Abstract

본 발명은 디지탈 키폰 전화기의 직렬접속 장치에 관한 것으로, 특히 주장치 1포트에 두대의 키폰전화기를 직렬로 접속시켜 가입자 용량을 배가시키고자 한 디지탈 키폰전화기의 직렬접속장치에 관한 것으로서, 이러한 본 발명의 목적을 주장치와의 디지탈 신호를 송수신하는 디지탈 송수신부(1)와, 상기 디지탈 송수신부(1)의 출력데이타에 따라 주키폰전화기(A) 전체 동작을 제어하는 제1중앙처리장치(2)와, 상기 디지탈 송수신부(1)에서 출력된 디지탈음성신호를 아날로그 음성신호로 변환하고 아울러 그 역변환을 하는 제1, 제2코텍(4)(6)과, 상기 제2코텍(6)에서 얻어진 음성신호를 부키폰전화기(B)에 전송하기 위한 하이브리드 트랜스(HT)와, 상기 제1중앙처리장치(2)에서 출력된 데이타를 부키폰전화기(B)에 접속하는 제1, 제2데이타 접속부(8)(9)와, 상기 제2데이타 접속부(9)에서 얻어진 데이타를 인가받아 부키폰전화기(B) 전체동작을 제어하는 제2중앙처리장치(10)와, 상기 하이브리드 트랜스(HT)에서 얻어진 음성신호를 접속하는 음성신호 접속부(12)를 구비함으로써 달성된다.The present invention relates to a serial connection device of a digital key phone, and more particularly, to a serial connection device of a digital key phone telephone intended to double subscriber capacity by connecting two key phone telephones serially to a port of a main device. A digital transmitting / receiving unit (1) for transmitting and receiving a digital signal to and from a main device, and a first central processing unit (2) for controlling the overall operation of the primary key phone (A) according to the output data of the digital transmitting / receiving unit (1); The first and second cortecs 4 and 6 converting the digital audio signal output from the digital transceiver 1 into an analog audio signal and performing reverse conversion thereof, and the voices obtained from the second cortec 6. Hybrid transformer HT for transmitting the signal to the secondary phone telephone B, and first and second data connection units for connecting the data output from the first central processing unit 2 to the secondary phone telephone B; 8) (9) and the second The second central processing unit 10 which receives the data obtained from the data connection unit 9 and controls the entire operation of the secondary phone telephone B, and the audio signal connection unit 12 which connects the audio signal obtained from the hybrid transformer HT. Is achieved.
