Abstract
In an optical communications network, the supervisory control signal is duplicating at the OSI layer 2 or layer 3 level to generate a primary supervisory control signal and a secondary supervisory control signal. Access to the primary supervisory control signal is enabled at a network interface of a network device. In response to detecting a failure of the optical communications network or the device, access to the primary supervisory control signal is disabled and access to the secondary supervisory control signal is enabled.
