I have a 1760 with a 1 ADSL port, the carrier have a problem in the network and when carrier resolved the problem my internet connection is not restored, if I connect the carrier modem (2wire) the internet connection work, I changed the spliter, cable and wic, the status of the atm interface is line down and protocol down

When connect the modem provider, I note that the speed was increased to 4mb

This is the config:

interface ATM0/0
no ip address
no atm ilmi-keepalive
dsl operating-mode auto
pvc 8/35
  pppoe-client dial-pool-number 1

I enabled debug atm events and have a error

Have you tried hardcoding the 'dsl operating-mode' ?

You may need a firmware update. Unfortunately, the only legal source I know, it's Cisco TAC.

Open TAC case, ask for firmware 3.9.35

Note. you may need to get to escalation team before speaking to someone that knows what are you talking about.

If you do not have TAC access you may as well give up and get an 877 instead.
