But is there any procedure to ensure that resets are done where a hard fault is corrected?
My impression, based on ADSL lines, is that there is not.
ADSL experience is completely irrelevant as it is a completely different DLM owned and run and managed by BT Wholesale. It does have banding, but not the same sort of banding as the Openreach DLM used on FTTC.
An IP Profile on FTTC however is stiil a BT Wholesale thing. Completely independent of Openreach DLM which is what controls the line connection settings. The BTW IP Profile on FTTC only affects the throughput, not the connection speed, and is nothing to do with FTTC banding.
On BT Wholesale ADSLx circuits there is a procedure. ISPs can trigger a DLM reset, but whether it is a complete reset or just the SNRM I don't know. I think a lot of ISP frontline staff don't have the authority.
Kindness isn't going to cure the world of all its awfulness but it's a good place to begin. Daisy Ridley.
