Cisco 1721 ADSL Configuration for ATT DSL (No Internet Connection)


  I am asking for assistance in my configuration. Hoping someone could help me with my configuration. Currently I have a Cisco 1721 with a ADSL WIC trying to get it to work with ATT DSL. Currently, I  have ATT DSL -> Cisco 1721 (ADSL WIC) -> PC (crossover cable). Below is my configuration and all my interfaces shows UP but I am still unable to connect to the Internet. I think the problem is with my ATM0 is NOT pulling an IP address from ATT, but I am not sure how to correct this. Any assistance is greatly appreciated.
