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.
