Well the PCI bus is limited to 600M in the VXR chassis?  So I'm assuming
the absolute best you're going to see if around 300Mbps in either
direction.  But last I knew the PA-GE had a bandwidth point rating of
400 points, so perhaps that's 200Mbps in both directions or 400Mbps in
any one?  However, I have doubts the NPE-400 would be able to keep up in
either case.
