Abstract: A method for a system including a plurality of encoders each for receiving a first signal and encoding to generate a respective second signal for sending to a respective subscriber, comprising receiving, in each encoder, the first signal from a first source, while testing a signal path between a second source and the encoders, the first source on a first assembly, the second source on a second assembly, and each encoder on a respective third assembly, while each encoder is receiving the first signal from the first source, receiving, in each encoder, a third signal from the second source, generating, from each encoder, a fourth signal based on the third signal, the fourth signal being a redundancy signal and receiving and examining the fourth signal at the second source and subsequently receiving the first signal from the second source.

Abstract: A system and method for enhancing reliability in a communication system. In the system and method, redundant signal paths are continuously tested to determine if any faults are present while the operating signal paths are in use. If any faults are present in the redundant signal paths, they can be addressed while the operating circuits are still in use. This minimizes the chance that a switch from an operating signal path to a redundant signal path because of a fault in the operating circuit will result in downtime.
