BT 21CN Roll out?
 

BT's target date for 21CN for my area is 4th quarter 2009 (so basically, 2010) according to http://www.samknows.com/broadband/search.php

Got my exchange code from http://www.dslzoneuk.net/distance.php

Anybody else getting 21CN earlier?

Explained and put into words better than me 21CN

Re: BT 21CN Roll out?
 

Thanks for the link was very informative.

Correct me if i'm wrong, but will this only affect customers with a BT line and not NTL customers or will NTL be coming out with a similar project of their own?

Re: BT 21CN Roll out?
 

You're correct, but it will give you an option if NTL don't play "catch-up".

Re: BT 21CN Roll out?
 

Yeah, its going to be interesting to see what NTL have up their sleeves as there in the process of consolidating their quadplay service, come on NTL show us your cards !!!

Whilst 40 odd miles down the road in Skewen, Q3 2011

Re: BT 21CN Roll out?
 

The site BT about 21CN is all very nice but a lot of it is written in abstracts and marketing speak.

What will it actually mean in practical terms for customers? Any distinct advantages or improvements in relation to services received?

Looking at this it seems that its partly a consolidation and long term cost saving exercise.

Re: BT 21CN Roll out?
 

I personally can't see any real advantage for the consumer. After all, it does not look like you can do anything with 21CN that you can't with the current network. I am not even sure if it will be faster as the "last mile" is apparently the major holdup on ADSL, so unless BT are going to replace this with Ethernet or Fibre, it won't change the maximum speed.

Re: BT 21CN Roll out?
 

Correct, good to see you took to the time to see pass the hype and research it. ADSL2+ is coming alongside 21cn, wether or not they are classing this as part of 21cn or just doing it at the same time for marketing reasons I dont know. But on the whole it looks like 21cn is something to reduce their costs and they have decided to market it as some magic upgrade, most people might be fooled into thinking the speed increases from adsl2+ are as a result of 21cn when it will have nothing to do with it.

As Stuart said as well for the people who dont have short lines the advantages will be very small if any, adsl2+ most of the speed benefits are lost on longer lines.

In addition things like this are worrying.

So 21cn will have qos and is needed since voice will go over VOIP backhaul, is this going to be a 1st stage in wholesale level traffic shaping and premium fees for unshaped traffic? only time will tell.

Re: BT 21CN Roll out?
 

From reading over some information about this before, I had been left with the impression that 21CN included installing ADSL equipment at street cabinet level, in order that more people can get high speed connections and effectively receive "next generation" services like BT Vision.

It would seem that's not the case and I guess its very unlikely to happen even in the next 5 years, when at the moment some exchanges have yet to be ADSL enabled.

Re: BT 21CN Roll out?
 

Jan-Mar 2009 it says for me.

Re: BT 21CN Roll out?
 

Partly right, although ADSL2+ and 21CN are completely separate programmes with very little cross-over.

BT cannot keep on using the same aging technology (System X is 20 years old!) so needs to modernise. Moving away from traditional voice-based technology to IP is a logical step as BT will then not need to have all the different 'high-level' networks (voice, data, packet switching, even telex!).

At the same time, there are literally thousands of BT exchanges arcross the country which need maintaining. Thanks to the changes in technology over the years, most of them are now at no more than 25% occupancy. So getting rid of the local exchange would save lots of money.

NTL and Telewest were quite fortunate that they could build from a clean sheet, and not have the burden of an aging fault-ridden legacy network.

As an aside, just over 25 years ago, there was a ripple of amazement in my office when a residential customer rang to order a modem from us - the very latest 300bit/sec one. Up to then, we'd only offered them to businesses.

you forgot the axe10 which they use in some places instead of System X.
