OC3 Router

I was hoping that someone could point me in the right direction. I'm looking for a cisco border router as a backup for our existing. We have a 7206VXR with NPE400. The only thing we have in the router is a OC3c POS card on one side and a multimode Gig-Ethernet on the other. We are not doing BGP with this router (upstream is annoucing for us). Is there a vendor who can tell us the minimum we need to do this for emergency situations, or someone on the list who can recommend a cisco solution that can meet these requirments?
