PURPOSE:To automatically generate various artificial call processing sequences, by determining the event that shall determine the next operation from plural events by the combination of the timing of the timer in compliance with the respective events. CONSTITUTION:In a central control unit 110 to control a network 100 of a switchboard and perform the switching connection 101 is built in, and in compliance with plural operations that can be performed next from a certain state plural service timers 102 to determine the timing to start each operation are installed. In case it is changed from the state A in the switchboard interior to the state B or C, 2 times t1 and t2 are set to arbitrary values at state A, and when the timer t1 is previously made with time out, the timer t2 is stopped, as well changed to the state as a pattern (a), and when the timer t1 is previously made with time out, the timer t1 is stopped, as well comes to be changed to the state C like a pattern (b), and by changing the state transition, various artificial call sequences are generated against the switchboard. The call control in this case is performed by the state transition of memory block for call control 103 by each timing. |
