How do we persuade BTW/OpenReach to replace a faulty cable in the road?
They hide behind an outdated line specification for voice transmission which pretty well relates to dial-up speeds for internet access. If we complain, we are told that broadband is a "Best Effort" and nothing will be done so long as the line meets the voice spec.
OpenReach engineers openly admit that they are unable to find a fault-free D-side. The line is marked as "degraded" and the banding is lowered accordingly so that the range covers where the line currently performs on broadband.
To aggravate matters, the DLM seems to have an objective of zero CRC errors, which results in the line being trained lower and lower in speed, to the extent that it reached a point where it was 2Mb download sync, compared to other places in the same road where the user gets 7Mb.
Any bright ideas gratefully received.
