mscLpSdhPathLopAlarm

Module: Nortel-MsCarrier-MscPassport-LogicalProcessorMIB

OID (symbolic): Nortel-MsCarrier-MscPassport-LogicalProcessorMIB::mscLpSdhPathLopAlarm

OID (numeric): 1.3.6.1.4.1.562.36.2.1.12.15.2.15.1.1

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This attribute displays whether a Loss Of Pointer (LOP) alarm state has been entered. An LOP alarm state is entered when LOP defects have been observed and accumulated for a period of 2.5 seconds +/- 0.5 seconds. An LOP defect occurs when no valid SPE or VC pointer was received in 8 contiguous frames. If the LOP defects are intermittently occurring, the LOP defect accumulator is decremented at a rate of 1/10 of the incrementing rate (alarm integration ratio of 1/10), with all measurements based on a 200 ms polling cycle. The Path component goes into an operational state of disabled until the LOP alarm condition is cleared. The condition is cleared when no more invalid pointer has been reported for 10 seconds +/- 0.5 seconds. The lopAlarm attribute is always set to off when the Path component has been locked and left offline by the operator or when the Path component has been suspended since the parent component has been locked.
