The instance of the alarm for this NE. This variable is used to identify a unique row for each alarm. In the nmsNEAlarmTable a sequence of alarms will look like: TID alarmIndex Other Alarm Data ======================================================== TID1 1 1-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 TID1 2 2-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 TID1 3 3-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 TID2 1 1-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 TID2 2 1-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 TID3 1 2-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 TID3 2 3-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 TID3 3 4-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 TID3 4 5-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 TID3 5 6-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 TID4 1 1-1 oc3 CR LOS SA RCV Loss Of Signal neTimeStamp1 nmsTimeStamp2 i.e. For each TID alarmIndex starts with 1 and is incremented by 1. This is to help retrieve alarms on an NE basis.
