My stats on O2 line capped to 8Mbps (line does approx 17Mbps uncapped). Netgear router.

ADSL Link Downstream Upstream
Connection Speed 8188 kbps 1087 kbps
Line Attenuation 20 db 4 db
Noise Margin 14 db 6 db

My netgear reports the Target sm even if i switch to the be value capped 12mbit mode when i know there would be spare snr showing with other isp's , strange that they would configure the dslam's in that way, i mean why bother doing that? i see no reason too,

There is no reason, it is just poor engineering, throwing away overhead in noise margin for absolutely zero gain.

What speed do you sync at anyway, and what other ISP offers an up to 12Mbps connection? (Other than perhaps a reseller of Be, in which case I would expect the Be behaviour in this respect).

Zero gain, have people looked at the power levels too?

Some CPE and DSLAM combos are good at backing off the power level, and if the noise environment requires it, then raising it again, before requiring a resync.

Keeping power levels lower can help avoid cross talk. Alas lots of CPE don't report it, or appear to have bugs in what they display.

It isn't power levels as the bit loading hasn't changed much.

I don't think it's a display bug either.

It's a line fault. That really is the SNRM and max sync at max power.

The line syncs at a higher speed uncapped than capped therefore your conclusion is false.

mmm, using a reseller maybe , but via a wholesaler no, as they have there own network link to the be/o2 network pop's so can use pppoA my sync btw is 16mbps on pro 18.5mbps adsl2+ i also used to get a higher sync than i currently do, at a higher target snr & the attenuation is around the same @ +0.5 db just another observation the method that be use to connect or should do, (IPoA) although it can sync no traffic will flow(no internet) the difference in sync and throughput seems a little higher that my old pppoa connection

You conclusion is based on minimal stats, therefore is wrong.

Your response is argumentative and illogical.
