본 발명은 팩시밀리에서의 호출 방법에 관한 것으로, 특히 상대기가 내선에 접속되어 있는 경우 자동호출 전송에 적당하도록 한 팩시밀리의 발신 방법에 관한 것이다.The present invention relates to a method of calling in a facsimile, and more particularly, to a method of sending a facsimile that is suitable for an automatic call transmission when the counterpart is connected to an extension.

제1도는 종래의 팩시밀리 발신회로도로서, 이에 도시한 바와 같이 일반전화선인 선로(1)가 릴레이(2)와 후크오프검출기(3) 및 외부신호에서의 호출음을 검출하는 링검출기(4)에 각각 접속되고, 상기 릴레이(2)와 후크오프검출기(3) 및 링검출기(4)는 입/출력제어부(8)에 각각 접속되며, 한편 릴레이(2)의 타측은 라인트랜스포오머(5) 및 증폭기(6)를 순차로 통해 모뎀(7)에 연결되고, 상기 모뎀(7)과 입/출력제어부(8)는 데이타버스(10)에 의해 시스템제어부(9)에 접속되어 구성된 것으로, 이 종래회로의 동작상태를 설명하면 다음과 같다.FIG. 1 is a conventional facsimile transmission circuit diagram, as shown in FIG. 1, a line 1, which is a general telephone line, to a relay 2, a hook-off detector 3, and a ring detector 4 for detecting a ringing tone from an external signal, respectively. The relay 2, the hook-off detector 3 and the ring detector 4 are connected to the input / output control unit 8, respectively, while the other side of the relay 2 is a line transformer 5 and The amplifier 6 is sequentially connected to the modem 7, and the modem 7 and the input / output control unit 8 are configured to be connected to the system control unit 9 by the data bus 10. The operation state of the circuit is as follows.

송신측에서 상대를 호출하고자 할 경우에는 먼저 입/출력제어부(8)에서 명령을 내려 릴레이(2)를 선로(1)와 연결되게 절체하고, 이에 따라 선로(1)의 신호가 릴레이(2)를 통하고, 라인트랜스(5), 증폭기 (6) 및 모뎀(7)을 순차로 통해 데이타버스(10)에 의해 시스템제어부(9)에 인가되고, 이때 선로전압은 후크오프검출기(3)를 거쳐 입/출력제어부(8)로 인가되어 선로가 전화선로에 연결되었음을 알리게 된다. 이후 릴레이(2)를 절체하여 다이얼신호를 선로(1)에 송출한 뒤 상대에서 후크가 오프되면 응답신호를 검출하여 CCITT 권고한 T,30에 의거 팩시밀리 메세지 전송제어수순 및 메세지 전송등 위상 B.C.D등을 거쳐 선로를 절단하게 된다.When the calling party wants to call the other party, the input / output control unit 8 issues a command to transfer the relay 2 to the line 1 so that the signal of the line 1 is relayed 2. Through the line transformer (5), amplifier (6) and modem (7) in order by the data bus 10 to the system control unit (9), where the line voltage is applied to the hook-off detector (3) Through the input / output control unit 8 is informed that the line is connected to the telephone line. After the relay 2 is switched and the dial signal is sent to the track 1, when the hook is turned off, the response signal is detected and the facsimile message transmission control procedure and message transmission phase BCD, etc. according to the CCITT recommended T, 30 It cuts through the track.

이와 같이 동작되는 기존의 팩시밀리 발신방법에 있어서는 상대기가 구내회선에 접속되어 있는 경우에 자동발호가 불가능하고 반드시 수동발호를 통해서만 메세지를 전송할 수 있는 문제점이 있었다.In the conventional facsimile transmission method operated as described above, there is a problem that automatic call is impossible when the counterpart is connected to the premises line and the message can be transmitted only through manual call.

본 발명은 상기와 같은 종래의 문제점을 개선시키기 위하여, 내선의 호출음을 감지하는 밴드패스필터와 0-9까지의 음성출력을 발생시킬 수 있는 음성발생기를 증폭기의 출력단에 연결시켜 상대기가 내선에 접속되어 있는 경우 자동호출전송하도록 창안한 것으로, 이를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention is connected to the station by connecting a band pass filter for detecting the ring tone of the station and a voice generator capable of generating a voice output of 0-9 to the output terminal of the amplifier to improve the conventional problems as described above. If so, the invention is designed to be automatically called, and this will be described in detail with reference to the accompanying drawings.

제2도는 본 발명에 따른 팩시밀리의 발산회로도로서, 이에 도시된 바와 같이, 선로(1)가 릴레이(2), 후크오프검출기(3) 및 외부선로의 호출음을 검출하는 링검출기(4)에 각각 접속되고, 상기 릴레이(2), 후크오프검출기(3) 및 링검출기(4)는 입/출력제어부(8)에 각각 접속되며, 상기 릴레이(2)의 타측은 라인트랜스포오머(5) 및 증폭기(6)를 순차 거쳐 모뎀(7)에 연결되고, 상기 증폭기(6)의 출력단에는 내선의 호출음을 감지하는 밴드패스필터(11)와 0-9까지의 음성출력을 발생시킬 수 있는 음성발생기(12)를 각각 연결시켜 입/출력제어부(8)에 접속하고, 상기 모뎀(7)과 입/출력제어부(8)는 데이타버스(10)에 의해 시스템제어부(9)에 접속하여 구성한 것으로, 이와 같이 구성된 본 발명의 작용효과를 제3도의 흐름도를 참조하여 상세히 설명하면 다음과 같다.2 is a divergence circuit diagram of the facsimile according to the present invention, and as shown therein, the line 1 is respectively provided to the relay 2, the hook-off detector 3 and the ring detector 4 which detects a ringing sound of an external line. The relay 2, the hook-off detector 3 and the ring detector 4 are connected to the input / output control unit 8, respectively, and the other side of the relay 2 is a line transformer 5 and The amplifier 6 is sequentially connected to the modem 7, and an output terminal of the amplifier 6 has a band pass filter 11 for detecting a ring tone of the station and a voice generator capable of generating a voice output of 0-9. (12) are connected respectively to the input / output control unit 8, and the modem 7 and the input / output control unit 8 are configured by connecting to the system control unit 9 by the data bus 10, If described in detail with reference to the flow chart of Figure 3 the effect of the present invention configured as follows.

일예로 777-8888의 대표전화로 구내 9876번에 팩시밀리가 연결되었다고 가정할 경우 송신측에서 777-8888 스페이스 9876번을 누르면 제3도의 동작 순서도에 따라 상대측이 내선임을 알게 되는데, 먼저 제2도의 릴레이(2)를 절체하여 선로(1)에 접속되게 한 뒤 777-8888의 다이얼을 한다. 그 뒤 응답신호를 감시하여 응답신호(상대편에서 후크오프할 때 발생)를 검지하면, 약간의 지연시간을 두고 음성발생기(12)에서 입/출력제어부(8)를 통해 9876번이 발생하게끔 신호를 준다. 이 9876번 신호는 음성신호로 증폭되어 상대측(777-8888)의 교환수에게 전송된다. 그 뒤 상대측의 내선은 9876으로 결정된다. 이때 다시 내선에서의 호출음을 밴드패스필터(11)를 통해 검출한 뒤 접속이 상대 팩시밀리와 연결되면 상대측과 교신을 시작하게 된다.For example, suppose that the facsimile is connected to 9876 in the premises using the main phone of 777-8888. If the sender presses 777-8888 space 9876, the other party finds the extension according to the operation flowchart of FIG. Transfer the relay (2) to the line (1) and dial 777-8888. After that, when the response signal is detected and the response signal (which occurs when hooking off from the other side) is detected, the voice generator 12 generates the signal 9876 through the input / output control unit 8 with a slight delay time. give. The 9876 signal is amplified into a voice signal and transmitted to the attendant on the opposing side 777-8888. The opponent's extension is then set to 9876. At this time, the ringing tone from the station is detected through the band pass filter 11, and the connection is started when the connection is connected to the partner facsimile.

이상에서와 같이 본 발명에 따른 팩시밀리 발신방법은 팩시밀리가 내선에 접속되어 있는 경우에도 자동발신이 가능함에 따라 사용에 편리함을 도모할 수 있으며, 또한 타이머 통신등에 이용하면 통신로가 싼 심야시간에 설정시켜 놓음에 따라 그 설정시간에 메세지의 전송이 가능하게 되어 팩시밀리 사용료가 절감되는 등의 효과를 갖게 된다.As described above, the facsimile transmission method according to the present invention can facilitate convenient use even when the facsimile is connected to an extension, and can be convenient for use. As a result, the message can be transmitted at the set time, thereby reducing the facsimile fee.
