multipoint control unit (MCU)
A multiport device, by means of which two or more audiovisual terminals may intercommunicate in a conference call. Note: A "principal MCU" has been assigned a superior controlling function in a call where two or more MCUs in that call are termed "satellite MCUs". The physical realization of an MCU may be such that two or more independent conferences may be set up within the same unit; logically, however, there is no relationship between these conferences; the text of this definition refers to an MCU only as a logical entity pertinent to the particular call of concern. [T1.800.06-1995]
