I have a Cisco 1721 with WIC-1ADSL,
it used to connect to the Internet,
until the internet connection(100 hours) expired.
after that it can connect just only Layer 1.
ATM0 is up,line protocol is up.
ATM0.1 is up,line protocol is up.
but no ppp authentication(from debug ppp nego,ppp authen).
For helping from service provider,they used other
ADSL modem brand,and they can connect to the internet,
using internet account from Cisco 1721.
I have tried by using Cisco ADSL troubleshooting.
This is the configuration.
