DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 shows an example of the configuration of an electronic exchange system. That is, the electronic exchange 10 has a terminal 1 such as a push-button telephone and a terminal control card unit 3 for directly controlling the office line and the leased line 2, and is usually composed of a plurality of terminal control cards 4 ,.

A terminal 1, a local line, and a dedicated line 2 are connected to the terminal control card 4, and output a control signal via a control path 9 to a central control unit 5 that controls the electronic exchange 10. , The control signal from the central controller 5
It has a function of receiving the signal via the network and transmitting a signal to the outside of the electronic exchange 10.

Further, the electronic exchange 10 has a PB (push button) receiver card 6, and the dialed digits of the PB signal sent from the push button telephone 1 or the central office line 2 are transferred from the terminal control card 4 to the communication path switching device. It is sent to the PB receiver card 6 through the communication path 8 connected by 7, converted into digital data numbers, and sent to the central control unit 5 via the control path 9.

FIG. 1 shows a diagram in which the automatic tester of the present invention is connected to such an electronic exchange 10. That is, the automatic tester 21 includes the tester main body 22 and the terminal control tester card 2
3 and a PB receiver tester card 24. The terminal control tester card 23 is equipped with a central processing unit (not shown) and is installed in place of the terminal control card 4 of the electronic exchange 10.

The terminal control tester card 23 has an external communication controller (not shown) and is connected to the tester main body 22 via a communication line 25. PB receiver tester card 2
4 is installed in place of the PB receiver card 6 of the electronic exchange 10. Also, PB receiver tester card 2
4 is connected to the tester main body 22 by a communication line 26.

The test of the electronic exchange 10 is performed by the tester main body 22.
The test procedure is sent to the terminal control tester card 23 and the dial number of the digital data is sent from the tester main body 22 to the PB receiver tester card 24.

Next, the operation in such a configuration will be described. For example, now, a console (not shown) in the tester main body 22 is used to instruct a transmission test. Then, the tester main body 22 outputs the originator and the execution procedure to the central control device 5 in the electronic exchange 10 via the communication line 25, the terminal control tester card 23 and the control path 9 and makes a connection for connection. The previously dialed digits are output as digital data to the PB receiver tester card 24 via the communication line 26.

Then, the PB receiver tester card 24
Outputs the dialed digit of the digital data to the central control unit 5 via the control path 9 as if it were the outgoing dialed digit received by the PB signal from the communication path 8.
As a result, the central controller 5 uses the speech path switching circuit 7 and the like to perform a transmission test for the terminal 1, the office line, and the leased line 2.

As described above, when a transmission test is conducted by simulating a terminal, a station line, and a leased line whose dialed digits are PB signals, the dialed dialed digits are PB from the terminal control tester card which is the source. Since it is not necessary to send the signal to the communication path of the electronic exchange, the terminal control tester card does not need the PB signal generator and the PB signal sending control device, and the terminal control tester card can be made compact and lightweight. .

[0022]

As described above in detail, according to the present invention,
A PB signal generator and a PB signal transmission controller are not required for the terminal control tester card, and an automatic tester for an electronic exchange can be provided which can reduce the size and weight of the terminal control tester card.
