Re: 21CN

I have a question regarding 21CN

In short, will BT have to ensure xDSL to the house?

I live in an area where a lot of people have a line that is too long to
support DSL. I'm Ok (although it is rather slow, at least I have it) but
I know a number of people who cannot.

The way I had read the situation is that 21CN would only work if every
house (that wanted a phone) was DSL enabled. I have just been told that
21CN will start at the switch (normally trusted source).

However, my area is due for 21CN in 3rd quarter next year and already
the contractors (Enterprise) have been installing new poles and extra
(overhead) lines. It certainly looks as if they are upgrading the local
loop. Why would they do that if 21CN only worked inwards from the
switch?

What does the panel think, please? Is there any hope for my friends?

You'll see that copper still figures in the arrangement


Thanks for that link. Yes, copper does still figure. However DSL is
carried over copper today. While it would be nice to have end to end
fibre, I am more concerned about my neighbours being able to get
broadband.

As helpful as that web site is, it still seems slightly ambiguous. For
instance, there is the statement: "As an end-to-end Internet Protocol
(IP)-based network, 21CN will consolidate BT?s 17 separate network
platforms into one." To me, an end to end IP network is one that goes all
the way to the customer; not one that stops at the switch. Have I misread
this, please? Am I perhaps grasping at straws?


In a way yes. Unless, and until, BT deploy fibre to the customers premises
then the last leg of the network will remain analogue over copper.

On a more general point BT appear to be seriously behind in meeting almost
all their targets for 21CN
