The DIPRA^® dispatcher location serves as a means to manage a fleet of mobile users via a DIPRA^® DMR Tier III radio retwork. 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:

• Touchscreen
• 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.
