> 1) How many OC3 (POS and ATM) interface we can use in VIP4-80 card?
You can fill a router with OC-3 POS/ATM cards in a VIP4-80 configuration,
however, backplane performance will be better with an RSP8 as it has 64MB
MEMD vs 2MB on RSP4. The other caveat is idb limits - you should get 1024
in 12.0S, so that limits how many PTP PVCs.
> 2) How many OC3 interface we can use in 7507 with RSP4?
I would limit this to 5 - one per PA Bay, unless you are doing a good deal
of intraVIP switching, or expect < 80-90 Mbps per PA.

Not that I know of. I have this configuration on a box with no performance
issues running line rate, average packets size, no acls, and dCEF/dNF
enabled.

This is the preferred combination.

All Cisco part numbers with = suffixes are spares.
