Herning D.H.R.

Telephone interface telephone gateway, phone patch

Datahertz have developed a set of affordable applications for all radio users to extend their Mototrbo use.


As an automated management of the radio network, Herning D.H.R. Telephone Interface provides a gateway between the telephone network through analogue private and public land lines, GSM modem or Inmarsat satellite systems and a two way radio analogue or digital network, computer systems via port RS 232 (for computer, printer and modem) and external audio equipment via a microphone input and speaker output (for intercom, desktop and speech synthesis).

The installation of the Herning D.H.R. Telephone Interface is easy, and full support is provided by a hotline service.

A typical application for the Herning D.H.R. Telephone Interface is security. With the DHR Telephone Interface, a security guard can at the same time manage incoming phone calls, technical alarms and control access. The interface functionalities then integrate to give a safe radio link test, alarm management (up to 42 alarms), lone worker safety and guard tour features.
