Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a button telephone device installed in a premises such as a business office and having a large number of extension telephones. 2. Description of the Related Art Some conventional button telephone devices have individual control data for each extension so that each extension terminal can have an individual function according to the convenience of the user, and normally operates according to this control data. ing. For example, when the extension telephone housed in the key telephone device is moved when relocating the workplace, it is necessary to move the control data together with the movement of the telephone itself. Conventionally, this work is performed from maintenance equipment such as maintenance panels and terminals with CRT.
The control data of the key telephone device was rewritten using a command dedicated to maintenance. Problems to be Solved by the Invention However, in the above-mentioned conventional method, since specialized knowledge is required regarding maintenance of the key telephone device, in order to move the extension telephone, it is necessary to request a maintenance administrator. However, there is a problem in that the extension telephone cannot be easily moved by the hand of a general user when the workplace is relocated. In addition, even if they have specialized knowledge, there is a problem in that data is erroneously set when rewriting control data. In order to solve this, as shown in Japanese Patent Laid-Open No. 60-208193, an extension terminal is provided with means for setting a terminal unique code, and the main device is provided with this terminal unique code and control data. When an extension terminal is connected, the extension terminal transmits the terminal unique code to the main unit side, and the main unit refers to the table and controls data corresponding to the terminal unique code. There is a system that automatically responds to the movement of the extension terminal by performing the control according to the above, and can respond to the movement of the extension without any operation from the maintenance device or the like. However, with this configuration, each extension terminal has its own terminal-specific code set, so that the user or administrator must identify which extension terminal and which terminal-specific code to prevent duplicate terminal-specific codes. It is necessary to manage whether or not the user has a telephone number, and especially in the case of a key telephone device in which the number of extension terminals is large, the management is very troublesome. In view of the above conventional problems, the present invention has a plurality of extension interface circuits that respectively connect to different extension terminals, and a certain extension terminal is different from the extension interface circuit that has been connected until now. In the key telephone device that can automatically move the control data of the extension terminal even if it is connected to the extension interface circuit, the extension terminal does not have to manage which terminal unique code is attached to the extension terminal. It is an object of the present invention to provide a key telephone device that can automatically respond to movements of machines. Means for Solving Problems In order to solve the above-mentioned conventional problems, the control unit of the main device allocates a terminal-specific code to each extension terminal, and the extension terminal is unique to the terminal. The code storage unit is made rewritable, and the terminal-specific code allocated by the main unit is stored in this storage unit, and the terminal-specific code is stored and held even when not connected to the extension interface circuit. Operation In the present invention, since the main unit automatically allocates the terminal unique code of each extension telephone by the above-mentioned configuration, it is not necessary to set the terminal unique code in each extension telephone. Embodiment 4 FIG. 4 shows a system configuration of a key telephone device according to an embodiment of the present invention. In FIG. 4, 100 is a main unit, and 101 to 104 are extension telephones connected to extensions of the main unit 100. Main device 1
00 is an extension telephone comrade, between 101 and 104, and extension telephone
Connection between 101 to 104 and the outside line 105. FIG. 5 is a block diagram showing the functions of one of the extension telephones 101 to 104, the control unit of the main apparatus 100, and the extension unit. In the main unit 100 of FIG. 5, 111 to 114 are extension interface circuits for performing data communication between the main unit 100 and extension telephones 101 to 104, 115
Is a control unit for performing exchange control by a microcomputer, and 116 is a storage unit for storing data necessary for performing exchange control. On the other hand, in the extension telephone 101, 117 is a data transmission circuit for performing data communication with the main device 100, 118 is a key input circuit for inputting selection signals and the like, 119 is an LED display circuit for displaying the usage status of the line, 120 Is an I / O interface circuit. Reference numeral 121 denotes a control unit of the extension telephone set 101 configured by a microcomputer, which drives an LED display circuit 119 based on a command from the main device 100 and a key input circuit.
The main device 100 is notified of the input information from 118. Reference numeral 122 is a storage unit for storing data sent from the main device 100, and 123 is a backup power supply for preventing the data in the storage unit from being erased. The operation of the key telephone device of this embodiment constructed as described above will be described below. First, the start-up of the key telephone system will be described with reference to FIG. Main system 10 at system startup
The control unit 115 of 0 is the extension telephones 101 to 101 that can be accommodated in the main device 100.
As many as 104 terminal-specific codes are generated, and each terminal-specific code is assigned to each extension telephone connected (201). Next, a conversion table showing the correspondence between the generated terminal-specific code and the extension port number is created (202). The extension port number is a unique number provided in each of the extension interface circuits 111 to 114, and is a physical address for controlling the extension telephone. Next, the control data input mode is entered, and the user inputs data required for actual exchange control according to the operation schedule of the extension telephone. The control unit builds an extension control data file by the input data (203). That is, the input data is sorted for each terminal unique code and stored in the storage unit 116 of the main device 100 so that the terminal unique code can be specified and retrieved. Then, the terminal-specific code assigned to each extension telephone is transmitted via the extension interface circuits 111 to 114 (204). On the other hand, on the extension telephone side, for example, the control unit 121 of the extension telephone 101 receives the terminal unique code transmitted from the main device 100 via the data transmission circuit 117 (205) and stores it in the storage unit 122 (206). . Table 1 shows the data files constructed in the storage unit 116 of the main device 100 as described above. In Table 1, various types of extension control data are set for each terminal-specific code. The number j of terminal-specific codes is
This corresponds to the maximum number of extension telephones that can be accommodated in main device 100. The extension control data configured corresponding to one terminal unique code includes various operation information necessary for exchange control such as extension number and extension service class. Table 2 shows a conversion table in which the correspondence between the extension port number indicating the position where the extension telephone is physically connected and the terminal unique code of the telephone itself is recorded. Further, "1" is stored if the extension telephones 101 to 104 are connected to the extension port, and "0" is stored if they are not connected. This indicates the current connection status of the extension telephones 101 to 104. Next, a case where the extension telephone set 101 is detached from the main unit 100 for the purpose of movement will be described with reference to FIG. The control unit 115 of the main device 100 monitors whether or not data transmission with the extension telephones 101 to 104 is possible (210). When the extension telephone 101 is removed from the main device 100 for movement, the extension interface circuit 111 of the main device 100 no longer receives data, and the control unit 115 of the main device 100 detects that the extension telephone 101 is removed. . When detecting that the extension telephone set 101 has been removed, the control unit 115 of the main device 100 rewrites the mounted / unmounted data of the corresponding extension port number in the conversion table from “1” to “0”. That is, the conversion table indicates that no extension telephone is accommodated in the extension port (211). Next, a case where the removed extension telephone set 101 is again connected to another extension port of the main unit 100 will be described with reference to FIG. For example, assume that the extension telephone 101 is connected to another extension interface circuit 112 in FIG. In step 221, the control unit 115 of the main apparatus 100 monitors whether data transmission between the main apparatus 100 and the extension telephones 101 to 104 is possible. When the extension telephone 101 is connected to the extension interface circuit 112 of the main device 100, a data transmission path is formed between the extension interface circuit 112 of the main device 100 and the data transmission circuit 117 of the extension telephone 101, and data transmission is started. (225). When the control unit 115 of the main device 100 detects that the data transmission is started, it recognizes that the extension telephone set 101 is connected, and a terminal-specific code for the extension telephone set 101 via the newly formed data transmission path. A signal for instructing to send, that is, a terminal-specific code request signal is transmitted (222). Upon receiving the terminal unique code request signal (226), the control unit 121 of the extension telephone set 101 reads the terminal unique code from the storage unit 122 (227). Since the backup power supply 123 is connected to the storage unit 122, the terminal unique code is retained even when the extension telephone 101 is removed from the main device 100. The control unit 121 of the extension telephone 101 uses the read terminal-specific code as a data transmission path (extension interface circuit 111 of the main device 100 and data transmission circuit 11 of the extension telephone 101).
7), and the control unit 115 of the main device 100 receives the terminal-specific code sent via the data transmission path (223). At this time, the main device 100 knows the extension port number and the terminal unique code as a pair. Control unit 1 of main device 100
When 15 receives the terminal unique code, the installed / uninstalled data of the corresponding extension port number in the conversion table is rewritten from "0" to "1" to indicate that the extension telephone 101 is accommodated in the extension port. At the same time, the received terminal-specific code is written in the extension port (224). Extension control data based on the terminal-specific code remains set previously, and the control unit 115 of the main device 100 performs exchange control according to the extension control data set for each terminal-specific code. Extension telephone 101 without setting the same as the effect of the invention before removal, the present invention has a plurality of extension interface circuit for connecting to different extension terminals, respectively, to connect a certain extension terminal until now In the key telephone device that can automatically move the control data of the extension terminal even if it is connected to an extension interface circuit different from the extension interface circuit, the control unit of the main device is unique to each extension terminal. In addition to allocating codes, the extension terminal can rewrite the storage part of the terminal unique code, and the terminal allocated by the main unit Since the terminal unique code is stored in this storage unit, and the terminal unique code is stored and held even when not connected to the extension interface circuit, the main device automatically stores the terminal unique code of each extension terminal. All extension terminals will not be assigned a terminal-specific code in each extension terminal, and each extension terminal can be assigned to each extension terminal even if the user or administrator does not manage it so that the terminal-specific code is not duplicated. The terminal-specific code is added without duplication.
