Descriptions
URR-5P is designed for organizing a radio cable channel in the Stream-2 equipment using digital protocol DMR. URR-5P is enclosed in a separate anti-vandal metal case and can be connected to both the station set (as a radio base station) and to the regenerator module in the path. The repeater radio station has a radio station, a repeater, a duplexer and a power supply unit.
Scopes
- Computerized dispatcher’s workstation.
- Full control and GPS positioning of radio network subscribers.
- Basic equipment monitoring.
- Switching and routing of calls.
- Record all events and radio network negotiations.
- Output to the telephone exchange.
