Abstract
Communicating a signal includes receiving the signal at a primary device of a switching system, where the primary device is associated with a primary path along which the signal is propagating. A primary overmodulation signal associated with the primary path is generated. The absence of the primary overmodulation signal is detected, and an operating signal is sent from the primary device to a secondary device of the switching system, where the secondary device is associated with a secondary path. The operating signal operates to initiate propagation of the signal along the secondary path.
