Don't know sorry.
I had a gradually worsening fault, to the point where in the end it became quite a nuisance, of the broadband continually losing and regaining sync for hours at a time once it started doing it. (Fortunately on O2 LLU so no long-term effects). By continually, I mean the re-sync time of ~20 seconds was closing matched by the 20-30 seconds before it dropped out again.
The cure was to run the quiet line test for several minutes. That stopped the disconnections almost immediately, but had to be kept going for a while. Immediate termination of the test let the problem come back straight away. By gradually worsening, I mean it started happening every week or so, and ended up as several days a week.
My gut feeling was it was E-side, with the views of several OR engineers hunting for usable pairs at my cabinet supporting that. I'd already had a pair swap due to the phone line becoming very noisy, and the new pair was 700Mbps slower than the first one. I didn't want another swap, though it was beginning to look inevitable.
This was a major (but risky) factor in my move to FTTC, thus eliminating the e-side for broadband. A couple of the engineers posting on these forums reckoned that if it was E-side the FTTC would be insulated from it. Which it is, I'm pleased to say. The cost rise from £5.nn to £23.nn, plus ~£90 setup and a £26 router was a bit of a choker but I don't regret it. Nor do I regret my move a year later to PN, at much lower cost. £16.49pm - though I have now upgraded.
