What is zhoneOnuStatusAlarmLOS?
This read-only TruthValue reports whether the ONU has a Loss of Signal alarm active, meaning no valid optical signal is being received — the MIB notes this can also be derived from the combined OAML, FRML, and LCD conditions all being true. This is usually the first alarm to check when an ONU appears completely offline, since it points to a fundamental downstream signal problem.
