In order to achieve the above object, the automatic test apparatus for an all-electronic exchange subscriber board provided by the present invention comprises a terminal 23 for inputting and outputting a system, a processor board, and a memory board to process a signal input from the terminal. A controller 24, a function sensing device 25 for checking each function of the subscriber board by receiving the output of the controller, a relay board 21 for connecting a specific channel by receiving the output of the controller, and A transmission characteristic measuring device 22 connected to the relay board for measuring the transmission characteristic of the subscriber board, and a ring supply device 26 connected to the relay board to supply a ring signal.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic functional block diagram of an automatic test apparatus of an electronic switchboard subscriber board according to an embodiment of the present invention.

Referring to FIG. 2, an automatic test apparatus for an electronic switch subscriber board according to the present invention comprises a terminal 23 for inputting and outputting a system and a processor, and a processor board and a memory board to process a signal input from the terminal 23. The controller 24 to receive the output of the controller 24 and the function detecting device 25 to check each function of the subscriber board 27 and the output of the controller 24 to connect a specific channel. A relay signal 21 connected to the relay board 21, a transmission characteristic measuring device 22 for measuring a transmission characteristic of the subscriber board 27, and a relay signal connected to the relay board 21 It consists of the ring supply board 26 which supplies.

In the electronic tester subscriber board automatic test apparatus of the present invention configured as described above, the function test of the subscriber board 27 is performed according to the command input through the terminal 23, wherein the function of testing the function of the subscriber board is performed. The sensing device 25 has a subscriber's in / out detection function, a subscriber's call current detection function selected by the relay board 21, a polarity inversion detection function of the subscriber selected by the relay board 21, and the relay. It has the ring signal and ring trip detection function of the subscriber selected by the board 21.

In addition, the operation of the function detecting device 25 will be described as follows.

First, the in-relay test is connected to the desired channel by the relay board 21, the resistance of the 1.8K to the tip, the ring end of the subscriber board 27, and then the subscriber board 27 in the controller 24 While driving the in and out relays, read out the result displayed on the receiving end of the subscriber board 27 to determine whether there is an abnormality in the in and out relays. At this time, the current flowing through the communication path is sensed and the controller 24 reads the result to determine whether there is an abnormality in the communication current and polarity inversion.

In addition, the detection of the ring signal and the ring trip signal drives the ring relay of the subscriber board 27 in the controller 24 and then detects the tip signal of the subscriber, the ring signal appearing at the ring end, and the ring trip. Read to determine if there is a problem with the ring signal or ring trip.

In addition, when this functional test is completed, a transmission characteristic test is performed. This test confirms how much loss occurs while the analog signal supplied from the transmission characteristic measurement device 22 passes through the circuit of the subscriber board 27. In this test, it is detected using the transmission characteristic measuring device 22.

The automatic test apparatus of the electronic switchboard of the present invention as described above has to take a long time and requires a long time because all the items must be manually selected and then the results must be checked by sound or read by measuring the value of the instrument. Completion of the conventional disadvantage of not being able to test without the authorized person, the subscriber board can be tested automatically in the same environment as the system, so it is applied to actual production, which greatly contributes to productivity improvement, quality improvement and cost reduction.
