hi Guys
Ive got a 1721 configured at home on the end of my ADSL line.
I think Ive got it configured ok, but for some reason it drops the DSL connection at least once every hour.
Its doing my head in! Ive tried everything i can think of, but still it drops.
Could it be a faulty WIC?
Heres my config:

Kindly do a bebug of the ATM interface
Disconnecting the 'ring' wire in the phone socket may help sometime. It can be result from some important misconfiguration in your own network.
