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
MCU. 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 and applies to all Conferencing
Modes (SVC and AVC conferencing). 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 MCU. These resources are allocated as CIF resources
by default.
Example: If the MCU is licensed for 80 video resources, but only one MPM card is
currently installed in the MCU, 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 is applies to AVC conferencing only and the
resources cannot be used for SVC conferencing. It offers precise usage of resources,
allowing the administrator to set the number of resources guaranteed to each Audio

• MCU’s with 500MB of memory can support a maximum of 400 simultaneous participant calls,
regardless of how system resources are allocated.
MCU’s with 1000MB of memory are not subject to this limitation.
• MCU memory size is listed in the Administration > System Information properties box. For more
information see "System Information” on page 21-27.
From Version 8.1, only the MPMx Media Card and Card Configuration Mode are supported.
