ATM interface won-t come up

Hi,

 

I have 2 Cisco 887's with identical problems. The ATM interface won't come up, even when tested on a known working line.

 

Running-conf for the atm is:

 

interface ATM0
 no ip address
 ip flow ingress
 no atm ilmi-keepalive
 pvc 0/38
  encapsulation aal5mux ppp dialer
  dialer pool-member 1
 !

sh ip int br
Interface                  IP-Address      OK? Method Status                Protocol
ATM0                       unassigned      YES NVRAM  down                  down
Dialer0                    unassigned      YES NVRAM  up                    up  

 

When enabling debugging I get the following every 5 minutes or so:

Can anyone shed any light on this?

 

Thanks

ok so you get dial tone on the line so that's working

your pvc looks correct for uk , what is your isp using pppoa ? can you post the dailer config

Are you using chap ? And its successfully authenticated have you debugged it ?
