7200 Modules

What is the difference between the PA-MCX-2T/E1 card and the PA-VXB-2T/E1 card.

Can you connect your 7206 to a pbx with a PA-MCX-@T/E1 card for voice (PRI).

I have read cisco documentation and trying to find out why the VXB cost twice as much as the MCX

thanks

Re: 7200 Modules

PA-VXB-2TE1 is a adapter for voice which has special features which can be utilized for voice like compress, echo cancellatio and which has DSPs in built. PA-MC-8TE1 is a adapter used in WAN edges for High-Density ISDN Connectivity. You can find data sheets of both in the following links
