MCU Card Configuration Mode Guidelines
MPMx and MPM+ Modes
• MPMx and MPM+ cards installed in the system cannot be used
simultaneously. Therefore, the RMX can operate in either MPM+ or
MPMx Card Configuration 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 both MPM+/MPMx cards.
• G.719 audio algorithm is not supported with MPMx.
Card Configuration Mode Selection During Startup /
Restart
When the MCU is started with Version 7.0.x installed and no media cards,
the RMX is set to MPMx Card Configuration Mode by default.
• The RMX switches between MPMx and MPM+ Card Configuration Modes
when MPM+/MPMx cards are removed or swapped while the system is
running.
• The switch between Card Configuration Modes occurs during the next
restart.
• Installing or swapping MPM+/MPMx 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.
