[Industrial application field]

The present invention relates to a peripheral device accommodating system, for example, a peripheral device accommodating system that uses a digital exchange and allows peripheral devices connected thereto to be exchanged with each other.

[Prior Art] Data processing devices equipped with various peripheral devices (printers, hard disk devices, floppy disk devices, etc.) can now be connected to known digital exchanges via intervening communication lines. It can accommodate multiple peripheral devices.

For example, as shown in FIG. 7, there is a digital exchange 420 connected to a certain central office line 211 and accommodating a plurality of extension telephones 213. This digital switch 420 has a central office trunk (COT) 42 connected to a central office line 211 that is connected to other similar digital switches (not shown).
1 and an extension subscriber circuit accommodating a plurality of telephones 213 (
LC) 423, a switching network (NW) 425 that performs switching between these multiple subscribers and other stations, a control device (CC) 427 that controls line connections in the switching network 425, and a control device (CC) 427 that operates this control device 427. It includes a main memory (MM) 429 in which programs and various information are stored, and a data access unit (DAU) 431 interposed through a communication line exchanged by the digital exchange 420.

In this digital exchange 420, one data processing device section 440 is connected to one terminal (peripheral device connection terminal) which is a communication line in which a data access unit 431 is installed. This data processing unit 440 is also a peripheral device accommodated in the digital exchange 420.

The data processing unit 440 includes an interface (IF) 441 provided for connection with the outside, and a central processing unit (CPU) 4 that controls the entire data processing unit 440.
43, a storage device (memory) 445 in which a program for operating the central processing unit 443 and various control information can be stored, a display device 447 for displaying input data, processed data, etc.; It includes a keyboard 449 for inputting input, control commands, etc., a printer 451 for printing data to obtain a hard copy if necessary, and a hard disk device 453 and a floppy disk device 455 for storing data. These interfaces 441, central processing unit 443. Storage device 4452 Display device 447. Keyboard 449. Printer 451, hard disk device 453. Floppy disk devices 455 are connected to each other by a common bus 457.

However, the interface 441. Central processing unit 443, storage device 4451 display device 447 and keyboard 449
The main body is constructed independently. Also, the printer 451. Hard disk device 453. Each of the floppy disk devices 455 is configured separately and is connected to each other so as to serve as a peripheral device for the main body. The main body of the data processing device section 440 can be connected via a common bus 457 extending to the outside.

In the digital exchange 420 and data processing unit 440 configured in this way, the digital exchange 42
0, the data processing device section 440 is treated as one unit.

For example, when the data processing unit 440 is called via another digital exchange via the central office line 211, a communication path is formed by the digital exchange 420, and data is written to the floppy disk device 455 of the data processing unit 440. think of. The control device 427 analyzes the destination and forms a communication path for the data processing device section 440, which is the destination, and the data processing device section 440 is accessed by the data access unit 431. Accordingly, data is written to the floppy disk device 455 under the control of the central processing unit 443 of the data processing unit 440.

[Problems to be Solved by the Invention] By the way, in the conventional data processing unit 440 described above, when the data processing unit 440 is called, the communication line for accessing it is secured, and then the data processing unit 440 is called. The data processing unit 440 is accessed by the data access unit 431 .

In that case, the data processing unit 440 is integrated with the floppy disk device 455 and occupies the communication path used by the data processing unit 440, so data is not written to the floppy disk device 455. Other peripheral devices (hard disk device 453)
．． printer 451 etc.) cannot be used independently. In other words, there is a problem in that if one of the peripheral devices or the main body of the data processing device section 440 is used, the others cannot be operated in parallel.

The present invention was created in view of the above points, and an object of the present invention is to provide a peripheral device storage system that allows each of a data processing device or its peripheral devices to operate in parallel.

The signal is supplied to the data interface unit 1-233 through the data interface unit 233 □ of the switching network 225 through the connection path (indicated by ■) of the switching network 225 . Further, since the printer 251 is accessed by the central processing unit 243 via the data interface unit 233I, the data read from the hard disk drive 253 is transferred to the data interface unit 233. is applied to the printer 251 and printed.

In this way, for the data processing device 240, the floppy disk device 255, hard disk device 253, . Printer 251 operates in parallel.

Benefits iii) Actual Basis In the example described above, there is one data processing device 240, but there may be a plurality of data processing devices 240. In the embodiment shown in FIG. 6, the digital exchange 220 includes two data processing devices 240. and 240□ to the peripheral device connection terminal,
The connection is made by exchange w4225 under the control of the control device 227 (indicated by ■ and ■).

The hard disk device 2 is processed by the data processing device 240I.
This is a case where the data already stored in the hard disk drive 253 is read out and sequentially displayed on the display device 247. Furthermore, this is an example in which the floppy disk device 255 is accessed by another data processing device 24oz, and data in the floppy disk device 255 is edited.

In this way, separate processing by the two data processing devices 240 can be performed in parallel.

Hard disk device 253. The printer 251 performs other processing in parallel (printout of stored data)
can be done.

Further, since each peripheral device is simply connected arbitrarily to the peripheral device connection terminal of the data interface unit 233 included in the digital exchange 220, it operates at a separate location from the data processing device 240, and even if the keyboard 249
Remote operation is possible even from a different location.

Note that this is not limited to the peripheral devices in the embodiment of the present invention described above, but may be other peripheral devices such as a tape league, and the device connected as the data processing device 240 is a data interface.
