dot3MpcpRoundTripTime
Module: ZTE-AN-EPON-SERVICE-MIB
OID (symbolic): ZTE-AN-EPON-SERVICE-MIB::dot3MpcpRoundTripTime
OID (numeric): 1.3.6.1.4.1.3902.1082.500.31.2.1.1.10
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: An object that reports the MPCP round trip time in increments of Time Quanta (TQ)-16ns. The value returned shall be (round trip time in ns)/16. If this value exceeds (2^16-1) the value (2^16-1) shall be returned. This object is applicable for an OLT and an ONU. At the OLT it has a distinct value for each virtual interface.
What is dot3MpcpRoundTripTime?
This read-only value, in units of 16 nanosecond Time Quanta and capped at the maximum 16-bit value, reports the MPCP-measured round trip time to the remote peer on this EPON virtual link. An admin uses it to gauge the fiber distance and/or ranging delay to a given ONU, which the OLT uses for time-division multiplexing. For example, comparing round trip time values across ONUs on the same PON reveals which ONUs are physically farther from the OLT.
