it's quite capable of putting you on a banded profile

Ah, didn't know that - tread carefully indeed

EDIT: Having said that how much is the BT DLM affected by errors - as opposed to drops & re-syncs?

I know it's C&W but my target SNRM has dropped despite relatively high error rates (see previous post) but sync itself is rock solid (perhaps it's keeping me from dropping back the final 3dB).

I don't recall the details from when Demon used the BT ADSL offering but I have always needed to tweak the SNRM to get a decent speed and IIRC the target SNRM was stable (but can't recall whether it was 6dB or 9dB, the latter I think).

Like iwish mine shot up due to a dodgy cable (in my case the modem lead), so it was to get the margin back to give me a decent speed rather that waiting for the DLM to do it (it took months in my case).

Hard to tell.

The BT Wholesale DLM applies to all ISPs providing their services. But LLU DLMs are entirely down to the individual supplier's views on how they want it to operate.

Actually that isn't quite true. It also depends on the programmers' ability to implement those requirements.

It's not so bad now (the one used on FTTC actually seems quite reasonable if you accept the necessity for the damn thing in the first place), but at one time I'd have said that it depended on the ability of the latest work experience kiddie to write programs

I have found Indians with such things in their CV with a bit of Googling

Just after buffalo hunting and paleface scalping?

Actually, if you'd said "cowboys" I'd have understood it.

well my line has reduced the crc rate over the past 24 hours to less than half of what i would get
SNR is still at 12 but bt being the idiots they are have stuck me on a 1mb profile now
My isp have no idea why bt are playing up with my line, and say my line is looking good and clear
I have now lost all hope with bt and the almighty DLM

Its my extension that has become damaged

so there was an actual problem at the root of all this ?

we pulled the extension out and found no damage
But we still put the router into the master socket just incase
line stats from master face plate
Total Uptimes (From SF counts):
WAN: 1 days, 01:16:54
LAN: 1 days, 01:16:54


CRC: 313
LOS: 0
LOF: 0
ES : 163

could just be how the cat 5 cable was run but don't see how
my last stats from said cable was about 185 crc errors a day if you work it out over that 6 day period
