card types. G.719 audio algorithm is not supported with MPMx or MPMRx cards.
Card Configuration Mode Selection During Startup / Restart
When the MCU is started with Version 8.3 or later installed and no media cards, the RMX is set to MPMRx
Card Configuration Mode by default.
In following situations, the RealPresence Collaboration Server (RMX) 4000 can be switched between two
card configuration modes:
● The RMX switches between MPMx and MPMRx Card Configuration Modes when MPMx/MPMRx
cards are removed or swapped while the system is running.
● The switch between Card Configuration Modes occurs during the next restart.
Installing or swapping MPMx and MPMRx cards while the system is off will not cause a switch in the Card
Configuration Mode when the system is restarted – it will restart in the Card Configuration Mode that was
active previous to powering down.
