Video connections on an MCU and MSE Media blades

How many video connections can I have on the Cisco TelePresence MCU Series and MSE media blades?

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 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.

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

Therefore, the 4210, for example, has 20 video ports and a further 20 audio-only ports. These can be used for H.323 or SIP connections; therefore you can connect up to 20 SIP video participants, and also 20 SIP audio-only participants for example.

The Status > Conferences page on your MCU shows how many video ports are currently in use across the whole unit, including those used by participants, content sources and streaming viewers. This information takes the format A(B)/C, this represents:

  • A — the current value of this statistic
  • B — the maximum achieved value of this statistic (since last reset)
  • C — the maximum allowable number for this statistic (this varies by MCU model)

Statistics for which there is no set maximum will be displayed as just A (B), where A and B have the meanings as described above.

This article applies to the following products:

  • Cisco TelePresence MCU 4200 / MSE 8420
  • Cisco TelePresence MCU 4500
  • Cisco TelePresence MSE 8510 blade
  • Cisco TelePresence ConferenceMe
