RADIO / IP NETWORK INTERFACES
Voice over IP for analogue radio systems IPR 100 and IPR 400
Control and monitor repeater sites
The IPR 400 is ideally suited to repeater sites that feature
shared equipment or multiple tranceivers. Through its site monitoring facilities,
the device can provide status and alarm reporting to the communications center.
Consider the following example of a repeater site with two UHF and two VHF transceivers,
belonging to two different agencies. The IPR 400 acts as the IP gateway for
the analogue radios. Any audio that is received from any one among the four
radios will be multicast to the WAN. Dispatch systems such as the DX-64 will
receive and process the audio. This means that dispatch operators at the different
agencies can monitor all communications through that repeater site. It would
also be possible for the different operators to broadcast on any of the remote
transceivers, if desired.
