Abstract

PURPOSE:To easily exchange a key telephone system by providing a control means to identify the code of the exchange key telephone system, and to automatically change the telephone set code of a key telephone system code memory storing the function data of respective keys in the key telephone system. CONSTITUTION:When a key telephone system 100 is detached from a main unit 200 and a key telephone system 300 is connected, the telephone set code is read out from a ROM 302, which registers the telephone set code, and transmitted through a data transmission part 201 to the main unit 200. when this telephone set code is received through the data transmission part 201, the main unit 200 transmits this code to a control part 202 and the control part 202 changes the telephone set code, which is provided in a memory area 204 of the key telephone system 100 as the transmitting source, in a storage part 203 from the transmitting source of the transmitted telephone code. When the key telephone system is exchanged from a low-grade key telephone set, for which the number of function keys is small, to a high-grade key telephone system with a lot of the function keys, the key telephone system can be used and in the case of reverse exchange, the allocation of the function keys is set to be suitable for the low-grade key telephone system. Afterwards, the key telephone system can be used.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a key telephone device having a switching function and a main device and a key telephone set for use within the premises of an office or the like.

BACKGROUND OF THE INVENTION Conventionally, there have been button telephone devices that can control and use both high-end button telephones with a large number of function buttons and low-grade button telephones with a small number of function buttons. When replacing a high-end button telephone with many function buttons for a low-class button telephone with few function buttons, or replacing a low-class button telephone with few function buttons with a high-end button telephone with many function buttons, Change the button telephone code in the button telephone code memory in the main device in which the relevant button telephone code is stored to the newly replaced button telephone code, and the contents of the function memory of the button telephone in which the functions of the relevant button telephone are stored. cannot be used unless you change the settings to match the newly replaced phone.

Problems to be Solved by the Invention However, in the above conventional structure, each time a key telephone is replaced, the code and function settings of the new key telephone are stored in the key telephone code memory in the main device. If key telephones are frequently replaced, the replaced key telephone codes and functions must be reconfigured many times.

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention provides a button telephone that identifies the button telephone code when the telephone is replaced and stores the function data of each button of the corresponding button telephone. Control means are provided for changing the button telephone code in the code memory to a newly replaced button telephone code.

Effect of the Invention With the configuration described above, the present invention automatically updates the function data corresponding to each button of the key telephone when replacing the key telephone, thereby guaranteeing the operation of the key telephone.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows the configuration of the main device and the key telephone in an embodiment of the present invention, Fig. 2 shows the flow when removing the key telephone from the main device, and Fig. 3 shows the flow when removing the key telephone from the main device. The processing flow when connected to the device is shown. 100 is a button telephone.

Reference numeral 101 denotes a data transmission unit that sends and receives data such as button information to and from the main device. Reference numeral 102 is a ROM in which the button telephone code is registered. 103
is a control unit which includes the data transmission unit 101 and the ROM 102.
This is the part that controls the 200 is the main device. 201
is a data transmission section which transmits and receives data such as key telephone code information of the key telephone 100 to and from the main device 200. Reference numeral 202 denotes a control section that performs exchange processing using a storage program method and controls the data transmission section 201, data transmission section 204, and storage section 203. Reference numeral 203 denotes a storage unit that stores information necessary for the exchange operation. 204 is a memory area of the key telephone. 300 is a button telephone. Reference numeral 301 is a data transmission unit that sends and receives data such as button information to and from the main device. 302 is a ROM in which the button telephone code is registered. Reference numeral 303 denotes a control section that controls the data transmission section 301 and the ROM 302.

In order to explain the present invention in the button telephone device of this embodiment configured as described above, its operation and control process will be explained below based on FIGS. 1, 2, and 3. .

First, regarding the process when removing a button telephone from the main device, when the button telephone 100 is removed from the main device 200 in order to replace the button telephone 100 currently in operation with another button telephone 300, the main device 20
0 determines that data transmission is not possible (step 40).
1) Set an unusable flag in the memory area of the key telephone (step 402).

Next, regarding the process when another key telephone 300 is newly connected to the main device, when the key telephone 300 is connected to the main device 200 (step 501), the telephone code is read from the ROM 302 in which the telephone code is registered ( Step 502). The telephone code is sent to the data transmission section 30.
1 to the main device 200 (step 503).
. The main device 200 receives the telephone code sent from the key telephone 'a300 via the data transmission section 201 (step 504). The data transmission unit transmits the telephone code to the control unit 202, and the control unit 202 changes the telephone code provided in the memory area 204 of the transmission source button telephone 100 in the storage unit 203 from the transmission source of the transmitted telephone code. (Step 505). Determining whether to replace a low-grade button telephone with a small number of function buttons to a high-grade button telephone with a large number of function buttons (step 506), when replacing a low-grade button telephone with a small number of function buttons to a high-grade button telephone with a large number of function buttons, The key telephone is enabled for use (step 508).

When replacing a high-grade button telephone with a large number of buttons to a low-grade button telephone with a small number of function buttons, the allocation of function buttons is set to match the low-grade button telephone (step 507). Thereafter, the key telephone is enabled for use (step 508).

Effects of the Invention As described above, the present invention enables the replacement of a low-end telephone with few function buttons to a high-end telephone with many function buttons, enabling all the functions of a low-class button telephone with few function buttons, Replacing a high-end button telephone with many function buttons to a low-class button telephone with few function buttons automatically enables the functions that can be performed within the range of the low-class button telephone, making it easier to replace the button telephone.

As described above, the present invention has great practical effects when operating a key telephone.
