I have today, just before 4.00 pm, had a DLM reset which was arranged by BT Retail.
Story is that back in November I got carried away by the DGA4130 thread and obtained one. Had great fun setting it up as per the thread, but the end result was my line becoming both interleaved and banded. Straight back to the Draytek and despite 6 weeks of zero errors there was no sign at all of DLM relenting.
On Jan 3rd I recontracted with BT, and was pleased to see my synch was below the guaranteed minimum. Rather than raise this issue by phone, I opted to ask for help via the BT Community Forums. Although this is a customer to customer forum there is a "small specialised team of BT employees" who will on occasion pick up issues. I was hoping to have an OR visit so that a reset could be done. My case was picked up yesterday, and I received a message from the person who picked it up to say he had raised the issue with OR and would call today with an update. I checked the stats a couple of times this morning but no change. I received the call shortly after 4pm to be informed a reset had been done and my banding and interleaving removed - indeed it has.
We had a good chat about it and he confirmed that the reset had been done remotely, but also said that OR are controlling this extremely tightly, and when he submitted the request he had no idea whether it would be done or not. Definately a move in the right direction.
