What is oc3LineStatus?

This read-only OID reports the OC3 line's health as a bitmask integer (1-8191) where each bit represents a specific alarm: loss of signal, loss of frame, AIS (Alarm Indication Signal), or remote alarm indication. Operations teams continuously monitor this to instantly detect line failures and trigger automatic failover mechanisms or alert engineers to circuit issues. A value of 64 indicates 'LOS' (Loss of Signal), meaning no valid signal is being received and the line is completely down.

Examples
