DEVICE AND METHOD OF EXCHANGE TEST, AND RECORDING MEDIUM THEREOF

PROBLEM TO BE SOLVED: To efficiently conduct the test of call processing connection between an exchange and a PBX(private branch exchange), without using an actual PBX. SOLUTION: An HMI(human machine interface) part 32 receives control information from a maintenance terminal. A device control part 31 controls the operation of a PBX confronting test device, in accordance with the control information. An exchange I/F(interface) part 30 mutually informs state change information of an exchange with the PBX confronting test device. An event reception part 33 supplies an event notice to the device control part 31 via the exchange I/F part 30. The device control part 31 executes a processing corresponding to respective events at prescribed timing and shifts the device to a prescribed state, based on a state shift table 34 where the operation of the PBX confronting test device, which is required for realizing connection sequence between the exchange and PBX, is described and a timing table 35 where the reference value of timing among the events in connection sequence is set.
