【The invention's effect】
As described above, the present invention provides an update instruction including download information necessary for downloading update data from a distribution device via a data communication network to a key telephone device via a telephone network. A management device having a management control unit for transmitting is provided, and update control means of a main device of the key telephone device transmits data from the data communication network to the data communication network based on the download information included in the update instruction received from the management device via the telephone network. And downloads the update data to a key telephone device via a data communication network in a distribution control unit of the distribution device.
[0059]
Therefore, the time required for transmitting the update data can be significantly reduced as compared with the case where the update data is transmitted via the telephone network. Further, the distribution device only needs to manage the telephone numbers of the button telephone devices that are hardly changed, and it is not necessary to manage network addresses that are more likely to be changed than the telephone numbers.
Thus, even when the network address of the key telephone device is dynamically assigned, the distribution of the program and the setting information from the distribution device to the key telephone device via the data communication network is not required without the need for the address notification work by the administrator. Update data can be downloaded efficiently and easily.
