16.12 17.2

Description (partial)

Symptom:
In scaled setup if few T1s or lower order circuits are down with alarm, post redundancy switchover, the T1s would appear as up without alarm, but actually they are down with alarms.

Conditions:
Redundancy switchover is causing some of the alarms at T1 or lower order level to not report to router.
This might give wrong impression of alarm clear  to NMS, since the alarm is not cleared yet
