Can anyone point me to a link that gives "official" info on the DLM Quantisation project? Please!

There isn't any yet.
On FTTC your BRAS profle is calculated on the fly every time you resync, so if you have a different sync rate each time then the BRAS profle will always calculate to match the sync rate. On ADSL and ADSL2+ it wouldn't change on the sync but up to 1-5 days later. With BRAS Quantisation, ADSL2+ works the same as FTTC so the BRAS profile is calculated each time the line resyncs not 1-5 days later. We fed back to BT that this should be the way that it works and they listened and changed it.
At the moment, only 40% of the ADSL2+ MSANs support this, the remainder will support it in June and the full support will be complete by October. The intention is that rather than having to wait 1-5 days for the profile to update it will be done immediately and rather than having to be stuck with the existing profiles in 500kbps or 1000kbps steps any profile is now valid so almost everyone on ADSL2+ will see a small increase in throughput.
Full rollout is due in October when all the profile changes will be fully supported.

That is the most spectacularly amazingly positive thing you could announce on here - I'm amazed no-one has responded.
It wouldn't affect me directly, but it affects a lot of people - surely it has to be half the volume of work on the threads here (both explaining, and responding to).

On average, 250Kbps for those <9Mbps, and 500Kbps for those > 9Mbps. Certainly not to be sniffed at.

Does that include rollout of the Plusnet side of things, as well as the BT side?

Wow, as WWWombat says, that's fantastic.
It's almost a shame I'm not adsl2+ anymore (actually I never quite was, more ADSL1)...  The one thing I really didn't like on the meagre speeds I was on, was getting a sync of 1699, and only having a profile of 1500, or 2459 and only getting 2000.  For someone on such slow speeds, those steps seemed a bit large.
Well done!

We're just waiting for confirmation of exactly what is changing in the reporting side then we can look at exactly what we need to build on our side. At the moment I can't say when that will happen as we don't know the full details yet to be able to create a worklist of changes to make.

From my last BT speedtest it looks as though I have now been taken off the trial as the IP profile is now 4000kbps although the actual speed is quite remarkable

[#8]

I was taken off a few days ago.
But I'm back on again!

[#9]

I've been getting over 700kbps faster than my ip profile
very odd ha

Dave,
What about those on exchanges still waiting for a WBC update? Mine still does not even have an expected date.
So assuming my line/exchange is now handled via IPStreamConnect, does this apply to my line too?

[#11]

The quantisation software goes on MSANs and those are part of WBC. So I guess it won't be on IPSC where DSLAMs remain in use in the exchange.
