Weird stats but good to see.
You are still on ADSL, but probably on IPStream Connect, which runs it through the ADSL2+ system once it gets past the DSLAM. Alternatively you are now on an ADSL2+ DSLAM and your circuit configured down to ADSL.
With that attenuation you might get a bit more on ADSL2.
I've a feeling your bad speeds might have been on ADSL2+, which frequently results in a 3dB increase in attenuation. In most cases modem and MSAN software designers have failed to compensate for that, as it's rubbish.
I say that because what we see is an average attenuation across all the frequencies, and given the extra range of frequencies on ADSL2+ and the higher ones attenuate more, of course the average rises. The sync negotiation clearly takes the average into account somewhere, but if there is no way you will be able to use any of those higher frequencies then the average of the ones you can use should be taken instead. Or at least, the average of the ADSL ones.
ADSL2 uses the same frequencies as ADSL but better, and the attenuation is the same as on ADSL. On your attenuation I'd expect the resultant sync to be roughly the same, but as I think I said in my earlier post the only way to see is to try. However if your line has been configured to ADSL (G.DMT) then you won't be able to try ADSL2. At your end you can only force a lower level, not a higher one.
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
