Repeater Hytera RG625 VHF DMR Official 25W including power supply
The RD625 is a digital repeater designed specifically to provide reliable radio coverage in buildings and tunnels. The RD625 has been developed in accordance with the Digital Mobile Radio (DMR) open ETSI standard and can be operated with either digital or analog signals. 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. The RD625 repeater provides a connection to existing VoIP telephone systems on the DMR radio network as SIP subscriber. 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. The RD625 repeater provides a connection to existing VoIP telephone systems on the DMR radio network as SIP subscriber. 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. The integrated power supply of the RD625 automatically chooses between alternating current and direct current. This makes it possible to provide a fail-safe 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. With air interface encryption signaling and communications data between radios and repeaters are transmitted with reliable protection. The RD625's well-engineered design makes wall mounting easy using the optionally available wall bracket. This makes it possible to install the repeater flexibly and conveniently in buildings.

The RD625 combines transmitter and receiver components, the power supply and the duplexer (optional) in its compact chassis. The RD625 can be monitored, checked and controlled using a PC-based application. The software supports network access from multiple points and allows administrators to monitor the DMR radio network. To ensure a high level of security, the RD625 features a repeater access monitor that protect the radio network from unauthorized access attempts.
