No. You don't need a phone line for broadband technology other than ADSL. For
ADSL, you need a phone line but it doesn't have to be a BT phone line. ADSL
services can currently only be provided over standard telephone lines where the
exchange
has been ADSL enabled where you are not too far from the exchange and where the
line is of sufficient quality to support ADSL
broadband.
If you have cable television in your home / office it may be possible to receive
broadband via your cable operator. Alternatively broadband may be available
via satellite, a wireless network or other transmission media such as power lines.
