No I am not on interleaving - I am just leaving the line as is at the mo, and see what happens.

Yes, the post got garbled - the column headers need moving along so the last 'fast' is over the last column.

The techie did say that there must be some other issue on my line that ADSL2+ cannot handle, hence the reason to test again on ADSL after the BT engineer *repaired* my line (remember, before the *repair*, I was still getting issues/disconnects/resync's with ADSL).

Anyway, I don't get much more on ADSL2+ anyway, and 6mb is fast enough for me (and I still have a decent upload figure)

OK, if you are happy with that, then fair enough.

However, personally, I would always be concerned about an underlying line fault and until the line was stable on ADSL2+ (8640Kbps, 6dB SNRM on a 41dB downstream attenuation) I wouldn't be 100% happy...

Well, sometimes beggars can't be choosers if you like.

Years ago when I had ADSL first installed, it was great - super fast and stable as anything - I think I used to sync at around 7900. Then about 6 years ago(?) some JVC idiot up the road whilst digging up the road cut through the phone cables, disconnecting my street and several others around me. It took BT about 4 days to repair everything, and since that time, I could usually only sync at about 5400. So what I have now (if it lasts ) is better than I had.

And also, I doubt BT would dig up the roads etc. just to fix my line

Best of luck with ADSL1

It's getting better... seeing as SNR was pretty stable, I changed the Cisco 'dsl noise-margin' option to '2' (forces modem to sync 2dB higher, I did set it at '3'):

I done this 1 hour 10 minutes ago - errors are now a LOT lower, and sync speed increased slightly.

Keep an eye on the reported downstream SNRM if there are no re-syncs this evening or over-night - I wouldn't like to see it drop to below 3dB after sunset.

Error rates look minimal at the moment

Yeah, I am going to monitor until about 21:00 tonight. The graph makes interesting reading, so I will post it here later.

But finally it really looks like my line is fixed. I was wondering if BT done something when I got reset, as Enta said it takes 24 hours, so I should have had a reset around 15:00 today, but it happened at 02:21 this morning - I wonder if they changed something on my physical wires?

This is after 2 hours on 'dsl noise-margin 2' - that's more like it

Must have been OR working on night shift LOL!!!

To be honest, that might be as strange as it sounds. They must have engineers working overnight in the exchanges sometimes doing upgrades or whatever, and I know from experience that sometimes the job gets dome quicker than thought - so rather than sit around for a few hours, you find something else to do...
