Claims (2)

데이타 통신의 흐름을 제어하는 제2중앙처리장치(10)와, 프로그램을 저장하고 있는 롬(20)과, 데이타를 일시 저장하는 램(30)과, 듀얼 입출력 포트로 구성되어 A포트는 각각 상이한 전송속도를 갖는 제1 및 제2데이타 가입자에 접속하고, B포트는 교환기의 스위칭회로에 접속하여 데이타의 입출력을 제어하는 제1 및 제2입출력장치(40,50)를 구비한 데이타 통신 서비스 시스템에 있어서, 발신측 데이타 가입자에서 데이타 출력시 A포트로 입력하는 수신 데이타를 절단요구 분석용으로 메모리에 저장하는 동시에 B포트를 통해 스위칭회로로 출력하는 제1과정과, 상기 제1과정 수행후 스위칭회로를 통해 B포트로 데이타 수신시 수신한 데이타를 메모리에 저장하는 제2과정과, 상기 제2과정 수행후 메모리에 데이타 존재시 저장한 데이타를 A포트를 통해 착신측 데이타 가입자로 출력하는 제3과정과, 상기 제1,2,3과정을 수행하지 않고 있을시 절단 요구 데이타 수신 유무를 검사하여 데이타의 흐름을 제어하는 제4과정으로 이루어짐을 특징으로 하는 데이타 교환기의 데이타 전송방법.A second port is composed of a second central processing unit 10 for controlling the flow of data communication, a ROM 20 storing a program, a RAM 30 temporarily storing data, and a dual input / output port. A data communication service system having first and second input / output devices (40, 50) connected to the first and second data subscribers having a transmission rate and the B port connected to a switching circuit of an exchange to control input / output of data. In the first step of storing the received data input to the A port when the data output from the source data subscriber to the memory for cutting request analysis and output to the switching circuit through the B port, and switching after performing the first process A second process of storing the data received in the memory upon receiving the data through the circuit B through the circuit; and the data stored in the memory when the data exists in the memory after the execution of the second process through the A port. A third process of outputting to another subscriber and a fourth process of controlling the flow of data by checking whether or not to receive the truncation request data when the first, second, and third processes are not performed. Data transfer method. 제1항에 있어서, 데이타의 흐름을 제어하는 제4과정이 A포트 수신영역이 저장데이타로 부터 절단요구인가 검사하며 절단요구일시 통신로 절단요구 신호를 발생하고 종료하는 제1단계와, 상기 제1단계에서 절단요구 상태가 아닐시 램의 B포트 수신영역 데이타가 소정 제1크기 이상 저장되었는가 검사하며, 제1크기 이상 저장되었을시 B포트를 통해 전송 중단용 데이타를 전송하고 리턴하는 제2단계와, 상기 제2단계에서 B포트 수신영역에 저장한 데이타가 상기 제1크기 이하일시 소정 제2크기 이하이며, 전송 중단상태인가 검사하며 아닐시 리턴하는 제3단계와, 상기 제3단계에서 B포트 수신영역의 저장데이터가 상기 제2크기 이하이며 전송 중단상태일시 B포트를 통해 전송 계속용 데이타를 전송하고 리턴하는 제4단계로 이루어짐을 특징으로 하는 데이타 교환기의 데이타 전송방법.The method of claim 1, wherein the fourth step of controlling the flow of data comprises: a first step of checking whether the port A receiving area is a cutting request from the stored data, and generating and terminating a cutting request temporary communication path cutting request signal; In the first step, when the cutting request state is not in the state, the B port receiving area data of the RAM is stored in a predetermined first size or more, and when the storage is larger than the first size, the second step of transmitting and returning data for transmission interruption through the B port. And a third step of checking whether the data stored in the port B receiving area in the second step is less than or equal to the predetermined second size when the first size is less than or equal to the first size, and stops the transmission. And a fourth step of transmitting and returning data for continuous transmission through the port B when the data stored in the port receiving area is less than or equal to the second size and the transmission is interrupted. Data transfer method of ventilation. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
