DIPRA DispatcherThe DIPRA® Dispatcher Location serves as a means to manage a fleet of mobile users via a DIPRA® DMR Tier III Radio Network. It is connected to the DIPRA® Switch exploiting an IP interface and facilitates a simple and intuitive call set-up by means of a Graphical User Interface (GUI).

The following functions are part of the basic version of the DIPRA® Dispatcher Location utilizing a single screen:

  • Set-up of individual calls, group calls and conference calls, acceptance of individual calls.
  • Alternatively, calls may be sent to individuals or to mobile radios. As a prerequisite, users have to register with their user-ID.
  • Calls may be put on hold, toggled between them, connected and monitored.
  • Set-up and acceptance of emergency calls with optical and audio alerting. If necessary, existing calls are cleared down in favor of the emergency call.
  • Identification of calling or called users, displayed by their calling numbers or by their names.
  • Recording and playback of calls at the DIPRA® Dispatcher Location.
  • Authentification of the dispatcher with name and password.
  • Usage of multi-level user profiles with different access rights.
  • Simple customization in terms of GUI, audio signals and audio level, etc.
  • Multi-lingual support of the user interface.
  • Encryption of digital signals between DIPRA® Dispatcher Location and DIPRA® Switch.

A variety of additional functions allow the precise adaptation of the DIPRA® Dispatcher Location to the requirements of a customer project:

  • Pre-defined or free text messages may be submitted to individual users or groups.
  • Text messages may be received, modified and redirected to others.
  • Display of registered mobile terminals by automatic periodical test on their reachability.
  • Graphical support for the set-up of dynamic group calls.
  • Display of mobile user positions and routes on maps.
  • A second screen may be installed to improve the overall view for the dispatcher.
  • Automatic centering of the position of the mobile user on a map displayed on the screen in case of an emergency call .
  • Multi-client capability for using the DIPRA® DMR Tier III Radio Network by several fleets.
  • Support of security functions of mobile terminals, e.g. a man down feature.
  • Locking and unlocking of a mobile terminal (e.g. after a terminal is lost).

Hardware Components

The DIPRA® Dispatcher Location consists of a modular system of components, thoroughly geared to each other, in order to facilitate an ergonomic and a fatigue-proof usage even over a longer period of time:

  • 17“-touch screen with integrated industry PC.
  • Integrated loudspeaker and interface for an external loudspeaker.
  • Handset with tray.
  • Goose-neck microphone with Push-to-Talk function (PTT). [Option]
  • Headset, wireless [Option].

 The European Telecommunications Standards Institute (ETSI) has set the basis for a world-wide accepted Professional Mobile Radio (PMR) technology with its DMR specifications TS 102 361 part 1 to part 4.

The specifications offer two levels of complexity - Tier II and Tier III - for operating mobile terminals with repeaters and for radio networks with a switchboard, respectively. Both tiers are exploiting licensed spectrum.

RADIODATA develops, manufactures and sells DMR Tier III Radio Networks under the brand name DIPRA®, comprising switches, basestations in standard or simulcast technology, mobile terminals, mobile data modems, dispatcher locations and custom-tailored applications. DIPRA® DMR Tier III Radio Systems allow to set up scalable and exclusively usable voice and data communication networks.

DIPRA® Radio Networks support the versatile facilities of data communication as laid down in the DMR specification.
