General question on DLM

I have a general question for the techies on how DLM works, to help build me understanding.

What are the specific sync speed band values used by Openreach, and are there any other telltale signs banding has been applied? (a high SNR for example?)

Are any other changes of profiles applied with this? I seem to recall something about a BTW IP profile being applied at the fibre cabinet that sometimes gets stuck?

Thanks

Have a read of this https://kitz.co.uk/adsl/DLM.htm

I seem to recall something about a BTW IP profile being applied at the fibre cabinet that sometimes gets stuck?

It's more usual for the BT profile changes to not be communicated to PN and for the 'Current line speed' to get stuck. The good news is that this no longer has any effect on most accounts, only those with static IP's ( or the Broadband firewall enabled ) are now affected
