Claims (3)

종합정보통신망에서 데이타 전송방법에 있어서, 상기 종합정보통신망의 호 접속메세지로부터 채널번호, 송신측 전화에 따라 ISDN호처리 절차에 의해 접속을 완료하는 제1과정과, 상기 제1과정에서 접속이 링타입이 아니면 리턴되고 링타입 연결이면 접속 완료된 채널에 미리 정의된 용도를 할당하여 최초 호접속이 있는지를 확인하는 제2과정과, 상기 제2과정에 최초 호접속이 시작되었을시 회의를 시작하고 최초 호접속이 아닐시 단말리스트에서 다른 단말을 확인후 다른 하나의 B채널으로 호접속절차를 시작하는 제3과정과, 상기 제3과정에서 상기 B채널로 ISDN 호처리절차에 의해 접속을 완료하고 접속 완료된 채널에 미리 정의된 용도를 할당하여 회의 대기상태로 하는 제4과정으로 이루어짐을 특징으로 하는 종합정보 통신망에서 링타입 연결에 의한 화상회의시 데이타 전송방법.1. A data transmission method in an integrated information communication network, comprising: a first step of completing a connection from a call connection message of the integrated information communication network by an ISDN call processing procedure according to a channel number and a transmission-side telephone; A second step of determining whether there is an initial call connection by assigning a predefined purpose to the connected channel if the call connection type is a ring type connection; A third step of starting a call connection procedure to another B channel after confirming another terminal in the terminal list if the connection is not a call connection; and in the third step, the connection is completed by the ISDN call processing procedure on the B channel, And a fourth step of assigning a predefined purpose to the completed channel to make a conference waiting state. Data transfer method when the beat. 제1항에 있어서, 상기 데이터 전송중 오디오(A)전송채널은 오디오 채널과 데이타 채널로 나누어 사용토록 함을 특징으로 하는 전송방법.The method of claim 1, wherein the audio (A) transmission channel is divided into an audio channel and a data channel during the data transmission. ISDN의 데이터 전송방법에 있어서, 상기 ISDN BRI망에 링타입으로 접속하여 화상회의 등을 구현시 채널 할당은 비 대칭으로 할당됨을 특징으로 하는 전송방법.A method for transmitting data in an ISDN, the method comprising the steps of: allocating channel assignment to the ISDN BRI network in a non-symmetric manner when implementing a video conference by connecting the ISDN BRI network in a ring type; ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
