How else can BT know where to vector the actual ATM conversation?

I would have expected that, with one end in my local exchange, the other
end on the ISP's router, BT would use their management software to set
up a VC between those points over their ATM network, and that would be
it as far as their involvement was concerned. However, giggling for "BT
Radius Server" appears to indicate that it doesn't work like that;
perhaps the simple approach doesn't scale.

It doesn't actually know who your ISP is until your router tries to login.
If you reconfigure your router with the login details for another person
using a different ISP (but also on BT wholesale), you will find you can
login to their ISP on your line just like you normally log in to yours.
