Dell Latitude D600 DSL/NETWORK Help!

Hello. NEWB/FIRST POST. Please forgive if i'm posting this in the wrong section.

 

I have a Dell Latitude D600. I'm aware of wireless internet, but i'm not ready for that yet. I have DSL at home and I want tp hook my Laptop up to that. When I plug the DSL cable into the laptop nothing happens, I can't connect or anything. The laptop won't recognize the cable. I can connect with dial-up via phone line, but that is slow as heck. Please Help.

-Thanks To All in Advance!
