dot3MpcpSyncTime
Module: DOT3-EPON-MIB
OID (symbolic): DOT3-EPON-MIB::dot3MpcpSyncTime
OID (numeric): 1.3.6.1.2.1.155.1.1.1.1.4
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: An object that reports the 'sync lock time' of the OLT receiver in increments of Time Quanta (TQ)-16ns as defined in [802.3ah], clauses 60, 64, and 65. The value returned shall be (sync lock time ns)/16. If this value exceeds (2^32-1), the value (2^32-1) shall be returned. This object is applicable for an OLT, with the same value for all virtual interfaces, and for an ONU.
What is dot3MpcpSyncTime?
This reports how long the OLT receiver took to achieve sync lock, measured in 16ns time-quanta units, per [802.3ah]. A rising sync time can indicate a marginal optical link or clock recovery issue on that PON interface worth investigating before it causes registration failures.
