Restrictions for Alarms
-
In T3, an AIS alarm is supported only in the framed mode and not supported in the unframed mode.
-
When the T3 RAI alarm is asserted, the propagation of the RAI alarm is stopped on the T1 interface. Also, the Interface Descriptor Block (IDB) state change is skipped for lower layer RAI alarm.
This behaviour is applicable for the following interface modules:
-
NCS4200-48T3E3-CE
-
NCS4200-3GMS
-
NCS4200-1T8S-20CS
-
NCS4200-1T8S-10CS
