Update June 2009
Please see this blog for details on how to take part in the ADSL2+ trial. Please do not add a comment to this blog. Thanks.
Trial Update
Last month we posted that we were ready to begin customer trials of Higher Speed Broadband using 21CN.
So far 26 of our customers have volunteered, along with 29 staff members and we now have 49 live lines (the remaining 6 are currently in progress or waiting for the exchange to be enabled).
Our provisioning lead times remain on target, only one of the latest orders had a delay which we put down to the exchange only just being enabled, all the others were delivered on time.
The customers that are taking part in the trial are starting to provide feedback in our forums about their speeds and experiences here.
Our current plans for the trial are to try and add a few more customers between now and Tuesday. If you’d like to volunteer please add your name to this thread and we’ll add you to the trial. Just for logistical reasons we won’t be placing anyone else on to the trial over the Christmas and New Year period so we’ll hold back any requests made after Tuesday until the beginning of January.
We will shortly be sending an email to a small number of customers on some of the enabled exchanges to let them know that 21CN is available and asking them if they’d like to take part in the trial. This will of course be completely optional. We’d like to add between 50 and 100 customers from this email to the trial in January (split into 2 batches).
So long as our success criteria based around the number of faults, contacts from customers and order delivery dates are met we will start increasing the number of customers in each batch.
BRAS Distribution
We thought it may be interesting to post a breakdown of the speeds our customers see. The following graphs are based on the BRAS profiles set at the exchanges.
The first graph shows the general distribution of speeds for customers on Max (we’ve excluded customers on 21CN, LLU and fixed rate 512, 1Mbps and 2Mbps products from this graph).
The second graph shows the speeds of customers on 21CN.
While the third graph shows the speeds those customers on 21CN had on 20CN before they were upgraded (note: a couple of the 21CN customers were new provides rather than migrations so don’t have a before profile).
There are a few unknowns where either the customer hasn’t connected yet or we’ve never had a delta report through from BT, normally these will be sync’d at the full 8Mbps.
About a quarter of our 21CN lines have a BRAS profile of 8000kbps or higher, the fastest is currently 17000kbps with a sync rate of just over 20000kbps. The big gainers thus far as we’d expect are those that had over 6Mbps on ADSL with some noticeable increases for some of the longer lines under 1.5Mbps.

For a few days my 'upload' speed rose but then reverted to pre-trial speed.
The median post-21CN BRAS profile doesn't seem to be above about 8Mbits - is there a reason for this?
Hello,
Could I volunteer / request ADSL 2+ trials at all?
What details do you need to know?

Hi,
I would also like to volunteer for the ADSL2+ trials. However I'm unsure of the status of the LLU at my local exchange - O2 and BE offer 20Mbs via this exchange but the BT Wholsale status says: 21CN WBC status: RFS date set : 31/03/2009.
I'd appreciate being added to the trial as soon as it's available.
Kind regards,
Bradley.

Hi - please consider adding me to the trial. Thanks. K
I would like to be added to the trial as and when my exchange is converted.
According the BT Exchange status this is scheduled for end of February 2009.
I have just purchased a new Linksys ADSL2 Gateway to replace my aging D-Link DSL-G604T router but not installed it yet.
Please add me to the list of trial volunteers. Ealing exchange was scheduled to be upgraded in Nov 08, though the website doesn't actually say whether the upgrade is completed.
I have the hardware and the exchange, <200m from Bristol West.
It would be great to be added to the trial!
Please add me to the 21CN trial.
Plusnet have confirmed my exchange has been upgraded.
Kind Regards
Matt.
Just received an email stating my exchange has been upgraded.
Please add me to the 21CN trial.
Thanks,
Martyn
Please add me to the liust of volunteers. I am in the correct area according to your email. Only problem is my hardware is a BT1800HG supplied by yourselves.I cannot find if this is compatible or not.
Please add me to your list for the 21CN trial. I have checked that the Rickmansworth exchange is suitable. Hardware is a Netgear DG834GT and suitable.
Many thanks

Thanks
Dave
Hi,
My exchange - Chiswick W4 - has now been enabled as of 16/2/09 and I would like to volunteer for the ADSL2+ trial.
Do I need to submit a ticket? This used to be the case, but your advice now seems to be just to add my name and email here.
Interesting to see the graphs and in particular the before and after figures for trial participants. While we have had a shaky run on ADSLmax speeds during December and have had some adjustments undertaken by BTW at the exchange thanks to PN's advocacy on our behalf, we now seem to have a reasonably settled IP Bras at 6 - 6.5k and speeds often measuring around 5.5k using PN's Ookla, and around 5.0k using thinkbroadband.com's speed testing system.
Sitting at the upper end of the ADSLmax range would seem to indicate that we could see some significant benefits from 21C network changes at the exchange, though our history of bungled switchovers by BTW - the move to ADSLmax left us without broadband for 5 weeks! - don't give us total confidence, but nothing ventured, nothing gained and I'd like to be able to give clients some sense of what they might expect.
Fingers crossed.
Simon.
Interesting - I'm happy for you to check - reassured in fact, it's just that I do seem to be logged in...
Please add me to the trial - my exchange is enabled (Altrincham) and my modem is ready...
Thanks,

I have been switched over to ADSL2+ today.
On the previous conection up to 8Mb my average speed was around 4.5mbps download.
The new service is as expected a bit up and down but my line speed is showing 15mb.
I have done a couple of speed tests with the following results
1) mybroadbandspeed.co.uk = 5913kbps download and 605kbps upload
2) speedtest.net = 8.76mb/s download and 0.46mb/s upload
I will check again in a weeks time once the line has settled down.
