Mine is much the same including the date. Someone on the Plusnet community forum recently made a spreadsheet available which showed the soonest that 21CN would be available for me was 1/3/12.

With 21CN the IP profile is 88% of the connection speed. With my 6km long line with some aluminium that may be the biggest advantage of 21CN to me.

Hi

Based on the feedback and the data available folk like us on the ends of long lines will see diddly squat benefit from ADSL+2 or indeed it seems using an LLU service. I would be sceptical of any claims that we could see an improvement as the cynic in me says ADSL+2 needs better copper to work well and just maybe 'we' would get a worse BB experience by trying for ADSL+2???

The only way for us will be when BT Infinity pulls its finger out and does the FTTC to "our" exchanges. FWIW I see that various ones around ours in Surrey are or will be FTTC'ed..................................so feeling kind of left out

Oh, IMO you are right about aluminium being present! A ways back I chatted with a BT engineer working in a local roadside cabinet and he remarked that a large part of his job if remaking joints where the copper & ali meet and that the only solution was to pull fresh copper bundles but that would "never happen...." C'est la vie

RS Re whether ADSL+2 will be good for the limited increase we might get??? Perhaps CSC can advise if I was to opt for it when available but I get a worse service in respect of sync speed & actual download speed and more importantly a less stable connection could I revert back to ADSL Max without charge and expect a return of the sort of speed and stablity I have of late???

ADSL2 is often the best option out of ADSL, ADSL2 and ADSL2+., but you can only get it f you are on an ADSL2+ connection.

Many routers allow you to select it. A few ISPs understand enough to configure it at the exchange end, but most seem only to know setting it to ADSL2+ or ADSL .

ADSL Max is dead or dying anyway. You are probably now on IPSC, which is an interim stage.

ADSL2 uses the same frequencies as ADSL, with a better protocol. Generally a tiny downstream increase, (better than ADSL2+ in many cases), and useful upstream compared to ADSL. Stability comparable with ADSL, where on longish lines ADSL2+ can be less so.

I'm not sure how accurate the IDNet checker is. When my line was due for upgrade to ADSL2+ last year I tried several checkers to see if it had actually been upgraded. Whereas Zen and others showed that ADSL2+ was available on my line the IDNet checker showed only ADSL Max. I've just tried my number in the IDNet checker and it shows ADSLMax despite my having been on ADSL2+ for some months now. It might be worth using the Zen checker as well.

Thanks for that! I didn't know they didn't do a pukka live test. The idea is sound though, so I will stick with your suggestions the next time someone asks. I'm not sure the Zen one isn't just quoting the BT Wholesale checker though.

The Zen one isn't 100% accurate when it comes to where it states whether a line has been upgraded to 21CN. I popped my number in (My exchange has recently been upgraded - Should be switched over tomorrow) and it said I've been upgraded, however I'm still on the old Alcatel DSLAM (20CN).

It gives the same quote as the BT Wholesale expected speed (They both give 17Mbps for me).

I don't think that BTW report necessarily means that ADSL2+ is enabled. For exchanges that are scheduled for FTTC but not enabled, users get their FTTC estimates with exactly the same wording.

If you put your phone number into the IDNet checker on this page see which package page it takes you to.

Not the case with ADSL2+ - this is my exchange which is due on the same time:

Your exchange is planned to have ADSL2+ by 31st March 2012. Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 12Mbps; typically the line speed would range between 7Mbps and 17Mbps. Our test also indicates that your line could support an estimated ADSL 2+ Annex-M broadband upstream line speed of 1Mbps and downstream line speed of 12Mbps; typically the downstream speed would range between 7Mbps and 17Mbps.

Tried the Zen checker at it says 2.5Mbps and up to 20Mbps which AFAIK equates to ADSL2+

This seems to echo the BTW checker ???

FWIW my Speedtouch config says G.992.1 Annex A and remote vendor ID ALCB !

Edit ~ various online checkers all say the up to 20Mbps even PlusNet is on the list However I wonder if they are confusing the fact that there are two LLU providers now at the exchange but if so why is PlusNet listed as an up to 20Mbps ie ADSL2+ provider at my exchange???

As it seems the exchange may have been WBC enabled earlier than samknows knows, what's surprising about Plusnet being on which list?

Hi Routefinder,

ADSL2+ is available from us, and although your speeds probably won't increase dramatically you will now get 88.2% of the sync rate as your profile. Also, on your current 20CN connection, if your line drops a few times you can find that the BT IP profile goes down and can take a few days to come back up. Now, with 21CN, profiles are allocated immediately depending on your sync rate.
