MPM+ and MPMx Media Cards

The RMX unit can work with either MPM+ or MPMx (but not with both simultaneously)
media cards. The card type installed in the system determines the Card Configuration Mode.
ISDN support is the same for all card types.
G.719 audio algorithm is not supported with MPMx.
Card Configuration Mode Selection During Startup / Restart
When the MCU is started with Version 7.x installed and no media cards, the RMX is set to
MPMx Card Configuration Mode by default.

RMX 4000 Component Description (Continued)
Description
The MPM+ cards, perform the various RTP, audio and video processing
functions on the RMX 4000 unit.
TI C6455 processors are at the core of each MPM+ card which are
available in the following assemblies:
•
MPM+20 (20 CIF resources)
•
MPM+40 (40 CIF resources)
•
MPM+80 (80 CIF resources)
Note: An MPM+ located (on the front panel) must face opposite (same slot
level) an RTM LAN card (installed on the rear panel). For more
information, see "RTM LAN" on page 1-27.
The MPMx cards, perform the various RTP, audio and video processing
functions on the RMX 4000 unit. TI processors are at the core of each
MPMx card which are available in the following assemblies:
•
MPMx -S
•
MPMx -D
Note: An MPMx located (on the front panel) must face opposite (same slot
level) an RTM LAN card (installed on the rear panel). For more
information, see "RTM LAN" on page 1-27.
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.
