Yes, indeed I did have an engineer last Thursday afternoon. He was very thorough checking my wiring up to the DP in the building. He found a loose or disconnected wire at the DP and reconnected that. He then went to the street cabinet, and apparently found something else 'of concern' as he put it, and then on to the exchange where I think he found something else that 'wasn't quite right'. He assured me that everything to do with the phone side of things was A OK, and that if I had further problems, I should insist that a specialist Broadband engineer gets involved. My ISP ( O2 ) insist on running a further 24 Hour test on the line and I have got to call them again in the morning. I did explain that this 24 monitoring malarkey has already been carried out twice to my knowledge, but I think I was talking to a script reader rather than a proper 'techie'.
They set the target SNR to 15,as part of this monitoring. At least the line has stayed up all day so far.
Bring back my 15M sync with 6db NM @ 29.5 Attenuation.
I think something is seriously BROKEN, but convincing an ISP of that ain't easy. They told me this morning that as far as they could see from their end I had had no disconnections, but the line was up and down like the proverbial lady of the nights 'underthings' from around 3:30am. Sometimes it would stay up for around 2 or 3 minutes, other times up / down / up / down.........
Any advice would be most welcome

The explination from the engineer sounds suspect to me
. On a IDC connection you cant have a loose wire if dry (apart from a quante krone), its either terminated or not if it was dis then your phone service wouldnt work.
My guess is the engineer ran the pqt test from the cab for a pass so he can prove he fixed the circuit.
Did the engineer bring a next gen tester into your premises, or his laptop and hawk?
You may need a SFI visit which the engineer will be broadband trained.
The 15db snr will be more stable with a fault.
To add your metalic pathways 'pair' quality may pass a basic line test, however an in depth test from a BB engineer will look for issues that the basic tests will show. The important parameters on a pair for adsl2 would be Resistance balance >97-98%, AC balance >55db, Capacitance balance > 98%, DC voltage < 3v & Insulation resistance > 1 meg ohm.
So you can ask the engineer next visit
