모니터부의 입력을 받아들여 시간모드이면 전화번호 버튼에 의해 예약시간을 설정하고 입력모드에서는 상대방 전화번호를 입력한 다음 시간을 계수하여 사용자가 예약한 시간이 되면 상대방 전화에 대한 다이얼 신호를 송출하고 상대방이 통화중일 때에는 화중음을 검출하여 전화루프를 끊어서 전체 시스템이 정지 상태로 들어가게한 다음 이후 소정시간간격으로 전호를 다시 걸어서 상대의 전화상태를 조사하는 과정을 소정횟수 반복실시하며 상대방이 전화를 받지 않아서 링백론 신호가 일정시간동안 계속될 때에는 전화루프를 끊어서 시스템이 대기상태에 들어가게함과 아울러 소정시간 간격으로 상대방 전화를 다시 호출하는 과정을 소정횟수 반복실시하며 상대방이 일정시간 내에 전화를 받으면 저장된 디지탈 데이타를 합성하여 사용자에게 전화통화를 하도록 메세지를 출력함과 아울러 사용자가 송, 수화기를 들때까지 상대방에게 기다리도록 음성신호를 송출하도록 동작하는 것을 특징으로 하는 예약전화방식.In case of time mode, it sets the reservation time by telephone number button in input mode of monitor unit, and inputs the other party's phone number in input mode, counts the time, and sends the dial signal for the other party's phone when the user's time is reserved. During this call, the system detects a busy tone, breaks the telephone loop, and enters the entire system into a stopped state. Afterwards, the telephone line is re-examined at a predetermined time interval to repeat the process of checking the other party's telephone state. If the ringbackon signal continues for a certain period of time, the system will enter the standby state by disconnecting the telephone loop and repeat the process of re-calling the other party's phone at a predetermined time interval. Synthesize digital data to the user It outputs a message to a phone call as well as reserved telephone system characterized in that the operation a user to transmit the audio signal to wait for the other party to the transmission deulttae, receiver. 전화라인(Tip, Ring)에 전화루프를 단속하는 라인 스위칭부(10)와 다이얼톤을 검출하는 다이얼톤 검출부(20)와, 화중음을 검출하는 화중음 검출부(30)와, 링백톤 신호를 검출하는 링백톤 검출부(40)와, 특정 주파수성분을 검출하는 필터부(50)와, 전화기의 사용유무에 따라 개방 또는 단락되는 후크 스위치(HS1)와 다이얼 신호를 제어하는 다이얼 제어부(60)와, 음성신호 저장부(90)에 디지탈 형태로 저장된 음성데이타를 시스템 제어부(120)의 제어에 따라 합성하여 음성신호를 발생하는 음성신호제어부(70)와, 상기 음성신호를 일정레벨로 증폭하여 출력하는 음성신호 출력부(80)와, 송, 수화음의 크기를 제어하는 송, 수화부(100)와, 예약시간 및 전화번호를 설정하는 모니터부(110)로 구성된 것을 특징으로 하는 예약전화기회로.Line switching unit 10 for intercepting the telephone loop to the telephone line (Tip, Ring), dial tone detection unit 20 for detecting the dial tone, call tone detection unit 30 for detecting the ring tone and ring back tone signal A ringback tone detection unit 40 for detecting, a filter unit 50 for detecting a specific frequency component, a hook switch HS1 for opening or shorting according to the use of a telephone, a dial control unit 60 for controlling a dial signal, and The voice signal controller 70 generates a voice signal by synthesizing the voice data stored in the digital form in the voice signal storage unit 90 under the control of the system controller 120, and amplifies and outputs the voice signal to a predetermined level. Reservation telephone circuit comprising: a voice signal output unit 80, a song and receiver unit 100 for controlling the volume of a song and a sign language, and a monitor unit 110 for setting a reservation time and a telephone number . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
