Abstract

PURPOSE:To extend the capacity of exchanger without almost changing the fundamental building block and software, by separating the distribution switch circuit netwerk into outgoing and reception use and controlling the circuit network for outgoing with another processing system. CONSTITUTION:The distribution switch circuit network connected to the line concentration switch circuit network SCS is separated into the outgoing distribution switch circuit network ODSN and the incoming distribution switch circuit network TDSN, and the outgoing junctor SOJ for each module is connected to the circuit network ODSN and the incoming junctor STJ is to the circuit network TDSN. Further, the circuit network ODSN is provided with exclusive use of outgoing distribution switch circuit network exclusive processing system CP2, and the common line signal path CSL for communication is connected between the processing system CP1 of the basic system and CP2. As the share of functions, the processing system CP2 is in charge of the processing after the subscriber outgoing trunk SOT to the outgoing connection call, and others are in charge of the processing system CP1 including the management of interpretation data for other subscriber lines.
