RMX memory size is listed in the Administration > System Information properties
box.
In HD Video Switching conferences, an RMX with four MPM+ cards can
support up to 160 participants at HD1080p resolution at bandwidths of up
to 4Mbps and 80 participants at HD1080p resolution at bandwidths of up
to 6 Mbps.

MPMx and MPM+ Modes

• MPMx and MPM+ cards installed in the system cannot be used
simultaneously. Therefore, the RMX can operate in either an MPM+
or MPMx mode.
• MPMx Mode is the mode in which the RMX operates to fully utilize
the increased power and capacity of MPMx cards.
• ISDN support is the same as for MPM+/MPMx cards.
• G.719 audio algorithm is not supported with MPMx.

Operating Mode Selection During Startup / Restart

When started with Version 7.0 installed, the RMX enters MPMx Mode by
default when no media cards are installed.
