PA-POS for OC3-c can be pretty expensive - $3000 or so. If you don't mind the cell tax the PA-A1-OC3 are only $500 or so but I'm not sure if they ever made a VXR model of this card. The PA-A3-OC3 are about $1000. The difference between the PA-A1 and PA-A3, besides the possible VXR/non VXR bus issue, is that the PA-A1s have less ability to handle queueing on a per VC basis - not an issue at all if you're just looking for cheap cards. I did a little searching after writing the above ... looks like the PA-A1-OC3 is a non VXR 600 mbit bus only card, while the PA-A3-OC3 was built for the 600 mbit standard and gigabit VXR bus boxes.

What is the most cost effective equipment to use to connect two locations with an OC-3c circuit? I currently have 7206VXR routers at both ends, so would prefer slot cards for those if feasible.
Excuse my ignorance, but I can't get hold of any pre-sales support at Cisco because the worms are overloading their phone reps.
