AVC Conferencing - Video Switching Resource Capacity (1500/2000/4000 Only)

During a Video Switching conference, each endpoint uses one video (CIF) port.
The following table summarizes the resource capacities of fully configured MCUs with the various card types
per line rate in VSW Conferencing mode.

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

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. The table below
shows the number of video resources used for each resolution.
