Simple multi / demultiplexed 1.2 Gb optical transmission system using 8 channel classification information

摘要

In the present invention, 24 pieces of 51.8 Mbps frames are multiplexed and transmitted, and the demultiplexed signals are rearranged into 24 51.8 Mbps frames. In the 1 and 2 optical transmission devices, channel separation information is transmitted using only 8 of 24 64 Kbps channels, The present invention relates to a simple multi / demultiplexed 1.2-G optical transmission apparatus using eight channel identification information for use as a maintenance channel. In general, in a 1.2-G optical transmission apparatus using simple multi / demultiplexing, There is a problem that a channel for maintenance is not provided due to the use of all 24 64-Kbps channels for information transmission for transmitting the channel identification information. In order to solve this problem, in the present invention, Use only 8 of the 24 64-Kbps channels and use the remaining 16 channels as the data for maintenance And it was allowed to extract the location information using the 8 channel sorting information, and also so as to generate position information of the adjacent channels 24 Channel alignment is performed by maintaining the channel is configured for that.
