According to the above program loading method, a test program supplied on a floppy disk basis, for example, can be read by the floppy disk drive device 3 of the console 2, and the exchange 1 can execute the read test program.

Therefore, even in exchanges not equipped with a floppy disk drive device, the conventional test program can be used as is.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a configuration diagram of an embodiment of an exchange system in which the exchange main body is not equipped with a floppy disk drive device. In this figure, the same devices as in FIG. 5 are given the same reference numerals and their explanations will be omitted.

The console 22 is installed separately from the main body of the exchange 20, and is equipped with a floppy disk drive device (hereinafter referred to as FDD).
21 (not shown), a keyboard (not shown) for inputting commands etc. from the operator of the exchange 20, a display device, etc., and is constituted by, for example, a personal computer. This console 22 is a data communication control device (D
CC) 18 and a peripheral bus controller (PBC) 13, it is connected to the CPU II.

In the program loading method according to the present invention, for example, a test program supplied on a floppy disk is
The FDD 21 of the console 22 reads the test program, and the read test program can be downloaded from the console 22 to the storage device 12 of the exchange 20. Therefore, a program download function is provided on the console 22 side, and the IPL (initial
program 1 loader) is provided with a function of receiving, storing, and executing a program transmitted from the console 22.

When receiving a program sent from the console 22, the IPL program of the exchange 20 is set to prevent data communication before receiving the program. (DCC) 18 needs to be activated.

FIG. 3 is a flowchart showing the procedure for establishing DCC1B using the IPL program.

First, the IPL program sets in an interrupt controller (not shown) that an interrupt from DCClB has occurred (FIG. 3, Sl). Next, after sending a reset command to DCClB (S2), a start command is sent to start DCClB (S3). At this time, further LCI (line control 1niti)
alize) command to set Decis to the initial state (S4).

Next, the procedure for downloading the test program from the console 22 to the exchange 20 will be explained with reference to FIG.

On the console 22 side, after reading the test program stored on the floppy disk from the FDD 21, it issues a command, for example r D LD, and notifies the CPU II of the exchange 20 of a download request. Assuming that the file name of the test program read at this time is, for example, "B8", rDLD and B8J are input from the console 22.

When a DLD command is input, the console 22 side executes DLD command processing and enters a data transmittable event waiting state in order to wait for a response from the exchange 20 to the download request.

On the other hand, the CPU II of the exchange 20 is in a command waiting state at this time, so the DLD from the console 22 is
When a command is received, control is transferred to data reception processing. In the data reception process, first, a data transmission possible event is returned in response to a download request from the console 22.

When a data transmission possible event is returned from the exchange 20,
The console 22 begins the download process and begins transmitting the test program data.

At this time, the test program data is transmitted from the console 22 in units of the amount of data to be processed when the received data is placed in the storage device 12 on the exchange 20 side.
Once a predetermined amount of data has been sent, the data transmission is temporarily interrupted and an event waiting state is entered.

On the exchange 20 side, the received test programs are sequentially placed in the storage device 12, and when the placement of the received data is completed, a data transmission possible event is sent out again.

On the console 22 side, upon receiving the data transmission possible event, downloading of subsequent test program data is resumed.

In this way, the test program data and the data transmission enable event are exchanged repeatedly between the console 22 and the exchange 20, and when the transmission of all test boot programs 10=program data is completed, the console 22
A download completion notification is sent to the exchange 20.

When the exchange 20 side receives the download completion notification from the console 22, it sends out a data reception processing end event and passes control to the startup process.

On the console 22 side, when the completion of the download process is confirmed by the data reception process end event, the console 22 ends the DLD command process and enters a state of waiting for command input.

On the exchange 20 side, the additional information of the DLD command "
The file name “B8” is searched from the storage device 12, and the file name “B8” is searched from the storage device 12.
8" program and transfer control to it. As a result, the test program sent from the console 22 is started, and after boot processing and initial hardware settings are performed,
A test of switch 20 is performed.

As described above, according to the above program loading method, the test program read by the FDD 21 on the console 22 side can be downloaded to the storage device 12 of the exchange 20, and the exchange 20 can be tested. Therefore, regardless of whether or not the exchange 20 is equipped with an FDD, various programs supplied on floppy disks can be executed.

In addition, since the test program can be input from the console 22 installed away from the exchange 20, tests can be executed and test results can be checked from a location away from the exchange 20, making maintenance and operation of the exchange more efficient. be able to.

It should be noted that the present invention is not limited to the above-mentioned exchanger test program, but can be applied to various programs conventionally supplied to exchangers on floppy disks.

[Effects of the Invention] According to the present invention, a program read from a console installed separately from the exchange can be downloaded to the exchange and tests of the exchange can be performed. Conventional programs can be used as they are even in switching systems that do not have
