About the Built-In MCU

You can use your Avaya Scopia
or you can host a meeting on the built-in MCU if available.
An MCU, or Multipoint Control Unit (Equinox Media Server), connects several endpoints to a single
videoconference. It manages the audio mixing and creates the video layouts, adjusting the output to
suit each endpoint's capabilities.
You can add a license to most XT Series models to activate the built-in MCU to host
videoconferences locally (see
• MCU4 can host videoconferences with up to four participants (one local, three remote).
• MCU9 can host videoconferences with up to nine participants (one local, eight remote).
Important:

The embedded MCU can mix standard definition and HD endpoints in the same meeting, without
one impacting on the other. The built-in MCU also supports both wide-screen (16:9) and standard
formats (4:3), incorporating them seamlessly into the video layout. In order to conserve bandwidth,
you can limit the number of participants that the embedded MCU can host.
While generating the video layout, the built-in MCU must shrink each participant's image to fit the
layout. So while the composite video layout remains in HD, each participant's image within the
layout can reach a maximum resolution of 448p.
When using the XT Series as an MCU only, not participating locally, we recommend blocking the
audio and video input from this XT Series during the meeting. You can do this by enabling privacy
settings. You can block the audio and video input completely or you can ensure that only users with
a PIN can access the audio and video.
For the best experience when using the XT Series MCU Edition, we recommend activating the
license known as Maximum bandwidth extension (12Mbps total for all participants) to avoid sending
video at the default lower 6Mbps total for all participants (see
Optional Features on page 93).
