Speed increase again today but it doesn't look like I'll be getting 16Mb, the NM has certainly closed a lot even with just a Mn increase in upstream sync;

Noise Margin 8.6 dB. 8.8 dB

Give it time, as Mr Saffron said, "with Sky the speed increases in steps, and their power management means that you cannot use the usual estimate and SNR margin rules."

It's possible you may get a downstream 16000Kbps sync with a 9dB SNRM for stability or a bit faster at 18000Kbps with 7dB SNRM as I believe RobertoS suggested in due course

Thought I would post today's line/connection stats, we are below the 7db target for Sky but read elsewhere that Sky can go as low as 3db since an update last year.

The only time I've got it around 2.5 - 3db was using the SNR Tweak on the Billion 7800n, in fact I managed to get it to 0.8db and was still stable but I was next door to the exchange at my previous address....

Looking good - more than 3000Kbps increase in downstream sync speed and SNRM down to 6dB, another 3000Kbps and you will reach your benchmark 16Mbps

Thanks for posting the stats: it's really interesting to see how your connection is being adjusted for optimal performance.

I thought it would be good to post the daily stats to show others how Sky operate the 10-day line testing phase.

I know it was something which I was looking for on these forums prior to posting.

The adjustment seems to take place once the line is quiet with no activity, once everyone has gone to bed and shutdown the puters, within an hour the new rate takes affect. In our case its between 0200 and 0300 once daily......

I'll post more stats on a daily basis, hopefully others will find it interesting to see how its working...

Yes, hopefully others will find it both interesting and informative.

I went onto partial LLU (uno TTB) more than a year ago - from "the word go" I was on a 6dB downstream SNRM, ~13500Kbps sync interleaved with a 37dB attenuation and it has stayed solidly like that ever since. It seems the Sky LLU kit has a much more gradual way of doing things

Normally, looking at my last set of stats I wouldn't expect anymore from Sky. In fact, I would expect a little less while they get the SNR back to 7db but as MrS says, Sky work differently to other providers...

I'm interested to see how much more I can achieve without tweaking the SNR...

All we can do is wait

With the speed capping used by Sky, doing things like tweaking SNR margin locally usually has no effect

The way I got it to work was to tweak it and then telephone them saying that it looks like I have a lot more SNR available and then they would adjust. It seems that when its tweaked my end it they see that there is still enough available and adjust accordingly.

Then once they adjust the profile the tweaks take affect
