Friend bought his first computer. What router does he need for AT&T DSL?

Dennis, there's an important piece of information missing. Specifically, what flavor of AT&T DSL? Is it U-Verse or the old aDSL?

U-Verse comes with a router/gateway so no need to buy one.

I don't know. It's probably an old basic AT&T phone line he has.
