There are PA-POS-OC3 cards (IIRC 3 flavors), and you need to shop for the
right kind to match up with the way your telco provider is handing the 
circuit to you (multimode, single-mode intermediate reach and single-mode 
long reach).

I recently needed some OC3 interfaces and went with older POSIP-OC3-50
cards (full size cards for the 7500 series) as they were much cheaper than
PA-POS cards.  They're basically specialized VIP2-50's with a double-wide
POS adaptor.
