[c-nsp] Is this throughput on ATM DS3 in 3640 normal?

[Peter Olsson]

Forgive me for answering myself. I meant atm clock internal below,
not clock source internal.

This is the ATM configuration in the routers:
interface ATM1/0
  ip address 172.22.48.2 255.255.255.252
  ip ospf network point-to-point
  no atm ilmi-keepalive
  pvc 1/42
   protocol ip 172.22.48.1 broadcast
