Have I been put onto the wrong product?
Join the club.
You are on ADSL2 if you use about 1MHz bandwidth - the same as ADSL MAX
ADSL2+ if you have the capability to access 2MHz (approximately)
The majority of your signal will be in the bottom 1MHz anyway - but you are not going to get much speed improvement.
But you are still in training phase...

So what does that mean in layman's terms - the 1MHz and 2MHz bit? It went over to the faster upload speed last Monday so not much more training to go. 
Have now been looking things up via google and wonder if I should have a new filter that's ADSL2+ compatible. I've not seen it mentioned anywhere here that I should get a new filter but it looks as though that might let the full speed come up.

There is no need for different filters - the old ones are already compatible with any kind of ADSL.
ADSL2 uses a signal that occupies roughly 1MHz of bandwidth - which is the same as ordinary ADSL.
ADSL2+ uses twice as much bandwidth.

Not at all Asbo - after all it took ages for PN to succeed in getting the problem bumped up to BT Wholesale Manager level.
And it's just reared it's ugly head again, so it's a current ticket issue as well.

It seems that this fault is still existing.
It might be better named "Why have I been put on ADSL2 instead of ADSL2+?
I'm aware of several people with his problem, but unless you are
(a) Realise the difference between the two products
and
(b) Know how to use your router stats to diagnose this
and
(c) Be ver persistent
You won't get anywhere.
PN's fault checking for 21CN is identical for ADSL MAX(ADSL1)
Since ADSL1 and ADSL2 use the same bandwidth, no errors specific to ADSL2 or ADSL2+ are ever going to be found.
It is necessary to spend about a week bouncing stuff backwards and forwards until you get the threat about sending the boys round:-
Since this was a re-occurence of the same fault, I was able to write:-
Previously (apart from a few queries about progress reports), this was the latest stage before achieving ADSL2.

Quote I have further tested your line, but the BT testing service has still not shown any issues with the service.
Now this does not mean there is not a fault, but the only step we have left is to escalate this issue with BT.
I must make you aware before we do this, that if BT further investigate and confirm that there is no fault, or that the issue is being caused by anything at your side, then they charge a failed fault check fee to you, which starts at £144.00 +VAT.
Please let us know if you would like this escalating further.

Quote Can I refer you to your answer of 12/3/09 @ 14.24:-
===========================================
We are pleased to be able to inform you that a member of our Customer Support
Centre has now escalated your Question [number 27112413 ]
for further investigation.
The following comment was added to the Question
Jeremy,
Many apologies for the delay in getting an update on this issue. I have only today
received feedback on this issue from our account manager within BT Wholesale and
they have advised they have done some backend work to try and correct the issues you
are experiencing with your service. If you could let me know if you are still having
issues with the service so that we can get this further investigated for you.
I have also raised this issue with my line manager as the initial complaint i raised
for you with our account manager with BT has still not be answered.
Previously (apart from a few queries about progress reports), this was the latest stage before achieving ADSL2.
it's a trial so things like this are going to happen.
so i would like to thank axis-bbyw and the others right now for being the guinea pig's that will improve the fault finding process on adsl2+ for all us poor soul's on currently on non WBC enabled exchanges.
@axis. have you seein an increase in your downstream atten on adsl2 compared to adsl?
i ask as there is another customer on the trial that says they where getting 6mb on adsl but from info on pn test on his line now the atten/loop loss on his adsl2/adsl2+ line is 49db and syncin at 3000ish kbps which i would of thought if they had 6mb on adsl there atten would of bein lower when they where on adsl
his upstream seems capped so i adviced him to pm jameseh and wait for that to be uncapped before going deeper into solving his problem as you never no the reorder jameseh puts in might just sort the downstream out to. anything's possable it seems with adsl2+

My downstream attenuation has increased from 27.5dB on ADSL MAX to 34dB on ADSL2 to 37dB on ADSL2+
This is spread over 3 routers and several months, but matches PN's "loop loss" tests.
Noise margin has been all over the place - but DMT allows me to run a stable ADSL2 connection at 3-4dB Noise Margin.
Because there is a fault, I'm not using DMT and BT are pleased to give me a 8-9dB target noise margin
I expect things to go wrong on a trial - but I would also expect PN to fast track ADSL2 / ADSL2+ problems.
They don't appear to have any special diagnostics in place, other than "refer to BT Wholesale" if you push hard enough.

cheer up axis could be worse the guy in this thread has what seems to be a 15 or 18db target snr looking at his PN test's
Quote 8-9dB target noise margin

asbo breaks into song. all ways look on the bright side of life
I was ecstatic to get 8-9dB - at one point I was on ADSL2+ but with a 22dB noise margin!!!
PN said there was no such noise margin
