BT line upgrade

My exchange (reading south - http://www.samknows.com/broadband/exchange/THS)
is set to upgrade to 21CN WBC at the end of march. Does this mean that
at the end of march my broadband speed will increase? Will i be likely
to be charged more to get this higher speed broadband? At the moment i
am on 8meg, but get about 1meg, which i am guessing is to do with
distance, so would i be right in thinking i could expect 3meg (since
21CN WBC would be 24meg).

I am on BT, since they are doing the work will be likely to be one of
the early adopters?. Would they have two speed limits (8 and 24) or
just have the one? Obviously i don't really expect anyone to know
this, but i was just wondering.

No. 8M [or 8128kbps] is an arbitrary limit picked by BT, not imposed by the
technology in use. You might like to look at your line stats, these will
tell you if the 1M you're getting is due to your distance from the exchange
or not.

My down line attenuation is 53, so does that mean even with a 24meg
line the speed would still be about 1meg. I really envy all those
people that apparently get as high as 85% of their maximum.

This is my line information from homehub:

The 2 speeds are on different standards. An 8 Mbps router won't handle 24Mbps
(ADSL2+) so a hardware upgrade is almost certainly going to be required too
unless you accidentally already have an ADSL2+ one (pretty unlikely).

You certainly won't get an automatic increase either. Expect to pay to have
the line rejumpered and pay a higher monthly rate.

24Mbps sync and 22Mbps data IIRC is the max.
Don't forget that line length (above about 3.5km) may mean you get little
improvement.

Yes.

I sync at up to 8128 kbps now but with ADSL2+ the estimate I had from Be was
about 14-16 Mbps.

You sure about that ?

This explains it. It depends which standard you're on. BT are presumably not
supplying ADSL2, so '8 meg' is indeed the max.

It's not that unlikely that he has ADSL2+ capable kit, it's been around
for a couple of years now so there's a lot of people who have it without
even realising.

A quick search on Google indicates that the last three routers I have
bought for myself are ADSL2+ capable and all the routers I have bought
for other people over the last 18 months (at least) are as well.

Looking at that graph it seems i should be getting more like 3.5-4 mb
(looking at 53dB). When i signed up it said that i should be able to
get about 3mb (on the bt website) and on the samknows map (http://
www.samknows.com/broadband/mapping/mapping.php) it also lists it at
about 3.5:

ADSL available at ~3.5Mbps
BT Total broadband
TalkTalk LLU (8M is free)
Sky LLU (2M is free, 8M is £5pm)
AOL LLU (£10pm discount)
Pipex broadband
Plusnet broadband
Tiscali broadband
Tiscali TV
And many more...

ADSL2+ available at ~3.5Mbps
Be Unlimited
O2 broadband
UK Online (incl 20M packages)
Sky Max (LLU) (16M for £10pcm)

What could be making it so much less than what these say? Is it just
he line attenuation?
