1) The limits will vary widely from switch to switch and from one ATM-card
   to another.
2) Most systems will be limitted in the rate of SVC setups that they can 
   accept (usually, this is lower than the rate that NIC or router cards
   can generate).
3) Most NIC cards and switches also have limits on how many VCs they can
   handle.  For switches there are often both per-interface limits and
   switch aggregate limits.

I would hesitate to put specific numbers on any of these limits due to
the variations between vendors, and the variations (usually improvements)
from one release to another even within a vendor.
