Abstract
본 발명은 디지탈 케이블 TV의 1.2G 광전송장치에 관한 것으로, 특히 51M 프레임의 구분 데이타가 삽입된 채널 고유번호 비트(Channel Identification Bit : CIB)를 이용하여 51M 프레임을 24채널로 구분하여 전송하고, 상기 채널 고유번호 비트(CIB)의 데이타를 입.출력 어드레스로 사용하여 프레임 재정렬을 위한 스위치부를 제어하기 위한 채널 고유번호 비트를 이용한 1.2G 광전송장치에 관한 것으로, 1.2Gbps 광전송장치 51M 프레임내의 채널 고유번호 비트를 이용하여, 상기 채널 고유번호 비티(CIB)에 24개의 프레임 구분 데이타를 입력하므로써, 별도의 64Kbps 시리얼 데이타 채널 없이도 프레임 구분이 가능해져 24개의 64Kbps 데이타 채널을 확보하도록 구현함을 특징으로 한다.The present invention relates to a 1.2 G optical transmission apparatus of a digital cable TV, and more particularly, to a system and method for transmitting a 51M frame by dividing a 51M frame into 24 channels using a Channel Identification Bit (CIB) The present invention relates to a 1.2G optical transmission apparatus using a channel specific number bit for controlling a switch unit for frame reordering by using data of a channel unique number bit (CIB) as an input / output address. In a 1.2Gbps optical transmission apparatus 51M frame, Bit data is input to the channel specific number bit (CIB) using the bit, so that it is possible to classify the frame without using a separate 64Kbps serial data channel, thereby securing 24 64Kbps data channels.
