h3cDot3MpcpRoundTripTime

Module: A3COM-HUAWEI-DOT3-EFM-EPON-MIB

OID (symbolic): A3COM-HUAWEI-DOT3-EFM-EPON-MIB::h3cDot3MpcpRoundTripTime

OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.42.2.1.1.1.1.9

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: A read-only value 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 attribute is relevant for an OLT and an ONU. For the OLT there is a value per LLID

What is h3cDot3MpcpRoundTripTime?

Measures MPCP signal propagation delay in both directions (in 16-ns Time Quanta units). Operators monitor RTT to size bandwidth allocation windows and detect physical layer faults. A value of 4,000 TQ (64 microseconds) represents a reasonable distance; higher values suggest long fiber runs or poor signal quality.
