Anybody done/doing this with Cisco/StrataCom BPX/etc?  One of our 
providers attempted this with us about a year ago, without success.
This was before CEF/CAR, and they wanted to perform rate limiting/
shaping on our T3 down to 10Mbit/Sec.  The idea was to use frame-to-ATM 
translation (terminology?) and then ATM QoS tweaks in the BPX, 
before shipping it to a 7513 via HSSI.  

Cisco wasn't able to make the specific FR card involved work 
then, however.  I don't remember the switch card P/N.

Is CAR inexpensive enough processor-wise that this and the CT-3 
card make the above obsolete/moot?
