Flexible IP networking

Hytera's DMR repeater can be connected to an IP-based communication network with multiple sites. The roaming function is used to provide radios in this radio network with voice and data services across cells.

Connecting VoIP private automatic branch exchanges

The RD625 repeater makes it possible to connect existing VoIP telephone systems to the DMR radio network. This allows DMR radio subscribers to hold half-duplex conversations with participants from the telephone network. Telephone subscribers have the option of making either individual or group calls in the radio network.

Analogue and digital operation with the ability to switch automatically

The RD625 repeater can be operated both in analogue and in digital mode and is completely compatible with analogue systems currently in use. The device automatically changes between digital and analogue mode depending on the type of receiver signal, saving both time and money by eliminating the need to congure frequencies and channels manually.

Automatic AC/DC switchover

The integrated power supply of the RD625 automatically chooses between alternating current and direct current. This makes it possible to provide a failsafe radio signal by connecting the repeater to an independent source of direct current (UPS) in addition to the normal supply of power. If the AC supply fails, the RD625 switches to the second power supply automatically.
