ABSTRACT:
A device which enables two or more users of outside lines to converse on equal terms with each other. The connection method provides a distributed form of processing. The outside lines are connected to corresponding voice signal lines which intersect with two-party conference lines which serve as connectors for two voice signal lines, and multiple party conference lines which serve as connectors for three or more voice signal lines. Connection is possible at any intersection point. The device is also fitted with a conference line selection signal decoder to enable connection of a voice signal line with a specific conference line as specified by an incoming signal. Exclusion control lines are fitted to prevent the connection of more than two voice signal lines to the same two-party conference line. The voice signal lines are connected to a voice processor to enable the output of voice signals to an outside line.
