ABSTRACT:
A method and apparatus for restoring communications in a network. The network includes a plurality of nodes, with each pair of nodes connected by a link, and with each link having information channels and restoration channels. An idle signal is sent on each restoration channel for each link. The failure of a link is detected, with the failed link connecting an originating node with a terminating node. In addition, the failed link includes at least one information channel carrying information signals. An alternate path through the network is determined for the information signals using restoration and idle signals sent over the restoration channels. The information signals are then routed from the originating node to the terminating node in accordance with the alternate path.
