It's shocking the difference in BQM graphs between cable and FTTC, must be such a relief to be on something decent.

Hehe, not at all
D-Side is 300M, most of it is aluminium though, the cab serves 600 properties and there are at least 90 active FTTC circuits as of about 1 year ago.

I didnt do any graphs before the attainable dissapeared and I am not about to start resyncing to see if it comes back, I will only do that sort of thing if my actual sync drops below 79999.

Cool thought you might seen as your logged in via telnet in one of your screenshots. Was just putting it out there.
No no I'm not suggesting you resync, I'm saying if it hasn't resynced you can still grab the stats because they wouldn't of changed yet for everything so it's still a sort of before snapshot, then when it resyncs grab them again and compare. If the drop is accross the whole range it's likely due to crosstalk, if it's concentrated at specific frequencies then it's interferance. Of course if your not interested then there's no need to bother. If it did go tits up though it would be good to have a before snapshot so you have some proof of past performance should you need to pursue a fault.
Anyway, you still got plenty of spare so enjoy it

So far it's stayed up for 2 weeks at full sync despite the SNRM dropping to 3dB. Still, stable at 80Mb sync aint bad for someone who was predicted 53Mb. But the 110Mb attainable without crosstalk gives me hope for 200Mb when 30a + vectoring come out.

Interesting, it's supprising and frustrating how well it can hang on, mine was at 5.5 for nearly a month without any increased errors or instability before DLM decided enough was enough, the retrain reason was negative margin. It's probably only a matter of time before it reduces you too.
If the default SNRM was 3dB it would have no trouble sustaining the full sync with interleving off. Maybe they will drop it in the future if only just for the marginal lines.
Vecotring would no doubt help but I don't hold much hope for it any time soon, doesn't it need new line cards and CPE?
