Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a communication path control circuit testing method for an electronic switching system using an M-product program control method, and particularly to a method for testing a communication path control circuit of an electronic switching system using an M-product program control method, and in particular, a test method for testing a communication path control circuit in an electronic switching system using an M-product program control method. This paper relates to a communication path control circuit test method carried out in .

BACKGROUND OF THE INVENTION Conventionally, the normality test of this type of communication path control circuit has been carried out by testing the communication path control circuit and its higher-level equipment based on the operation from the subscriber actually connected to the electronic switching system and the signals transmitted from the subscriber circuit. A normal operation test was being conducted with a certain communication path device.

Problems to be Solved by the Invention In the normality test of the conventional communication path control circuit described above, the actual [[] It was necessary to generate a call J, and in this case it was necessary to prepare a telephone set to connect to the subscriber circuit corresponding to the speech path control circuit to be tested.

In other words, in order to test between the call path control circuit and the call path control unit, a telephone must be connected corresponding to the call path control circuit, and the normality test of all the call path control circuits in the electronic switching system must be performed. It was a very troublesome thing to do.

In addition, since it is necessary to generate a "call" to discover a fault in the communication path control circuit, after the operation is started, a subscriber connected to any communication path control circuit will not be able to "attempt to connect call J." In some cases, failures in the communication path control circuits were discovered at the same time, resulting in an unavoidable decline in service.

The present invention has been made in view of the above-mentioned conventional situation,
Accordingly, an object of the present invention is to provide a new communication path control circuit normal operation test method that makes it possible to solve the above-mentioned problems inherent in the conventional technology.

Means for Solving the Problems In order to achieve the above object, the communication path control circuit normal operation test method according to the present invention includes a test execution control section, a test execution management section, a test judgment control section, and a maintenance control section. Test execution control can be performed on the communication path control circuit according to instructions from the test execution management section and test execution information predefined in the test execution management section.

The test determination control section also has a function of creating test result information transmitted from the communication path control circuit and notifying the maintenance personnel.

In this way, it is possible to perform an iE constant state test between the channel control circuit and the channel equipment without actually using a subscriber connected to the electronic switching system.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a speech path control circuit normal operation testing device according to the present invention.

In FIG. 1, information necessary for the normal operation test of the communication path control circuit input from the maintenance control unit M30 is input to the central processing unit 1.
The data is stored in the storage section of the test execution management section 13 via the maintenance control section 14 of No. 0. Further, when the test execution start command inputted from the maintenance control device 30 is transmitted to the test execution management unit 13 via the maintenance control unit 14, the test execution management unit 13 sends the test execution control unit 12 to the communication path control circuit normal operation test. Communicate necessary information and test execution instructions. The test execution control unit 12 that received the test execution command controls the communication path control circuit 2 of the communication path system bag W20.
2 to transmit instructions in a predetermined format. Further, information from the communication path control circuit 22 that received the test execution command is transmitted to the test determination control section 11.

The communication path control circuit 22 analyzes the command and stores the information contained in the command in its own memory.If the command is an instruction to start a test, the communication path control circuit 22 stores the information in its memory. Information regarding a call such as calling, sending digits, disconnecting, etc. is transmitted from the subscriber circuit.
Similarly to "call", the communication path device 23 passes through the communication path control circuit 22.
transmitted to. Whether the information transmitted to the communication path control circuit 22 at this time was transmitted via the test execution control section 12;
It is not possible to identify whether the call is transmitted from the subscriber circuit 21 or not; in other words, the operation of the higher-level equipment after the communication path control circuit 22 is completely equivalent to a "call" from a subscriber connected to the electronic switching system. It is possible to test the normality of the signal information of "r call" between the communication path device 23 and the communication path device 23. This is a feature of the present invention.

Further, the test determination control section 11 monitors the communication path control circuit 22 that receives a test execution command from the test execution control section 12, and transmits test determination information from the communication path control circuit 22 in a predetermined format. Based on the transmitted information and the information from the communication path control circuit 22, test result information is created to be transmitted to the maintenance personnel. The test judgment control section 11 transmits this information to the maintenance control section 14, and this information is actually transmitted to the maintenance control section r! ! , 30
Output to.

On the other hand, when a test execution stop is issued from the maintenance control device 30, the test execution stop is transmitted to the test execution management unit 13 via the maintenance control unit 14. The test execution management section 13 sends the communication path control circuit 2 which is executing the test to the test execution control section 12.
Request the suspension of test 2. Also, the test execution information stored in the storage section of the test execution management section 13 is released.

FIG. 2 shows the operation flow of the test execution management section 13, which stores necessary information in the storage section and transmits the start and stop of a test to the test execution control section 12 depending on the control type from the maintenance control section 14.

FIG. 3 is an operational flowchart of the test execution control section 12, which notifies the communication path control circuit 22 of information transmitted from the test execution management section 13. If it is a request to start a test, a determination processing request is sent to the test determination control section 11.

FIG. 4 is an operation flow of the test determination control unit 11, which determines whether the test result is normal or abnormal based on the information received from the communication path control circuit 22, and in the case of abnormality, transmits the cause of the failure to the maintenance control unit 14. .

As described in detail, according to the present invention, the test execution control section, the test execution management section, and the test judgment control section stored in the central control unit of the electronic switching system can control the communication path without using an external installation device. A health test between the control circuit and the communication path equipment can be performed.

Further, according to the present invention, it is possible to discover the cause of the failure after detecting an abnormality in the test results.
