Parameters
max-rtt value: Maximum round trip time (RTT) to be set. This argument ranges from 1000 to 25000 (in
TQs). The system default is 13524 TQs.
Description
Use the max-rtt command to set the maximum RTT from the ONU to the OLT.
Configure the maximum RTT from the ONU to the OLT only when necessary. The relationship
between the RTT and the distance (in meters) from the OLT to the ONU can be expressed by the
formula: RTT = (Distance + 157)/1.6393.
The max-rtt command is applicable to unregistered ONUs only.
For details about RTT, refer the related sections in the operation manual.
