I'm on DSL which goes through my phone company even though I don't have a land line at all. I don't pay extra for a line to have my computer on, they just set it up that way for computer use only. Maybe check into that if your internet is part of your phone setup or visa versa.
Some TelCo's do charge extra for DSL only service... I know the one I was with in NM was that way. DSL was $14.99/mo if there was phone service to the house. If not, they charged $19.99/mo AND if you decided to add phone service later, they charged an early termination fee and a reconnect fee unless you fought them on it (often took several phone calls to management level). TelCo's have always been legalized criminals.
