MPM/MPM+ and MPMx Configuration Modes
The RMX unit can work with either MPM or MPM+/MPMx (but not with
both simultaneously) media cards. The card Type installed in the system
determines the Card Configuration Mode. When MPM card is installed in
the MCU, it operates in an MPM Mode. If MPM+ cards are installed, the
RMX operates in MPM+ Mode giving the administrator control and
monitoring of resource allocation and usage within the system. When
MPMx cards are installed, the RMX operates in MPMx Mode giving the
administrator enhanced control and monitoring of resource allocation and
usage within the system.
MPM+ cards are supported only with D-type chassis and software
version 4.0.
MPMx cards are supported only with D-type chassis and software version
7.0.
Table 2 summarizes the resource capacities of the various video resource
types in an RMX containing two MPM and MPM+ cards.
