After starting the extended SSM protocol, in addition to judging the clock quality level and priority, it also judges the clock ID. After the network element receives the clock signal with ID, if it is judged that the clock signal is sent by the local station, the source is considered unavailable. In this way, even after passing through multiple sites, the network element can still recognize the clock signal sent by itself, preventing the formation of a timing loop.

For the relay OTU, all SM segment alarms are terminated at the local station and no longer sent downstream (except for OTUkLOF to insert ODUk_PI_AIS downstream). Other alarms continue to be transmitted to the downstream station and reported on the WDM side of the OTU (except for R_LOS to insert ODUK_PM_AIS to the downstream station)
