Abstract

PURPOSE:To eliminate the need for storing plural telephone numbers and opposite names for an opposite party to identify the opposite party depending on the telephone number by providing a name memory, reading an area of a name corresponding to a caller telephone number and displaying the result onto the display device of a key telephone set. CONSTITUTION:A master set 1 and a key telephone set 2 having a display device are provided, and the master set 1 is provided with a key telephone set interface 12 interfacing the key telephone set 2, a line interface 17 accommodating an S/T point interface of an ISDN line, a RAM 15 storing required information to control the entire master set 1, a name memory 16 storing a name corresponding to a telephone number, and a central control section (CPU) 4 controlling the entire master set 1. Then when a call comes from an ISDN line, the name is displayed on the display device of the key telephone set. Thus, the caller is more clarified.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to electronic key telephone devices.

[Conventional technology]

Conventional electronic key telephone devices contain ISD
[Problem to be Solved by the Invention] The above-mentioned conventional electronic button telephone device is designed to display the telephone number of the calling party when a call is received from the N line. When a call is received from the line, the telephone number of the caller is displayed, so the person answering the call must memorize multiple telephone numbers and the name of the other party in order to identify the other party by the telephone number. The disadvantage is that you have to keep it.

[Means to solve the problem]

The electronic button telephone device of the present invention is an ISDN S/T
In the electronic key telephone device, the main device includes a main device that is provided with a point interface and houses a key telephone that has a display, the main device having a storage unit that can store at least one telephone number as well as a name corresponding to the telephone number. When a call is received on the ISDN line accommodated in the main device, the caller's telephone number included in the call setting information sent from the ISDN line and stored in the storage unit. reading means for sequentially comparing the telephone numbers and, if they match, reading out a name area corresponding to the calling party's telephone number from the storage section, and reading data in the name area read by the reading means; and control means for controlling the display to be displayed on the display of the key telephone.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Fig. 1 is a block diagram showing one embodiment of the present invention, Fig. 2 is a diagram showing an example of the ellipse of the name memory in Fig. 1, and Fig. 3 is a block diagram showing an example of the name memory in Fig. 1. 2 is a flowchart showing an example of the processing of the central control unit when In FIG. 1, the button telephone device of this embodiment is a main device 1.
and a button telephone 2 having a display (not shown), and the main device 1 includes a button telephone interface 12 that interfaces with the button telephone 2, and an S of the ISDN line.
/Line interface 1 that accommodates the T point interface
7, a RAM 15 that stores information necessary to control the entire main device 1, a name memory 16 that stores names corresponding to telephone numbers, and a central control unit that controls the entire main device 1 ( (hereinafter referred to as CPU) 14.

It is assumed that when the button telephone receives the ASCII code as display data from the main device 1, it displays it on the display. FIG. 2 shows an example of the contents of the name memory 16. The RAM 15 is divided into m blocks, and each block stores a telephone number and a name corresponding to the telephone number in ASCII code.

Next, the operation of this embodiment will be explained using FIGS. 1, 2, and 3.

When there is an incoming call on the T SDN line, the information is notified to the CPU 14 via the line interface 17, and the CPU 14 starts processing the flow shown in FIG. 3 (Part 1) (Part 2). First, the "call setting" information sent from the ISDN line is analyzed (S31), and the presence or absence of the calling number is confirmed (S32). If there is no calling number,
Processing ends because it is unknown who is the calling party. If there is a calling number, extract the calling number A from "Call settings" (333)
. Next, the initial value 1 is set to the variable k used for reading from the name memory 16 (S34). Then, the number m of blocks in the name memory 16 is compared with the variable k (S35).

If the variable k is larger than m, this indicates that reading from the name memory 16 has been completed, and the process is terminated. If the variable k is smaller than m, the telephone number in block k of the name memory 16 is read (S37), and the read telephone number is compared with the calling number A (S38). if,
If they are not equal, 1 is added to the variable k in order to read the next memory block (S36) and the process 35 is performed again. If they are equal, the ASCII data in memory block k is read (S39). Next, it is checked whether there is a key telephone that displays an incoming call (S40). If it exists, the ASCII data read out as display data is sent to the key telephone (S41) and the process ends.

If there is no button telephone, the process ends.

Through the above processing, it becomes possible to display the name of the caller on the display of the key telephone according to the calling number sent from the line when a call is received on the ISDN line.

〔Effect of the invention〕

As explained above, the present invention has a storage section that can store at least one telephone number and a name corresponding to the telephone number in the main device accommodating the ISDN line, and when an incoming call is received on the ISDN line accommodated. If a caller's telephone number is found in the call setting information sent from the ISDN line and the telephone number stored in the storage unit is compared sequentially, and if they match, the caller's telephone number is sent from the storage unit. By having a reading means for reading out the name area corresponding to the telephone number of the I
When a call is received on the N line, the name rather than the phone number is displayed on the display of the button telephone, making it clearer who the caller is, and by registering only particularly important parties in the memory. If you receive a call from an important person, the name will be displayed, and if it is not, it will not be displayed.
