The short answer is that you don't. Sure, you can plug a fax modem into a phone line that supports DSL, but it is just using the dial-up capabilities of the line and not the DSL capabilities.

With DSL, you'd use a DSL modem (with or without an included router), not a dial-up modem.
You do not need a dial-up modem. However, you will need to either purchase or rent a DSL modem, which works differently from a dial-up modem, and is usually outside the computer.
