Abstract
A network element configured to operate in an Optical Transport Network (OTN) network includes one or more modules including a first regenerator port and a second regenerator port, wherein the one or more modules are configured to provide a Low Order (LO) regenerator function; and circuitry configured to detect the one or more modules are part of the LO regenerator function, and, responsive to detection of a fault on the first regenerator port, cause forward traffic conditioning at a High Order (HO) path to the second regenerator port. The forward traffic conditioning can include an Alarm Indication Signal (AIS) on the HO path.
