摘要
针对768kbps高速数据传输异常的问题,根据国内外标准相关内容,确定了同步传输中数据与定时信号间的时序关系,通过与工程应用中实测波形的比较,发现设备接口间信号时序关系存在不匹配,据此对问题进行了分析,进一步查找原因,并使故障得到复现,最后为彻底排除隐患提出了解决措施。
In order to solve the problem of abnormity in 768 kbps high speed data transmission, at first a right timing relationship between synchronous data and timing circuits according with the international and domestic criterions is introduced. Through comparison with the testing waveforms in engineering application, the timing relationship between the equipment interface is found unmatched. The problem is hereby analyzed, the cause is researched and the abnormity phenomenon is represented. At last measures to resolve the trouble thoroughly are put forward.
