Below is a cut-n-paste from another Qwest OC-3 aggregation port.
We used a PA-A3-OC3SMI:
   !Slot 6: type ATM WAN OC3 SMI, 1 ports
   !Slot 6: hvers 2.0 rev A0
   !Slot 6: part 73-2427-04

I won't guarantee that it is the ideal solution -- but it worked for
several years.  The 'range' command is useful to keep your config
looking cleaner.  The 'pvc-in-range' command is useful for "one off"

Hope this helps...  (If it is useful, an engineer that worked for me
put things together.  If it isn't useful -- it's all my fault...)
