How long does 3db take to start?

I had a lift and shift around 9.9.20 with a port swap by Openreach. DLM has intervened once by changing Interleaving from 4 to 8. But I am not seeing any movement on my 6db target margin. Uno my ISP has put through a DLM reset request but that was a few weeks ago, again no movement.

Am I waiting in vain?

Huawei DSLAM I am connected to.

Week, Month or never! Only DLM decided! If your sync rate 79993 u will not gonna see any 3dB because your line is on max 80Meg

Sync is 54. I had 3db all last year.

you need to update your signature. Perhaps remove all the sync details as they change.

Sig changed

As quick as 2 days after a DLM reset.

It used to be a couple days for G.INP to be applied and then another couple for the drop to 5dB but G.INP is now kept active after a DLM reset which knocks a couple days off.

It could change at any point but if it doesn't change within a few days then most of the time it never will.

Not sure who your ISP uses for backhaul but BTWholesale will reject any DLM reset request from your ISP if the line is within its estimates with no banding in place.
They are very unlikely to process a DLM reset just because the line hasn't dropped SNRM target.
Talktalk backhaul is likely to be the same if not similar.

How come I had 3db all last year and it changed due to a port swap? TTB is my backhaul.

The port swap sees the settings reset back to ‘out of the box’ ...

So is DLM stuck? I am not seeing any downstream Error Seconds just upstream.
