In reply to a post by RobertoS:
the DLM takes over from there.


Hasn't DLM been deactivate by BTw now due to patent infringemen??

Read the last part of the article:

Although BT was disappointed with the ruling, we have made minor changes to our programming which means these two decisions have no material effect on the operation or performance of our networks

Sounds like it to me. If they didn't I expect it would have been much discussed.

Well Plusnet just attempted to do change but couldn't as an SNR change was done 8 days ago so got to wait till Friday!

Will Update you all on Friday to see how it goes!

Personally, with a line that length I'd more more concerned over stability and drop-outs than squeezing the last few hundred kbps unless it's causing problems in use. A long line is rather more sensitive to noise changes than a shorter one. That said, personal choice, but tuning everything to the n'th degree might not be the wisest thing to do.

I completely agree with that ...... smile

Well I've been assured by an Openreach Broadband engineer the line has more potential in it, I've been speaking with Plusnet and they are willing to give this a go.

I'm being swapped from an 8mb product onto an ADSL2+ product, and then on Monday my target SNR for downstream will be set to 3db and upstream to 6db, my interleaving will also be removed,

Then I and Plusnet will be monitoring the line for errors and issues and will act on it from their, I'm pretty confident that the line has more upstream sync speed in it, and maybe another 3-400kbps downstream but if I notice any issues or any significant error rates being reported I will be requesting that the lines SNR targets are set to 6db for both up and downstream and that the lowest interleaving setting is set to reduce them.

The worst that can happen is the line ends up slowing down until it can be reset to more stable settings.
