Hi, dear user.
You can configure the following parameters to determine the fast path mode:
Set Maximum interleaving delay downstream/upstream to 0.
Set Maximum INP on downstream/upstream direction to 1, which indicates that no protection is enabled.
Set Minimum rtxratio/rsoverhead in downstream/upstream to 0.
For details, see the following command configuration example:
huawei(config)#vdsl channel-profile add
{ <cr>|profile-index<U><2,1024> }:
Command:
vdsl channel-profile add
Start adding profile
Press 'Q' to quit the current configuration and new configuration will be

Hopes can help you.
