About the Built-In MCU
You can use your Avaya Scopia
An MCU, or Multipoint Control Unit, 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.
Avaya IP Office connects to the XT Series as a SIP server, allowing it to host videoconferences and add
Avaya endpoints to videoconferences.
Important:
If you do not register to IP Office, you cannot host videoconferences on the built-in MCU.
Your XT Series can host videoconferences on its built-in MCU, with up to nine (one local, eight remote)
participants. If you do not register to IP Office, you cannot host videoconferences on the built-in MCU.
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.
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.
