Can you opt out of DLM?

[#1]

I’ve recently had an engineer round and he reset my connection which I was happy with. Now DLM has reset it and my latency has gone from 14ms to 30ms. As I like to game this is an issue for me. So I’m wondering if it’s possible to opt out of DLM?
Cheers

On an ADSL connection, it used to be possible ( not sure if it still is? ) but on FTTC its not possible.

I have FTTC ok no problem
Thanks

On FTTC there are three things that you can mess about with to influence DLM

1. You can ask Plusnet to change your line's "Stability Profile",  DLM might see a more stable line and reduce the level of interleaving (causing your latency), see  https://kitz.co.uk/adsl/DLM.htm#dlm_stability_level 
2. You could get a VDSL modem that supports setting an offset on the target SNR, and by artificially increasing the noise margin, your line will trade off being slightly slower but be less susceptible to errors, and as a result DLM should eventually reduce the line latency.  This only works on the 'download' direction.
3. If you have a Broadcom chipset modem that you can type a command line at,  some allow you to artificially set an upper limit to your line speed,  so if you set your maximum line speed to something slower than would normally be negotiated, then this has the side effect of increasing your line's noise margin, which improves stability, which again DLM will eventually reduce latency.  This works on either or both upload and download directions.

What modem and/or router are you using for gaming ?

What results do you get for "Bufferbloat grade", Latency, and Speed, from this test - https://www.waveform.com/tools/bufferbloat

I used to just use Asus dsl-ac68u for everything. Which was fine but up until recently I have been getting line changes.
After doing my research it was mentioned then Asus chipset didn’t agree with BT.
So I now have the HUB2 as the modem and my Asus does the routing. Bufferbloat is A
- Latency was 45 and speed 30.

Oh, there's not much you can do with a Hub-2 for DLM hacks, but I understand that it makes a good modem.

Have you considered 'upgrading' to SoGEA ? - it will probably be cheaper than FTTC !

When I moved to from FTTC to SoGEA, having the analogue phone disabled on my VDSL line reduced my modem error counts, which made DLM increase the sync speed by about 6Mbps and theoretically could reduce your latency back to previous lower values.

The other thing you can do is ensure your BT Master Socket wiring is as optimised as possible,  i.e. remove any extension wiring, and plug your modem in to the TEST socket behind the faceplate using the shortest possible DSL cable (I use 24-AWG  50cm twisted pair RJ11 to BT431A  pure copper cable).

Anything you can do to reduce DSL noise, will help DLM

Hi thanks for your reply,
I have just transferred to SoGEA.
I will most certainly try using master socket using that cable you specified although I am having trouble sourcing it!
