Hello,
One of our customers in The Netherlands has an ADSL line over POTS from Versatel (provider is IntroWeb). Because the Cisco 877 we sold to the customer wasn't available to us yet, we temporarily installed a Cisco SOHO97. This worked perfectly. A few days later we went on site again with the Cisco 877, copied the config from the Cisco SOHO97 into the Cisco 877. But... no linesync. A 'debug atm events' shows the following:

We also tried several IOS versions (from 12.3.8 to 12.4.4), no solution.
Below is the output from the Cisco SOHO97, which IS working on the DSL line from Versatel:

The odd thing is the empty 'Vendor ID' string under ATU-C(US). Configuration of the ATM-interface in the Cisco SOHO97 and Cisco 877 is identical:
interface ATM0 no ip address ip route-cache policy ip route-cache flow no atm auto-configuration no atm ilmi-keepalive no atm address-registration no atm ilmi-enable pvc 0/32 encapsulation aal5mux ppp dialer dialer pool-member 10 ! dsl operating-mode auto
We also tried every possible option for the 'dsl operating-mode' command, no effect.
Anyone seen this before, or know a solution?
