[c-nsp] Newbie question on OC3 on 7206VXR

I am about to light up our first OC3 on a 7206VXR NPE400 running 12.2(29b).
It's an ATM circuit from Qwest and will have a lot of sub interfaces on it
for individual DSL accounts for customers of ours. I've been doing this for
years on DS3's, but have never done an OC3.

My current set up on one of the DS3's is pretty standard:

interface ATM1/0
 no ip address
 no ip redirects
 no ip unreachables
 no ip route-cache cef
 no ip mroute-cache
 atm scrambling cell-payload
 no atm ilmi-keepalive
interface ATM1/0.32 point-to-point
 pvc 1/32 
  ubr 1500
  encapsulation aal5mux ppp Virtual-Template1
interface ATM1/0.33 point-to-point
 pvc 1/33 
  ubr 1500
  encapsulation aal5mux ppp Virtual-Template1
.and so on....

The card I've been told will work for the OC3 is a PA-A3-OC3SMI. I'm just
curious if anyone has any tips or tricks for a similar setup. I'd really
love to avoid the "banging my head on the desk" stage in this setup...

Thanks very much for any advice you may have.
