Oh, I thought I was clear enough? Sorry about that then.

C2620, 64M RAM. Running latest IP Plus, 12.3.18. 4 port ATM card.
What are the number of usable VC's for the ATM interface and the IDB limit
for the 2620? If it where a C2620 limit, would a 3640 running the same ATM
card resolve this?
Thanks again,
