The CT3 card is a complete waste. Why would I want to spend twice the
money and tie up a PM-4 slot for a M13 mux? If the CT3 card actually
terminated DS0 & DS1's directly on the card it would be a nice product but
to have to re-terminate the connections over to qudaT1 cards it is a
waste. I have a WideBank 28 (www.carrieraccess.com) which runs about $5k
and is a GREAT M13 mux. It is 1U high, NEBS compliant (for a bit more $$)
and doesn't eat a PM-4 slot

This would be sweet!

One could only hope. 'course they need the higher density first....
