It looked like Starman has a manual reset of DLM after his recent line fault. I think the timing of the reset on the 21st & the recent ASSIA/BT dispute means that he has escaped the wrath of DLM and under normal circumstances, DLM would have caught up with him by now.
I suspect your line has a high ILQ rating based upon what ever happened in your first few months of FTTC, so therefore it will take a lot longer to recover. Personally I think the recovery procedure is tough and way too strict.
Im also unsure what profile BTretail provide their lines as.. theres only Plusnet and Zen who have been open and said they provide on 'Speed'.
BT may provide as 'Standard' which is the default setting. There is rumour that TT customers with TalkTalkTV are provisioned on 'Stable'.
Customers provisioned as Standard or Stable by their ISP are going to take a lot longer to recover and get interleaving removed than those on an ISP which used 'Speed'
