consumer ADSL is normally 50:1 - but that is just based on how the ISP
chooses to build their overlay with BT, and whether they use IP or ATM BT
services, or roll their own with LLU.
50:1 is actually worst - most ISPs over provision in practice, since
upgrading the backhaul can take a while.
BT business ADSL was always set to 20:1, and several of the business
alternatives choose to build for 10:1 or less - you can even get 1:1 if you
want to pay leased line style pricing.....
20:1 is documented somewhere - although i have never seen data rates as low
as that implies.
there is a good techie web site for cable:
http://www.chetnet.co.uk/
this seems to be run by insiders - and is full of useful info if you want to
know more about cable.

Agreed - but the old T&Cs let them decide what to think of as "abuse" so
they always had a cop out clause.
there have been stories of NTL customer getting "cease and behave" letters
for several months.
given 1 Gbyte is around 5 hours at 512k, and the cap is per day. The cap
does get worse as they up the line speed, since they dont vary the limit.
Anyhow - if i had a 2 or 3 Mbps access, i dont think my Netgear firewall (or
the set top box) could keep up....

cable isnt the same as ADSL, where the bottleneck is often the ADSL line, or
the way it is set up.
User line speed isnt fixed in cable - you share a half duplex, high speed
cable channel with a bunch of other local users (overall speed in 10s of
Mbps). Basically you are using something like a hub based ethernet.
cable speed is then limited per user by capping the data rate inside the
cable network to a fairly small fraction of the channel speed.
downstream bandwidth "costs" fewer resources on the shared cable, so cable
users usually get lower speed uplink capacity than on equivalent ADSL
services.
