Hi Kitz & Black Sheep, thanks for your helpful responses. I have read them all. The problems with my line seem to be dynamic in that it's changing all the time. The last few days, it's changed for the better (or so it seems). The noise at night was dropping but only some of the time, not every night. Since 2/3 days ago, the SNR is going up every night & instead of dropping to about 6.4dB sometime during the day, it's not dropping as much. The noise during the day seems better, as the last 2/3 days the SNR has been at 6.8dB. At the moment I'm at 8.1dB with an attainable of 47,648. When it drops to 6.8dB, the attainable is 43/44Mb. Errors since the last re-sync have been negligible. 1400 of those US ES were caused by the re-sync (No idea why it does that).

I haven't spoken to the BT MOD since last weekend as I wanted to collate a weeks worth of stats to indicate why I don't think my line should have been banded. When the SNR dropped to 4.8dB that coincided with the interleave coming off & the speed increasing. Probably the increase of X-Talk/Interference pushed it down, as you said Kitz. The missing tones have almost filled in at the beginning but I'm still missing tones from 250 - 290
Since midnight, apart from FECs, there hasn't been any errors on the DS at all. What causes US errors? Are they something the DLM takes into account?

Thanks for all your help. I don't understand a lot of it but it's helping me learn
