PPPoE on an 871 help

I am trying to set up an 871 router to connect to DSL over PPPoE. As far as I can tell, it is set up correctly, but it doesn't look like it is negotiating properly. I have attached the config as well as the output from the debug ppp negotiation.

Am I missing something in the cofiguration? I am not real familiar with DSL.

Re: PPPoE on an 871 help

I am not worried about NAT, I can add that once I get the DSL up and running. I configured both PAP and CHAP as I don't know which one Bell South uses, and the tech support person I spoke with couldn't tell me.
