DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subscriber circuit of an electronic exchange. The present invention is used for adding or changing a subscriber circuit.

[0002]

2. Description of the Related Art When a subscriber circuit is added, abolished, or changed, an operator directly accesses a hardware subscriber circuit to change a device and a database for supplying information to a central control unit. The stored station data must be changed. The change of the station data is also performed by inputting information on the installation state of the subscriber circuit and type information of the subscriber circuit by a command operation of the operator. Therefore,
There may be a case where the actual hardware status and the station data stored in the database do not match due to a human error.

As a technique for preventing the occurrence of the inconsistency, Japanese Patent Laid-Open Publication Nos.
The techniques described in JP-A-8895, JP-A-1-248788 and the like are known.

[0004]

Generally, a database for storing station data so that the station data is not lost, and system operation can be continued even if a part of the station data is damaged. Has a configuration based on a duplex system for performing a synchronous operation of two memory devices. In this case, in the conventional method, the change of station data involves command operation input. Therefore, even when the database is duplicated, the synchronous operation of both systems is temporarily stopped to make it a single system operation, and the data is written. After the copying is completed, the copying operation is executed to return to the duplex synchronous operation.

[0005] Therefore, if any trouble occurs in the database during the operation of changing the station data, there is a possibility that the system operation will be stopped. Further, the number of man-hours for inputting operation is large.

Further, in the above-mentioned prior arts for preventing the state of the hardware from being inconsistent with the station data stored in the database, any of the above-mentioned prior arts indicates the inconsistency by processing on the data. However, this does not mean that a test is actually performed on hardware to confirm that there is no mismatch.

SUMMARY OF THE INVENTION The present invention has been made in such a background, and it is intended to eliminate inconsistency between the state of the hardware set in the subscriber circuit and the station data input to the database, and to provide the database. It is an object of the present invention to provide an exchange which can change the office data in a state where the synchronous operation is performed.

[0008]

SUMMARY OF THE INVENTION The present invention comprises a central controller (1), a database (7) connected to the central controller and holding station data, and a subscriber circuit controlled by the central controller. Group (2-1, 2-2, 2-3, ...)
, 2-n), means (4) for reading the installed state of the subscriber circuit and the type of the subscriber circuit from the group of subscriber circuits, and controlling the central control device (1). Means for editing and temporarily storing the data obtained from the reading means as station data, and executing a test corresponding to the subscriber circuit type based on the data held by the edited and temporarily storing means. Means (6), and means for writing data consistent with the results of this test as station data into the database (7).

The database (7) is constituted by a duplicated memory, the writing means includes a means for executing the duplicated memory in a both-system synchronous operation state, and the means (6) for executing the test includes the subscriber. Desirably, the circuit includes means for generating an interrupt pseudo call.

[0010]

According to the present invention, with the addition or change of the subscriber circuit,
The data corresponding to the station data is once edited and temporarily stored. Then, a test is automatically executed on the hardware based on the data, and the data temporarily retained is written to a database for a result of the test that is normal. This writing is not performed by an operation command, but is automatically executed by software control for a test result that is normal. Therefore, even when the database performs the duplex synchronous operation, the synchronous control can be continued, so that it is not necessary to temporarily change to the single system operation when writing or changing the station data.

[0011]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the embodiment of the present invention.

The embodiment of the present invention comprises a central controller 1, a database 7 connected to the central controller 1 and holding station data, and subscriber circuit groups 2-1, 2 controlled by the central controller 1. , 2-3,..., 2-n. Further, as a feature of the present invention, the subscriber circuit group 2-
.., 2-n are provided with reading means 4 for reading the mounting state of the subscriber circuit and the type of the subscriber circuit, and are obtained from the reading means 4 under the control of the central controller 1. Editing and holding means 5 for editing and temporarily storing the edited data as station data, test execution means 6 for executing a test corresponding to the subscriber circuit type based on the data held by the editing and holding means 5, Means for writing data with no contradiction to the database 7 as station data. The database 7 is constituted by a duplicated memory,
The writing means includes means for executing the duplicated memory in the both-system synchronous operation state, and the test execution means 6 includes means for generating an interrupt pseudo call to the subscriber circuit.

Next, the operation of the embodiment of the present invention thus configured will be described. FIG. 2 is a flowchart showing the operation flow of the embodiment of the present invention.

The control order from the central control device 1 to the subordinate device is sent to the operation control circuit 3 via the interface circuit 8. The operation control circuit 3 analyzes the order, and if it is a call processing order, the subscriber circuits 2-1 to 2-2.
-N is controlled. If it is a reading order, the reading unit 4 is controlled. The reading means 4 started by the operation control circuit 3 collects information on the mounting, non-mounting, and type of the subscriber circuits 2-1 to 2-n, and performs central control via the operation control circuit 3 and the interface circuit 8. The collection result is reported to the device 1. The central control device 1 that has received the collection result controls the editing and holding unit 5 to edit the information, and the editing result is temporarily stored in the editing and holding unit 5.

Next, the central control unit 1 fetches the editing result for each subscriber circuit from the editing and holding means 5 and, if mounted, the type of the subscriber circuit (for example, A, B,... X).
Is selected, and the test execution means 6 is started. The test control order from the central controller 1 to the test execution means 6 is also performed via the interface circuit 8.

The test executing means 6 started by the central control unit 1 makes an interrupt pseudo call to the designated line of the subscriber's circuits 2-1 to 2-n. At this time, the operation control circuit 3 operates in the same manner as the general call processing and transmits a call to the central control device 1. The central control unit 1 transmits the designated subscriber circuits 2-1 to 2-
When the call from n is recognized as normal, the editing result is kept as it is, and when it is recognized as abnormal, the editing and holding means 5 is controlled so that it is re-edited as not mounted and stored in the database 7.

[0017]

As described above, according to the present invention, since the central control unit confirms the normality of the subscriber's circuit and generates the station data, there is no inconsistency with the actual mounted state, and the artificial data is eliminated. Error-free station data can be stored in the database, which makes it possible to store data even in a duplicated database during synchronous operation, avoiding the danger of system failure in the event of a failure, and maintaining There is an effect that man-hours can be reduced.
