I was just about to move to Be Unlimited when someone told me about 21CN (BT's ADSL2+ sort of offering).

Now is anyone aware of how soon this 24mb service will be available?

I was a touch concerned that:-
a) It may be soon (eg: this year)?
b) If you want to return to use 21CN from an LLU (eg: Be) you'd have to pay a £55 connection fee, and worse still be disconnected?

If it's years off and it's just a possible £55 fee and no disconnection period that's fine... But if it could be available this year and/or moving back to it from an LLU (eg: Be) would mean a disconnection period then I'd be worried!

Anyone know anything about this?

Thanks!

run an exchange search and it will give you BT's expected target date for rolling out 21CN

for instance, mine is Q4 2010 :eek:

All my local ones are 2010, but I've heard that some areas are infact well ahead of that and those dates therefore are not to be believed?

Anyone know about the move back from an LLU to a non-LLU ISP? Do you get charged? Do yuo even worse have to be disconnected for a period?
 
As long as the ISP uses the SMPF version of LLU which BE does then you can move back using a MAC as long as you are not moving to an MPF LLU ISP like Bulldog.

The question of charging is more complicated as currently if the IPS has to use the process known as 'Provide with MAC' there is a higher charge for that when compared to a normal IPStream migration and a lot of ISPs will charge you for that, but a few don't.

Also with regards to ADSL2+ and 21CN the two are related but different. 21CN will come first then ADSL2+ and I would tend to believe the dates on Samknows as the early trials for 21CN may be doing well but there is no sign of a significant shift in the planned rollout times.
 
21CN is BT's project to consolidate all of there backhaul networks into a modern IP network. The idea being that the majority of trafic that BT carry is now data so more efficent to build a data network and pass voice over ip, also saves them maintaining different networks.
 
21CN has been delayed, i dont know why as Fujitsu were expecting to be making the products for it by now, were told we wont be rolling 21CN stuff out til next year.
