Abstract

The device controls a calling function for the facsimile by discriminating and selectively processing the signals respectively. The method comprises the steps of: detecting the facsimile transmission signal to receive the data when ring signal is detected; connecting the telephone line by generating the ring signal when the facsimile signal is not transmitted for a time interval; and connecting the line to the place of the DTMF tone designated.

본 발명은 팩시밀리를 통한 전화호출 제어에 관한 것으로, 특히 전화회선으로 수신된 신호를 판별하여 팩스 신호와 전화신호를 선별적으로 처리할 수 있도록 한 팩시밀리의 전화호출 기능 제어방법에 관한 것이다.The present invention relates to a telephone call control through a facsimile, and more particularly, to a method for controlling a facsimile's telephone call function to discriminate a signal received through a telephone line and to selectively process a fax signal and a telephone signal.

제1도는 본 발명과 관련된 하드웨어의 구성도로서 이에 도시한 바와 같이, 일반 전화회선을 제어하는 전환회선 제어부(1)와, 링 신호를 발생시키는 링신호 발생부(3)와, 팩시밀리 시스템(2)으로 구성된다.1 is a configuration diagram of hardware related to the present invention, as shown therein, a switching line control unit 1 for controlling a general telephone line, a ring signal generation unit 3 for generating a ring signal, and a facsimile system 2 It is composed of

제2도는 본 발명에 따른 팩시밀리를 이용한 저화수신 방법의 제어 흐름도로서 그 직용과 효과를 상세히 설명하면 다음과 같다.2 is a control flowchart of a method of lowering reception using a facsimile according to the present invention.

먼저, 전화회선으로부터 링신호가 인가되면 전화회선을 일단 팩스측으로 절제한 후 6초이내에 팩스신호가 검출되는지 팩스 시스템에서 판단하여 팩스 신호(CNG)가 검출되면 팩스를 수신하고 6초가 경과하도록 팩스신호가 검출되지 않으면 기지정된 곳, 즉 팩스에 연결된 전화기의 후크-오프(hook-off)를 검출한다.First, when a ring signal is applied from the telephone line, the fax system determines whether the fax signal is detected within 6 seconds after cutting off the telephone line to the fax side. When the fax signal is detected, the fax signal is received after 6 seconds. If is not detected, it detects the hook-off of the predetermined place, i.e., the telephone connected to the fax.

만일 후크-오프가 검출되면 전화회선을 연결된 전화기쪽으로 연결해줌으로써 통화가 가능하도록 하면 이후 후크-온이 되는가를 모니터링하여 후크-온이 되면 라인을 절제한다.If a hook-off is detected, the telephone line is connected to the connected telephone to enable the call, and then the hook-on is monitored by monitoring whether the hook-on is made.

또한 일정 시간동안 링을 송출하여도 후크-오프가 검출되지 않는 경우에는 라인을 절제한다.If the hook-off is not detected even after the ring is sent for a certain time, the line is cut off.

한편, 팩스 신호를 검출한 후 전화회선을 연결할 곳이 기지정되어 있지 않은 경우에는 정해진 DTMF(Dual Tone Muli Frequency) 톤 신호가 검출되는지를 확인하여 외부에서 DTMF로 링신호를 송출하여 원하는 곳을 호출할 수 있는데, 예로서 DTMF 톤 “#”와 “1”, “2”, “3”키를 지정해놓고 “#”+“1”키에 해당되는 톤이 범출되면 그에 대응하는 곳을 호출하는 방식으로 할 수 있다.On the other hand, if there is no known place to connect the telephone line after detecting the fax signal, check whether the specified DTMF (Dual Tone Muli Frequency) tone signal is detected and send ring signal to DTMF from outside to call the desired place. For example, the DTMF tones “#” and “1”, “2”, and “3” keys can be assigned, and the corresponding tone will be called when the tone corresponding to the “#” + “1” keys is released. You can do

팩스 신호의 검출후 전화연결을 위한 지정된 곳이 없고 정해진 DTMF 톤도 검출이 안되는 경우 팩스 본체에 연결된 핸드 세트(hand set)의 후크-오프를 일정 시간 감지한 후 후크-오프가 검출되면 라인을 핸드 세트쪽으로 연결하여 통화가 가능하게 한다.After detecting the fax signal, if there is no designated place for the telephone connection and the specified DTMF tone cannot be detected, the hook-off is detected for a certain time after the hook-off of the hand set connected to the fax machine is detected. Connect to the set to make a call.

따라서 하나의 전화회선에 본 발명의 기능을 갖고 있는 팩시밀리을 연결함으로써 외부에 여러개의 전화기를 연결하여 사용할 수 있어 사무실에 구분되어 있는 조직에서 하나의 전화회선을 효율적으로 사용할 수 있게 된다.Therefore, by connecting a facsimile having the function of the present invention to one telephone line, it is possible to connect several telephones to the outside, so that one telephone line can be efficiently used in an organization divided in an office.

이상에서와 같이 본 발명은 팩시밀리에 전화호출기능을 부여하는 효과를 준다.As described above, the present invention gives the facsimile the telephone call function.

Claims (1)

링신호가 검출되면 전화회선을 팩스로 절체한 다음 팩스 송신신호를 검출하여 팩스를 수신하는 단계와, 소정 시간동안 팩스 신호가 송신되지 않으면 기지정된 곳으로 링신호를 송출하여 전화회선이 연결되게 하는 단계와, 전화회선을 연결할 곳이 기지정되어 있지 않으면 디티엠에프 톤에 의해 지정된 곳으로 전화회선을 연결시켜 소정 시간동안 통화가 이루어지게 하는 단계를 포함하는 것을 특징으로 하는 팩시밀리의 전화호출 기능 제어방법.When a ring signal is detected, the telephone line is switched to a fax, and then a fax transmission signal is detected to receive a fax. If the fax signal is not transmitted for a predetermined time, a ring signal is sent to a predetermined place so that the telephone line is connected. And if the place where the telephone line is to be connected is not determined, connecting the telephone line to a place designated by DFM tone and making a call for a predetermined time. Way.
