DESCRIPTION OF THE PREFERRED EMBODIMENTS [1] Embodiment [1.1] Configuration of Embodiment FIG. 1 is a block diagram showing a configuration of an exchange operation system according to this embodiment. In FIG. 1, the same reference numerals are given to portions corresponding to the respective portions in FIG. 2 described above. Therefore, unless otherwise indicated, the exchange 10, the system file 11, the aggregation device 20, the aggregation device application software 21, the operation protocol conversion unit 22, the exchange protocol conversion unit 23, the operation protocol conversion unit 32, and the exchange protocol conversion unit 42 It has the same functions and performs the same operations as those shown in "Prior Art".

The configuration of this embodiment differs from that of FIG. 2 only in the configuration of the operation terminal 30. Here, the operation terminal 30
Is connected to the exchange 10 via the communication line 52 and the communication line 5
3 and connected to the aggregation device 20. The operation terminal 30 is provided with both an operation protocol converter 32 and an exchange protocol converter 42, and terminal application software 33 is installed. The terminal application software 33 installed in the operation terminal 30 is used when the operator performs maintenance work such as correction of the system file 11 in the exchange 10.
It is application software to support it. The terminal application software 33 is
The configuration is such that both the operation protocol converter 32 and the exchange protocol converter 42 can be used.

[1.2] Operation of Embodiment In this embodiment, when the aggregation device 20 is functioning normally, maintenance work is performed via the aggregation device 20 and the aggregation device 20 is broken. In this case, the maintenance work of the exchange 10 is performed directly via the communication line 52. In the operation terminal 30, when performing maintenance work via the aggregation device 20, the operation protocol conversion unit 32 is selected. On the other hand, when the maintenance work is performed without passing through the aggregation device 20, the exchange protocol conversion unit 42 is selected in the operation terminal 30.

As described above, in the present embodiment, the aggregation device 2
The protocol converter is changed depending on whether or not it passes through 0. Hereinafter, a method of selecting the protocol converter will be described. First, the operator operates the keyboard or the like of the operation terminal 30 so that the exchange 1
When an address of 0 is designated and a transfer request for a program to be corrected by the exchange 10 is input, the operation terminal 30 requests the aggregation device 20 to transfer a program to be corrected.

When the aggregation device 20 is operating normally,
The aggregation device 20 responds to this transfer request. As described above, when there is a response from the aggregation device 20 side, the operation terminal 30 performs the maintenance work of the exchange 10 using the operation protocol conversion unit 32 as it is. In this case, the exchange operation system according to the present embodiment performs the same operation as in the case of performing the maintenance work using the operation terminal 30 in the “prior art”.

On the other hand, if the aggregation device 20 has failed, the aggregation device 20 does not respond to the transfer request. As described above, when the response from the aggregation device 20 is not made, the operation terminal 30 switches the operation protocol conversion unit 32 to the exchange protocol conversion unit 42. When the switching to the exchange protocol conversion unit 42 is performed, the operation terminal 30 requests the exchange 10 again to transfer a program to be corrected. Thus, when the switching of the protocol conversion unit is completed, the maintenance work of the exchange 10 by the operation terminal 30 becomes possible.
In this case, the operator uses the operation terminal 30 to perform the maintenance work of the exchange 10 directly without going through the aggregation device 20.

As described above, the exchange operation system according to the present embodiment enables the operation terminal to communicate with the exchange protocol and the operation protocol by using two protocols. In some cases, the system file of the exchange can be corrected. Also, since only one terminal application software is required, development costs can be reduced. Further, even in the event of a failure of the aggregation device, the same terminal can be used to perform an operation using the same GUI, thereby improving the operability of the operator.

In this embodiment, the exchange 1 and the central office 2 are configured to communicate with each other by the dedicated line 51 and the communication line 52. However, the exchange protocol is TC.
In the case of the P / IP protocol, it is possible to use these two lines as one dedicated line. Further, even when the exchange 10 having a unique communication protocol is accommodated, if the protocol conversion unit is added to the operation terminal 30, the terminal application software 33 can support two or more communication protocols. is there.

Further, in the present embodiment, the updating of the system file has been described as an example, but the maintenance work of the present invention is not limited to this and includes other works.

[0030]

As described above, according to the exchange operation system according to the present invention, the operation terminal can communicate with the exchange protocol and the operation protocol, thereby eliminating the need for an alternative operation terminal. In addition, even when the aggregation device fails, the system file of the exchange can be corrected.
Further, even when upgrading the system file of the exchange, only one application software for the terminal is required, so that the development cost can be reduced. In addition, even when the aggregation device fails, the same G
The operation can be performed using the UI, and the operability of the operator can be improved.
