The router said interface atm 0 is invalid.

As i am a newbie, i read the BBA configuration guide, and try some commands in this guide.

When i enter the "interface atm 0" command in global configure mode, it said "Invalid input detacted at '^' marker.

Hm, the router is 1941 without adsl wic, is that the problem? No adsl wic no atm interface?

Yes, that is correct. Do a "show diag" and it will tell you which modules you have installed (if any).

Thanks for your help.

I do think I should got a ADSL WIC, maybe EHWIC-VA-DSL-A is suitable.
