DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for reading out the connection state of a communication path switch in a telephone switchboard of a storage program control type.

[0002]

2. Description of the Related Art Conventionally, in reading out the connection state of this kind of communication path switch, a tester connects an in-circuit emulator (ICE) to an exchange and uses this ICE to read a read address of a storage device of the exchange. The specified data is read from the specified address.

[0003]

In the above-mentioned conventional reading of the connection state of the speech path switch, the ICE is connected to the exchange, and the tester must read the address while calculating the read address in the switch memory. It was troublesome. In addition, in order to connect the ICE, the exchange must be stopped once, and there is a problem that the connection state of the subscriber having a call failure cannot be read during the operation of the exchange.

An object of the present invention is to use a maintenance terminal of an exchange to connect a communication path switch that allows the maintenance terminal to easily display a connection state of the communication path switch and a destination identified from the connection state. A state reading method is provided.

[0005]

According to the present invention, there is provided a method for reading out a connection state of a communication path switch, comprising the steps of: identifying a predetermined operation input to the maintenance terminal; Connection state reading means for outputting a read instruction signal to the switch to receive connection state information between the input / output terminals of the communication path switch from the connection state detecting means of the exchange, and connecting state information output from the connection state reading means. Connection destination identification means for editing the number information and connection information to be displayed on the maintenance terminal, and connection state display control means for displaying and controlling the number information and connection information edited by the connection destination identification means , Security
Terminal on the switch memory of the designated exchange.
The read contents at the address and the designated exchange
Both of the connection state read contents of the communication channel switch
Is that displays instructions configured on the connection state display control means results.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the configuration of a switching system according to an embodiment of the present invention, FIG. 2 is a diagram showing the configuration of a switch memory in a storage device in FIG. 1, and FIG. FIG.

In FIG. 1, an electronic exchange 1 accommodates a subscriber 3 and a subscriber 4 and is connected to a maintenance terminal 2. The electronic exchange 1 includes a communication path switch 8 that forms a communication path between the subscribers 3 and 4, a storage device 5 including a switch memory 6 that stores a connection state of the communication path switch 8, and a central processing unit that controls these. Device 7. In this example,
FIG. 2 shows an example in which the switch memory 6 includes a primary switch memory 12, a secondary switch memory 13, and a tertiary switch memory 14 corresponding to the communication path switch 8. The switch 8 includes a primary switch 15, a secondary switch 16, and a tertiary switch 17 as shown in FIG.
Is shown. Here, it is assumed that the subscribers 3 and 4 are connected.

The maintenance terminal 2 identifies the operation input from the tester, and sends a read instruction signal including the number of the subscriber 3 to the central processing unit 7 of the electronic exchange 1 to switch the communication path of the subscribers 3 and 4. And a connection destination reading unit for editing the connection state information output from the connection state reading processing unit into number information and connection information for display on the maintenance terminal 2. Processing unit 10
And a connection status display processing unit 11 for controlling display of the information edited by the connection destination identification processing unit 10.

The operation will be described below. When the tester inputs the telephone number of the subscriber 3 and a command for reading from the maintenance terminal 2 during the operation of the electronic exchange 1, the connection state read processing unit 9 identifies this. The connection state read processing unit 9 calculates the address of the switch memory of the subscriber 3 using a built-in comparison table (not shown), and transmits the read address to the central processing unit 7. Central processing unit 7
Are the primary switch memory 12 and the secondary switch memory 13
Then, the tertiary switch memory 14 is searched, and the contents of the specified address are read out and returned to the connection state read processing unit 9.

The connection destination identification processing section 10 edits information output from the connection state reading processing section 9, and the connection state display processing section 11 uses the edited information as the connection state of the communication path switch and displays the screen of the maintenance terminal 2. To be displayed. At this time, connection destination information converted from the read information by the connection destination identification processing unit 10, in this case, the number of the subscriber 4, is also displayed. When the subscriber 3 is connected to a subscriber of another station, for example, the trunk number connected to the other station is displayed.

After completion of the processing of the connection state display processing section 11, the connection state reading processing section 9 continues to switch the switch order on the call path switch of the subscriber 3 based on the telephone number of the subscriber 3 already inputted. It is calculated by a built-in comparison table (not shown), and transmitted to the central processing unit 7 in the same manner. The central processing unit 7 scans the primary switch 15, the secondary switch 16 and the tertiary switch 17 according to the designated order, and returns a read result to the connection state read processing unit 9. Subsequent operations are the same as those described above, and a description thereof will be omitted.

As described above, the test is performed continuously, and usually,
The tester confirms that the results of both the software (switch memory) and the hardware ( communication path switch) match as described above, and ends the test. If the results do not match, it means that a failure has occurred, and the tester can limit the applicable location to check.

[0014]

As described above, according to the present invention, a read instruction signal for reading out the connection state of the speech path switch from the maintenance terminal connected to the exchange is sent to the connection state detecting means of the exchange to check the connection state. By reading and displaying the information on the maintenance terminal, it is possible to easily see the connection state without any knowledge about the switch memory of the exchange. And I
Since there is no need to connect the CE, the reading can be performed without stopping the exchange. Further, for example, by reading the connection status of a subscriber who has a trouble in a call, there is an effect that it can be used for trouble analysis.
