The input data of the multiplexing adopts 8 channels with the speed of 2mb / s, and those of the last two channels are " 0 " and " 1 " respectively, in order to improve the transimision effeciency and deminish the complexity of encode and electronic circuit concerned, furthermore, it makes the synchronous signal acquisition more easier
數字復接中採用八路2m口數據輸入，其中后兩路採用直接輸入「 0 」碼或「 1 」碼的方法，提高了信息傳輸的有效性，便於提取幀同步碼，降低了編譯碼過程的復雜性，同時也降低了系統的電路復雜程度。 -
And software method can resolve d channel ' s work for its less data communication ; 3 ) cpu 80c152 is synchronized with mc145572 by a simple synchronous circuit, avoiding the complex fpga interface circuit ; 4 ) data transmission use dma, which reduces the delay of data transmission and cpu occupying ; 5 ) 8bit software look - up table method can achieve 16bit crc quickly, which reduces the resource of both hardware and software
對通信數據量相對小的d通道，採用軟體實現裝幀與解幀。第三，採用結構簡單的外部同步時鐘電路實現80c152和接入晶元mc145572的同步傳輸，巧妙地避開了復雜的fpga介面電路。第四，利用dma技術完成數據快速收發，降低了數據傳輸時延及cpu佔用率。
