resource per participant for HD resolution. Table 2-5 lists the resources
available to VSW conferences by line rate and card type.

may be lower when LPR and/or encryption are enabled.
The maximum supported video conference size is 160 participants.
Video Switching conferences require:
• All participants to have HD compliant endpoints.
• All participants to connect using the same conference line rate.
Video Switching conferencing mode is unavailable to ISDN participants.
Table 2-6 lists the recommended number of connections at HD1080p
resolution for fully configured and licenced RMX systems.
