如何查找网管告警及收发光情况.docVIP

如何查看网元当前告警：可以再该网元点击右键，然后出出现英文Current Alarms(当前告警) 再列表中Sevenity 显示的是告警级别 Critical为严重告警、Major为主要告警、Minor为次要告警、Warning为警告 再列表中ME Name显示的告警网元 再列表中Object Name显示的是发出这个告警的对象、槽位 再列表中Probable Cause显示的是产生这个告警的原因 再列表中Event Time显示的是告警时间 Alarm name告警名称 Probable Cause可能的原因 LOS信号丢失 Indicates a significant drop in receive signal level can be caused by broken fiber , fiber cuts , disconnected fiber or faulty optical transmitter. 指示光接口或电接口的收端没有信号输入。产生原因：接口收端电缆线断了，2M/155M头不好，没上业务等；光缆断了，光接口对端没发光等。 LOD数据丢失 Loss of Data represents the case in which optical LOS is not being detected but no signal transitions exist. 光接口收不到信号但又检测不到LOS时产生此告警。例如光接口连到纯光源上时产生LOD。 LOP指针丢失 Invalid pointers are received due to equipment failure or mismatch in signal mapping or timing problems. 设备故障，信号映射失配或时钟问题。 LOF帧丢失 Indicates no detect of frame alignment in the incoming signal 接收的信号中没有监测到帧队列 AIS告警指示信号 Indicates upstream failure . indicates that another alarm exists previous to the equipment sending the AIS. 指示上游失败。指示另外一个告警，即上游那个发送AIS信号的设备存在的告警。 AU/TU AIS管理单元或时隙的告警指示信号 Indicates upstream failure . indicates that another alarm exists previous to the equipment sending the AIS. 指示上游失败。指示另外一个告警，即上游那个发送AIS信号的设备存在的告警。 SSF服务信号失败 Server signal failure . Indicates failure in adaptation function due to AU_AIS or AU_LOP. 服务信号失败。指示基于AU_AIS 或 AU_LOP的相应功能失败。. EXC误码率过高 The Bit Error Rate (BER) on the incoming signal frame is higher than a specific configured threshold. 接收信号帧误码率高于一个特定门限值 DEG信号劣化 The Bit Error Rate (BER) on the incoming frame is higher than a specific configured threshold. This threshold is lower than the one specified for EXC 接收信号帧误码率高于一个特定门限值。但这个门限值低于产生EXC的门限值。 RDI远端接收失败 Remote defect indication received , indicating far end signal fail condition . 远端接收失败，指示远端失败情况。 RAI远端接收失败 Remote defect indication received , indicating far end signal fail condition . 远端接收失败，指示远端失败情况。 TIM通道匹配缺失跟踪指示 Trace Identifier Mismatch defect caused by a misprovisioning of the expected trace or misconnection (The
