Abstract

A method and system for providing tandem protection in a communication system. Path, protection is provided using at least two redundant communication paths (42,44) and selecting the communication path having a higher signal quality. Interface protection is provided through a protection transceiver (24). The interface protection may be delayed while the path protection attempts to restore communication.
