The existing AP board 2 is an AP board that is already installed and operating in the apparatus, and the new AP board 3 is an AP board that is newly installed in the apparatus.
And the new AP board 3 operate by the same program. The existing AP board 2 and the new AP board 3 are A
The type numbers 22 and 23 representing the types of P boards are the same, and are identified by the individual board numbers 13 and 19 from the main control board 1.

The existing AP board 2 and the new AP board 3
Is a memory 12 in which only the minimum basic program data necessary to execute the copy between the microprocessors 8 and 14 and the AP board and to activate the program data stored in the memories 11 and 17 is written in advance.
18 is mounted.

Data highway interface 10, 1
Reference numeral 6 is an interface circuit that controls the transfer of data between the channels assigned to each AP board and the microprocessors 8 and 14 on the data highway 21.

Next, the operation of this embodiment will be described in detail with reference to the drawings. FIG. 2 is a sequence diagram showing a sequence in which program data is transferred from the existing AP board 2 to the new AP board 3 when the new AP board 3 is mounted.

When a new AP board is mounted on the electronic exchange device, the microprocessor 4 is installed in the main control board 1.
The new board mounting detection processing via the control bus 20 by the CPU mounts the new AP board 3 and its type number 23.
Is detected, and then a search process is performed to determine whether or not an AP board having the same type number as the AP board newly detected by referring to the mounting information memory 6 and operating by the same program exists in the device. It

When the existing AP board 2 operating with the same program as the AP board newly installed in the apparatus is detected, the main control board 1 detects the existing AP board via the control bus 20.
An instruction for activating the process of transferring the program data stored in the memory 11 is issued to the board 2, and at the same time, the board number 19 of the AP board that is the transfer destination and the time-division data highway 21 used for the data transfer. Notify the channel number above.

As a result, the existing AP board 2 shifts to a processing state of transferring its own program data to the new AP board 3 in parallel with the original processing as an application. At this time, when there are a plurality of existing AP boards that operate according to the same program, the main control board 1 treats the existing AP board having the lowest board number as the transfer source.

When it is confirmed that the existing AP board 2 has started the process as the transfer source of the program, the main control board 1 similarly activates the program data receiving process for the new AP3 board via the control bus 20. An instruction is issued, and at the same time, the board number 13 of the transfer source AP board and the channel number on the time division data highway 21 used for data transfer are notified.

When it is confirmed that the program data transfer processing has been started by both the existing AP board 2 and the new AP board 3, the main control board 1 transfers the data highway between the transfer source / transfer destination AP boards. 21 time-division switch 7 to connect to each other on the specified channel
Set. When the AP boards, which are the data transfer source / transfer destination, are connected to each other on the data highway 21 by the setting of the time division switch 7, the main control board is already installed.
A data transfer / reception start command is issued to both the P board 2 and the new AP board 3.

By the above operation, the existing data transfer source A
Since the P board 2 and the transfer destination new AP board 3 are connected to each other via the data highway 21, subsequent program data transfer processing is performed by the data highway interfaces 10 and 16 and the data highway 21. It is carried out by direct communication between both transfer destination boards.

When the transfer of all necessary program data is completed by direct communication between the AP boards, the existing AP
Both the board 2 and the new AP board 3 notify the main control board 1 via the control bus 20 that the transfer is completed, and the main control board 1 receives the notification to set the time division switch 7. After the cancellation, a command to complete the data transfer process is issued to the existing AP board 2, and the new AP
With respect to the board 3, the data reception process is terminated, and an instruction to switch the operation is issued to the application program stored in the memory 17 by the transfer process up to this point.
As a result, the existing AP board 2 returns to the operating state of only the original processing as an application, and the new AP board 3 starts operating by the program transferred by the above-mentioned operation.

Further, when data is transferred to a plurality of new AP boards at a time, the main control board 1 detects the first new AP board in consideration of the fact that a plurality of new AP boards are mounted. After the new board is detected for a certain period of time, the process proceeds to the next process, and all the new AP boards detected during the certain period are targeted for program transfer.

As described above, the present invention has the following effects. The first effect is that when an AP board is newly mounted on the device, if an AP board of the same type that operates with the same program is already operating in the device, the AP board is newly mounted. To do this, only the work of mounting the board on the device is necessary, and the work of downloading the program from the external terminal via the processing of the main control board is not required. Therefore, the maintenance and operation work related to the addition of the AP board can be simplified. It means that you can
