In this post http://forum.kitz.co.uk/index.php?topic=14762.0     I said  they put my line on 10 training.

In above post I said I changed my modem after one day but I would like to try it again after four days out of ten.

Should I tell the isp what I have done or just let it get on with it's training ?.

I responded in your other post before I read this one.  :/

No I wouldnt bother, because then they may just reset the line again..  which I do not believe is related to the issues you are seeing.   TBH I thought the DLM was being pretty fair considering the amount of errors that you appeared to be racking up.

You really need to investigate what is causing the errors, and only when we are at that stage is there any point in getting the DLM reset.

As the boss said in the other thread, an SNR reset in your case is nothing but a 10 day waste of your time.

It pretty much doesn't matter what you do in that period because you either have a horrifically unbalanced line (BS, where are you?) or your 52 extensions are competing with half the ADSL spectrum!

Very easy for me to make assumptions sitting far away on a computer so apologies if this isn't particularly helpful!

I have run with all the phone extensions disconnected (by removing the NTE5 faceplate and using a filter to plug the DSL in ) for some time tonight and I find as before when I have tested the was NO noticeable difference

I can only use the modem stats .

With NO extensions.

With the extensions back and DSL plugged into NTE5 faceplate.

I dont know which is which...  but whilst still showing a bit of noise... the graph taken at 15:33 is the better of the two.  In fact tones 40 to 150 look quite good for a longish line.

The spike at tone 64 will be the pilot tone, so no need to worry about that. Even tones 150 -180 are slightly cleaner with less spread.

I was wrong it seems. They're not competing with half your DS tones but more like 80%!

Significant improvement on that QLN, well done for testing!
