MCUs with 500MB of memory can support a maximum of 400 simultaneous participant calls, regardless of how system resources are allocated.

MCUs 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.

Resource Usage in AVC CP Conferencing

Video resources usage varies according to the video resolution used by the endpoints. The higher the video resolution (quality), the greater the amount of video resources consumed by the MCU.

For information on resource usage vs. resolution, see Polycom RealPresence Collaboration Server 1500/1800/2000/4000 (depending on the machine) Hardware Guide.

AVC Conferencing - Voice

In Collaboration Server 1500/2000/4000 in MPMx Card Configuration Mode, one Audio Only resource is used to connect a single voice participant when CIF resources have been converted to Audio Only. However, if no CIF resources were converted, Audio Only endpoints use one CIF video resource per connection.

When video ports are fully used, the system cannot use free audio ports for video. When audio port resources are fully used, video ports can be used, using one video port to connect one voice participant.

In Collaboration Server 1500/1800/2000/4000 in MPMRx Card Configuration Mode, a voice port equals a CIF video port and there is no differentiation between voice and video ports.

Resource Capacity Modes

The installed media card type (MPMx or MPMRx) 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.
