Module: ZhoneGR303-MIB
OID (symbolic): ZhoneGR303-MIB::igCrvTmcState
OID (numeric): 1.3.6.1.4.1.5504.4.3.1.7.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Time-slot Management Channel (TMC) state indicates when the line is off-hook.
Valid states are inService and permanentSignal. The default value is inService.
A line in a permanent signal condition initiates call clearing, during which time the RDT disconnects the RDT line unit from the DS0 (time-slot) assigned to the call, and continues to monitor the line. The RDT will report the return to on-hook status.
What is igCrvTmcState?
Reports whether this CRV's Time-slot Management Channel state is inService (on-hook, normal) or permanentSignal (the line appears stuck off-hook). A permanentSignal reading triggers call-clearing on the RDT side, which disconnects the line from its assigned DS0 while continuing to monitor for the line returning to on-hook.
