Aushman – should work regardless it would depend on the egress interface cards on the CAC.
Jafon – Same things apply with 3810 as the 53000.
The issue is with the CAC.
Junior – those are expensive, it may be good to get one that is intelligent enough to send it at the appropriate moment, i.e. pleiades or Adtran, but i guess it doesnt matter as long as it works.
