Abstract

The present invention relates to an automatic answering method of a simple electronic switching system, and at present, since communication is performed using a trunk line, various kinds of information cannot be transmitted and appropriate calls cannot be made depending on the situation of the receiver. The present invention is a first step of receiving a call signal from the other side exchange, in order to solve such a conventional problem, receives the information of the other side and transmits it to the called subscribers; Invented an automatic response method of a simple electronic exchange consisting of a second step in which the receiver confirming the information of the first step performs an automatic response operation according to a selected function according to a situation. In a simple electronic exchange, information such as a caller ID and an originating exchange ID can be checked using the D channel and the B channel, and the called party can automatically select an appropriate call according to the situation.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple electronic exchange, and more particularly, to an automatic response method of a simple electronic exchange which enables automatic caller identification and response processing in two simple electronic exchanges connected to a private ISDN.

ISDN (Integrate Service Digital Network) is a means for telephony, telegraph, and other non-systemic services that are coexisting with each other, and is based on digital technology. A communication network that provides telecommunication services.

However, at present, since communication is performed using the CO line, various information cannot be transmitted and appropriate calls cannot be made depending on the situation of the receiver.

FIG. 1 is a block diagram of a general simple electronic exchanger. As shown in FIG. 1, a simple electronic exchange system is generally composed of a key phone 110, 210, a general telephone 120, 220, and a simple electronic exchange 100, 200. When the exchanges 100 and 200 are connected to the private ISDN 300, the communication means that are currently being operated separately, such as public telephone networks, telex networks, and facsimile networks, meet requirements according to the user's (ie, subscriber's) change or opportunity. However, it is possible to configure a network system that enables communication or information processing anytime, anywhere cheaper, more convenient and sure.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic response method of a simple electronic exchange which enables automatic confirmation and response processing of a sender by using a B channel and a D channel in a simple electronic exchange connected by a private ISDN.

The automatic answering method of the simple electronic switch for achieving the object of the present invention comprises the steps of: receiving a call signal from the exchange, receiving the information of the other party and delivering it to the called subscriber; A second step is performed by the receiver, which has confirmed the information of the first step, to perform an automatic response operation according to a function selected according to the situation.

Hereinafter, the operation and effects of the present invention will be described in detail with reference to FIG. 1 which shows a general block diagram of a simple electronic exchanger and FIG. 2 which shows an automatic response operation flow of the present invention.

First, its simple exchanger will be referred to as a 'local exchanger' 100, and the other party's simple exchanger will be referred to as a 'remote exchanger' 200. In two simple exchanges (100, 200) connected to the private ISDN (300), when a call setup request, i.e., a call, comes from the exchange on the other side, the local exchange (100) allocates a B channel, and through the D channel, the caller's ID, Check the ID and function selection information of originating exchange. (ST1-ST3)

In addition, the ring signal is applied to the called subscriber's key phone telephone 110 and the displayed information is displayed on the display unit of the key phone switcher 110. (ST4, ST5)

As a result, the called party identifies the caller and selects various pre-programmed functions according to the situation of the called party and makes an appropriate call.

For example, if you need to receive a message from the other side but cannot communicate, select the feature to reply by voicemail.

Accordingly, the local exchange 100 transmits a message to the other party to leave a message in the voice mail, and then records it when the voice message is transmitted from the other party. (ST6, ST7)

But please try again later. Or I'll call you later. If you want to send a simple message such as a preset, select the message transmission function that stores the desired message content.

Accordingly, the local exchange 100 transmits a predetermined message selected to the caller. (ST8, ST9) Of course, the local exchange 100 may directly call the caller without selecting the above function. (ST10)

When the call with the caller is terminated through the above operation, a release request signal is input through the D channel. Then, the call ends normally. (ST11, ST12)

As described in detail above, the present invention can confirm information such as a caller ID and an ID of an outgoing exchange using a D channel and a B channel in a simple electronic exchange connected to a private ISDN, and the recipient of the confirmed information is automatically appropriate according to the situation. It has the effect of selecting a currency.

Claims (4)

A first step of receiving a call signal from the exchange and receiving information of the other party and delivering the information to the called subscriber; And a second step of performing the auto-response operation according to the function selected by the receiver, which has confirmed the information of the first step, in accordance with a situation. 2. The automatic answering method of a simple electronic exchange as claimed in claim 1, wherein the information of the other party is a caller ID and an ID of the other party exchange. The automatic answering method of a simple electronic exchange as claimed in claim 1, wherein the automatic answering operation records the other party's message through the response mail. The method of claim 1, wherein the automatic response operation transmits a predetermined message to the counterpart.
