Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

예약서비스를 제공하는 사설교환기에 연결된 팩시밀리의 자동 비지 재다이알 회로 및 방법에 관한 것이다.An automatic busy redial circuit and method of a facsimile connected to a private exchange providing a reservation service.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

국선비지 해제시점을 감지하여 국선비지가 해제되자마자 재송신을 개시하여 불필요한 송신지연을 없앤 자동비지 재다이알 회로 및 방법을 제공한다.The present invention provides an automatic busy redial circuit and a method for detecting a time when the trunk line busy is released and starting retransmission as soon as the trunk line busy is released, thereby eliminating unnecessary transmission delays.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

예약서비스를 제공하는 사설교환기에 연결된 팩시밀리의 자동 비지 재다이알방법에 있어서, 자동 다이알 기능키의 입력을 감지하면 국선을 점유하기 위해 상기 사설교환기에 국선액세스코드를 송출하는 제1과정과, 상기 국선액세스코드의 송출후 국선으로부터 송출되는 톤을 검출하는 제2과정과, 상기 제2과정에서 비지톤이 검출되면 국선비지상태로 판단하고 상기 사설교환기로 국선예약코드를 송출한 후 라인을 끊는 제3과정과, 상기 사설교환기로부터 국선사용가능을 알리는 링신호가 수신되는지 여부를 체크하는 제4과정과, 상기 사설교환기로부터 국선사용가능을 알리는 링신호가 수신되면 국선으로부터 입력되는 톤을 검출하고 그 검출된 톤에 따라 팩스를 송신 혹은 수신하는 제5과정으로 이루어짐을 특징으로 한다.A method of automatic busy redialing a fax connected to a private exchange providing a reservation service, the method comprising: a first process of sending a COS access code to the private exchange to occupy a trunk line when sensing an automatic dial function key input; A second process of detecting a tone transmitted from a CO line after the transmission of an access code; and a third process of determining that a busy tone is detected in the second process and disconnecting a line after transmitting a CO line reservation code to the private exchange. And a fourth step of checking whether or not a ring signal indicating that trunk line is available is received from the private exchange, and detecting a tone input from the trunk line when receiving a ring signal indicating that trunk line is available from the private exchange. And a fifth process of transmitting or receiving a fax according to the received tone.

4. 발명의 중요한 용도4. Important uses of the invention

팩시밀리가 연결된 사설교환기에서 국선을 점유하기 위해 국선으로 스위칭할 때 국선비지인 경우 상기 팩시밀리가 자동으로 국선예약서비스를 대행하여 국선비지가 해제되는 순간을 감지하자마다 재다이알링을 수행하므로 송신지연시간을 줄이는 데에 사용한다.Transmit delay time when the facsimile detects the moment when the facsimile is cleared by the facsimile automatically when the facsimile is busy when switching to the trunk line to occupy the trunk line at the private exchange connected to the facsimile.

Description

Automatic Busy Redial Circuit and Method of Facsimile

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명이 적용되는 팩시밀리의 구성도.2 is a block diagram of a facsimile to which the present invention is applied.

Claims

A facsimile machine capable of receiving a CO line reservation service from a private exchange, comprising: memory means for storing information on an automatic dial function key, tone detection means for detecting busy tone, dial tone, etc. sent from a CO line, and the detected tone Control means for determining whether the trunk line is busy or not, and overall control for the automatic busy redial, and when the trunk line busy state is detected, the trunk line for generating the trunk line reservation signal under the control of the control means. 2. A facsimile automatic busy redial circuit comprising a reservation signal generating means and dialing means for generating a dial signal for automatic redialing under the control of the control means.

2. The facsimile automatic busy redial circuit of claim 1, further comprising a first timer means for transmitting to the control means whether a preset time interval or a redial interval set by a user has ended.

The second timer means according to any one of claims 1 and 2, wherein the second timer means checks the waiting time when the other party is not busy but no CD tone is detected and transmits the elapsed time to the control means. Further comprising: a facsimile automatic busy redial circuit.

A method of automatic busy dialing of a facsimile connected to a private exchange providing a trunk line reservation service, the method comprising: a first process of sending a trunk line access code to the private exchange to occupy a trunk line when the automatic dial function key is detected; A second step of detecting a tone transmitted from the CO line after the CO line access code is sent; and if a busy tone is detected in the second step, determining that the CO line is busy and sending the reservation line code to the private exchange and cutting off the line. And a fourth step of checking whether or not a ring signal indicating the availability of a trunk line is received from the private exchange, and detecting a tone input from the trunk line when receiving a ring signal indicating that trunk line use is available from the private exchange. And a fifth step of transmitting or receiving a fax according to the detected tone.
