ができる。Next, the operation of the pseudo call generation device having the above configuration will be explained. First, when the pseudo call generator 6 is activated, the central control unit (CC) 5 transmits information about the 70 telephone exchanges under test (EXCH) that have been input in advance to the test executor via the machine interface (mI) 4. The telephone circuits (positions) 2 in each pseudo telephone unit (SUB) 1a to 1c are controlled based on
Pseudo calls are generated to all subscriber circuits (Lc) aa to 8c of CH) 7 and all trunks including service trunks. Then, when each pseudo call occurs,
The central control unit (CC) S is always a pseudo telephone unit (SUB)
The service signal sent from the telephone exchange center under test (EXCM) 7 is monitored via the service signal detection circuit (SVD) 3 in 11 to 1c, and depending on the presence or absence of a service signal corresponding to the progress of a pseudo call, The normal operation of this pseudo call is determined. For example, when a pseudo call is generated to the local subscriber circuit (LC) 8m of the telephone exchange under test (EXCH) 7, first,
The central control unit (cc) 5 is a pseudo telephone device for calling (SUB).
) Controls the telephone circuit (placement) 2 in Ia and makes a call. And, a pseudo telephone device (SUB) for calling f a
The dial tone sent from the telephone exchange under test (KXCH) γ is monitored through the service signal detection circuit 3 in If the signal is detected, the central controller (CC) S determines that this pseudo call test has failed, and displays a detailed message depending on the test failure situation to the test executor via the man-machine interface (MMI) 4. . In addition, if a dial tone normally transmitted from the telephone exchange under test (EXCH) 7 is detected via the service signal detection circuit (SVT) 3 in the pseudo telephone device (SUB) Ib for calling, the central control A device (CC) 5 controls the telephone circuit (place) 2 in the pseudo telephone device (SUB) 1b for incoming calls in order to make a call to the pseudo telephone device (SUB) 1e for incoming calls. Telephone equipment (SUB) 1 Pseudo telephone equipment (SUB) for calling the dial number of subscriber circuit (LC) 13c corresponding to c
XCH) γ. and central control unit (cc)
5 is a pseudo telephone device for calling (strn). This time, the ring tone is monitored via the service signal detection circuit (S■) 3 of 1b, and the service signal detection circuit in the pseudo telephone device for receiving calls (SUB) 1a. (SVD)3 to monitor the ringing signal. In this case as well, a pseudo telephone device for calling (SI
JB) 1b and pseudo telephone device for incoming calls (SUB)
j c, if the expected service signal from the central control unit (CC) 5 a is not detected within a certain period of time, or if a service signal other than the expected service signal is detected. In this case, the pseudo call test with
MI)4 to the test performer. In addition, if the expected service signal is detected in the calling pseudo telephone device (SUB) ib and the receiving pseudo telephone device (SUB) 1 e, the central control bag! (CC) 5 controls the telephone circuit (equipment) 2 of the pseudo telephone device 1c for incoming calls, and can respond to the incoming call from the pseudo telephone device fif1b for calling.
