Hytera DWS - dispatcher system

Efficient and professional dispatching for TETRA and DMR trunking.

    Product description

    The application Dispatch WorkStation (DWS) from Hytera is an application for efficient subscriber handling in the radio system. Dispatchers can be used as logistics and control centers to manage and control the radio subscribers or they serve as a control unit for monitoring alarm functions. The dispatcher administrates all the data in respect of the assignment of fleets, groups and radio subscribers in the radio system and simplifies the management of the subscriber communication.

    Versatile functions

    The DWS not only offers conventional features such as group calls, individual calls or emergency calls. Enhancements such as dynamic group number assignment (DGNA), include calls (group patching) or discreet listening (monitoring) are also available. In addition to voice functions the DWS also supports sending and receiving short messages and status messages.

    Positioning of radio subscribers

    For positioning radios via their GPS position data, DWS offers a map service for the display of the geographic location of subscribers. The mapping data is stored locally at the workstation, which makes an Internet connection unnecessary. Advanced functions such as geofencing or task allocation to radios supplement the subscriber handling.

    Reliability through redundancy

    To secure dispatcher functionality, the system can be equipped with redundant server and connection. So if a server should fail, subscriber control can continue. The DWS supports a wide variety of security aspects such as password protected access and assignment of function rights for different DWS user groups.

    Various external devices

    Besides the standard mouse and keyboard, the system supports other external tools such as several multi-touch screens, desk microphones with integral PTT buttons, and foot switch with PTT.


    • All the functions are on one user interface
    • Permanent disabling (killing) of radios.
    • Support for various methods of searching contacts, for example by category, by marking color and by user-defined search (by entering SSI or name).
    • "Group patch" and DGNA groups
    • Monitor management – In this way you can be sure that you are always connected to relevant group calls or individual calls.
    • Uses various map systems to display subscribers.
    • Select the radio directly from the map to start a call or message directly.
    • Offline maps for AVL in an independent secure system.
    • Configure "Geofences" - areas with configurable access rules for particular radios.
    • Create DGNA groups directly on the card.
    • Route tracking: View the movement progression of individual radios.
    • Send tasks to radios. A radio response list indicates the confirmation or rejection of the task (task management)
    • The DWS can be adapted in detail to suit individual customers and to fit the requirements of any radio system.
    • Each work-station can be equipped with individual functions.
    • Dispatchers can assign radios, groups and dynamic group number assignment (DGNA) according to the administration rights they hold on their own DWS work-station.
    • Each DWS work-station can connect to two servers with server redundancy. If "server 1" fails, "server 2" takes over operation. DWS users can continue to work undisturbed.
    • Group configuration and function allocation for each work-station is stored on the server. So dispatchers can carry out their task from any computer work-station without having to re-configure.
    • The server and work-station can connect via two separate ACCESSNET®-T IP Gateways.
    • Temporary locking and unlocking of radios (Enable/Disable)
    • Monitoring of the current status of radios, including the registration status on the radio system as well as at the current base station, GPS position data and speed of movement
    • The interface can be adapted to specific customer requirements
    • The software is scalable to suit anything from small radio systems to major radio networks covering entire regions
    • Fast operation with touch optimization and the latest WPF framework
    • Redundancy of servers, databases, and system connection creates high level of system stability
    • IP structure ensures flexibility when preparing
    • Multiplex support for voice calls, including semi?duplex, full duplex and group calls, emergency calls, broadcast calls, mass calls, as well as PSTN and PABX calls.
    • Divert and hold calls.
    • Add more subscribers to group calls, or force an end to group calls.
    • A call list with detailed information on all calls, as well as start time, duration, and subscribers’ voice activity.
    • Different sound and visual options to signal calls, enabling fast reaction times, particularly in emergency situations.
    • Ambience Listening
    • Callback request to the dispatcher.
    • OOCI integration permits convenient object-orientated calls.
    • The participation of radios in group calls can be acknowledged using the "Ping Response" function.
    • Support by text messages, standard messages and status messages.
    • Messages can be sent quickly to several subscribers at once, by selecting from a list.
    • "Flash messages" are immediately displayed on selected radios. So users cannot miss them.
    • The server is able to back up its database to external data carriers at configurable intervals and restore it if necessary.
