Dsl Without Phone Line How Does Dsl Without A Phone Line Work?

How does dsl without a phone line work? - dsl without phone line

I have ATT DSL service with a phone line and do not use it as a phone, because I wanted to get rid of and reduce the cost of the Internet. But I do not get rid if it means I have to buy lots of expensive equipment and pay for all sorts of other things like wireless is no longer necessary. Any information would be appreciated.
