  • In locations where normal TMO network coverage is unavailable or unreliable, users can switch their radios to Direct mode to maintain communication.

    To increase the distance between two Direct mode users, place a Sepura radio operating as a DMO-Repeater in between. Calls made from one DMO radio via the DMO-Repeater will be rebroadcast to other DMO users.

    Key Features

    • Voice calls (Encrypted and Clear)
    • Status and SDS message
    • Emergency calls
    • Call Participation and Call Monitoring

    Type

    • Type-1A-DMO-Repeater for efficient spectrum use

    A DMO-Gateway creates a communication link between TMO network users and DMO users. The DMO-Gateway re-transmits data received between the two types of users.

    DMO-Gateway can be used by users who cannot connect to the TMO network, perhaps because they are in a network blind spot such as a tunnel, or within a building. A DMO-Gateway placed within the TMO coverage enables the extension of network coverage in such blind spots, connecting the DMO users to the network.

    Key Features

    • Voice and Data
    • Intelligent call conversion
    • Safer operations

    A fixed level audio output is provided in the SRG3900 mobile radio. This is available on Interface 2 and is independent of the output audio level on Interface 1 and the loudspeaker connected to the mobile transceiver.

    Mobile radios can support audio input on one or both of the console interface connectors without a physical Console or Audio Interface Unit (AIU) being present. This allows installation of 3rd party control heads operating the radio with control of audio accessories bringing saving in investment and maintenance.

    A Short Data Application (SDA) enables a Sepura terminal user to send and receive information in a user friendly form based environment. This makes sending and receipt of SDS message an effortless task by presenting the user with information in a form that is simple and easy to read. Typically, an SDA will help the end user with an existing work flow process by improving user experience and making efficient use of time.

    Features in this pack follow on from the SDS Templates functionality released in V5.0, enhancing it by providing the ability for end users to define their own templates, supporting user defined protocols and applications.

    Radios are normally configured to route messages and voice to pre-configured destinations. With this feature, radios can be further configured to route status messages, position reports and emergency voice to a destination other than the pre-configured defaults. The alternative destinations are determined at run time based upon the Selected talkgroup. Change of Selected talkgroup automatically changes the destination address for the following functions;

    • Quick Status Destinations triggered via softkeys
    • Default Status Destination triggered via menu and/or the Mode Key
    • Primary Position Destination

    Radios support a number of features that can be configured to suit a user’s operational requirement. Some radio settings e.g. backlight resolution, alert level, active speaker etc. can be further adjusted during run time. This feature resets the radio back to the default configuration eliminating personal preferences.

    An option to preserve Phonebook, talkgroup and message boxes is available. If enabled, the reset option retains these data.

    Reset option can be activated from from the menu syetem, softkey, over the air and when integrated into an SDA.

    Radios can be configured with a list of up to 150 Location Areas (LA). The radio prefers these LAs when acquiring a cell at switch on or during re-selection. However, if the coverage gets weaker or non-existent the radio will register on an LA outside this list. Registering a similar group of users on the same LA ensures efficient use of TETRA resource.

    Additionally, the radio can be forced to only use cells from the the configured LA list. Even if the coverage on these LAs drops, the radio will not acquire an LA outside of the LA list.

    The top level screen of the radio enables a dynamic display.

    The display includes:

    • Radio Status Area
    • Information Area consisting of 4 or 6 lines
    • Shortcut and Notification Bar

    The radio status area comprises elements of variable radio status icons, permanent status icons, and radio status text, depending on the radio.

    The screen can be configured to include an Information Area. Using the Radio Manager, users can add or remove an information line and define how it is displayed. The information line includes display of talkgroup and folder, time, date and PTT mode. These can be formatted with a choice of colour and style for greater visual impact.

    The Shortcut Bar provides means to configure and access commonly used radio features (Shortcuts). It also provides visual status of the radio features (Notifications) on the top level screen. Selecting an icon triggers a radio action relevant to the icon e.g. opens an unread message or alerts the user when the radio is placed in Transmit Inhibit state.

    The transmit power of a radio operating in DMO, DMO-Repeater & DMO-Gateway mode can be set from the MMI. Users are offered an onscreen choice, dependent on the radio's hardware capability, allowing it to be set to the user's choice.

    On selection, an icon indicates whether the chosen power is higher or lower than the default setting. The radios revert to default power setting on a restart. The display text can be configured from the Radio Manager to user’s choice e.g. High Power and Low Power.

    AIM is the TETRA air interface mechanism by which a radio obtains service on a network (visited) other than its own Home Network, i.e. a network with a Mobile Network Identity (MNI) different from that of its Home Network. The use case is the TETRA radio users who may roam into another network, normally another country, for operational use e.g. a fire crew attending an emergency on the other side of the border due to its quicker accessibility.

    E2EE offers an additional and independent level of security to AIE. Encrypted data can only be decrypted by the correct combination of the algorithm and traffic key used by the transmitting party to encrypt the data. This avoids a man-in-the-middle attack as the crypto material is only available with the transmitting and receiving parties.

    The following options for E2EE are available

    • Embedded E2EE (without tamper protection)
    • ESM Protected E2EE (with tamper protection)
      • In-Country (Private, Local) E2EE algorithm
      • Multiple E2EE algorithms
    • Smart Card E2EE

    Please contact your account manager to discuss your requirements.

    The feature enables the radio to operate with AIE Security Class 3G (SC3G), i.e. use of GCK on a Security Class 3 (SC3) network that supports SC3G.

    Out of Coverage Position Report Buffer

    Sepura radios equipped with GNSS receivers determine the user’s position and then automatically inform the command centre of the radio’s position. Knowing the user’s position ensures whereabouts are known at all times and officer’s safety is ensured. Position reports also monitor a user’s movements ensuring time and resource is efficiently managed.

    The out of coverage reports can be used to analyse network black spots and piece together the user’s activity.

    Fake Switch Off

    The feature allows discreet tracking of switched off radios. With the feature enabled, the radio does not power off completely when the switch off button is pressed. The radio enters a fake switch off state where TETRA services are denied to the user and all display and alerts are disabled. To the user the radio appears to be switched off. However, the radio continues to send position reports allowing the radio to be tracked by authorised personnel.
