| Description | Indicates the state of the CID.
'cidStateActive' : The CID is in service and operational.
'cidStateFailed' : The CID is in service but not
operational, e.g. because the PVC
that the CID belongs to is receiving
F5(Operation, Administration and
Maintenance Flow) level alarm.
When VISM sees alarm on a CID (network side) sets
this object to 'cidStateFailed', and an AIS will
be sent on the ds0(Time Division Multiplexed
voice channel) that this CID corresponds to.
If the whole PVC is in alarm then all the CIDs
on that PVC will be set to 'cidStateFailed',
trapVismChanFailed trap will be sent and all
the ds0's that corresponds to each of the CIDs
on this PVC will be in alarm.
If VISM sees an alarm on a ds0 in a line then
an RAI(Remote Alarm Indication) will be sent
on the CID that corresponds to this ds0, however
the CID will not be put in failed state. |
