Understanding the MCU and Built-in MCU The endpoint needs to use the MCU or built-in MCU to initiate a multipoint conference. If the endpoint uses the built-in MCU to initiate a conference, no external MCU is required.
MCU As an indispensable component in a multipoint conference, the MCU is responsible for multiple functions, such as site access, video exchange, audio mixing, data processing, and signaling interaction.
Built-in MCU An endpoint with the built-in MCU function can initiate a multipoint conference by implementing functions such as site access, video exchange, audio mixing, data processing, and signaling interaction. The endpoint can work independently, without involving the other components on the videoconferencing network in conference scheduling. In this case, the endpoint functions as a mini MCU.
