MCU port matrix

The port provision of the various MCU models is shown in the table below. Each video port can be used by one video-conferencing participant. Each audio-only port can be used by one voice-only participant in a video conference. Where streaming and content ports are provided, when streaming and content ports are used up, video ports will not be allocated to streaming viewers or providers of content; where streaming and content ports are not provided, conferences with streaming viewers and conferences with content will use available video ports.

For the MCU 4500 and the MSE 8510 Media2 blade, the number and type of available media ports on the MCU is controlled by the port capacity mode which you configure on the Settings > Media ports page.

• HD+ mode supports high definition video participants at up to 1080p at 30fps
• HD mode supports high definition video participants at up to 720p at 30fps
• SD mode supports participants at up to w448p at 30fps

Port counts for clustered MSE Media2 blades

The maximum port counts for clusters comprising three MSE 8510 Media2 blades are as follows:

• For HD+ mode, the maximum number of port licenses that a three-blade cluster can utilize is 240. This will provide you with a total of 60 HD+ ports.
• For HD mode, the maximum number of port licenses that a three-blade cluster can utilize is 120. This will provide you with a total of 60 HD ports.

Note that in a cluster of MSE Media2 blades, SD ports are not available.

* Can be doubled using the MCU 6 to 12 HD port upgrade feature key

† Can be doubled using the 1080p capacity upgrade feature key

‡ Can be doubled using the MCU 6 to 12 HD port upgrade feature key. Can be quadrupled using both the MCU 6 to 12 HD port upgrade feature key and the 1080p capacity upgrade feature key
