Hot Standby Half Duplex Radio - QP450
Typical Radio Setup
Operational Description
The QP hot standby half duplex radio, is a 1RU rack mounted module which operates with two internal highly reliable half
duplex radios, which can be switched between to provide redundancy.
The two half duplex radios (Radio A & Radio B) operate simultaneously and depending on the QP antenna option, there are
differnet antenna arrangements available:
- Option B: Duplicate Ports - This option provide a separate antenna port for each of the internal radios.
- Option E: Common Port - This option will connect the internal radio’s antenna ports through an RF relay, providing
a single antenna port on the QP.
Only data received by the “online” radio is directed to the user equipment. The online radio is also the only unit transmitting
at any time. The QP can perform the following functions:
• Monitor the alarm output from both radio A and radio B and change over the online radio if required.
• Switch all user data through to the online radio.
• Switch the antenna via internal coaxial relay to the online radio transmitter (Requires QP Kit Option E).
Digital switching in the QP directs user data to and from the user ports on the front panel directly to the user ports of the online radio.
