Abstract

본 인터페이스장치는 공통선 신호방식의 신호링크 접속시, 64Kbps의 전송속도를 갖는 단말기와 V.35/RS422/RS499 방식으로 데이타를 전송하는 디지탈 교환기간을 인터페이스할 수 있는 것이다. 이를 위하여 본 장치는 디지탈 교환기로 부터 제공되는 제어신호에 의해 디지탈 교환기의 전송방식과 단말기에서 사용한 전송방식간의 전기적 특성을 검출하여 인터페이스모드를 규정하기 전기적 특성 규정부; 단말기로 부터 출력되는 데이타를 수신하는 수신단; 전기적 특성 규정부에 의하여인터페이스모드가 설정되어 수신단으로 부터 전송되는 데이타를 설정된 인터페이스모드에 따라 변환시켜 디지탈 교환기로 전송하기 위한 데이타변환 송신부; 전기적 특성 규정부에 의하여 설정된 인터페이스모드에 따라 디지탈 교환기로 부터 수신된 데이타를 변환하기 위한 데이타변환 수신부; 데이타 변환 수신부로 부터 전송되는 데이타를 단말기로 송신하기 위한 송신단을 포함하도록 구성된다.This interface device is capable of interfacing the digital switching period for transmitting data in the V.35 / RS422 / RS499 method with a terminal having a transmission rate of 64 Kbps when the signal link connection of the common line signaling method is used. To this end, the apparatus is characterized by detecting the electrical characteristics between the transmission method of the digital exchange and the transmission method used in the terminal by the control signal provided from the digital exchange electrical property defining unit; A receiving end for receiving data output from the terminal; An interface mode is set by the electrical characteristic specification unit, the data conversion transmitter for converting data transmitted from the receiving end according to the set interface mode and transmitting the data to the digital exchange; A data conversion receiver for converting data received from the digital exchange according to the interface mode set by the electrical property defining unit; And a transmitting end for transmitting data transmitted from the data conversion receiving section to the terminal.
