ECI XDM常用告警說明

1、10/10 xm告警列表 傳輸告警 告警名稱可能的原因LOS光信號丟失,產生的原因有：光纖斷裂,光纖沒有連接好或者光傳輸失敗 LOD有光但是業(yè)務信號丟失OP指針丟失，一般由設備失敗或不匹配或時鐘引起。LF楨丟失AI上游失敗,上游有告警存在由設備發(fā)送AIS。AU/T A上游失敗，上游有告警存在由設備發(fā)送AISSS服務失敗，由AUTU AIS引起。EXC誤碼超限。E信號劣化。DI遠端信號失敗。AI跟蹤字節(jié)不匹配,一般由收到的J0J/J字節(jié)不匹配引起。I信號未裝載，一般由于路由不通引起。UNEQ有效載荷信號標簽不匹配。PLM子針調整超限。LOM連續(xù)10秒嚴重誤碼秒.LOMC近端5M誤碼塊超限。LOA

2、近端15M誤碼秒超限.SM近端1M嚴重誤碼秒超限。MSPL Failure近端1天誤碼塊超限.PJ15M近端天誤碼秒超限。UT近端天嚴重誤碼秒超限.BENE 15 Min遠端M誤碼塊超限.SNE 1 Min遠端15M誤碼秒超限。SENE5 in遠端15M嚴重誤碼秒超限。BENE 1 ay遠端1天誤碼塊超限。NE 1 D遠端1天誤碼秒超限。SESNE Day遠端天嚴重誤碼秒超限。BBEFE15 in跟蹤字節(jié)不匹配,一般由收到的J0/J1字節(jié)不匹配引起。SFE 5Min信號未裝載,一般由于路由不通引起。EF 1 in有效載荷信號標簽不匹配.BEF 1 Day子針調整超限.ESF Day連續(xù)0秒嚴重

3、誤碼秒。SSFE 1 a近端1M誤碼塊超限。Trnmissn larms reated Optialpoer conrpn Lss Chnge(no）：Sn可以理解為兩個站點功率監(jiān)控點之間的總衰耗. 當之間的衰耗值變化范圍超出允許的門限時(默認設置為05），就會出現(xiàn)此告警。處理之前需要確認一下告警的產生是否暫時的。這種情況多出現(xiàn)于調試階段，經常會關閉和開啟某個TU單元的激光器導致站點之間的衰耗值出現(xiàn)變化。類似的此種情況在恢復后告警自動消失。如果是由于光纜衰耗割接等引起的一些不可恢復性的衰耗,就需要將放大器的GAIN增益調整到新的數值以適應新的鏈路狀態(tài).具體的做法只需打開Ga窗口，Aopt然后p

4、py就可以了。ut of rakngLmittio(Mar)：放大器的自動跟蹤功率變化有個范圍，默認為53dB,一當超出這個范圍,就會有告警，同時還會伴隨Sa Los Change。由于此時功率變化的范圍比較大,必須要認真檢查是否線路的衰耗或者板卡等有故障。例如光纖插拔之后沒有復原到位，或者增加或減少了波道的輸入。如果是由于光纜割接引起的光纜衰耗的增加和減少，意味著沒有辦法回到系統(tǒng)初始的狀態(tài),整個時候同樣也可以改變放大器的ai來消除告警。ut OStCalty(aor):放大器的增益是有限的，同時自動跟蹤功率變化也有一個限度。放大器其實是通過調節(jié)自身之前的可調衰耗值來調節(jié)在線路中的增益的.當線

5、路衰耗的變化無法使得放大器調整到合適的增益以滿足要求的輸出功率的時候,就會有此告警。此時需要建議客戶能否將線路的衰耗盡量恢復到初始值.如果不行，只能將放大器的既定輸出更改到合適的值。保證放大器能夠在正常范圍內工作。WR_TL_OUT_OF_TRAKING_IIATONRqured coretio s greater thnTakngLimit an ad beenuppressedWCTLSPAN_LOS_CNGEReuiredcorrecin geter tha wAlrm Tesd an had bn aePR_CL_T_OF_ET_CAABILIYReired oretioniseyod
