Cisco Vip Cards.

Be careful. Cisco recognizes that VIP2-40's with OC3-PA's and any other PA 
co-habitating the VIP card will cause problems (packet loss under peak 
conditions). This is due to the huge overhead the SARing takes on the VIP's 
CPU. Cisco will not support multiple PA's within a VIP2-40. This is the 
primary reason they came out with the VIP2-50.

We have VIP2-40s running all over our network
with various port adapters (OC3, 8port serial etc)
and have had no problem besides flakiness when
we first implemented them.  Everything is working
well now.
