• RMX’s with 500MB of memory can support a maximum of 400 simultaneous participant calls,
regardless of how system resources are allocated.
RMX’s with 1000MB of memory are not subject to this limitation.
• RMX memory size is listed in the Administration > System Information properties box. For more
information see "System Information” on page 20-23.
The installed media card type (MPM, MPM+ or MPMx) determines the Card Configuration
Mode, which in turn determines the resource allocation method that can be selected for the
RMX. The resource allocation method determines how the system resources are allocated to
the connecting endpoints and it is defined in the Video/Voice Port Configuration. Two
allocation methods are available:
• Flexible Resource Capacity – This is the default allocation mode that is used in all
versions and can be used in all Card Configuration Modes. The resources are only set to
audio and video as a pool and the system allocates the resources according to the
connecting endpoints. This mode offers flexibility in resource allocation and is available
in MPM, MPM+ and MPMx Card Configuration Modes.
In Flexible Resource Capacity mode, in MPM, MPM+ and MPMx Card Configuration
Modes, the maximum number of resources is based on the system license, regardless of
the hardware configuration of the RMX. These resources are allocated as CIF resources
by default.
Example: If the RMX is licensed for 80 video resources, but only one MPM card is
currently installed in the RMX, the system lets you allocate 80 ports although only 40
video resources are available for participant connection. (However, an active alarm will
be added to the Active Alarms list indicating a resource deficiency).
• Fixed Resource Capacity – This mode offers precise usage of resources, allowing the
administrator to set the number of resources guaranteed to each Audio Only and video
connection type in advance. This mode is available only in MPM+ and MPMx Card
Configuration Modes.
