[c-nsp] PPPoA DSL up/up, no traffic

Hi,

I'm trying to configure a DSL line on a Cisco 1841 (C1841-IPBASE-M), Version 
12.4(1c).

The atm interface is plugged into a DSL line, it shows up/up, I have packets 
going out, but none coming back in.

Do I have to do something in particular to initiate the connection? Are 
there obvious errors with the config? Perhaps I need to contact the ISP.

Disclaimer: this is the first DSL line I've ever configured (might be 
obvious).

Thanks for the help.
Adam
