증설전화 시스템Extension Phone System

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 발명의 주블럭다이어그램도,2 is a main block diagram of the present invention,

제3도는 본 발명의 회로도,3 is a circuit diagram of the present invention,

제5도는 여러 사무실에서 받지 않는 전화를 한 장소에서 받을 수 있는 다회선 증설 전화 시스템.5 is a multi-line extension telephone system that allows calls from one office to be answered at a single location.

Claims (4)

1대의 전화회선에 2대 이상의 전화기를 증설 연결 사용하는 전화에 있어서 주전화기(10)에는 부전화기(제4도와 같이 주전화기(10)를 부장소에서 사용할 경우에는 자신)의 링신호를 임의로 지연(예:링회수5회) 주장소에서 전화를 안받을 경우(예:5회) 부장소 전화기의 링의 울리도록 하는 링지연회로(3)와 자신이 발신하여 외부와 통화중에도 통화가 끊어 지지 않으면서 상대방 전화기의 링거를 동작시켜 링을 울리게 함으로써 상대방 증설 전화기를 호출할 수 있으며, 인터폰 기능을 가능하게 하는 호출회로(2) 및 자신의 통화 내용을 상대방 증설전화기에서 들을 수 없게 하는 비화회로(5), 전화통화를 하는 기능을 가진 전화장치(4)로 구성되는 주전화기(10)와 부장소의 부전화기에도 주장소의 회로장치와 같은 기능을 가진 호출회로(2) 및 비화회로(5), 전화장치(4)로 구성한 증설전화 시스템.In a telephone using two or more telephones connected to one telephone line, the main telephone 10 arbitrarily delays the ring signal of the secondary telephone (if the main telephone 10 is used in the sub-site as shown in FIG. 4). (E.g. 5 rings) If you do not receive a call at the captain (e.g. 5 times), the ring delay circuit (3) to ring the ring of the sub-site phone and The caller's extension phone can be called by operating the ringer of the other party's phone to ring the ringer, and the caller's circuit (2) which enables the interphone function, and the secretion circuit which makes his or her call contents cannot be heard by the caller's extension phone (5). ), A call circuit (2) and a secretion circuit (5) having the same function as the circuit device of the claim station in the main telephone unit (10) consisting of a telephone apparatus (4) having a function of making a telephone call, and a sub-phone in a sub-station. , Phone book Extension phone system is configured to (4). 여러 사무실에서 받지 않은 전화를 한장소에서 받을 수 있는 다회선증설 전화 시스템(제5도)으로 각 사무실에 설치되어 있는 전환기(10)와 각 회선마다 비화회로(5), 호출회로(2)로 구성되어 다국선전화기로 연결된 주장치(50)로 구성된 다회선 증설 전화 시스템.It is a multi-line extension telephone system (figure 5) that can receive calls not received in various offices in one place. It is provided with a switch 10 installed in each office, a secret circuit (5), and a call circuit (2) for each line. Multi-line telephone extension system consisting of a main unit (50) configured to be connected to a multi-line telephone. 제1항 또는 제2항에 있어서 극선 발신하여 외부와 통화중에도 통화가 끊어지지 않으면서 상대방 전화기의 링거를 동작시켜 링을 울리게 하는 호출 회로(2) 즉, 제3도의 호출회로(2)와 같이 저항(R2)과 푸쉬 보턴 스위치(RS1)로 구성 되어 호출하기 위하여 푸쉬 보턴 스위치(RS1)를 눌렀을 때도 전화기의 루프 전류는 저항(R2)을 통하여 훅크스위치(HS1)를 거쳐서 통화회로, L2로 흐르므로 국선 발신하여 외부와 통화중에도 통화가 끊어지지 않으면서 상대방 전화기의 링거를 동작시키는 회로와 브릿지다이오드(BD1), 발광다이오드(LD1), 저항(R1)으로 구성되어 상대를 호출할때 L1, L2의 전위방향에 관계없이 항상 발광 다이오드에 불이 들어와 호출상태의 정상 유무를 알 수 있는 호출상태 표시회로.The call circuit (2) according to claim 1 or 2, wherein the call circuit (2) of FIG. resistor (R2) and when the loop current of the telephone pressing a push boteon switch (RS1) to push boteon switch to call consists of (RS1) is via the hook switch (HS1) via the resistor (R2) to the call circuit, L 2 As it flows through the CO line, it is composed of a circuit which operates the ringer of the other party's phone without disconnecting the call even when talking with the outside, bridge diode (BD1), light emitting diode (LD1), and resistor (R1). Call state display circuit that can know whether call state is normal because LED is always on regardless of potential direction of L2. 제1항 또는 제2항에 있어서 콘덴서(C2)를 통하여 브릿지다이오드(BD1)로 연결된 정류회로와 발광다이오드(LD2)와 저항(R3)이 병렬로 연결된 링회로 동작상태 표시회로 및 콘덴서(C4-C10)와 스위치(DS1-DS7), 훅크스위치(HS2), 저항(R4), 가변저항(VR1-VR2), 다이오드(D1), 릴레이(RY)로 구성된 링지연 설정회로 그리고 콘덴서(C1)릴레이 스위치 연결하여 링신호를 임의로 지연시킬수 있는 링지연회로(3).The display circuit and the condenser C4- of claim 1 or 2, wherein the rectifier circuit connected to the bridge diode BD1 through the capacitor C2 and the ring circuit operation state in which the light emitting diode LD2 and the resistor R3 are connected in parallel. C10), ring delay setting circuit consisting of switch (DS1-DS7), hook switch (HS2), resistor (R4), variable resistor (VR1-VR2), diode (D1), relay (RY), and capacitor (C1) relay Ring delay circuit (3) capable of arbitrarily delaying the ring signal by connecting a switch. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
