摘要： A system for connection and disconnection in a multipoint conference system of a cascade configuration, wherein when a list of line numbers of the MCUs and terminals engaging in the conference is input from an input unit of an MCU, a call origination/disconnection table is prepared comprised of the line numbers. When the table is prepared, a call origination/disconnection administrative unit identifies the terminals under the MCU and the other adjoining MCUs, calls and establishes a connection through lines, and, when the connections are completed, circulates a call origination/disconnection table to the other connected MCUs. These MCUs in turn then calls their terminals and their adjoining MCUs and so on until the end MCUs. Further, use is made of a connection list in which connection flags and the order of connection are successively written and use is made of a conference configuration list indicating the actual connections of the MCUs. This enables all the television conference terminals to be automatically connected and disconnected from a single location and enables MCUs which have become unnecessary to be automatically recognized and disconnected.
