Abstract
A communications network includes a transmit node and a receive node. A first transmission line extends between the transmit and receive nodes and includes a primary embedded channel for carrying channel traffic between the nodes and normal operation. A second transmission line extends between the transmit and receive nodes and includes a secondary embedded channel for carrying the channel traffic between the nodes in the event of a fault condition on the primary embedded channel. The transmit node is operable to automatically switch transmission of the channel traffic from the primary embedded channel to the secondary embedded channel in response to a fault condition being detected in the primary embedded channel at the transmit node. The receive node is operable to automatically switch reception of the channel traffic from the primary embedded channel to the secondary embedded channel in response to detection of the same fault in the primary embedded channel by the receive node.
