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. It determines how the system
resources are allocated to the connecting endpoints.
The System Card Configuration Mode determines the resource allocation
method used by the RMX to allocate resources to the connecting
endpoints. The method in which the system allocates the resources is
defined in the Video/Voice Port Configuration. Two allocation methods are
available:
•
Flexible Resource Capacity™ – This is the default mode and the
only mode that should be selected in MCUs used for Audio only
conferencing. 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 all 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 160 video resources, but only one
MPM+ card is currently installed in the RMX, the system lets you
convert 160 video resources to Audio Only resources although only 80
video resources are available for conversion and 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
• The maximum number of PSTN participants is limited by the maximum
number of E1 or T1 PRI lines that can be connected to the RMX.
• RMX’s with 500MB of memory can support a maximum of 400 simultaneous
participant calls, regardless of how system resources are allocated. This
limitation applies to RMXs configured with either MPM or MPM+ cards.
RMXs 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 RMX 2000/4000 Administrator’s
Guide, "System Information” on page
