A method and apparatus of managing remote third party OTN & WDM transceiver equipment using the same fibers used for end user data exchange is described. A network device collects management instructions for the OTN & WDM transceiver equipment, assembles this management information into the overhead of a data frame and transmits on an optical link directly coupled to the network device. The WDM transceiver function converts the optical signal to an electrical one and the OTN function extracts the management instructions from the OTN overhead. A processor associated with the OTN framer function acts on that information. The management instructions includes the instruction to periodically and continuously, load certain performance, alarm or informational data into its OTN overhead and transmit that to a similar transceiver at the remote end of the communications link. Network-based monitoring equipment can optically tap off a portion of the signal and extract this information, allowing the network-based device to gain knowledge of conditions at the end points.
