We too bought a 7613 with SUP720/3BXL and for the GEs we bought a 48 port 
WS-X6748-GE-TX along with a DFC - WS-F6700-DFC3BXL.  Adding in the DFC 
doubled the price per port for us.

I am curious if the Meircom test 7604 was using a DFC or not.  Somehow, 
based on their numbers, I believe they were using a DFC card since I don't 
believe they could reach the numbers stated without it.  And if they did 
reach those numbers w/o the DFC card, what the hell are we buying them for?

And if they were using a DFC card, then they are extremely negligent in not 
stating it in the report.
