Re: Cisco 1801 no more ADSL sync

Looks like you will need to upgrade your ADSL firmware. Would be easy if you have a contract with Cisco.

Re: Cisco 1801 no more ADSL sync

Is the CD LED lit on your ATM interface?

Can you post the configs on the ATM interface, Dialer and DSL configurations?

You could do a loopback test on the ATM interface to check if your ATM interface is working properly.
