•
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 19-78.

Resource Capacity Modes

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.
In Fixed Resource Capacity mode, the maximum number of resources is
based on the system license and the hardware configuration of the
RMX. By default, these resources are allocated as HD720p30
resources, the first time Fixed Resource Capacity mode is activated.
