[nsp] IP QoS with FR/ATM?

[JJ]

I am trying to understand how ip qos works with FR and
ATM. 

I read that both FR and ATM do per vc queueing, is
this true?

If I configure CBWFQ udner one fr or atm pvc, does the
router have two sets of queues? one set for different
classes of ip packets, after the ip packet got
dequeued from the ip layer, they will be queued again
under that pvc? is it same for fr and atm? 

I can not find anything from cco, all of the qos docs
either explain ip qos or atm/fr qos.

thanks for any help.

JJ
