摘要
TU+PJE是由于SDH网络时钟不同步引起,通过对其产生的机理进行认真分析,从检测点沿业务传输方向向上查找,然后找到网络中不同步的站点。检测到是由于的时钟板故障,提供的时钟源质量不好,导致无法锁定跟随的时钟源,进而排除故障。
TU＋ PJE is as result of asynchronous SDH Network. Through careful analyzing the causation of TU ＋ PJE, lookup upward direction from the test point along the transmission, then found asynchronous NE （Network Element） in the Network. Because of the clock module＇ s fault , it lead to the failure which can not lock the clock source, thereby troubleshooting.
