Also once the retransmission changes from high to low, does this trigger the SNR to drop to 3db from 6db at the same time? Are the two correlated?

?

Sorry just noticed this. No they are separate, but both can change together. The line doesn't go straight to 3dB, it moves in 1dB increments, usually a couple days between each change. Every line is different though.

This truck works most times, but not always. If no change after 10-11 days it prob isn't working. It often starts DLM doing it's thing within a few days though.

Further to the excellent advice from @John83, the Telnet command does not survive a router re-start so if you re-start the router before the RETX has adjusted you need to re-enter the command.

I carried out the procedure last February and it took 3 days for the RETX high to revert to RETX low.

Just to clarify when you said router do you also mean the HG612 FTTC BT modem too?

Also noticed since I've throttled my sync speed to 40 mbps with executing that command ... the BRAS has also lowered down to 37.05 Mbps. Is this normal?

Yes. The BRAS is a percentage of the sync speed.

Currently it's around 92% of sync speed because of Retx high.
If it changes to Retx Low then the BRAS goes up to just above 96% of sync speed.

Yes. Rebooting the HG612 will clear the cap on the line.

Nice! The BRAS number I should be keeping an eye out for is ~38.8 Mbps (97% of sync speed to identify if Retransmission has has changed to low) ... I'll keep an eye on that!

Also for the 3db target ... once the retransmission to low eventually happens, should I keep the line capped to 40mbps or cancel the throttles? Right now the SNR is quite high, set at 10db I think, as the cap has been set on the FTTC modem.

It shows you the current SNRM, not the set target. Yours is high because of the cap. The SNRM you see won't change because the sync is capped.
If your target SNRM is lowered by the DLM you will see a resync and the max rate will go up.
So watch for a resync, from any resync watch for Bearer 0 INPREIN changing from 1 to 0. Watch for the max rate going up a few Mb.

Refund ... when you say max rate you mean a refund on the SNR right - so it should go higher than 10db? Can't be sync as that's overridden and throttled so they can't change that.

That was a typo

Just auto correct making me look like an idiot. I meant resync not refund.
