Abstract

PURPOSE:To secure mutual contact between extensions by storing a selt-extension number in a memory when an opponent extension does not execute a response, displaying the self-extension number in the opponent extension and when an opponent dials a special number, executing a display in the LCD display part of a called extension. CONSTITUTION:When an extension 1 is absent and no-response is obtained, an extension 2 dials the first special number. When a central control device 5 receives the first special number, a dial information accumulation displaying memory 6 is admitted. The calling extension 2 and an incoming time are stored in a the correspondent storing area of the called extension 1. At such a time, the extension number of the extension 2 is still displayed on the LCD display part of the extension 1. The called person of the extension 1 comes back and observes the LCD display. Then, the called person can know that there is an incoming during an absent time. When the called person dials the second special number, the central control device 5 removes information, which are stored in the dial information accumulating memory 6, and displays the incoming time and the opponent extension number on the LCD display of the extension 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is an automatic telephone exchange that stores the calling party's number, etc. when the called party is absent.

This relates to a method for displaying the calling party's number, etc. on the telephone when the called party returns and performs a specific operation.

(Prior Art) Conventionally, as a method of leaving the calling party's number on the called party's telephone, there has been a method of displaying it as it is on the called party's LCD display screen without using a memo 17k.

(Problem to be solved by the invention) However, in the conventional system, what is displayed on the LED display is the last calling number, and the calling number information received before that is erased. , had the disadvantage that it was impossible to know.

The purpose of the present invention is to solve the above-mentioned drawbacks, and to solve the above-mentioned drawbacks. The object of the present invention is to provide a calling party number storage and display method that can notify the called party.

(Means for Solving the Problems) In order to achieve the above object, the calling party number storage display method according to the present invention is a method for storing and displaying a calling party number for a called party in an extension interconnection system of an electronic private branch exchange. When the first special number is stored in memory and is dialed by the calling party when the called party is absent, the first special number is received.

Memorize the calling number and the time of arrival.

When the called party dials and receives the special number 2g2, it reads out all the calling party number and its arrival time stored in the memory and displays it on the LC of the called party's telephone.
It is configured to be displayed on the D display section.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a relay system diagram of an electronic switching system of storage and display type, showing an embodiment of the calling party number storage and display system according to the present invention.

In FIG. 1, when extension 1 is away from his/her seat, extension 2 will call extension 1. The side tone will be explained below.

The central control device 5 analyzes all the selection signals, controls all of the one communication path 4, and connects it to the ringer transmission source RGT2 (not shown), extension line 1.

A ringback tone source RBTi is connected to extension 2.

Here, since extension 1 is not available, there is no response.

If you want extension 2 to call you when extension 1 returns, use the first special number. Dial. Connected to the central control device 5 is a dial information storage and display memory 6 that can store information corresponding to each extension.

FIG. 2 is a diagram showing an example of the configuration of a dial information storage display memory.

The memory has storage areas (1) to (n) for each extension.
', and each storage area can store the incoming extension number and incoming time of (1) to (F).

When the central control unit 5 receives the first special number via the calling register OGT', it analyzes the content and stores it in the dial information storage and display memory 6.

Then, the calling extension 2 and its call arrival time are stored in the corresponding storage area of the called extension 1. At this time, the extension number of extension 2 remains displayed on the LCD display section of extension 1.

Similarly, if you make a call to extension 3 or extension 1, and after hearing the ringback tone, dial the first special number, the extension number of extension 3 and the current time will be stored in which area in the dial information storage display memory 6. is stored in the next memory. At this time, the previous display on the LCD display section for extension 1 is erased and the extension number for extension 3 is displayed.

Thereafter, by repeating the above operations, up to M pieces of information are successively written into the dial information storage and display memory. The display also shows the last caller's extension number.

Later, when the called party on extension 1 returns and fully recognizes that the extension number is displayed on the LCD display screen, he or she will know that a call has been received while the callee was absent.

When the called party completes the second special number, the central control unit 5 retrieves the last 10,000 pieces of information stored in the dial information storage memory 6 and displays the time and date of the incoming call on the LCD display screen of extension L. Display the other party's extension number.

After that, by repeating the hooking operation, the information is sequentially retrieved from the dial information storage display memory, and the other party's extension number is displayed. You can know everything.

The contents of the dial information storage display memory 6 are set to L by hooking.
Cleared when CD display is performed.

(Effects of the Invention) As explained above, in the present invention, when the other party's extension is not answered, one's own extension number is stored in the memory, one's own extension number is displayed on the other party's extension, and when the other party dials all special numbers, Since the stored contents are illuminated and displayed on the LCD display section of the called extension, there is an effect of ensuring mutual communication between the extensions.

Claims (1)

[Claims] In the extension interconnection system of an electronic private branch exchange, a calling party number storage display memory is provided for the called party, and when the calling party receives the first special number to be dialed when the called party is absent, the above-mentioned call When the called party dials and a second special number is sent, the calling party number and the time of arrival are all read out from the memory and the called party A caller number storage display method characterized by displaying the caller number on the LCD display section of the caller's telephone.
