Description

부속전화기의 제어접속장치Control connection device of attached telephone

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

제1도는 본 발명에 따른 부속전화기의 제어접속장치 구성도.1 is a block diagram of a control connection device of the accessory telephone according to the present invention.

Claims (1)

제어시스템과 데이타포트(P)를 통해 통신하며, 롬(11)및 램(10)을 제어하여 시스템제어를 하는 마이컴(9)과, 전화기접속부(7)를 통한 부속전화기와의 통신신호를 완충시키는 완충기(5)와, 국선접속부(1)를 통한 국선(L1,L2)과의 통신신호를 메칭시키는 정합부(2)와, 그 정합부(2)와 상기 완충기(5)와의 통화로를 스위칭시키는 통화로스위치(3),(4)와, 사이 정합부(2)와 상기 통화로스위치(3)사이에서 검출되는넘버링 신호가 제어용 비밀번호인지를 확인하는 비밀번호확인회로(18)와, 상기 정합부(2)를 통해 멜로디음을 송출하기 위한 멜로디발생기(16)와, 상기 롬(11)의 출력을 음성신호로 합성시키는 음성합성부(12)와, 상기 통화로스위치(3), (4)사이에서 검출되는 신호를 증폭하여 상기 마이컴(9)에 인가하는 수신앰프(8)와, 그 마이컴(9)의 출력 및 상기 음성합성부(12)의 출력을 증폭하여 상기 통화로스위치(3), (4)사이에 연결하는 송신앰프(15)와, 상기 국선(L1,L2)으로부터 링신호를 검출하는 링검출기(13)와, 상기 비밀번호확인회로(18)및 상기 완충기(5)의 출력을 상기 마이컴(9)에 전달함과 아울러 그 마이컴(9)의 제어신호를 상기 통화로스위치(3),(4), 상기 멜로디발생기(16) 및 상기 국선접속부(1)의 통화스위치(S1)에 전달하는 멀티플렉서(14)로 구성하여 된 것을 특징으로 하는 부속전화기의 제어접속장치.It communicates with the control system via the data port (P), buffers the communication signal with the microcomputer 9 for controlling the ROM 11 and the RAM 10 and the accessory telephone via the telephone connection unit 7. And a matching path (2) for matching a communication signal with the trunk lines (L1, L2) through the trunk line connecting portion (1), the matching part (2) and the buffer path (5). A password confirmation circuit 18 for confirming whether the numbering signal detected between the communication path switches 3 and 4 to be switched between the matching unit 2 and the communication path switch 3 is a password for control, and A melody generator 16 for transmitting the melody sound through the matching unit 2, a voice synthesizer 12 for synthesizing the output of the ROM 11 into a voice signal, and the communication path switch 3, ( 4) amplifying a signal detected between the receiving amplifier (8) for applying to the microcomputer (9), the output of the microcomputer (9) and the voice synthesis section 12 A transmission amplifier 15 for amplifying the power and connecting the communication path switches 3 and 4, a ring detector 13 for detecting a ring signal from the trunk lines L1 and L2, and the password confirmation circuit. (18) and the output of the shock absorber (5) to the microcomputer (9) and the control signal of the microcomputer (9), the communication path switch (3), (4), the melody generator (16) and And a multiplexer (14) for transmitting to the call switch (S1) of the trunk line connection unit (1). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
