DLM reset / banding removal required

After a week without a working telephone line since the storm on Monday 28th October, I now need the banding removed.

[tt]US Connection Rate:    804    DS Connection Rate:    285
DS Line Attenuation:    56.2    DS Margin:              18.1
US Line Attenuation:    36.6    US Margin:              5.8

Re: DLM reset / banding removal required

Hi ejs,
I've submitted an SNR reset for you which should remove the banding, though it doesn't look like it's been stable for that long:

Hope it all goes smoothly, should take effect before lunch.

Re: DLM reset / banding removal required

I see the banding has been sucessfully removed:
[tt]US Connection Rate:    804    DS Connection Rate:    3750
DS Line Attenuation:    58.2    DS Margin:              5.9
US Line Attenuation:    36.5    US Margin:              5.6
[/tt]
The BT engineer fixed the telephone line yesterday. I'm told it was fixed by disconnecting (in the BT66 junction box outside) the wiring for an unused socket . And it's not even the first time that the voice line has died and BT have visited to re-do the wiring in that box this year. Anyway, it should be fine for now, thank you.

And now of course at 18:30 the IP profile update happens at Plusnet and somewhat unhelpfully sets the speed to 0.2 Mb.

Hi ejs,
The profile updated on our systems to reflect another change in the BT profile.
That seems to follow a resynch at around 18:30

I'll try another SNR reset for you as we've seen a period of stability (again not that long) if that doesn't resolve things within the next few hours you'd be best off raising a fault: http://faults.plus.net

Re: DLM reset / banding removal required

There was no resync at 18:30 - see attached graphs - the reconnect at 18:30 on your graph was just the IP profile updating on your system to 0.2.
This reminds me of the old days, when the sync speed might increase before a few days old lower IP profile eventually changes on your system.

Re: DLM reset / banding removal required

I've just updated the profile for you as the sync speeds appear to be holding out fine.
It'll take a few days for the DLM information on our suppliers systems to update so that we can see whether or not the line has improved.
