No you can't I'm afraid.

Most consumer broadband is called ADSL and is "Asynchronous" and the 
modem at the customer's end has to talk to something called a DSLAM at 
your local telephone exchange. That's as far as the broadband modulated 
signal goes. It terminates at the DSLAM and is then IP over SDH or ATM 
from that point forward.

To be honest, if you shop around, I think you could find a capped 
broadband deal that would be cheaper than dial-up.

Most ISPs are phasing out dial-up all together so in a year or so you 
won't have much of a choice anyway.



PS - I'm assuming you are in the UK.
