Abstract

PURPOSE:To quickly and accurately analyze the defective part of a telephone exchange station by progressing a pseudo call while a service signal sent from the telephone exchange station is being confirmed at the test of pseudo call so as to decide the result of operating test of the telephone exchange station. CONSTITUTION:In starting a pseudo call generating device 6, a central control equipment CC 5 controls a telephone set circuit TEL 2 in pseudo call telephone sets SUB1a-1c based on the station information of a telephone exchange station EXCH7 to be tested given from a test execution personnel in advance to generate a pseudo call to all trunks including service trunks and all subscriber circuits LC8a-8c in the telephone exchange station EXCH7 to be tested sequentially. Upon the generation of each pseudo call, the CC 5 always supervises a service signal sent from the EXCH 7 via a service signal detection circuit SVD 3 in the SUB 1a-1c. The normality of the pseudo call is decided depending on the presence of the service signal corresponding to the progress of the pseudo call. The CC 5 supervises a call tone via the service signal detection circuit SVD 3 of the SUB 1b and also supervises a call signal via a service signal detection circuit SVD 3 in an incoming pseudo telephone set SUB 1c.

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
