E1-AIS指的是信息净荷为全“1”,TU-AIS指的是信息净荷与支路单元指针都是“1”。传输收交换侧信号为全“1”时相应支路板端口上报UP-E1-AIS,传输发向交换侧为全“1”时相应支路板端口上报DOWN-E1-AIS。T-ALOS告警抑制UP-E1-AIS,TU-AIS抑制DOWN-E1-AIS。其实E1-AIS这个告警对传输侧解决故障意义不大,主要是协助交换侧解决故障,重点还是关注T-ALOS和TU-AIS,可以把E1-AIS的两个告警屏蔽掉。

<p>谢谢楼上的详细解释,基本有所了解了</p><p>那应该说DOWN-E1-AIS是在LPT侧收交叉板信号检测的吧...但是UP-E1-AIS是什么地方检测的呢?</p><p>还有,TU-AIS应该是检测到V5全"1"就抱了吧,支路单元指针都是“1”应该是报TU-LOP吧,当然TU-AIS对TU-LOP也是屏蔽的</p>

<p>TU-AIS主要有两个原因会上报,一是高级别告警下插全“1”导致的,比如说R-LOS,R-LOF等,二是业务配置错误导致的。业务配置错误会上报HP-TIM,HP-SLM,HP-LOM等告警,这些会下插全“1”信号;综上所述,TU-AIS告警肯定是这个TU-12结构都是“1”才会上报,只不过检测的时候只看<span lang="EN-US" twffan="done"><font face="Times New Roman">V5</font></span><span twffan="done" style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'mso-hansi-font-family:';">字节(</span><span lang="EN-US" twffan="done"><font face="Times New Roman">b5-b7</font></span><span twffan="done" style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'mso-hansi-font-family:';">)是否全“1”。<span style="LEFT: -2.6%; COLOR: #5f5f5f; FONT-FAMILY: &quot;Wingdings 3&quot;; POSITION: absolute; mso-special-format: bullet;">[</span><span style="FONT-FAMILY: 华文细黑; mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial;">若收指针值超出允许范围,或连续收到</span><span lang="EN-US" style="mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial; mso-fareast-language: ZH-CN;">8</span><span style="FONT-FAMILY: 华文细黑; mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial;">帧以上</span><span lang="EN-US" style="mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial; mso-fareast-language: ZH-CN;">NDF</span><span style="FONT-FAMILY: 华文细黑; mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial;">,则本端在相应通道上产生</span><span lang="EN-US" style="mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial; mso-fareast-language: ZH-CN;">TU-LOP</span><span style="FONT-FAMILY: 华文细黑; mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial;">告警,下插全</span><span style="FONT-FAMILY: Arial; mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial;">“</span><span lang="EN-US" style="mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial; mso-fareast-language: ZH-CN;">1</span><span lang="EN-US" style="FONT-FAMILY: Arial; mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial; mso-fareast-language: ZH-CN;">”</span><span lang="EN-US" style="FONT-FAMILY: 华文细黑; mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial; mso-fareast-language: ZH-CN;"> 。所以TU-LOP告警是先检测有问题,再下插全“1”的。</span></span></p><p><span twffan="done" style="FONT-FAMILY: 宋体; mso-ascii-font-family: 'mso-hansi-font-family:';"><span lang="EN-US" style="FONT-FAMILY: 华文细黑; mso-fareast-font-family: 华文细黑; mso-hansi-font-family: Arial; mso-fareast-language: ZH-CN;">UP-E1-AIS应该是PPI模块检测的。</span></span></p>

那么根据华为的定义,这个设备的TU-AIS应该属于TTP检测的范畴喽,
华为的设计种,这个监测点(查V5字节)是在CC盘还是TP盘?

看了楼上各位兄弟的解释,让我也对TU-AIS有了一定的认识,今后还有很多不明白的地方,还请各位大虾赐教。
