Abstract
Redundancy ring communication apparatus having a plurality of communication channels, that comprises normally used and redundant amplifier channels that are interconnected using selectively controllable switches. Pairs of amplifier channels may be selectively coupled together using controllable switches and hybrid couplers. A controller is coupled to each of the switches that selectively sets the switches to (1) route selected signals through independent communication channels, (2) route a selected signal through the pair of amplifier channels to provide a high power output for the selected communication channel, (3) route a selected signal through a redundant communication channel in the event of failure of another communication channel, and (4) route the signal of the normally unused communication channel that is normally amplified by the second amplifier of the paired amplifier channels operating in high power mode through an unused amplifier channel to provide a communication channel for the signal of the normally unused communication channel.
