Abstract
A redundant communication system contains a principal transceiver and a back-up transceiver to be controllably substituted for the principal transceiver. A monitor protection switch, which controls swapping the two transceivers, has an RF loopback test circuit that is switchably coupled to whichever transceiver is the back-up. The RF loopback test circuit monitors the operational capability of the back-up transceiver, and provides an indication of its functionality. If the back-up transceiver is defective, corrective action can be taken in advance of a potential operational failure of the principal transceiver. As long as the RF loopback test circuit indicates proper operational capability of the back-up transceiver, the redundant transceiver can be immediately switched in place of the principal transceiver.
