As a student I had NTL broadband and didnt have a landline phone of any way, shape or form. They're talking utter balls and just trying to take your money when they say you need the landline, unless of course its part of a contract supplying both.
Yip got to agree i used to be the activation engineer for the midlands
that ment before the cable company got the the system into there hands i had to get it all up and running
the telephone line and the cable tv/broadband are seperate parts and cables of the network so you
dont need one to have the other
but i dont know the terms/cond so they might make you take both
