What is e3LineStatus?
This OID is a bitmap integer (1–1023) that combines multiple line condition flags: NoAlarm, Remote Alarm Indication (RAI), AIS (All Ones), Loss of Frame (LOF), Loss of Signal (LOS), and loopback state. Network engineers monitor this continuously to detect transmission failures and alarms that require investigation or repair. For example, a value combining 2 (RAI received) and 64 (LOS) means the E3 link has lost synchronization and the remote end is sending a yellow alarm, indicating serious line trouble.
