Abstract
PURPOSE:To facilitate change of a called subscriber and make direct telephone connection possible without a special device, by providing a called subscriber registering memory. CONSTITUTION:When the call of extension telephone set 1 is detected by channel control unit 6, central control unit 7 connects telephone set 1 and originating register trunk 4 and reads out called subscriber registered contents corresponding to telephone set 1 from memory unit 8 simultaneously. Read telephone number information of extension telephone set 2 is regarded as received by trunk 4 and is processed. Consequently, service between telephone sets 1 and 2 is possible through intraoffice trunk 9.
