Output from vdsl optn
vdsl optn
%% adsl optn FUNC [us/ds/bi [value/on/off]]
%% FUNC : ‘trellis’, ‘bitswap’, ‘sra’, ‘retx’, ‘aelem’, ‘virtualnoise’, ’20bit’, ‘status’, ‘g.v
%% us/ds/bi : upstream or downstream or bidirection.
%% ‘aelem’ and ‘g.vector’ are only on/off.
%% value : bitswap=0~2, sra=0,2,3,4, 20bit=0~2.
%% on/off : enable/disable.
%%
%% PS, some commands are only available for VDSL2.
%% some commands are only available for later modem code.
%% For G.Vector feature, CPE’s modem firmware needs to support VDSL2 G.Vector.You need to login in order to vote
May 6, 2020 at 11:49 am #7026I just looked at the DrayTeK 2760 manual and Cmd is the same for adjusting SRA ?
But does show cmd – adsl optn status rather than vdsl optn status options ? so DrayOS maybe older coding style/standard etc ?

May 6, 2020 at 12:00 pm #7027Right, while lunch brake I have few attempts but only command “vdsl optn sra bi 2” indicate changes as per screenshot, however after reboot SRA is still “ON”. Should I reboot or no?

May 6, 2020 at 12:23 pm #7029Did you use this to save cfg before reboot “vdsl savecfg ” ?
Yes reboot after entering cmd “vdsl optn sra bi 2 off” again and the savecfg cmd to save configuration
Fingers crossed

@Uk Sentinel
On my line not much difference errors wise with SRA off.
Did you consider to get BT to check your line or you prefer to play with modem first. 😉
