Exchanging system

Abstract

Abstract PURPOSE:To execute the connection in the sequence of an arrival even when plural calls come in to one subscriber simultaneously by storing the incoming sequency to the calling for a called terminal, calling a calling terminal in accordance with the stored incoming sequence and executing the call setting when a resource in the called terminal or the exchanging network is busy. CONSTITUTION:A subscriber 20 is the subscriber to subscribe to an incoming sequence deciding service, and subscribers 30 and 31 are the subscribers to execute the connection to the subscriber 20. Not only the subscriber to subscribe to the incoming sequence deciding service can usually receive the call by a subscriber No. of 'ABC-DFEG' but also the subscriber can receive the call even by the subscriber No. of 'IXY-ABC-DEFG.' The subscriber can register the starting time of the service. An exchanging device 10 has a processor 101 and an incoming registering memory 102 to store the incoming sequence, and when the subscriber 20 is busy, the exchanging device 10 registers the connecting request to the incoming registering memory 102 by the processor 101. The processor 101 calls the subscriber 20 and the transmitting terminal in the sequence of the registering of the incoming registering memory 102 and executes the call setting each time the subscriber 20 comes to be idle.
