7 Introduction About this Supplement The DRG-Series of Digital Radio Gateway devices supports many digitalradio functions. However, not all digital radios support all of these functions. Hence, the DRG is programmed at the factory for the digitalradio interface you intend to use. This document supplements the information in the DRG-Series Product Manual supplied with your DRG. The information presented covers the configuration and diagnostics of the DRG implementing the DMR-AIS (Digital Mobile Radio Application Interface Specification) IP protocol for Tier-2 and Tier-3. This implementation is known as DRG DMR-AIS IP. Firmware Compatibility The DRG100/DRG200i firmware is compatible with the DMR-AIS (Tier-2 and Tier-3) specification and comprises several flavours as listed below.

11 Configuration This section discusses the configuration of the DRG implementing the DMR-AIS IP interface. 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 section includes the following topics: Viewing the System Status Digital Radio Status and Statistics on page 6 Digital Radio Configuration on page 8 Viewing the System Status Select System Status on the menu to display comprehensive status information about your DRG device. All the values displayed on this page are read-only so you cannot make any changes to these values. This page displays in your web browser each time you log in to the configuration interface. 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 when 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 digitalradio interfaces supported by the DRG for further information, refer to the respective DRG-Series Product Manual for your DRG device. DMR-AIS IP Supplement 5

12 The information that is specific to the DMR-AIS interface appears under Digital Radio: DMR-AIS Status (see Digital Radio Status and Statistics on page 6). Figure 1. System status page for DMR-AIS interface Digital Radio Status and Statistics Figure 2 shows the typical interface information you will see for a DRG device implementing the DMR-AIS interface. 6 Configuration

13 Figure 2. Digital radio status and statistics for DMR-AIS interface Digital Radio: DMR-AIS Status Fleet Address parameter is only shown if the Enable Fleet Numbering option is enabled. The format of the fleet address depends on the Fleet Numbering Scheme selected and the configured DMR-AIS address. If MPT1343 numbering is used, the value displayed will be the configured Fleet Prefix, Fleet Individual Number, and the calculated Unit number for this DRG. If MPT1327 numbering is used, the value displayed will be the configured Fleet Prefix and the calculated Unit number for this DRG (see Fleet Numbering on page 18). SIP Connection shows the status of the SIP connection to the radio system controller. This will appear as either Not Connected or Connected. Registration Status shows the status of the last attempt to register with the DMR-AIS radio system controller. If the registration was successful, this will show Registration Status:200, OK. If it was not successful, it will show the SIP error status. Possible values include: 200 OK Registration successful 403 FORBIDDEN The password configured in the DRG does not match the value in the radio system controller. 404 NOT FOUND The user name configured in the DRG does not match the value in the radio system controller. 408 REQUEST TIMEOUT The radio system controller is not responding. DMR-AIS IP Supplement 7

14 Current Node Address shows the SIP URI used to connect with the DMR-AIS controller. The DRG can be configured with up to ten DMR-AIS controller addresses. Status shows the status of the last DMR-AIS call. This includes normal operations and error conditions. Possible values include: Registering with DMR AIS Server, DMR-AIS Call Ended, DMR- AIS End Call, Register Group XXXX, Unregister Group, and Idle. Call Status shows the one of the following: No call active, Individual call, Radio ID nnn, or Group Call, Group ID gggg. Registered Group shows the currently registered group. If no group is registered, this shows None. GPS Status shows whether or not the DRG has logged into the GPS server. DMR-AIS RTP Statistics Time since valid RTP packet shows the time since an RTP packet has been received from the DMR AIS system. Digital Radio Configuration Select Digital Radio on the menu to display the Digital Radio Configuration page, as shown in Figure 3 (the Digital Radio tab is selected by default). Use this page to configure the DRG capabilities and how the digital-radio interface operates. The settings on this page are common to all digital-radio interfaces, and are the same in both Basic and Advanced modes (see Common Digital Radio Settings on page 8). The settings applicable to the DMR-AIS IP interface appear on the DMR-AIS Settings tab (see DMR-AIS Settings on page 14). Common Digital Radio Settings The settings on the Digital Radio page are common to all digital-radio interfaces, and are discussed below. 8 Configuration

15 Figure 3. Digital Radio configuration page for common settings Omnitronics Gateway Interface The information displayed under Omnitronics Gateway Interface includes only the following setting: TCP Port Number is the port used by the DRG for incoming TCP connections the DRG acts as a TCP server and will accept incoming connections on this port from other Omnitronics devices. Digital Radio Settings The settings under Digital Radio Settings configure the digital-radio capabilities of the DRG, and determine what capabilities are published to Omnitronics Dispatch Consoles, such as Alto and RediTALK-Flex, and include the following: DMR-AIS IP Supplement 9

16 Disable Channel Change option disables the capability for the console operator to change the channel on the radio (this capability in the radio must be configured 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 the default call type. This timeout is only used when the Disable Individual Call Timeout option is not selected. Enable Confirmed Individual Call option allows the console operator to pick up (confirm) an incoming Individual Call. Confirmed Individual Call Timeout is the time (in seconds) an incoming Individual Call will time out and be cancelled when not confirmed (picked up) within this timeout. Disable Group Call option disables the ability to initiate a group call from a console to a group of radios. Disable Group Call Broadcast option disables the ability to send a Group Call Broadcast. 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 the default call type. This timeout is only used when the Disable Group Call Timeout option is not selected. Disable Group Registration option disables the group registration. Disable All Call option disables the ability to send an All Call request. All Call Group Address is the DMR All Call group Address. Disable All Call Timeout option disables the timeout for All Calls. 10 Configuration

17 All Call Timeout is the time (in seconds) that an All Call will time out and be cancelled when no activity is detected within this timeout. Call Setup Timeout is the timeout when the operator initiates a call setup, but does not PTT within a reasonable time (see Figure 4). The console operator can request a specific call type to be set up by selecting a Group Call or Individual Call for the particular channel. If the operator asserts PTT within the specified time, the DRG will setup this call type; otherwise, the DRG will revert to its default call state. If an incoming call is received during this timeout, the DRG will accept the incoming call and it will terminate 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 prevents the DRG, and any connected dispatch consoles, from using the Emergency capability. Disable Emergency Clear option disables the Emergency Clear capability. Disable Text Messaging option prevents the DRG, and any connected dispatch consoles, from sending a text message to a specific radio or to a group of radios. Disable GPS option disables the ability to use the location data received from remote radios. Default Call Type selects the default call type to use, which can be None or Group Call. Default Group specifies the group number to call when the Default Call Type is set to Group Call. Ranges from 1 to 1,000,000. Defaults to 1. Enable Radio Linking option enables the radio-linking capability, and when enabled on at least two channels, and is supported by your DRG firmware on these channels, it allows a operator to link audio between these channels using the link menu. When audio is linked, an incoming busy from a field radio on one of these linked channels will be sent as a default call PTT on the other linked channel and vice-versa. Enable Radio Patching option enables the Radio Patching capability that dynamically forwards incoming radio audio to other network devices. DMR-AIS IP Supplement 11

18 Remote Radio Commands 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 31). Disable Radio Status Message option disables the Radio Status Message capability in the DRG, and prevents any connected dispatch consoles from requesting the radio s status using this capability. Disable Radio Check option disables the Radio Check capability in the DRG, and prevents any connected dispatch consoles from using this capability. Disable Stun Radio option disables the Stun Radio capability in the DRG, and prevents any connected dispatch consoles from sending the Stun Radio command to the digital radio. Disable Revive Radio option disables the Revive Radio capability in the DRG, and prevents any connected dispatch consoles from sending the Revive Radio command to the digital radio. Disable Monitor Radio option disables the Monitor Radio capability, which is used to monitor a remote radio (tier-2 only). Call Timeouts Call timeouts are illustrated in the timing diagram depicted in Figure 4. The purpose of a call timeout is to ensure the connection is maintained during overs so that the call is not prematurely disconnected. If no further activity (BUSY/PTT) is detected during the time specified by the call timeout, the call will automatically disconnect. Note The radio system will have similar call timeouts. If the radio system determines that a call has been completed due to a timeout, it will end the call and notify the DRG. It is advisable that you always set the DRG timeouts greater than the actual radio timeouts. 12 Configuration

19 Figure 4. Digital radio timing diagram showing call timeouts The timeouts for each call type (IND, GRP, ALL) can be configured independently, and can be enabled or disabled as required. If the timeout associated with a particular call is not disabled, the DRG will maintain the connection (call type and recipient) and reset the call timeout after each over. When a call timeout occurs (no one pressed PTT within the timeout), the DRG will revert to the default call type. If the timeout associated with a particular call is disabled, the DRG will apply the default call configuration (All Call) once PTT/BUSY clears. DMR-AIS IP Supplement 13

20 DMR-AIS Settings Select the DMR-AIS Settings tab to display the DMR-AIS settings, as shown in Figure 5. This page is the same in Basic and Advanced modes. Figure 5. Digital radio configuration page for DMR-AIS When used with several nodes, the DRG DMR-AIS firmware will only change nodes when it detects a communication failure with the current primary node. The timing of this will depend on the Registration Expiry and the DMR-AIS OPTIONS keep-alive message interval. Note SIP provides a retry mechanism for messages and it generally takes about 32 seconds for a message to fail. So if the DMR-AIS SIP options messages are sent at 10-second intervals, it will take up to 42 seconds to detect that the communication link has failed and then attempt to communicate with the next node! 14 Configuration

21 DMR-AIS Tier selects the mode of operation of the radio node or base station with which the DRG device communicates. You can select the following modes of operation: Tier 3 for trunked mode systems and Tier 2 for conventional mode systems. This setting affects the supported features that will be available from the console. Set this to match the mode of the connected radio system. DMR-AIS Compatibility Mode selects the compatibility mode to use and configures the DRG for compatibility with proprietary features and different levels of the DMR-AIS standard. The supported options are DMR AIS Standard V1.0, Simoco Compatibility Mode, and Kenwood Compatibility Mode. You should select Simoco Compatibility Mode when connecting to a Simoco AIS Gateway. DMR-AIS Tier 2 Slot selects which slot to use for all calls. This setting is only used with Tier 2 (conventional) radio systems. This setting should be left as Tier2 Slot Not Specified for most radio systems. Currently, it is only used with Harris DMR-AIS Tier-2 radios and Kenwood DMR-AIS Tier-2 radios. Transmit Gain is the gain applied to the audio that the DRG sends to the DMR-AIS base station and only applies to the digital audio path. The gain value ranges from -10dB to +10dB. Receive Gain is the gain applied to the digital audio that is received from the DMR-AIS base station and sent to the console or other gateways. This gain value ranges from -10dB to +10dB. DMR-AIS SIP Port Number is the port used for SIP connections to the DMR-AIS system radio controller. The allowed values are 1025 to The value of 5060 is the port assigned by the Internet standards body for SIP, however, this setting must be set to a different port, such as 5070, so as not to conflict with the SIP port used by RediTALK-Flex. This setting only affects the receive port of the local DRG for DMR-AIS messages. The SIP destination ports can be configured differently for each node (main and redundant nodes) using the DMR-AIS SIP Node 1 10 parameters. DMR-AIS IP Supplement 15

22 DMR-AIS SIP Transport Protocol is the default transport protocol used for DMR-AIS messages. This option is for compatibility with devices and servers that only support one of these transport protocols. Regardless of this setting, the DRG will correctly respond to SIP messages using both UDP and TCP. The URI of the remote device can override this setting. Allowed values: UDP - User Datagram Protocol and TCP - Transmission Control Protocol. Default: UDP - User Datagram Protocol. DMR-AIS ID is the ID used to register with the DMR-AIS system radio controller. Typically this value is a number. DMR-AIS Password is the password used to authenticate the DRG with the DMR-AIS system radio controller. DMR-AIS Server SIP Node 1 10 is the address of the DMR-AIS system controller, and is a SIP URI, such as sip: :5070. The DRG will use the first value as primary controller node. If this server does not respond it will try the next one until it finds an available DMR-AIS server. If no port is specified, port 5060 will be used by default. To configure a port other than 5060, type the node as a SIP URI. For further information about SIP addressing, see SIP URI on page 17. Registration Expiry is how often (seconds) the DRG must re-register with the DMR-AIS system radio controller. Allowed values: 65 to 32,000 seconds. Default value: 900 seconds. Registration Failed Retry Interval is the interval (seconds) that the DRG will wait after SIP registration failed before it attempts to register again. Allowed values: 33 to 32,000 seconds. Default value: 33 seconds. DMR-AIS OPTIONS keep-alive messages option determines whether the DRG sends a SIP OPTIONS message to the DMR-AIS system radio controller. DMR-AIS SIP OPTIONS keep-alive message interval determines how often (seconds) the DRG sends a keep-alive message to the DMR-AIS system radio controller. Default value: 30 seconds. DMR-AIS RTP Receive Port Number is the port number that is used for DMR-AIS RTP packets. The allowed value is an even number from 1024 and Default value is Configuration

23 DMR-AIS RTP Heartbeat Period is the time between RTP heartbeat messages. This heartbeat enables the DRG to detect loss of communications during a radio conversation. The value is in seconds. Default value is 10 seconds. DMR-AIS RTP Transmit Codec selects the codec that is used to encode audio sent to the radio system. Different radio systems from different vendors support different codecs. The possible values are AMBE, G.711 U-Law and G.711 A-Law. The default is AMBE. This setting only affects audio packets sent to the radio system from the DRG device: the DRG device will correctly decode the audio in all three codec types. Note If your radio system supports AMBE, it is recommended that you select AMBE as the codec type. Text Message Format selects the format of the text message sent to the radio system. Different radio vendors support different text message formats and this value should match the recommended value for the particular vendor. This only affects text messages sent to the radio system: the DRG device will correctly decode text messages from the radio system regardless of format. The options are ISO7 (ASCII) Characters, UTF16/Unicode-16 Characters, and UTF16LE/Unicode-16 Little Endian Characters. SIP URI SIP entities are identified using a SIP Uniform Resource Identifier (URI). This is similar to the Uniform Resource Location (URL) used to identify a particular resource on the World Wide Web. The following examples show the general form of a SIP URI and the components that comprise a SIP URI. sip:user:password@host:port;uri-parameters?headers sip:ipr100@ :5070 sip:1009@pbx.company.local sip: @telco.com sip:radio5@police4.gov;priority=urgent DMR-AIS IP Supplement 17

24 Component Example Description scheme sip Identifies the scheme to be SIP. user user The identifier of a particular resource at the host being addressed. Often this is an extension number. password password A password associated with the user. If the SIP server or PBX uses authentication this will be required. host example.com The host providing the SIP resource. This is either a numeric IP address or Full Qualified Domain Name (FQDN). Required. port 5070 The SIP port number where the request is sent. If this field is omitted, the default SIP value of 5060 is used. URI parameters user=phone Parameters affecting a request constructed from the URI. URI parameters are added after the hostport component and are separated by semicolons. headers priority=urgent Additional information added after the parameters. Fleet Numbering The DMR-AIS provides an interface for breaking up portable radio identities into fleets. The DRG supports two such numbering schemes: MPT1327 and MPT1343. These schemes are based on the legacy MPT trunking radio system, and allow radios in the same fleet to be called using a short dialed string or number rather than the full radio number. MPT1327 The radios are identified by prefix and unit identity. MPT1343 The radios are identified by prefix, fleet, and unit identity. 18 Configuration

25 In both cases, a certain range of identities is reserved for group addressing instead of individual radios. In the case of the MPT1343, it is a requirement that the DRG be configured with details of all the fleets in use so that the DMR-AIS unit identifier can be uniquely determined. These configuration details are not actually used on the DRG, but are sent via the CCP link to the dispatch console. The dispatch console then uses this information to transform the numbers entered by the operator into a DMR-AIS radio identity. Also the call and radio identity information sent to the console from the DRG is transformed into a fleet-based number. The DRG works with complete fleet-based identities. Note The Fleet Numbering configuration in the DRG must be the same as the configuration in the node. If the configurations do not match, the fleet numbers will not be translated correctly. Figure 6 shows the settings on the Fleet Numbering page. Currently, fleet numbering is supported by the RediTALK-Flex product only. Figure 6. DMR-AIS interface fleet numbering DMR-AIS IP Supplement 19

26 Enable Fleet Numbering option enables the fleet-numbering feature. Fleet numbering is only required for radio systems that support it particular radio vendors use fleet numbering. If your radio vendor does not use fleet numbering, you should deselect this option to disable the function. If this option is deselected, the DMR- AIS radio number will be used by the console without any modification. Fleet Numbering Scheme selects MPT1327 or MPT1343. Note The MPT1327 scheme requires only the Prefix setting; all the other settings are disabled for this scheme. Prefix selects the prefix associated with this DRG. This value is needed for both MPT1327 and MPT1343. For MPT1327, this is a number in the range For MPT1343, this is a number in the range Fleet Number Unit is the MPT1343 fleet number associated with this DRG. This is a number in the range First Unit is the identity of the first unit in this fleet, which can be 20 or 200. A value of 20 means the fleet is a small fleet with up to 70 radios. A value of 200 means the fleet is a large fleet with up to 700 radios. Fleet Group Number is the fleet group number associated with this fleet. It is a value in the range 5000 to First Group is the first group in this fleet, which can be 90 or 900. As for the first unit, this value determines if the fleet has a small set of groups up to 10, or a large set of groups up to 98. When you select the MPT1343 (prefix + fleet + unit) fleet numbering scheme, an additional table of DMR-AIS address details is displayed. This table provides details of the DMR AIS unit addresses that correspond to the configured MPT1343 fleet address ranges. The first row contains the details for the local fleet configuration. If the configured address ranges are not configured correctly, it is possible that the DMR AIS might be in more than one of the configured fleets. In this case, a warning message will be displayed. 20 Configuration

27 If the local fleet configuration is not configured correctly, it is possible that the DRG DMR-AIS address might not be within the fleet range. In this case, a warning message will be displayed. Figure 7 shows a configuration with all three configuration mistakes. Figure 7. DMR-AIS address details with erroneous configuration Fleet Configurations The DRG can support up to nine fleet configurations: one local fleet that contains the DRG address and eight additional non-local fleet configurations. Figure 8 shows the Fleet Configuration settings. Figure 8. Fleet configuration settings DMR-AIS IP Supplement 21

28 Configuration Example 1 The customer site uses a single prefix (200) and has three fleets as follows: Fleet 1: Units (100 units) Groups (20 groups) Fleet 2: Units ( 100 units ) Groups (20 groups) Fleet 3: Units ( 100 units ) Groups (20 groups) The DRG/Console position is in Fleet 1. So the configuration for that fleet becomes the DRG local fleet. Figure 9 shows the DRG configuration for this example. Figure 9. DRG configuration for example 1 22 Configuration

29 Configuration Example 2 The customer site uses two fleets with different prefixes. In this case, the console is in the Fleet 2, which is the DRG local fleet. Fleet 1: Fleet 2: Units (100 units) Groups (20 groups) Units (100 units) Groups (20 groups) Figure 10 shows the DRG configuration for this example. Figure 10. DRG configuration for example 2 DMR-AIS IP Supplement 23

30 GPS Figure 11 shows the settings for GPS configuration (the settings are the same in both Basic and Advanced modes). Figure 11. Settings for GPS Enable option enables the reporting of GPS information via a proprietary Tait API. This option is for use with Tait Radio Nodes only; however, it will not affect the operation of radios that report GPS information via the DMR-AIS protocol. Port Number is the port number that the GPS server will listen on for incoming connections. The standard HTTPS port 443 is commonly used. Override GPS Host address option allows you to override the address for the host node. Select this option if you have multiple nodes and you want the GPS data from one node only. If selected, the host address specified in the Host Address property below will be used; otherwise the same IP node addresses that are normally used for DMR-AIS communications will be used. Host Address specifies the IP address of the host node from which you want to receive the GPS data. Only available when the Override GPS Host address option above is selected. Username specifies the user name to log into the GPS server. This is required a when the DRG connects with the GPS server. Password specifies the password to log into the GPS server. This is required when the DRG connects with the GPS server. 24 Configuration

31 Poll Interval is the time between each request for GPS location data from the DMR node. Valid interval is from 1 to 900 seconds. The DRG polls the unit data in blocks of 50 units at a time. If you have a large number of radios (1000 or more), you should probably set the Poll Interval to no more than 10 seconds. This will give an update time of about 200 seconds (10 * 1000/50) without too much CPU loading on the DRG. Report GPS for units without valid fleet option reports GPS location data even when no valid fleet information is available. If this option is not selected (the default) and MPT1343 fleet numbering is in use (enabled on Fleet Numbering page), the DRG will only report GPS coordinates for those radios with a valid Fleet ID. This allows the DRG to filter GPS values on sites where there are multiple fleets in use at the same time. Report GPS for units without valid fix option reports GPS location data even when the radio unit does not have a valid GPS fix. If selected, this allows reporting of stale GPS data, which might be stored on the node/controller. If not selected, only radio units with a valid GPS fix will be obtained from the node/controller. Request GPS Mode selects the mode to use for requesting GPS data and can be set to Request All (MAX 200) or Request Blocks. Note The Tait GPS interface has a limitation that prevents the GPS data requests from working when the number of radios reporting GPS is more than 200. If your radio system has more than 200 radio terminals, you will need to configure the GPS interface to request the information in blocks: select Request Blocks for the Request GPS Mode setting. In this mode, it is also necessary to configure the minimum and maximum radio identities that the GPS will request. You should set these to the range of radios actually in use at the site. The DRG will request radios in blocks of 50, so if you have a large range of radio identities, it may take several minutes to update all the GPS locations. Minimum GPS Unit ID specifies the first GPS unit ID to poll. Maximum GPS Unit ID specifies the last GPS unit ID to poll. DMR-AIS IP Supplement 25

33 Diagnostics and Statistics This section discusses the diagnostic features of the DRG and how to use these features for testing DMR-AIS IP, and includes the following topics: Digital Radio Diagnostics Statistics on page 33 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 Diagnostics to view the Digital Radio Diagnostics page, as shown in Figure 12. Some of the diagnostic sections may not be visible depending on whether the corresponding capability is enabled on the Digital Radio configuration page (see Digital Radio Settings on page 9). For instance, if you select the Disable Text Messaging option to disable the textmessaging capability, the Send Text Message section will not be shown. DMR-AIS IP Supplement 27

34 Figure 12. Digital-radio diagnostics page for DMR-AIS Digital Radio Call The Digital Radio Call section allows you to perform several diagnostic tests associated with Call Setup and Group Registration, as discussed below. Call Setup Use this section to set up and test a particular call type. Call Type selects the type of digital-radio call to make. Some of the call types may not be available depending on whether the corresponding call-type capability is disabled on the Digital Radio page (see Digital Radio Settings on page 9), and how the radio is configured, but may include the following: 28 Diagnostics and Statistics

35 Default Call Type Individual Call Group Call All Call Next radio call will be the default for this radio A call to a single radio A call to all radios in a particular group Calls all radios on the network Destination: Radio ID or Group ID specifies the unique identity of the radio, or the group of radios, that 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 of the radio, or group of radios, 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 Pushto-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 32). Group Registration Group Register and Group Unregister allow you to register and unregister a particular group of radio repeaters: registering allows you to test for the existence of a particular group of radio repeaters. Group Register ID is the unique group identity of the radio network to be associated with this DRG once registered. To associate this DRG with a particular group of radio repeaters/base stations, type the identity of the group into the Group Register ID text box, and then click Group Register. Once this DRG is registered, you should see the identity of the group appear next to Group ID status under the Radio Status section. To remove the association of this DRG with a particular group, type the identity of the group into the Group Register ID text box, and then click Group Unregister. Once this DRG is unregistered, a group identity of 0 will appear next to Group ID status under the Radio Status section. This indicates that this DRG is no longer associated with a group. DMR-AIS IP Supplement 29

36 Send Text Message The Send Text Message section allows you to send a text message to the specified radio or group. Message Type allows you to select the type of message to send and can be one of the following: Individual or Group. Destination Radio ID or Group ID is the identity of the radio or group of radios to which you want to send the message. To send a text message, select the type of message from the Message Type dropdown list, type the destination of the radio, or group of radios, into the Destination: Radio ID or Group ID text box, and then click Send Text. Radio Status Message The Radio Status Message section allows you to send a status message to the specified radio or group of radios. Message Type allows you to select the type of status message to send and can be one of the following: Individual or Group. Destination: Radio ID or Group ID is the identity of the radio, or group of radios, to which you want to send the message. Status Message Number is the number of the status message to send. To send a status message, select the type of message from the Message Type dropdown list, type the destination of the radio, or group of radios, into the Destination: Radio ID or Group ID text box, type status message number into the Status Message Number text box, and then click Send Status to send the status message. 30 Diagnostics and Statistics

37 Remote Radio Commands Use the Remote Radio Commands section to send commands to a particular remote radio. Note Some of these commands may not be available depending on whether the corresponding capability is disabled on the Digital Radio page (see Remote Radio Commands on page 12), or the console may not support a particular command. Command is the command you want to send to the radio. The commands available will depend on the capabilities and configuration of the radio, but may include the following options: Radio Check Stun Radio Revive Radio Monitor Radio Sends a Radio Check command to a particular radio ID to determine whether the radio is powered on and receiving. Sends a Stun Radio command to a particular radio ID to temporarily disable (stun) the digital radio (it can be re-enabled with the Revive Radio command). Sends a Revive Radio command to a particular radio ID to re-enable (revive) the digital radio that was previously stunned. Sends a message to radio terminal and places the radio into monitor mode. Destination Radio ID is the identity of the radio to which you want to send the command. To send a command to the radio, 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. DMR-AIS IP Supplement 31

38 DMR AIS Specific Functions The DMR-AIS Specific Functions section provides functions that are specific to the DMR AIS interface and include the following: DMR AIS Function is the type of function to perform and includes the following: Force Re-register (simulate server change) Set/Clear Emergency The causes the DRG to re-register with the DMR AIS server. This is the same behaviour as if the DMR AIS server has indicated that the server status has changed. Sets/clears sending all DMR AIS SIP messages with the priority set to emergency. Value toggles to clear emergency after the set emergency function has been invoked Important The Set/Clear Emergency function is intended for testing only and should not be used with a live radio system. Radio Status The Radio Status section displays the status of the digital radio connected to the DRG. The contents depend on the functionality of the radio 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. 32 Diagnostics and Statistics

39 Group ID indicates the active group (transmitting or receiving). Last Text Message Received shows the last text message received from a radio. Last Text Message Sent shows the last text message sent. Registered Group shows the currently registered group. Statistics Select Statistics under the Diagnostics menu to display the Statistics page similar to the one shown in Figure 13. This page is the same in Basic and Advanced modes, and provides comprehensive statistics about the DRG operation. Figure 13. Statistics page for DMR AIS DMR-AIS IP Supplement 33

40 DMR-AIS RTP Statistics This section is applicable only to DMR-AIS and shows the statistics for the VoIP packets that flow between the DRG and the DMR-AIS base station. The meaning of each of the entries is the same as described in the section Omnitronics RTP Statistics below. 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. 34 Diagnostics and Statistics

41 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 0 is the total number of RTP packets with a payload number of 0. RTP Payload 8 is the total number of RTP packets with a payload number of 8. 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 valid bytes is the total number of bytes received via RTCP. Time since valid RTCP packet is the time in milliseconds since the last RTCP packet was received. Source Name is the name (address) of other IPR/VoIP devices communicating with this DRG, such as: IPR110Plus:Group1@ Location is the location or name configured in the remote DRG device, such as DxAltus Radio Channel 1. Firmware Information identifies the firmware, and the version of the firmware, that this IPR device is running. Source IP Address is the source IP address for this audio source, such as Source UDP Port is the UDP Port for this audio source, such as 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). DMR-AIS IP Supplement 35

42 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 how much audio (in milliseconds) the DRG device is currently holding 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 remote audio source requested for the local DRG PTT output. This will appear if the remote site currently has an active busy signal from a connected radio. 36 Diagnostics and Statistics
