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.

# Set the maximum RTT of the ONU connected to OLT 3/0/1 to 25000 TQ.
