Abstract
A method and system for providing an alternate common channel signaling system path. The alternative signaling path that does not rely on the same hardware or software that is used for a primary signaling path. The alternative signal path allows network devices on a local area network to be signaled when a primary signaling path to the local area network has failed. The alternative signaling paths may provide better fault tolerance for connecting local area networks to other external networks.
