Enhanced RCA Cases for Signal Degrade and Transmit Ports

This section provide information on enhanced RCA cases for Signal Degrade and Transmit Ports.

Correlating aggregate SD (IsSignalDegrade detected) with downstream LOS, LOF, SD on non-aggregate (Transponder) ports.

SignalDegrade on network path will lead to SD, LOS or LOF on downstream Transponders, depending on severity of bend. Upstream/downstream model is extended to support SD correlated with downstream LOS, LoF or SD.

Transmission port (Output port) level failures in RCA correlation with respect to UpStream/DownStream failures.

OTM can now correlate aggregate TX port alarm (root cause) to downstream aggregate LOS (impacts).
