W/ Portmaster to Ether

	Portmaster                        
                Qty 2 T1       	$400
	Portmaster                        
                Qty 2 T1      	$400
	Carrier Access
                Qty 4 	    	$400 

	Total			$1200	



W/ T400P to Ether

	T400P
		Qty 1 (4 T1)	$800
	Carrier Access
		Qty 4		$400

	Total			$1200


1) And T400P is already coded for. But Maximum Cards per Chassis is a 
prob.

2) Portmaster could potentially support more ports per cost

	I.E. 256-512 simultaneous being routed through one machine after 
	translated to SIP, codec'd and shipped?. as opposed to 96-256
	calls on one machine via 4 port cards

3) good luck getting the firmware source

is the firmware source freely available, -- I've been asked by others.
