ADSL Connection dropping regularly

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.
