ABSTRACT:
An ATM switching system1is provided with an ATM switch11,a reserved connection memory12for storing reserved connection information, a call history memory13for maintaining call histories of requests for connection from subscriber's terminal units2−1to2−n, and a call-signal processing section15.The call-signal processing section15generates a request for connection with respect to a trunk ATM switching network3by the use of the call histories in the call history memory13in the case where no call was issued from the subscriber's terminal units, and stores response results thereof in the reserved connection memory16.Thereafter, when there was a call from the subscriber's terminal units2−1to2−n, and contents of the request for connection thereof are the same as the reserved connection information, which has been stored in the reserved connection memory16,processing for connection is executed by the use of the reserved connection information. As a result, an ATM switching system by which response becomes possible in even the case where a large amount of calls are issued at the same time, besides reduction in cost can also be attained is provided.
