The present invention for achieving the above object is a local telephone exchange device, a key input unit for receiving the identification information of the extension subscriber from the telephone user, memory means for storing the telephone number assigned to correspond to the identification information and The call signal transmitted from the premises telephone and the premises telephone including a microcomputer for transmitting a call signal corresponding to the retrieved premises telephone number by searching the premises telephone number corresponding to the identification information input through the key input unit in the memory means; According to the characterized in that it comprises a premises exchange to perform the exchange connection with the corresponding telephone.

Hereinafter, with reference to the drawings the preferred embodiment of the present invention will be described in detail.

1 is a schematic diagram of an extension telephone switchboard according to the present invention. As shown in FIG. 1, between a first premises telephone 10 installed in a premises, a plurality of second premises telephones 30 and a first premises telephone 10 and a second premises telephone 30 installed elsewhere in the premises. It consists of a premises exchange 20 to perform the exchange connection.

2 is a block diagram of the extension telephone of FIG. As shown in Figure 2, the extension telephone according to the present invention is a number key having a numeric key key arrangement, a letter key (Korean and English input) for inputting identification information (for example, name) of the extension subscribers Key input unit 110 for generating a signal according to a key operation, a signal processing for voice call, and a call circuit 120 for detecting a hook state. And a line interface unit 130 for interfacing the transceiving voice signals of the call circuit 120 to the transit switch 20.

In addition, the extension telephone is a memory unit 140, which stores the subscriber subscriber's identification information such as identification information and extension telephone number, the display control unit 150, a display control unit 150 for outputting a signal for displaying the display information Search for the extension telephone number corresponding to the identification information in the memory unit 140 according to the identification information of the extension subscriber inputted from the display unit 160 and the key input unit 110 by displaying the extension information of the subscriber by the output signal of the And, it displays a searched premises telephone number, and includes a microcomputer (100) for controlling the operation of transmitting a call signal corresponding to the displayed premises telephone number.

3 is a flowchart illustrating an extension telephone exchange device according to the present invention. As shown in FIG. 3, the microcomputer 100 checks the key input of the key input unit 110 to determine whether an extension telephone number search key is input from the telephone user (S100). As a result of the determination, if there is an input of a search key, the microcomputer 100 displays the display unit 160 through the display controller 150 to input identification information of the extension subscriber to be searched by the telephone user, and inputs identification information from the telephone user. Check (S110). At this time, the telephone user inputs the name of the extension subscriber to be called through the character key of the key input unit 110 or enters the employee number through the numeric key.

When the identification result identification information is input in step S110, the microcomputer 100 is the extension telephone number corresponding to the identification information in the memory unit 140 stored in the extension telephone number pre-allocated corresponding to the identification information of the extension subscriber. Search for (S120). The microcomputer 100 displays the searched extension telephone number on the display unit 160 (S130).

Thereafter, the microcomputer 100 determines whether there is an input of a call key for making a call command to make a call with the extension telephone of the extension telephone number displayed on the display unit 160 (S140). As a result of the determination, if there is an input of the call key, the microcomputer 100 corresponds to the premises exchanger 20 through the line interface unit 130 so that the premises exchanger 20 can talk to the premises telephone corresponding to the premises telephone number.
