for any resolution (including HD). The table below lists the resources available to VSW conferences 

by line rate and card type.

Capacity numbers are for maximum capacity card assemblies. These numbers may be lower when LPR and/or 

encryption are enabled.

The following table lists the recommended number of connections at HD1080p resolution for fully 

configured and licenced RealPresence Collaboration Server (RMX) systems with MPMx cards. For
