Hi all,
I have recently switched out my Cisco 678 here for a Cisco 877 and am trying to get it working on my ADSL link. I have configured the 877 with the PPPoA username and password and static IP, but the PPP light never comes on. (CD light is solid on and DSL line is trained)
The tech at the ISP told me that my router is constantly logging on (successfully, he states) but I never get a PPP light and the link never comes up.
The modem is running Advanced IP Services IOS 12.4(15)T1 and DSL FW 3.0.14.
Here is the sanitized config:

Does anyone know what could be causing this?

I did some more research and debugging and it looks like my authentication is failing, but I am assured by the ISP that I am using the correct username and password. In fact, when I plug the 678 in using that User/pass combo, I get a good negotiation and the circuit comes all the way up.
Here is the debug output:

It appears that when I send my username, the device on the other side prompts me "Username: ", suggesting that I have given an incorrect logon name.
Has anyone seen this before? I am trying to get details about the device on the other side of the link, but it's difficult to get ISP techs to tell me exactly what hardware they have.
Any help anyone can offer would be great.
I've already tried switching between dsl operating-mode auto and ansi-dmt with no change. I also have removed the CHAP authentication from the Dialer0 interface since I verified that the ISP was using PAP.
Thanks,
Chris

Looks ok to me, the only difference I have is:
dsl operating-mode auto
cdp enable
pvc 0/38
Here:
!
interface ATM0
no ip address
no ip unreachables
no ip mroute-cache
atm vc-per-vp 64
no atm ilmi-keepalive
dsl operating-mode auto
cdp enable
pvc 0/38
encapsulation aal5mux ppp dialer
dialer pool-member 1
