Two Common Alarms

Two Common Alarms

This section describes two common alarms: alarm indication signal (AIS) and remote defect indication (RDI).

Alarm Description
AIS

When an AIS alarm is reported, the system inserts all 1s into the lower-level circuits to indicate that the signal is unavailable. The MS_AIS, AU_AIS, TU_AIS, E1_AIS, and T1_AIS alarms are common AIS alarms.

RDI When detecting the loss of signal (LOS), AIS, or trace identifier mismatch (TIM) alarm, the opposite NE sends the RDI alarm to the local NE.

The MS_RDI, HP_RDI, and LP_RDI alarms are common RDI alarms.

NOTE:

The generation of an alarm on an NE does not necessarily indicate that the NE is faulty. The alarm may be generated due to a fault on the opposite NE or due to other causes.

For example, the R_LOS alarm is generated due to a fiber cut, or the HP_LOM alarm is generated on the local NE due to the failure in the cross-connect unit on the opposite NE.
