You're spot on, but can anything be done about it now, short of snipping the wires coming into the house!

Are you connected to a Huawei cabinet, meaning that G.INP is available to you?

According to the supplied stats download G.Inp is on. It does look like a banded line.

Ah yes, misread that. Thanks

All you can do is wait , the DLM can take a long time to revert your line back to what it was before.
The line might have a problem with crosstalk or some other problem that might not be easy to find , for example the wet weather we have had might have made the pair to the cab damp or even the cab it`s self could have an intermittent fault.?
It took the DLM 4 months to sort my line out after a power cut about a year back.

4 months?! I'll put a note in my diary for 2019 to check.....!

I am not kidding, that DLM is a pain once it gets at a line it never seems right again imo.
The trouble is the darn thing does not know the difference between a line fault and a simple power cut.
Personally I do not see why it is needed as a good line will always return to the way it was before a cut of power.
And if there was a real bad line then the DLM is pointless anyway.?
The cabs themselves can cause the DLM to trigger too because all motors [fans etc] cause interference and so does passing traffic if the cab is near a busy road.
IMHO they could do with more shielding in the cab to stop internal EMI [Electric Motive Interference].
Getting of the soap box now.LOL.

Currently, DLM seems to be exceedingly reluctant to ever remove banding. And considerably keener to put it in place too.

There's a good chance that you need to get Zen to organise a DLM reset, justified as a consequence of the previous voice fault fix. It'll need an Openreach engineer appointment.

The current likelihood is that a DLM reset will initially start on an interleaved profile, so your speed wouldn't be likely to improve, and your latency would get worse. Then, in theory, it would swap back to fastpath after 2 days, and then, eventually back to G.INP. That process and timing depends on error rates, and predictable DLM behaviour.

Unfortunately, DLM is not currently behaving predictably, and you run a risk of finding yourself stuck interleaved with higher latency.

With DLM in its current guise, I'm not sure I'd recommend chasing the extra few Mbps right now, unless you really, really need it.

My line had was banded at 67,000 then 60,000 kbps, even with a 10db noise margin, the 67mb banding was there for a year with a 7-8db noise margin, the 60mbps banding was about 5 months with a 9-11db noise margin.

It never got better, only worse with the next fault that caused the 60,000 banding in the first place.

IMO banding virtually never gets dropped without a DLM reset.

I think I have 60,000kbps banding. I was stuck exactly on it for ages, through several re-sync's. Now I can't get to it .
