I may be wrong but I still think there is a loose connection and room for improvement! Hope springs eternal...

I hope your right for your case, but...... if you're pinning your hope on it being a loose connection and that it will go back to the attainable speeds (that are boosted for a short time) I feel you will prob be dissapointed, My issue was sorted earlier this week and it was a loose connection at the cabinet and I got no extra speed and I also still get the attainable boosts every now and again that I did before.
You definately still have room for a speed improvement though, especially if the DLM decides to remove interleaving on your line.
All lines are different though and as you say Hope springs eternal.
Good luck anyway.

No, for that to happen for sure there would need to be a reset of the DLM I believe? Did you ask for or get one after the repair?

The OR DLM will normally add or remove interleaving as it sees fit.

Yes but I meant a reset is needed after a line fault has been fixed to get a higher profile back ? Or not maybe? Or is that a separate operation? Or...

Sorry, I was having brain fade and mis-read your previous post.

I think it removes banding after quite a while. Ideally the engineers have it reset when they have fixed the fault.

Thanks and that's okay as it's all getting very confusing ...

I'll leave it as is for now but if the noises on the POTS get worse, it'll give me an excuse to report a line fault maybe.

If you look at that you can see that the Signal Attenuation is a lot higher than your line attenuation. It is believed that as D2 contains the tones that ADSL uses that the higher attenuation on the signal over the line is due to crosstalk if that's the case they yours is very high (mine is 18.4 line and 21.9 signal)

Well plusnet have tested my line and I have to report that there is nothing wrong with it (well there wouldn't be would there if it's intermittent), however the most interesting thing of all is that the tests show that I have no crosstalk whatsoever .

it'll give me an excuse to report a line fault maybe.

If you raise a 'noisy' line fault, then the engineer won't be doing a DLM reset on your FTTC service.

Yes thanks - that is then not a an idea to use.

However, am I right in remembering that a drop of 25% in line speed over 14 days counts as a line fault to BTW? At the moment I'm at 24.79% over 12 days!

What are your thoughts on a gel crimp(s) being the problem? There was another little spike up and then down then back up again this morning at around 11:00 on upstream.

Plusnet seem reluctant to do anything - they consider the line pretty perfect after testing it...

Thanks

I had a 30% drop in speed (from 72 Mbps to 50 Mbps) in about 3 mins and my ISP raised a ticket with Openreach a week later. The engineer came out tested the line, said it was OK and the line could never sync higher than 50 Mbps and went. Probably being 2:30pm on the day of the FA Cup final may have had some bearing on the visit only lasting 15 minutes.

Complained to my ISP, they got on to Openreach to get another engineer out, the same guy that came before turned up, tested the line. Made a call to some department and mentioned that the "customer said the line used to sync at around 72 Mbps", ended the call and said there is no record that the line has ever synced higher than 50 Mbps and left.
