About the Built-In MCU
You can use your Avaya Room System XT Series to join a videoconference hosted on an external
MCU or you can host a meeting on the built-in MCU if available.
A Multipoint Control Unit (MCU) connects several endpoints to a single videoconference. It can
manage multiple separate conferences simultaneously. It manages the audio mixing and creates
the video layouts, adjusting the output to suit each endpoint's capabilities (transcoding). The term
MCU refers to any Avaya or third party MCU.
You can add a license to most XT Series models to activate the built-in MCU to host
videoconferences locally (see Deployment Guide for Avaya Room System XT Series):
• MCU4 can host videoconferences with up to four participants (one local, three remote), with
additional calls (up to eight) being placed in audio-only mode.
• MCU9 can host videoconferences with up to nine participants (one local, eight remote).
Important:
The Avaya XTE240 and Avaya XT4300 can host up to four video participants.
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.
