Hans,
I haven't had the chance to work with ATM but according to the Link 0
Framer info you're getting LOF on the receive (loss of frame delineation).
Combine that with the number of uncorrectable errors on your receive and
I'd say that the problem isn't necessarily your router. You might want to
do a bit more checking on the BPX.

Hello colleagues,
I have a problem with my ATM connection from my Cisco router to a Cisco BPX
ATM switch. When I look at the line on the switch, the line status is ok.
When I run the 'sh cont atm 1/0' command, I get the following output (maybe
anybody as an idea on where the error could be); I know this is going to be
a very long mail, but I can't help it:
