Abstract
A network element includes a client port configured to receive a signal for transmission; a line port configured to transmit the signal to a far end via Optical Transport Network (OTN); circuitry configured to communicate one or more of a fault and a status associated with the signal to the far end via OTN overhead. The circuitry configured to communicate can be for the fault and utilizes one or more Tandem Connection Monitoring (TCM) layers in the OTN overhead. The circuitry configured to communicate can be for the status and utilizes one or more of Optical Data Unit (ODU) Performance Monitoring (PM) and one or more Tandem Connection Monitoring (TCM) layers.
