AN APPARATUS FOR SENDING CHANNEL INFORMATION OF 1.2GHZ OPTICAL DEVICE

摘要

The channel information transmission apparatus of the 1/2 Gigabit optical transmission apparatus of the present invention temporarily uses a 64 Kbps channel for transmitting channel classification information, and subsequently uses it as a transmission channel for M A information.;According to the present invention, the channel discrimination information generating unit 1 which counts the clock signal CLK and generates the channel discriminating information CH _{0 to} CH ₂₃ , and the channel discriminating information generating unit 1 are the channel discriminating information CH _0. ~CH ₂₃₎ a set value or more if hayeoteul generated in the selection signal generating unit (2) for generating a selection signal as well as Sikkim clear the channel indicator information generating section 1 to the initial state, the selection signal generating unit (2 ) Selector (3) for selectively outputting channel identification information (CH _{0 to} CH ₂₃ ) or MA information (DT _{1 to} DT ₂₄ ) of the channel identification information generator (1) according to the selection signal SEL generated. It is possible to improve the transmission efficiency of data by transmitting the channel identification information through the 64Kbps channel only in the initial time of the system operation, and after the channel is fixed by transmitting the MA information.
