Introduction 
This section is dedicated to the functional description of the MCU (Multi-point Control Unit) integrated in the System. The MCU, 
if not enabled by default, must be enabled by entering an enabling code supplied by the manufacturer. 
For an easier reading of this document, MCU stays for “multiconference session”
