), but unblocks or opens it when a Selcall is decoded. Selcall/ANI The 960SIP12 is capable of transmitting and receiving tone-sequences that conform to the Selcall/ANI scheme of radio addressing. This functionality is configurable allowing the tone set sequence composition and tone period to be established for a variety of call types SIP Console Operation

25 Figure 12 shows the 960CSD display. The region above the TX SELCALL label displays the current Call Address. The number of digits displayed here corresponds to the number of tones selected for the Call Sequence (see the 960 Series Consoles & Handsets Product Manual 960Y0 for details regarding the configuration of this device). TIME/ QUEUE DATE/ POSITION SIZE TX SELCALL CHANNEL Figure CSD display Normal Calls Use the numeric keypad to enter the address to call. If the Console is configured without a SELCALL status digit, then each digit entered appears in the right-most digit position, with the entry of subsequent digits shifting all previously entered digits one place to the left. This gives the impression that digits are scrolling in from the right. To call the address, press the CALL key. Replying to Calls If the Console has successfully decoded a received call and it is configured to do so, the caller s address will be placed into the ANI queue. At the same time, the caller s address is also placed in the 960CSD s transmit buffer, which will be displayed above the TX SELCALL label. So to reply to a call, simply press the CALL key after a call has been received. Group Calls For convenience, a sequential group of numbers may be called by calling a single number instead of manually calling each in turn. For example, to call all addresses from to 12399, use the # (Group) key. That is, enter the number 123##, where the # symbol would actually be displayed as the digit used to represent the Group code (see the 960 Series Consoles & Handsets Product Manual 960Y0 for details regarding the configuration of this device). Press the CALL key to call all of these addresses. Note To decode group calls, all radios within a particular network must use the same Group tone. Status Calls The last digit in a sequence can be interpreted as the status digit. This scheme enables the significance of a call to be immediately understood without the calling party needing to actually verbalise the intent. The Console must be configured for Status Entry Mode (see the 960 Series Consoles & Handsets Product Manual 960Y0 for details regarding the configuration of this device). 960SIP Console Product Manual 15

26 Chapter 2 When digits are entered in this mode, they scroll in from the second last digit position thereby preserving the last digit. To enter the status digit, press the * key. Subsequent digit entry will keep overwriting this status digit. Press the CALL key to send the call. A reset digit may also be assigned (via the CP960), which enables digits A - F to be used as the status digit. To insert this digit, press the # key after pressing the * key. Automatic Calls If the 960CSD has been configured to expect an acknowledgement in response to making a call (see the 960 Series Consoles & Handsets Product Manual (960Y0) for details regarding the configuration of this device) and it does not receive that acknowledgement within the Acknowledgement Window, then it will re-send the call without any Operator intervention. The Console will, however, notify the Operator that it is performing an AutoCall by issuing a distinctive ticking sound. When the correct acknowledgement is received, or the number of retries has been exceeded, then the Console will cease the AutoCall. Selcall/ANI Call Queue If the 960CSD successfully decodes a call and it is configured to do so, it will place the number into the ANI Queue. This address will be displayed underneath the TIME/QUEUE label. If there are no numbers in the Queue, the Console will display the time and date underneath the TIME/QUEUE and DATE/POSITION labels. As calls are decoded, ANI information replaces time and date information. If the Operator wishes to know the time and date while ANI information is currently displayed, press the SHIFT key then the * key. The time and date will be displayed for five seconds before reverting to display the ANI information. Emergency Calls A successfully decoded call will only be interpreted as an Emergency call if the Console is configured to do so (see the Interpret Last Digit As Status option in the 960 Series Consoles & Handsets Product Manual (960Y0) for details regarding the configuration of this device). When an Emergency call is decoded the Console will issue a persistent melody and will flash the Open/Called LED in distinctive pattern until given attention by the Operator (i.e. by pressing any key). This number is placed at the top of the Queue as well as being placed in the transmit buffer for an immediate reply. Urgent Calls In a similar manner to the Emergency call, the 960CSD will also interpret other addresses that are given special significance. However this scheme doesn t rely on the Status digit, but rather is a specific tone sequence that is completely configurable (see the 960 Series Consoles & Handsets Product Manual (960Y0) for details regarding the configuration of this device). The console will behave in the same manner as receiving an Emergency call except that the melody and LED sequence is distinctly different (ideally, over time, an Operator should be able to identify such calls by the Console s type of notification). These calls are placed in the Queue above Normal calls, but below Emergency calls SIP Console Operation

27 Normal Calls Decoded calls that aren t interpreted as either Emergency or Urgent are treated as Normal calls and are inserted into the Queue below the other two types. Using the ANI Queue The ANI Queue can store up to ten calls before subsequent calls are lost or are unable to be placed into the Queue. Calls are entered into the Queue in historical order. That is, the oldest call is displayed at the top of the Queue. In addition to the historical order, calls are sorted according to their priority, with Emergency and Urgent calls at the top followed by Normal calls. In this way the calls with greatest priority should be serviced in the first instance, followed by calls that have been in the Queue the longest. Navigate through the Queue using the Up/Down keys. The position of a number in the Queue is displayed under the DATE/POSITION label and the total number of calls in the Queue is shown under the SIZE label. This line of text will also give an indication of the contents of the Queue to the Operator, by either flashing or not flashing. There are three possibilities. If there are only Normal calls in the Queue then this line of text won t flash. If the currently displayed Queue item is Emergency or Urgent, then the whole line will flash. Lastly if the currently displayed Queue item is Normal and there are priority items in the Queue, then the number displayed under the TIME/QUEUE label won t flash, but the Queue position and size text will flash (i.e. indicating that there are priority items in the Queue). Transferring Calls To reply to a call in the Queue, locate the number using the Up/Down keys, press the SHIFT key then press the TRANSFER key. This transfers the number into the Console s transmit buffer. Press the CALL key to send the call. The number remains in the Queue. Clearing Calls To remove a call from the Queue, locate the number using the Up/Down keys, press the SHIFT key then the press the CLEAR key. Channel Change The 960CSD is also capable of transmitting DTMF tones. This enables the Console to communicate with a 970 Channel Change Decoder or an IPR110Plus allowing the Operator to change, query, or reset the current radio channel. Changing Channels on a Channel Change Radio To effect a channel change on a radio that has channel change facilities, select the radio channel by moving the lever switch to the ON (foreground) position. Note This channel must be the only channel in the foreground mode. 960SIP Console Product Manual 17

28 Chapter 2 The current channel is displayed above the CHANNEL label on the LCD. Press the CHANNEL key to change, query or reset the radio channel. The channel number will flash while in this mode. Note This mode will time out after five seconds after which time, the Console will revert to normal operational mode. Enter the desired channel via the keypad and press the CALL key. If the action was successful, the new channel number will now be displayed (the display will stop flashing). If unsuccessful, will be displayed instead. To query the current channel, press the CHANNEL key, and then press the CALL key. The current channel will then be displayed. To reset the Channel Change Decoder, press the CHANNEL key followed by the * key, and then press CALL. Querying a Channel Change Radio As the 960CSD console cannot dynamically update the selected channel display (for example, if another console changes the channel), a query function can be used to discover what channel a channel change radio is set to. To effect a query on a radio that has channel change facilities, select the radio channel by moving the lever switch to the ON (foreground) position. Note This channel must be the only channel in the foreground mode. On the 960CSD, press the CHANNEL button, and then press the CALL button. Make sure these key presses are completed within 5 seconds. Once CALL has been pressed, the 960CSD waits for an acknowledgement and the channel number entered will flash. Once the acknowledgement is received, the display will stop flashing and the new channel number is displayed. If more than one channel is in the foreground while attempting to do a channel change, the 960CSD will emit a busy type signal (four beeps) and the display will show dashes. If after a channel change, no acknowledgement is received by the 960CSD after 10 seconds, the busy signal will sound and the display will show dashes. Mute Control The 960CSD is in the open or unmuted state whenever you can hear audio traffic through the front speaker. However, if you need to concentrate on another activity, you can mute the console at any time to block the audio this is different to turning the speaker volume level down via the volume knob on the front panel. The console can be muted in two ways. To unconditionally block all incoming audio from the Console, press the MUTE key. This action inhibits the BUSY and PTT control signals, which effectively disables the Console from receiving incoming Selcalls. This key has a toggle action so pressing it again will unmute the Console. Pressing the QUIET key also mutes the Console; however the difference is that the Console will still decode incoming SELCALLs. Combined with the configurable mute control items detailed in subsequent sections, the Console will automatically un-mute. This method of muting the Console ensures that calls aren t missed SIP Console Operation

29 Setting the Time The Console s date and time can be set only while in Shift mode. Press the SHIFT key and the word SHIFT will replace the current channel number. Shift mode will time out after four seconds of keyboard inactivity and the Console will revert to normal mode. To set a time/date parameter, press one of the following keys while in Shift mode and then enter the desired value. Press # to confirm the change or * to quit back to Shift mode. 1 - set hour 2 - set minute 3 - set AM/PM (any key toggles selection) 4 - set day 5 - set month 6 - set year 7 - set 12/24 hour mode (any key toggles selection) Note Option 3 (set AM/PM) is not available in 24-hour mode. Any value may be entered for any time/date parameter, however the Console will silently reject invalid values, leaving the original value unchanged. Channel Selection The 960 Selector (i.e. 960SIP6 or 960SIP12) is capable of selecting channels in the Foreground or Background group. Figure 13 shows the two selectors. Figure SIP6 and 960SIP12 Selectors When the operator presses the PTT, the operator's audio is transmitted on all channels in the Foreground only; however, audio received on both Foreground and Background channels will be heard by the operator. The selection of channels is accomplished using the 960 Selector. 960SIP Console Product Manual 19

30 Chapter 2 The channel Busy LED above each selector switch indicates: OFF FLASH ON Channel not busy Busy PTT occurring With all the channel selector switches set to "OFF", no audio can be received or transmitted from the console. To monitor particular channels, set the appropriate selector switches to the MONITOR position. Up to 12 channels can be monitored through the console loud speaker. Push to talk is not active on any monitored channel. The LED immediately above the selected channel switch indicates any busy condition or PTT on another console. Any voice on the monitored channels, either incoming or from another console talking on that channel will be heard. To engage the PTT facility for a particular channel (or channels), move the selector switch to the ON position. All channels selected in this manner will receive and transmit audio. Each console in the system is independent of the other s switch selections. For example, a console may be set up as follows: Console CH1 CH2 CH3 CH4 CH5 CH6 A OFF OFF MON ON OFF ON B MON OFF MON ON OFF ON C MON ON MON OFF OFF ON In this situation, console B is monitoring channels 1 & 3, channels 2 & 5 are OFF and two-way communications are available on 4 & 6. Configuration The 960CSD and 960SIP12 as a component of the 960SIP12 will be appropriately configured at the factory although the capability to change some parameters does exist using the PC application 960CP. It is not recommended to change any parameters as the current settings have been optimized for the 960SIP12 application. Further details regarding the 960CP application may be found in the document 960CSD Console Product Manual. IPR120 VoIP Adaptor The IPR120 is a member of the IPR product family. It uses VoIP protocols to connect and disconnect to other IPR devices as required. The IPR120's handset port provides a balanced, half-duplex, connection. The audio from handset ports is digitized using a Codec and G.711 compression. However, an on-board DSP allows further compression down to 13kbps, using a GSM-compliant algorithm. The audio is then transported over IP. The IPR120 can be re-configured within the LAN or WAN environment as shown in Figure 14, via a dedicated graphical user interface. Each unit can be configured for mode of operation, compression level, audio adjustments and signaling parameters SIP Console Operation

33 Chapter 3 Connecting the IPR120 This chapter includes step-by-step instructions for connecting the IPR120 to your network and to get it up and running quickly. All the settings are configured using the built-in configuration interface. This chapter includes the following sections: Connecting to the Network Connecting with Windows on page 24 Connecting to the Network The Omnitronics IPR120 includes a built-in web server called the Configuration Interface. You use this interface to configure the settings in your IPR120. Before you can access the configuration interface, you need to ensure that your computer and the IPR120 are both on the same network. The recommended method of connecting the IPR120 to a computer via an Ethernet network is to use an Ethernet network switch. However, if a switch is not available, you may connect a computer directly to the IPR120 using an network cable you do not need to use a cross-over cable as the Ethernet port is MDIX compatible and can auto-detect the line condition. When connecting the network cable from the IPR120 to the switch, the ETH Link LED on the front panel of the IPR120 should illuminate. If this LED does not illuminate, you may have a problem with the network cable the computer will not be able to communicate with the IPR120 until the problem is corrected. This indicator will also flash whenever the IPR120 detects activity on the network. If the network switch supports 100Mbps, the 100M LED on the front panel will illuminate. Where IP addresses are specified, these are only examples and suitable addresses for your application must be used. When you apply power to the 960SIP12, if the status lights on the 960SIP12 Extended Selector blink continuously, then the serial connection between the IPR120 and the 960CSD is not working. If the IP address of your computer is on a different subnet to the IPR120, you will not be able to access the configuration interface. In this case, you will need to temporarily change the IP address of your computer to a similar address before you can login to web server. Once you have logged in, you can then access the web-based configuration interface to configure the network settings of the IPR120 to match your network. 960SIP Console Product Manual 23

34 Chapter 3 Connecting with Windows This section includes information to help you get the IPR120 up and running quickly using Microsoft Windows 7/8/8.1/10 operating system. Before you can access the IPR120 configuration interface, you need to ensure that your computer is on the same subnet as the IPR120. IPR120 is configured with a static IP address as follows: for devices with an even-numbered serial number for devices with an odd-numbered serial number If the IP address of your computer does not have a compatible address (that is, an IP address starting with x), you will need to temporarily change its IP address before it can connect to the IPR120 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 priviledges. Step 1: Determine the IP address of your computer You can determine 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. 24 Connecting the IPR120

35 2. Click Network and Internet. 3. On the Network and Internet window, click Network and Sharing Center. 4. Under View your active networks, click Local Area Connection to open the Local Area Connection Status dialog. 960SIP Console Product Manual 25

The settings of interest are the IPv4 IP Address, the IPv4 Subnet Mask and the IPv4 Default Gateway. 6. Record the details for IPv4 IP Address, IPv4 Subnet Mask, and IPv4 Default Gateway from the Network Connection Details, then and click Close. Step 2: Change the IP settings of your computer Before you can connect to the IPR120, you need to temporarily change the IP settings of your computer to match the IP settings of the IPR120. If the IPv4 Address of your computer (see Step 1: Determine the IP address of your computer on page 24) 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 IPR120 without any changes to its IP settings. In this case, you can skip to Step 3: Connect the IPR120 to the computer on page 28. However, if the IPv4 Address of your computer does not start with the numbers x, it will be necessary to temporarily change the IP address of your computer. Important Ensure you record the current IP settings so that you can restore your computer to its original configuration after you have finished configuring the IPR Connecting the IPR120

38 Chapter 3 Step 3: Connect the IPR120 to the computer This step connects the IPR120 to the computer via an Ethernet network. The recommended method of doing this is to use an Ethernet switch or router. However, if such a switch or router is not available, you may connect the computer directly to the IPR120 using an Ethernet network cable. Note If you are using a direct connection, you do not need to use a cross-over cable as the Ethernet port is auto-mdix compatible. When connecting the Ethernet cable from the IPR120 to the Ethernet switch or router, the Link indicator will illuminate. If this indicator does not illuminate, you may have a problem with the network cable; and the computer will not be able to communicate with the IPR120 until you correct the problem. Step 4: Configure the IPR120 network settings This step uses the web-based configuration interface to configure the network settings of the IPR120. To configure the IPR120 network settings 1. Start your web browser and type the IP address ( or ) of the IPR120 device in the address bar. Note All IPR120 devices leave the factory configured with one of two possible IP addresses: for devices with an even-numbered serial number for devices with an odd-numbered serial number The web-based Configuration Interface should show the log-in page similar to the one shown below. 28 Connecting the IPR120

39 2. Configure the network settings of the IPR120 to match the network settings of your computer network. Note For details on how to configure the network settings of the IPR120, refer to Network Settings in Chapter 4, IPR120 Basic Configuration on page 38. Step 5: Restore the network settings of the computer Once you have configured the network settings of the IPR120 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 26 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 24. 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 IPR120 to communicate on your network, and you should now be able to connect to the IPR120 using the original network settings of your computer. 960SIP Console Product Manual 29

The number of IP devices communicating with the IPR device. This number includes connected IP devices that are not currently transmitting audio. The last received SELCALL (if the IPR device is configured for SELCALL). Note The last received SELCALL status will appear in the screen capture shown at the top of this page only when the IPR120 is configured for SELCALL. 960 Extended Selector Status The 960 Extended Selector Status on this page provides the following: Communication Status shows the communication status of the link between the 960ES Extended Selector and the IPR120. If the IPR120 cannot communicate with the 960ES (e.g. the serial cable is disconnected), the status will show Fail. Intercom indicates the state of the intercom button located on the connected 960 console. ON indicates that the operator is currently transmitting to other consoles. Push to Talk indicates the state of the console PTT. This can be activated by: the PTT button on the connected 960 console, the PTT switch on a connected desk microphone, or a connected footswitch. ON indicates that the operator is currently transmitting to selected radio channels. Switch Status The Switch Status shows the current status of the 960ES switches. This is represented as a numbered box per switch as shown in Figure 19. Switch number and state Shows the number of the switch and its state Connection status Shows the status of the VoIP connection for this channel Figure 19. Switch status Channel status Shows the activity status for this the channel 36 IPR120 Basic Configuration

47 Each box contains three lines of information about the switch as described below: Line 1: Switch number and position The number represents the number of the physical switch and the position can be one of the following states: OFF Indicates the switch is in the off position and the operator cannot transmit or listen to this channel MON Indicates the switch is in the monitor position and the operator can listen to, but cannot transmit to this channel ON Indicates the switch is in the ON position and the operator can both listen to and transmit to this channel Line 2: Connection status This can be one of two states: Not connected Indicates the VoIP connection is down for this channel. This is normal for when the switch is in the OFF position. However seeing this state for a switch that is in the MON or ON position indicates there is either a problem with configuration, the network, or with the receiving device and requires investigation. Connected Indicates the VoIP connection is up for this channel. Line 3: Channel status Indicates the activity status of the channel, which can be one of the following: IDLE Indicates there is no activity on this channel PTT Indicates the operator is currently transmitting on this channel Busy Indicates the IPR120 is receiving a busy signal from a connected device on this channel, and the connected 960 console will be playing out the audio to the operator. Note that if multiple channels are busy, the audio will be mixed together as it is played out the 960 console. SIP Status The SIP Status shows the current status of the SIP connections and comprises two sections as follows: Current active connections Indicates how many SIP connections are currently established. When an operator sets a 960ES switch to either the ON or MON position, the IPR120 will make the configured connection to that channel. As there can be either 6 or 12 switches to a 960ES, there can be a maximum of 12 SIP connections at once. Status Shows the status of the last SIP event that occurred as well as any errors that may have occurred if the connection failed. For example, if the last event was the operator moved a switch from OFF to ON and established a connection, the status will indicate Completed outgoing call: RTP remote [IP address] : [Port number]. 960SIP Console Product Manual 37

Basic network settings Basic Settings Location Name: This is the name assigned to the installation site. It is also the value that will appear in the Network Neighborhood on a Windows PC and can also be used to access the device by name on a local network. Allowed Values: Alpha Numeric String Must not contain spaces or punctuation marks. (maximum number of characters: 100). Default: The default name is the type of device followed by the units serial number. For example: IPR120 with serial number 52A1212 would have a default name of IPR120-52A1212. Network Settings Automatically obtain IP Address (using DHCP): Click here to enable Dynamic Host Configuration Protocol (DHCP) which enables the IPR120 to obtain an IP address automatically from a 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. When this check box is checked the other network settings will be disabled. Default: Disabled. 38 IPR120 Basic Configuration

49 Static IP Address: This is the IP address of this IPR120. Allowed Values: A valid IP address, four numbers in the range separated by period characters. Default: or If you are configuring a static IP address for the IPR120 and you intend to use it on a local network, you would generally allocate an address between the ranges of to , to , or to as these are especially reserved addresses for private use. Netmask: This is the subnet mask. Allowed Values: A valid IP mask, four numbers in the range separated by period characters. Default: Gateway Address: This 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. Allowed Values: A valid IP address, four numbers in the range separated by period characters. Default: Note If you use automatic IP addressing and there is not a DHCP server available, the IPR120 will attempt to locate a server on start up. If it cannot find a server it will automatically assign itself an address in the range x.x. In this case the IPR120 will take an extra 10 seconds to start.. Note When using automatic addressing (DHCP), it is not possible to know the IP address of the IPR120. In this case, multicast addressing can be used to connect two IPR120 devices or devices can 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. 960SIP Console Product Manual 39

Two consecutive port numbers are used, this is the first port number. Allowed Values: An even number between 1025 and Default: SIP Console Product Manual 41

52 Chapter 4 Internet Port Numbers An Internet port number is part of the IP header and identifies the type of data being received or transmitted. The 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. Also in the case where a VoIP device that can support more than a single connection, such as an Omnitronics IPR400, a separate pair of port numbers is needed for each VoIP connection. Remote Addressing The IPR120 support three types of remote addresses. 1. Numeric: The first is a numeric IP address in the form NNN.NNN.NNN.NNN, where each NNN is a number in the range 0 to 255. 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 Name: If the IPR120 has been configured to use a Internet name server or DNS server, then the remote address can be an Internet name, such as ipr100unit3.host.omnitronics.com.au. To be used in this way the remote IPR device will have its address allocated by a name server, this could be the case for an IPR device that is connected to the Internet via an ADSL modem. 3. Local Name: The IPR120 uses a technology called mdns (Multicast DNS) to locally discover the addresses of other IPR devices on the local network. In this case a name can be used to work out the address of the remote device without requiring an external server. However, this can only work on networks that fully support multicasting. It is recommended for setting up a LAN that supports dynamic addressing. Local addresses end in the suffix,.local. For example; ipr100-52a2156.local. Factory Default Addresses IPR120 devices can only communicate with each other via the intercom by default using the multicast address of on port There are no default remote SIP/RTP addresses configured when the unit is new or if it has been reset to defaults you will need to configure these manually. Multicasting Later versions of the 960SIP Console software support IP Multicast Addressing. This addressing scheme does not make use of SIP connectivity, which is still an option. Multicasting can be used to send VoIP to a group of devices with a single transmission. The 960 SIP console can use multicast for intercom and radio connections. It is bandwidth efficient, allows more devices to share audio and is simpler to configure compared to unicast and SIP connections. To configure an IPR120 to use multicasting, simply set the Intercom and/or Remote Device URIs to multicast IP addresses instead of sip addresses. The IPR120 will join all multicast groups configured, after which it will transmit and receive to/from all devices in the groups. 42 IPR120 Basic Configuration

53 To use multicast effectively, you require the appropriate network infrastructure comprising: a) LAN with all devices connected to a single unmanaged switch; or b) LAN/WAN with managed switches and routers all of which support, and are configured for, multicasting. If you cannot provide a network that matches one of these configurations, multicast cannot be used. Most ADSL modems do not support multicasting. Example of IPR400 to 960SIP with Multicasting The combination of a 960SIP Console with one or more Omnitronics IPR400 devices presents an interesting configuration issue due to the following two limitations: a) 960 SIP Console only has a single RTP receive port number; and b) Each VoIP group on an IPR400 must have a unique RTP receive port number. This leads to a configuration issue for multiple 960SIP Consoles talking to an IPR400. To resolve this issue, it is necessary to configure the IPR400 to reflect received operator audio back to the 960SIP devices. This is achieved by setting up a VoIP conference on the IPR400 with the same multicast address and setting the transmit RTP port to the same value as the 960SIP receive RTP port this configuration uses multicast, so there it is no need for either the 960SIP or the IPR400 to be configured with the address of the other device. This configuration is implemented as follows: Multicast address for intercom between all of the 960SIP consoles. Multicast address for channel one on the IPR400. Multicast address for channel two on the IPR400. Multicast address for channel three on the IPR400. Multicast address for channel four on the IPR400. More than one 960SIP can be set up using this configuration. Table 5 lists the configuration for the IPR120 device in the 960SIP Console.

55 Figure 23. Basic SIP settings The IPR120 supports outgoing connections to Omnitronics products. From version 5.21 onwards, the IPR120 also supports the ability for a channel selector to join multicast groups without using SIP. See the section on multicast addressing for the advantages and disadvantages of multicast addressing. SIP UDP Port: The IP Port number used for the SIP protocol. This setting must match the setting used by all the devices the IPR120 will connect to. The value must be different to the port numbers used by the VoIP / RTP configuration. The default value of 5060 is the number assigned by the Internet standards body for SIP. Allowed values: 1025 to Default: 5060 User Name: The user name used in the SIP messages. Allowed values: String without any spaces or punctuation characters Default: ipr Enable status sounds: If enabled the IPR120 will play a distinctive sound when a SIP connection is made or disconnected.

Connection in progress ringing.wav Ring Tone Connection Failed failed.wav Busy tone Remote Device List The IPR120 can have up to 12 devices that it can connect to; each entry corresponds to a switch on the extended selector. SIP Address (URL): A SIP device has an identifier or Universal Resource Locator (URL) that is similar to a web address. The SIP URL is usually of the form sip:user@address:port, where user is the user name, address is the IP address of the device, and port is the UDP port number used for SIP. The port number is optional and will only be required if a port other than the standard port of 5060 is used. Some examples of SIP URLs are: sip:ipr@ sip:ipr@ipr110-plus-52a2112.local sip: @somevoipprovider.com It is not necessary to add the sip: to the address in the IPR120 configuration. If the address is invalid, the IPR120 will not be able to connect to the remote device. Default: Blank (not configured) RTP Address URI: This is for connections to multicast group addresses. The RTP has the form rtp:address:rtp_port where address is the IP address of the multicast group, and rtp_port is the RTP Port number (not SIP port number as for SIP URI). SIP Addressing Examples Here are a few examples of possible SIP addresses that could be configured in the IPR120 remote device table.

61 Statistics Shows details for network packets sent by this device. In the example shown on the previous page: RTP receive total packets is the total number of RTP packets received. RTP receive valid packets is the number of VoIP data packets received from the remote device. RTP receive invalid packets is the number of invalid VoIP data packets received from the remote device. RTP receive valid bytes is the total number of bytes received via RTP. RTP receive sequence errors is the number of sequence errors received. RTP receive packets too late indicates that a packet containing audio arrived at the IPR120 after it should have been played. If this value is large, it indicates excessive and changing network propagation delays. RTP receive STUN packets indicates the number of value STUN messages received. Some VoIP clients send STUN messages on the RTP port to help determine network configuration. RTP receive MULTICAST packets indicates whether a packet has been received from a multicast address. RTP transmit packets is the number of complete network (UDP) VoIP packets sent, but does not include other packets such as web server data or SNMP packets. RTP transmit bytes is the total number of data bytes sent, and includes the payload data, but it does not include the overhead due to Ethernet protocol. Current transmit bytes per second is an estimate of the current bandwidth usage for VoIP. This will display a non-zero value only if the IPR120 is currently transmitting audio information. Time since valid RTP packet is the time in milliseconds since the last RTP packet was received. RTCP receive total packets is the total number of RTCP packets received. RTCP receive valid packets is the number of valid RTCP packets received from the remote device. RTP receive invalid packets is the number of invalid RTCP packets received from the remote device. RTCP receive valid bytes is the total number of bytes received via RTCP. RTCP transmit packets is the number of complete network (UDP) VoIP packets sent, does not include other packets such as web server data or SNMP packets. RTCP transmit bytes is the total number of data bytes sent. This is the amount of payload data, it does not include the overhead due to Ethernet protocol. Time since valid RTCP packet is the time in milliseconds since the last RTCP packet was received. 960SIP Console Product Manual 51

62 Chapter 4 Source Name is the name/address of other IPR/VoIP devices communicating with this IPR120 (e.g., ipr100@ipr100-52a1215). Location is the location or name configured in the remote VoIP device. Firmware Information identifies the version of firmware in this IPR120. Source IP Address is the source IP address for this audio source, and is a numeric IP address. Source UDP Port is the UDP Port for this audio source. Destination IP Address is the destination IP address for this audio source, and is a numeric IP address. Received packets is the number of VoIP data packets received from the remote device. Duplicate packets is the number of packets that have been detected containing exactly the same data (network errors). Misordered packets is the number of packets that have arrived out of order, usually due to network delays. Packets arrived too late is the number of packets that have arrived after the point where they should have been played (network errors due to high latency). Current playout delay is the duration of audio (milliseconds) that the IPR120 currently holds in its jitter buffer. Current BUSY State is the current state of the Busy/Mute input. Current PTT State is the current state of the PTT output on this (local) IPR120 requested by the remote audio source. This will usually show whether the remote site currently has an active busy from a connected radio. 52 IPR120 Basic Configuration

Select the Advanced Mode, as shown in Figure 31. Figure 31. Changing to Advanced Mode 960SIP Console Product Manual 55

66 Chapter 5 Note The advanced and basic modes only affect the configuration display: selecting basic mode does not disable any advanced mode features or settings. Once the advanced mode has been selected, extra menu options appear on the left hand side of the interface and new options are available on all the existing pages. Advanced Network Settings In Figure 32, the advanced Network Settings page is displayed. You can see there are new options under the Advanced Settings and Dynamic DNS headings. Figure 32. Advanced Network settings 56 IPR120 Advanced Configuration

67 Advanced Settings Enable UPNP: Universal Plug and Play (UPNP) is a networking technology that allows devices to work together with fewer configurations. By enabling UPNP, the IPR120 will be displayed in the Network Neighborhood on computers running Microsoft Windows. Default: Enabled Enable network discovery using Bonjour/mDNS protocol: Multicast Domain Name System (mdns) is a technology that allow devices on a LAN or WAN network that supports multicast to provide a name to IP conversion without the need of a dedicated name server. By enabling this IPR devices can use names rather than IP address on local LANs. Unfortunately Microsoft Windows does not support mdns. Default: Enabled Domain Name System (DNS) Server 1: Primary Domain Name Server (DNS). The DNS is how an Internet address, such as is converted to a numeric address, like Consult your ISP or network administrator to discover what this address should be. In some cases the DNS server address is the same as the gateway address. This configuration item is only required when the VoIP remote address is going to be configured as a full Internet name, if the VoIP remote address is a numeric value or a local mdns address then this value can be left as the default value. Possible values: A valid numeric IP address in the form nnn.nnn.nnn.nnn where nnn is a number between 0 and A value of indicates that no DNS server is used. Default: (not used) Domain Name System (DNS) Server 2: Backup DNS server that is used in the event the primary DNS server is not available. Possible values: A valid numeric IP address in the form nnn.nnn.nnn.nnn where nnn is a number between 0 and A value of indicates that no DNS server is used Default: (not used) Enable Simple Network Management Protocol SNMP: SNMP provides a mechanism for reading status, setting values and reporting alarms. Currently the IPR120 only provides network statistics using SNMP. Default: Disabled SNMP Trap Destination: Sets the default destination for SNMP alarm or trap messages. Currently this item has no effect as SNMP traps have not been implemented. Default: (Disabled) Quality of Service: Differentiated Service Class: QOS Diffserv allows the IPR120 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 960SIP Console Product Manual 57

68 Chapter 5 Syslog host address: The IPR device can report debug and error information via a network protocol called SYSLOG. This is mainly used for debugging and diagnosing faults. This value is normally set to the default (not used). Possible values: A valid numeric IP address in the form nnn.nnn.nnn.nnn where nnn is a number between 0 and A value of indicates that no SYSLOG messages are used. Default: Dynamic DNS The Dynamic DNS area allows you to configure the DNS settings of the IPR120 and includes the following: Enable Dynamic DNS allows the device to track changes in its public IP address and to update the configured Dynamic DNS host accordingly. Additionally, it performs periodic Domain Name resolution of any configured remote domains and performs required adjustments when a remote end experiences a change in public IP address. Enabling this feature will decrease VoIP down-time when devices sit behind routers of which the IP address can change dynamically. The default is disabled. Note When enabling Dynamic DNS, ensure that the Domain Name System (DNS) Server 1 is configured to an actual DNS server. To enable period DNS resolution only, select this setting and leave all the following settings blank. Public IP Service 1 is a URL to a web service that returns the current public IP address of the requester. It must start with and it is best to verify this in a browser before transferring the URL to this setting. Service 1 will act as the primary web IP lookup. Leaving this field blank will disable determining the IPR120 devices public IP address. The default is Not Configured. Public IP Service 2 is similar to Public IP Service 1 except that this will act as the secondary web IP lookup if configured. It will only be used if Service 1 fails. The default is Not Configured. Device Domain Name is the fully qualified domain name of the device. It is this name that is used in all dynamic DNS updates when the device detects a change in the current public IP address. The default is Not Configured. Dynamic DNS Host Domain Name is the fully qualified domain name of the server hosting the Dynamic Domain Name service. The server must be the authority with which the Device Domain Name is registered. The default is Not Configured. Dynamic DNS Host Port is the HTTP port (usually 80) of the server hosting the Dynamic Domain Name Service. If port 80 is blocked by a local firewall and if the Dynamic Domain Name Host allows updates via another port, set this accordingly. The default port is 80. Dynamic DNS Host Authentication User Name is the user name required by the dynamic DNS Host for authentication in all updates. The default is Not Configured. Dynamic DNS Host Authentication Password is the password required by the dynamic DNS Host for authentication in all updates. The default is Not Configured. 58 IPR120 Advanced Configuration

69 Use the Public IP address for SIP determines whether the public IP address of the device will be used in all SIP conversations. If this setting is not selected, the private IP address will be used. This setting is not selected by default. Advanced SNMP Settings Select the SNMP Configuration page shown in Figure 33 to configure SNMP (Simple Network Management Protocol) settings. Figure 33. SNMP configuration page The SNMP configuration of the IPR120 includes the following parameters: Enable SNMP selects the Simple Network Management Protocol (SNMP) feature. SNMP provides a means to extract status information from the IPR120 through a network management system. The IPR120 provides several standard network statistics as well as the site monitoring and control I/O of the IPR120. If SNMP is not being used, this setting should not be selected. Read community is the SNMP authentication password needed to read (SNMP GET) values from the IPR120. The default community is "public". If left blank, the IPR120 will set this value to "public" when you save the configuration. 960SIP Console Product Manual 59

70 Chapter 5 Trap destination 1 and Trap destination 2 specify the IP address to which the IPR120 will send SNMP traps. This is also known as an SNMP trap sink address. Generally, it is the IP address of a machine that hosts network management software (NMS). The SNMP Trap destination can only be a valid static IP address. By default, the address is which disables SNMP traps. Enable VoIP statistic traps enables the VoIP SNMP Receive statistic reports section of the webpage, including the SNMP statistics interval parameter. Selecting this checkbox will enable the IPR120 to send a periodic SNMP trap (defined in the SNMP statistics interval) if either: a) The number of defined RTP Sequence errors is attained; or b) The number of defined RTP Packets too late is attained. Note The counters for each of these conditions will reset every time the SNMP statistics interval has been reached. SNMP statistics interval specifies in seconds when the IPR120 will send an SNMP trap if either: a) The number of defined RTP Sequence errors is attained or; b) The number of defined RTP Packets too late is attained. Note The counters for each of these conditions will reset every time the SNMP statistics interval has been reached. The default value is 900 seconds (15 minutes) VoIP receive sequence errors report threshold and VoIP receive packets too late report threshold define how many RTP sequence errors or how many RTP packets that arrive too late are permitted within the SNMP statistics interval. Generally, RTP sequence errors and RTP packets that arrive too late may occur during bad network conditions including slow networks, networks with high packet loss, networks with high packet jitter, or networks with many routers/switches between devices. The default value for these fields is 0 (disabled). 60 IPR120 Advanced Configuration

71 Advanced 960-Console Settings Figure 34 shows the configuration page for the 960 Console in advanced mode. The advanced settings are shown under the headings of Advanced Settings and BUSY Validation. For information about the basic settings, see section 960 Console Settings on page 40. Figure Console advanced settings Advanced Settings Busy Hold Time is the delay in milliseconds that the busy indication at the console will stay on after the remote radio has stopped sending its busy signal. This is mostly used as an indication to the operator as the audio will be sent to the console by default unless there is a PTT signal from the console to the IPR. For a short conversation, having a long busy-hold time will let the operator see which channel was active (in case the operator was not watching at the time). Allowed Values: milliseconds Default: 100 milliseconds Voice Activity Detection: Software detects when there is incoming audio. There are two uses for this information. One, data is only sent over the network when there is voice data (saving bandwidth). The second use is to generate a signal to drive the PTT relay at the remote end. Default: Enabled 960SIP Console Product Manual 61

72 Chapter 5 VAD hold/hang Time: This is how long the IPR120 continues to transmit data or hold PTT on after it detects that there is no activity. This is primarily used to ensure that the PTT remains active to keep the remote radio transmitting continuously. Allowed Values: milliseconds. Default: 100 milliseconds BUSY Validation The busy validation settings that you can configure include the following: Enable BUSY Validation allows the IPR120 to validate the busy input (debounce) to ensure it is present for the specified time. The default setting is busy validation disabled. BUSY Validation Time (milliseconds) is the duration (in milliseconds) for busy validation: the state of the busy signal will be ignored for this period, and no busy state or audio will be sent to the network. The allowed values are 0 to 1000 milliseconds. The default setting is 20 milliseconds. Enable Audio Delay option is used to impose an audio delay (of the same duration as the BUSY Validation Time) on the play out of received audio. This will ensure that the received audio is in sync with the validated busy output, as shown in Figure 35. Figure 35. Audio delay timing diagram 62 IPR120 Advanced Configuration

73 Advanced VoIP/RTP Settings Figure 36 shows the VoIP/RTP settings in advanced mode. The advanced settings are shown under the Advanced Settings heading. Figure 36. Advanced VoIP/RTP settings For basic settings, see section VoIP/RTP Settings on page 41. Transmit Codec: This is the method of encoding that is used to encode the audio data for transmission to the remote device. This setting only affects the audio sent. This IPR device will determine the type of Codec used by the remote device and decode the audio even if a different codec is used. Allowed Values: G.711 PCM mu-law, G.711 PCM A-law, GSM; Default: G.711 PCM mu-law Note NOTE: Different versions of IPR devices and VoIP phones can support different codec types, The IPR120 devices can also decode: G , G726-25, G and ADPCM-DIVI(32k) data streams. The IPR120 does not support G.729 or G codecs. IP Time To Live (TTL): This determines the number of network routers that will pass on the data packets from this unit. This value limits how far the message will be sent. 960SIP Console Product Manual 63

74 Chapter 5 Typically as a router passes on a data packet, it will decrease the TTL information in the data packet, once the TTL reaches zero, the message will no longer get forwarded. Allowed values: 1 255; Default: 128 When using multicasting, the TTL value indicates the scope or range in which a packet may be forwarded. When configuring an IPR device to use multicasting, it is important to consult with the IT department that manages the network infrastructure to make sure an appropriate value is used. Allowed Values: TTL=0 is restricted to the same host TTL=1 is restricted to the same subnet TTL=32 is restricted to the same site TTL=64 is restricted to the same region TTL=128 is restricted to the same continent TTL=255 is unrestricted Minimum jitter buffer size (milliseconds): If the IPR120 is used on a network where 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 the received audio will be delayed. Allowed Values: ms; Default: 20ms. Maximum jitter buffer size (milliseconds): This sets the maximum acceptable audio delay, for received audio. The software will automatically adjust the delay (depending on network conditions) to be as small as possible, thus reducing the received audio delay to the minimum that the network can support. The maximum jitter buffer size must be greater than or equal to the current minimum jitter buffer size. Allowed Values: ms; Default: 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 on both devices that have a VoIP link is established. If multicasting is used, all devices in the multicast group must have this parameter set identically. Reducing the value of this parameter has the effect of reducing the time in detecting a link disconnection with the associated disadvantage of increasing the required Ethernet bandwidth. Alternatively, increasing the value of this parameter reduces the required Ethernet bandwidth and increases the time to detect a link disconnection. An increased RTCP interval may be useful in data bandwidth critical application such as a VoIP link through the 3G mobile phone network. The allowed values are 1 to 120 seconds. The default value is 5 seconds. 64 IPR120 Advanced Configuration

75 BUSY/PTT periodic transmit disable option disables the periodic transmission of Busy and PTT status information. In normal operation, the IPR device will send the state of the Busy input and Push-To-Talk output to all connected devices to ensure that the current state is always correct. However, in some scenarios, such as expensive satellite IP links, it may be desirable to disable this feature. In this case, Busy and PTT changes are only sent when the state of the input or output actually changes. BUSY/PTT periodic transmit time determines the period (in seconds) at which the IPR120 sends the state of its Busy input and Push-To-Talk output to connected VoIP devices. Encryption: The IPR120 can encrypt the network data so that a third party is unable to intercept and listen in to conversations. Using an encryption algorithm and enabling encryption will allow the IPR120 to encrypt all voice and control data. The IPR120 can provide two algorithms. The DES algorithm is an older less secure algorithm with a secret key that is 56 bits long. The AES algorithm is a newer algorithm that has a key length of 128 bits, making it more secure. Due to export restrictions only devices with DES encryption can be exported from Australia. As a result international IPR120's only have the DES encryption option. Allowed Values: Encryption Disabled, Encryption Enabled (AES128) or Encryption Enabled (DES); Default: Encryption Disabled. Encryption Key: This string is used to generate an encryption key. This ensures that no third party can decrypt the VoIP data. If this field is left blank the default encryption is used. This ensures backward compatibility with earlier versions of the IPR120 firmware (version 1.24 and earlier). Note If encryption is enabled then all communicating IPR devices must have encryption enabled AND must be configured with the exact same encryption type and encryption key otherwise the IPR devices will not be able to communicate and the VoIP LED indicator will not illuminate. Busy Channel Lockout Enable: When this option is checked, it will prevent the IPR120 from transmitting while it is receiving an active busy on any channel in foreground or background. This option should be enabled in configurations where multiple IPR120 are connecting to a single remote IPR device. 960SIP Console Product Manual 65

76 Chapter 5 Advanced Selcall/DTMF Settings The IPR120 supports SELCALL and DTMF by detecting the tone, encoding it as a data packet, and sending it to a remote device. This enables SELCALL and DTMF to be sent on links with GSM or other compression codec. Figure 37 shows the settings for the Selcall and DTMF these settings are not available in basic mode. Figure 37. Advanced selcall/dtmf settings 66 IPR120 Advanced Configuration

77 Selcall and DTMF settings are generally only used when the IPR120 and 960ES are paired with an Omnitronics 960CSD console. The 960CSD enables a user to receive and transmit SELCALL/DTMF strings using a keypad and LCD screen. General Tone Transmit Level: This is the output level for transmitting both SELCALL and DTMF tones to locally installed equipment. This level does not affect the audio transmit level and is not in turn affected by the audio transmission level. Allowed values: -10 db to +10 db; Default: 0 db Lead In Delay (10 x milliseconds): The IPR120 will assert the PTT relay for this length of time before starting to transmit a SELCALL or DTMF tone. This is to ensure the radio is on and transmitting correctly before the tone is transmitted. Allowed values: 2 to 255 (20 milliseconds to 2.55 seconds); Default: 100 (1 second) Lead Out Delay (10 x milliseconds): The IPR120 will hold the PTT relay on for this length of time after completing a DTMF or SELCALL tone. This is to ensure the radio does not turn off before the whole tone has been received. Allowed values: 2 to 255 (20 milliseconds to 2.55 seconds); Default: 50 (500 milliseconds) DTMF DTMF Detection: DTMF Detection: Enables local detection of DTMF. If this is selected, the IPR120 will locally listen for and decode DTMF tones and send them to and from the paired 960 console. When it receives a valid DTMF tone from a connected 960 console, it will packetize the tone and send it to the remote device (such as an IPR110Plus). At the remote device, the data packet will be received and the remote device will generate the corresponding DTMF tone sequence. Default: Disabled DTMF Tone Period (in milliseconds): The Tone and Silence periods are used for generating DTMF signals. It may be necessary to use the 100 millisecond option with some equipment that has slow detection periods. Allowed values: 100ms or 50ms; Default: 100ms SELCALL (Selective Calling) SELCALL Detection: Enables local detection of SELCALL. If this is selected, the IPR120 will locally listen for and decode SELCALL tone sequences and send them to and from the paired 960 console. When it receives a valid SELCALL sequence from a connected 960 console, it will encode it as a data packet and send it to the remote device (such as an IPR110Plus). At the remote device, the data packet will be received and the remote device will generate the corresponding SELCALL sequence. Default: Disabled SELCALL Scheme: This specifies the type of SELCALL scheme being used. Allowed values: The supported SELCALL schemes are EEA, ZVEI-I, ZVEI-II, ZVEI-III, PZVEI, CCIR,EIA and DZVEI; Default: CCIR 960SIP Console Product Manual 67

78 Chapter 5 Number of Tones: The number of tones and gaps in a valid SELCALL sequence. Allowed values: 1 20; Default: 5 SELCALL Tone Period (milliseconds): The time duration of each tone in the sequence. Allowed values: 20 to 100ms; Default: 20ms Tone Position and Type: For each configured tone position it can be configured to detect a particular tone or silence duration. Possible values are Tone: Normal Period: A tone that is equal in duration to the configured tone period Tone: Extended Period: A tone that is twice the duration of the configured tone period Silence:Normal Period: A silence that is equal in duration to the configured tone period Silence:Extended Period: A silence that is twice the duration of the configured tone period There are some extra rules that the configuration interface enforces, these are: First and last positions must be a tone An extended tone period can only be configured in a position after a silence period. Examples SELCALL Configurations Example 1: Tone scheme is CCIR, Five Tones with period 20 milliseconds. Example 2: Tone Scheme EIA, Tone Period 40 milliseconds, 4 Tones with Status Tone (5 Tones total) and Gap. Status and Gap double width. 68 IPR120 Advanced Configuration

79 Example 3: Tone Scheme CCIR, Tone Period 33 milliseconds. Four tone source address, gap, four tone destination address, gap and then two tone status. 960SIP Console Product Manual 69
