In order to write and read stored data from the data input/output board to the data storage device, there are certain input operation procedures that differ depending on the type of data being handled. To make changes, maintenance personnel who are skilled in operating the data input/output board are required and it is time consuming.

SUMMARY OF THE INVENTION An object of the present invention is to provide a data processing device connection method that eliminates the above-mentioned drawbacks and allows easy connection of stored data by connecting a general data processing device to a data input/output board. Achieving the above object The features of the present invention include a keypad for inputting data, a data display lamp for displaying data, and a key input from the keypad when reading and writing data to a data storage device in an automatic exchange. a data input control circuit that controls data;
In a data input/output table having a data output control circuit that controls data display on a data display lamp, and a control circuit that controls the data input/output,
A communication control circuit for connecting with an external data processing device, a data input control circuit that can be switched to control input data sent from the data processing device, and a data input control circuit that can control data output to the data processing device. By providing a switchable data output control circuit, input data sent from a data processing device connected to the communication control circuit instead of input from the keypad and display instead of data display on the data display lamp can be used. The object of the present invention is to read and write stored information in a data storage device by outputting data contents to a data processing device.

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 3, exchange processing processors 301 to 30n that perform exchange processing services
refers to the data stored in the data storage device 310 via the bus 311 as necessary.

In order to read and write this stored data, external data processing device 312 transmits necessary input data to data input/output board 313. The data input/output board 313 that has received the input data transfers it to the interface processor 314 after preparing the data necessary for reading and writing the data. The interface processor 314 uses the bus 311
Data is read from and written to the data storage device 310 via the data storage device 310. The interface processor 314 that has read the stored data transmits the read data to the data input/output board 313. The data input/output board 313 that has received the data transfers the data to the external data processing device 312.

The operation of the data input/output board will be explained in more detail with reference to FIG. The data input/output board 400 transmits and receives data to and from an external data processing device via a communication control circuit 401.

Data input control circuit 403 that conventionally controlled key input data from keypad 402
controls input data sent from the data processing device via the communication control circuit 401. The data input control circuit 403 that has received the data outputs it to the control circuit 404 in the same data format as when the data is input from the keypad 402. Therefore, the control circuit 404 performs the same processing as in the case of key input from the keypad 402, and transfers the data to the interface processor. Note that the data input control circuit 403 is
It can be switched to control key input data from keypad 402 in a conventional manner.

Next, when receiving read data from the interface processor, control circuit 404 transfers the read data to data output control circuit 405.
A data output control circuit 405, which conventionally controlled data display on a data display lamp, outputs received data to an external data processing device via a communication control circuit 401. Data output control circuit 405
can be switched to display data using a data display lamp 406 in the conventional manner.
The data transferred from the control circuit 404 to the data output control circuit 405 is exactly the same as when displaying conventional data on the data display lamp 406, and when transferring to an external data processing device, there is no difference in the processing, so the conventional data The control circuit can be used as is.
By storing the data input/output operation procedure using the keypad 402 and data display lamp 406 in an external data processing device, it becomes possible to write and read advanced data with simple operations from the input/output equipment in the data processing device. . Further, by switching between the data input control circuit 403 and the data output control circuit, conventional data input/output operations according to key input using the keypad 402 and data display using the data display lamp 406 are also possible. Regarding the type of data processing device connected to the outside, by changing only the communication control circuit 401, various transmission control procedures can be used, and various existing data processing can be effectively used.

As explained above, the present invention connects a general data processing device to a data input/output board.
This has the effect of simplifying and speeding up the rewriting of stored data in an automatic exchange, and making effective use of existing data processing equipment to facilitate maintenance of the automatic exchange.
