Is ADSL2+ still on trial at BT?

Is ADSL2+ still on BT  trial or is it  just PlusNet trialing it?
The reason I ask is several weeks after moving to ADSL2+ it still seems to be in some sort of experimenting mode. For a week or more I had a stable connection of 126147 with few errors and a SNR of 6/7. This morning I notice I had resyned over night at 152277 with loads of errors and a SNR of 5. On rebooting  I have again synced at 150432, with I suspect high errors.
Is there any feed back on customer experience being fed back to BT and is there any point customers reporting odd goings on?

Hi George,
For us it's a trial.  From BTs perspective it is still in the early days, but we are feeding back customer experience to them to allow them to look into the feedback that we are getting to see if there are any improvements that they are making.
There's certainly no harm in joining our trial if you would like to do so.

Please could BT invent SRA?

Some people invented SRA close to 10 years ago ... it will take a little while for BT to realise it is a good thing! Sad

Perhaps an on-line feedback/questionaire would be a good idea?
The results/reviews could be shown for all trialers and potential trialers to see. Probably a lot of work involved but is it a possibility?

That's certainly something that we could set up for our own customers.
Good idea Smiley

Re: Is ADSL2+ still on trial at BT?

you might want to go to court to get an order that bans me from leaving feedback tho jameseh Wink
at the moment my gain / lose of thoughput on adsl2 comapred to adsl stands at this moment at minus 504kbps
sure you all know that i would perfer my adsl equimpment at the exchange with max preminum for better upload sync than i have at this moment and my 500kbps downspeed back. plus nice and stable
line
bt's new equmpiment just dosent seem to suit long lines its not case of no improvment its case of it robbing speed of us that we had very little of before

Re: Is ADSL2+ still on trial at BT?

From what I can see the training never stops. I had a stable connection for weeks around 12 meg then it jumped to 14 Meg with loads of errors for a day or so. Then back to 12 Meg, again stable. Then to 15 Meg with loads of errors, now it's back to 12 Meg. I've had 29 re syncs so far and not one of them has been at the same speed twice.
What ever BT is using to run ADSL2+ seems very iffy and should not take weeks and umpteen re syncs to decide what I line can handle

Technically the training doesn't stop - but the timescales increase upto a maximum of (I think) 49 days.

What kind of communication system requires 49 days (and nights) to stabilize?
A very rubbish one?

Those two statements, to me, seem to contradict themselves.
But will things change when the trials are over bringing a more realistic training period ?

I believe it will be the same after the trial as the equipment in the exchances isnt actual on trial by BTw.
The trial is ony pn seeing how to work with the new 21cn centrals ect and how they are going to be able to manage the extra traffic that will be on the network, falut process, blah blah blah
Basically PN have no control over how BTw setup the msan's including the ever on going training period's if they did i am sure PN would make BTw use Seamless Rate Adaptation (SRA)

It's not as stupid and contradictory as it sounds.
You sit on a speed for 3 days.  If it stays stable, it'll try the next step up.  If that's not stable, it'll revert to the last stable speed.  If that is stable for 6 days it'll try again, and so on.
That's my understanding of it anyhow.

But it's not trying the next step up unless you call 12meg to 14 or 15 meg the next step up.  One jump was from around 12meg to 15meg then back to 12 meg again. I've kept a not of all my sync speeds and there is no pattern.
For instance I could reboot and get one speed, reboot again ten minutes later and get a faster or slower speed with the same SNR and ATT.
