About this Manual Overview The DRG-Series of Digital Radio Gateway devices supports many digital-radio functions. However, not all digital radios support all of these functions. Hence, the DRG is programmed at the factory for a particular digital-radio interface depending on the type digital radio you intend to use. This publication supplements the information in the DRG-Series Product Manual supplied with your DRG product. The information presented covers the configuration and diagnostics of the DRG implementing the Tait P25 Computer Controlled Data Interface (CCDI) protocol. This is a Tait proprietary command protocol used for communicating with the TM9400 series via asynchronous serial ports. This implementation is known as Tait P25 CCDI (Tier-2) and is compatible with the Tait TM9400 series mobile radio. Intended Audience This manual is intended for technical support personnel, system and network administrators, who install, configure and maintain the DRG. Related Documentation In addition to this supplement, the following provide related information: DRG100 Digital Radio Gateway Product Manual (MNL-00106) The following documents define the protocols implemented, which are all available as RFC documents from the Internet Engineering Task Force (IETF): RFC3550 - RTP: A Transport Protocol for Real-Time Applications RFC3551 - RTP Profile for Audio and Video Conferences with Minimal Control RFC2833 - RTP Payload for DTMF, Telephony Tones and Telephony Signals RFC3261 - SIP: Session Initiation Protocol vii

Chapter 1 Configuration This chapter discusses the configuration of the DRG implementing the Tait P25 CCDI (Computer Controlled Data Interface) protocol. All web page images included in this supplement are specific to the DRG100 device; however, the web pages for the other DRG devices will be similar. This chapter includes the following sections: Viewing the System Status Digital Radio Configuration on page 3 Viewing the System Status Select System Status on the menu to display comprehensive status information about your DRG. The information displayed on this page is read-only so you cannot make any changes. It shows the version information for both the hardware and the firmware used in the DRG together with its operational status. Figure 1 shows an example of the System Status page for CCDI digital-radio interface logged in under the administrator account if you are logged in under the technician or limited-user account, the information displayed will be the same; however you will not see as many menu items. Most of the information shown on this page is the same for all digital-radio interfaces supported by the DRG for further information about these values, refer to the DRG-Series Product Manual. Information specific to the Tait CCDI appears under the section Digital Radio: TAIT CCDI Status (see Digital Radio: TAIT CCDI Status on page 3). Tait P25 CCDI Supplement 1

Chapter 1, Configuration Figure 1. System status page for Tait CCDI 2 DRG-Series Digital Radio Gateway

Digital Radio: TAIT CCDI Status Figure 2 shows the typical interface information you will see for a DRG implementing the Tait P25 CCDI protocol. This additional information appears under Digital Radio: TAIT CCDI Status. Figure 2. CCDI serial connection status The information displayed under Digital Radio: TAIT CCDI Status includes the following information: Serial Connection shows whether the DRG is able to communicate with the Tait TM9400 series radio via the serial port using the CCDI protocol. Connected Disconnected DRG is able to communicate with the Tait TM9400 series radio via the serial port using the CCDI protocol. DRG is not able to communicate with the Tait TM9400 series radio. Check your serial port connection. If the status shows "Disconnected", the DRG will not be able to issue commands to the Tait TM9400 series radio. Digital Radio Configuration Select the Digital Radio menu to display the Digital Radio configuration page. This page allows you to configure the interface settings that affect the operation of the digital radio attached to the DRG product. Figure 3 shows an example of the Digital Radio Configuration page when logged in under the administrator account in basic mode the same settings will also appear in advanced mode. Some digital-radio settings are common to all digital-radio interfaces. These common settings are located on the Digital Radio tab and are discussed in the section Common Digital Radio Settings on page 5. The CCDI settings appear on the TAIT CCDI Settings tab and are discussed in the section Tait CCDI Settings on page 8. Tait P25 CCDI Supplement 3

Chapter 1, Configuration Figure 3. Digital radio configuration page for common settings Omnitronics Gateway Interface The Omnitronics Gateway Interface includes only the following setting: TCP Port is the port used by the DRG for incoming TCP connections the DRG listens on this port for incoming connections from Omnitronics Dispatch Consoles such as RediTALK and Alto. 4 DRG-Series Digital Radio Gateway

Common Digital Radio Settings The settings displayed on the Digital Radio Settings tab include many settings common to all digital-radio interfaces; however, whether all of these are used depends on the digital-radio interface supported by your DRG. The DRG supports many digital-radio functions, but not all digital radios support all of these functions. Therefore, the DRG is programmed at the factory for the digital-radio interface that you intend to use. This section of configuration settings controls whether a specific capability is published to the DX-Altus Server, and therefore visible on an Omnitronics Dispatch Console. The settings in this section include the following: Disable Channel Change option allows you to disable the capability to change the channel on the radio (this capability will be preconfigured by software provided by the radio manufacturer). Disable Call Alert option disables the ability for the console operator to send an alert to another radio. A call alert allows the console operator to send an alert to another radio requesting that the radio operator call back the console operator (the radio operator acknowledges the alert by pressing PTT). Disable Individual Call option disables the ability to initiate an individual call from a console. Disable Individual Call Timeout option disables individual-call timeouts. Individual Call Timeout is the time (in seconds) that the DRG will wait for individual-call activity before it cancels the individual call and reverts to default call mode. This timeout is only used when the Disable Individual Call Timeout option above is not selected. Disable Group Call option disables the ability to initiate a group call from a console to a group of radios. Disable Group Call Timeout option disables group-call timeouts. Group Call Timeout is the time (in seconds) that the DRG will wait for group-call activity before it cancels the group call and reverts to default call mode. This timeout is only used when the Disable Group Call Timeout option above is not selected. Disable All Call Timeout option disables the All Call timeout and allows the console operator to immediately setup a new call without the need to wait or cancel the All Call. If the timeout is enabled, it implies that the console operator will have to either first cancel the call (only applicable to P25) or wait for the timeout to expire (P25, MOTOTRBO, and IDAS). Tait P25 CCDI Supplement 5

Chapter 1, Configuration All Call Timeout is the time (in seconds) that the DRG will wait for all call activity to cease before it reverts to default call mode. This timeout is only used when the Disable All Call Timeout option is not selected. Call Setup Timeout is the timeout applied to call setup when the console operator does not PTT within a reasonable time (see Figure 4 on page 7). The console operator can use Alto to send a request to setup a specific call type. If a PTT is received within the specified time window, the DRG will setup this call type. However, if no PTT is received and the timer expires, the DRG will revert to its default call state. If an incoming call is received during this timeout window, the DRG will accept the incoming call and it will void the operator s original request. In this case, the operator will have to request the call type again after the incoming call ends. Disable Emergency option disables access to the Emergency feature from the DRG and any connected dispatch consoles such as Alto. Disable GPS prevents GPS coordinates generated by the radio from reaching connected dispatch consoles such as Alto and RediTALK, which in turn prevents the connected radio from appearing on the GPS map. Disable Radio GPS Request Update prevents connected dispatch consoles such as Alto and RediTALK from requesting the current GPS coordinates of the connected radio. Disable Radio Status Message disables access to the Status Message feature from the DRG and any connected dispatch consoles such as Alto. Disable Poll Radio Status disables access to the Poll Radio Status capability from the DRG and any connected dispatch consoles such as Alto. Default Call Type defines the type of call made by the DRG once it reverts to default call. The options available are: All Call, and Group Call (see Digital Radio Call on page 12). Defaults to All Call. Default Group determines the group to be called. Ranges from 1 to 1,000,000. Defaults to 1. Each of the following options disables a specific remote radio command. This also affects the Diagnostics page: when you select an option, the corresponding command will not be available under the Remote Radio Commands section (see Remote Radio Commands on page 14). Disable Radio Check disables access to the Radio Check capability from the DRG and any connected dispatch consoles such as Alto. 6 DRG-Series Digital Radio Gateway

Disable Stun Radio disables access to the Stun Radio capability from the DRG and any connected dispatch consoles such as Alto. Disable Revive Radio disables access to the Revive Radio capability from the DRG and any connected dispatch consoles such as Alto. Call timeouts are illustrated in the timing diagram depicted in Figure 4 this applies to the digital-radio interfaces. This group of timeouts follows the same principle but each call type (IND, GRP, ALL) can be configured independently. The purpose of the timeout is to maintain the call type and recipient during overs until there is no activity (BUSY/PTT) within a specified time window. Figure 4. Digital radio timing diagram showing call timeouts This timeout can be enabled or disabled for each call type. If disabled, the DRG will apply the default call configuration (All Call) as soon as PTT/BUSY is cleared. If the timer is not disabled, the DRG will maintain the call type and recipient and reset this timer after every over. If the timer is allowed to expire (no one pressed PTT within the timeout), the DRG will revert to the default call type. This implies that the next PTT will then setup an All Call. Tait P25 CCDI Supplement 7

Chapter 1, Configuration If the timer expires while a BUSY/PTT is active, the timer will restart. Keep in mind that the radio itself may have similar timers that cannot be interrogated by the firmware, and if these timers clash with those on the DRG, the DRG will not behave as expected. It is recommended that you always set the DRG timers greater than the actual radio timers. Tait CCDI Settings Figure 5 shows the settings for a DRG implementing the Tait CCDI protocol these settings appear on the TAIT CCDI Settings tab are the same in both basic and advanced modes. Figure 5. Settings for TAIT CCDI 8 DRG-Series Digital Radio Gateway

Serial Port Settings Baudrate is the RS-232 data rate used by the Tait TM9400 series radio. The status of the serial connection may be viewed on the System Status page under the heading Digital Radio: Tait CCDI Status (see Digital Radio: TAIT CCDI Status on page 3). Important This setting must match the data rate programmed into the Tait TM9400 series radio otherwise the serial connection will fail. Tait CCDI Radio Settings Radio Zone Number is the zone number the Tait TM9400 radio uses to make calls. Important This setting must match the Radio Zone Number programmed into the Tait TM9400 series radio. Volume Enable and Volume Level allow the DRG to control the volume of an external speaker connected to the Tait TM9400 series radio. The allowed volume range is 1 to 25 where 25 is the loudest. Tait P25 CCDI Supplement 9

Chapter 2 Diagnostics and Statistics In this chapter, we discuss the diagnostic features of the DRG and how to use these features with the Tait P25 CCDI (TM9400 series) digital-radio interface. This chapter includes the following sections: Digital Radio Diagnostics Statistics on page 16 Digital Radio Diagnostics The DRG provides a separate diagnostics page for performing basic diagnostics and troubleshooting of the digital-radio interface. Select Digital Radio under the Diagnostics menu to view the Digital Radio Diagnostics page. Figure 6 shows the corresponding page for Tait P25 CCDI. Some of the diagnostic sections shown on this page may or may not be displayed depending on whether its corresponding disable setting on the Digital Radio configuration page is selected. For example, if the option to disable Radio Status Messages is selected, the Radio Status Message section will not be shown. For further information about these settings, refer to Common Digital Radio Settings on page 5. Tait P25 CCDI Supplement 11

Chapter 2, Diagnostics and Statistics Figure 6. Viewing the digital-radio diagnostics page for P25-DFSI Digital Radio Call The Digital Radio Call section allows you to perform several diagnostic tests associated with Call Setup and Busy Activation, as discussed below. Call Setup Use this section to set up and test a particular call type. 12 DRG-Series Digital Radio Gateway

Call Type determines the type of digital-radio call to make. Depending on the call type, it may occur as soon as the user clicks the Setup Call button or it may occur on the first Push-To-Talk request after the Setup Call button has been pressed. The options available for the call type will depend on the capabilities and configuration of the radio but may include the following options: Default Individual Call Group Call All Call Call Alert The next radio call will be the default for this radio. This is a call to a single radio. This is a call to all radios in a particular group. This is multiple calls to all radios on the network. This sends a call alert to a single radio. This is sent immediately without waiting for the next Push To Talk request. Some of these call types may not be available depending on whether the corresponding call-type option is disabled on the Digital Radio page. For further information about these options, refer to Common Digital Radio Settings on page 5. Destination: Radio ID or Group ID is the unique identity of the radio, or the group of radios, you want to call. To set up a particular call to a radio, or group of radios, select the call type from the Call Type dropdown, type the numerical destination into the Destination: Radio ID or Group ID text box, and then click Setup Call to send the request to the radio this may occur as soon as you click the button or it may occur on the first Push-to-Talk. Once the request is sent, the call type should appear next to Call Type under the Radio Status section (see Radio Status on page 15). Busy Activation Toggle Busy allows you to simulate and test the busy signal on this DRG. This is useful when you suspect the busy signal from the repeater/base station is not detected. To simulate and test the busy signal, click Activate Busy. This should send a busy indication to the dispatch console so you can check whether the busy indication operates as expected. You should also see the busy indication under Radio Status section (see Busy radio status on page 15). Click the button again to terminate the test. Tait P25 CCDI Supplement 13

Chapter 2, Diagnostics and Statistics Channel Change The Channel Change section may not be visible depending on whether the option to disable channel change is selected (see the Disable Channel Change option on page 5). This section includes the following setting: Channel Number is the number of the channel on the radio to which you want to change. To send the channel-change request to the radio, type the channel number into the Channel Number text box, and then click Set Channel. Radio Status Message The Radio Status Message section allows you to send a status message to the specified radio. This section may not be visible depending on whether the option to disable radio status messages is selected (see the Disable Radio Status Message option on page 6). This section includes the following settings: Message Type is the type of message you want to send and can be either Individual or Group. Destination: Radio or Group ID is the identity of the radio, or group of radios, to which you want to send the status message. Status Message Number is the number of the status message you want to send to the radio. Select the type of message from the Message Type dropdown list. Type the radio identity into the Destination: Radio or Group ID text box, type the number of the status message into the Status Message Number text box, and then click Send Status to send the status message to the radio. Remote Radio Commands The Remote Radio Commands section allows you to send commands to the remote radio. This section may or may not be visible depending on what options are selected on the Digital Radio page to disable remote radio commands (see Disable Poll Radio Status, Disable Radio Check, Disable Stun Radio, and Disable Revive Radio options on page 6). Command is the command you want to send to the radio and can be one of those listed below. The commands available will depend on the capabilities and configuration of the radio: 14 DRG-Series Digital Radio Gateway

Poll Radio Status Radio Check Stun Radio Revive Radio Sends a message to a radio to get its current status. The status is a numeric value that indicates the current activity the radio user is doing. Sends a message to a particular radio ID to determine whether the radio is powered on and receiving. Sends a message to a radio terminal that will temporarily disable the radio. Sends a message to a radio terminal that has previously been stunned to revive the radio. Some of these commands may not be available depending on whether the corresponding command option is disabled on the Digital Radio page. For further information about these options, refer to Common Digital Radio Settings on page 5. Destination Radio ID is the identity of the radio to which you want to send the command. Select the command from the Command dropdown list, type the numeric radio identity into the Destination: Radio ID text box, and then click Execute to send the command. Radio Status The Radio Status section displays the status of the digital radio connected to the DRG. The status depends on the radio functionality and firmware, and may include the following: Communication Status indicates the current communication state of the link between the DRG and the connected digital radio. It shows OK if the communication link is good or failed if the link is not working Push To Talk indicates whether the radio is currently transmitting (ON) or not transmitting (OFF). Busy indicates whether the radio is currently receiving (ON) or not receiving (OFF). Call Type indicates the current active call type, which can be: All Call, Group Call, or Individual Call. Radio ID indicates the identity of the radio receiving or transmitting. Channel Number indicates the currently selected radio channel. Group ID indicates the currently active group (transmitting or receiving). Tait P25 CCDI Supplement 15

Chapter 2, Diagnostics and Statistics Statistics The Statistics page is displayed when you select Statistics under the Diagnostics menu. The page is the same in both basic and advanced modes, and provides comprehensive statistics of the DRG operation. Figure 7 shows the page for the DRG P25-DFSI you may not be able to display the entire page in your web browser like the examples shown here, but you can scroll the page contents up and down using the scrollbar. Figure 7. Viewing the Statistics page for Tait CCDI 16 DRG-Series Digital Radio Gateway

Omnitronics RTP Statistics Under Statistics on this page, you can view the various statistic counters and other useful information, which includes the following: RTP receive total packets is the total number of RTP packets received. RTP receive valid packets the number of valid RTP packets received from the remote device. RTP receive invalid packets is the number of packets received that do not contain valid RTP formatting. If this number is very large, it may indicate that this port is being used by some other network protocol. RTP receive valid bytes is the total number of bytes received via RTP. RTP receive sequence errors indicates the number of packets that either were not received or which arrived out of order. If this value is large, it indicates that the network is experiencing packet loss or excessive network jitter. RTP receive packets too late indicates that a packet containing audio arrived at the DRG 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 DRG is currently transmitting audio information. Time since valid RTP packet is the time in milliseconds since the last RTP packet was received. RTP Payload 8 is the total number of RTP packets with a payload number of 8. Tait P25 CCDI Supplement 17

Chapter 2, Diagnostics and Statistics RTP Payload 97 is the total number of RTP packets with a payload number of 97. 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. RTCP receive invalid packets is the number 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 RTCP packets transmitted to the remote device. RTCP transmit bytes is the total number of bytes transmitted via RTCP to the remote device. Time since valid RTCP packet is the time in milliseconds since the last RTCP packet was received. No Active Connections is displayed when there are no active RTP connections (excluding itself). 18 DRG-Series Digital Radio Gateway
