This has been worked around for now. Used the BPL to trigger the noise and triggered a resync intentionally. Modem and DSLAM duly changed bit allocations to heavily favour downstream band 1 and reduce reliance on band 2 and especially band 3.

There might still be the odd correctable FEC as 10 dB is a tad low an SNR even for QPSK but it should be better. Pity there's no capacity to use BPSK on those really poor tones, would've helped a little bit but probably not worth it in the grand scheme for just an additional 4kbps per tone.

The line will probably remain banded until it is retired for a VM Business service in the upcoming months.

Hope this is useful to someone in the future - subject changed for easier searching.

The subject line has now been adjusted for all posts in this thread.

Thank you, Sir.

surprised you even was using one of these horrible devices ignition, would have thought you have known they not the best idea

For people who dont want to deal with ethernet cable routing indoors, the cables are covered in waterproof material so can be routed outside.

Indeed.

I'm using one 20m section of flat ethernet cable to cover one tricky run. That flat cable can be routed out through the double-glazed windows, as there's just enough room to get past the sealing strips.

The downside is that it is indoor grade, so it'll be killed by UV sooner or later. There's a backup cable waiting to be run out when this one fails.

Banded to the same sync speed as my line. Hope you have more luck having the banding removed than I've had so far!

Not attempted to get it removed: don't care, can't be bothered.

I convinced my ISP to get a BT Engineer out. I provided evidence that I had found and repaired a faulty modem so they where happy to send them out for a DLM reset
Speeds and g.inp back to normal in 48hrs from reset.

I'm quite aware of what they do and don't care.

Other things in the property to do, like upgrade the kitchen, living room flooring and looking into an extension, before I start messing around with getting Ethernet cables up 2 floors.

Neither am I going to start drilling holes in walls and climbing ladders to do it externally.

Until the broadband coming into the property makes the PLN obsolete I'm fine with it. Latency is satisfactory and it's delivering an aggregate throughput of 400-500Mb/s

This has now joined the list of things to do. A design has been done and the active equipment required drawn up as part of making the property gigabit Internet ready.
