論文摘要
在同步數位階層SDH (Synchronous Digital Hierarchy)通訊網路中塞取多工機ADM (Add Drop Multiplexer) /邊緣多工機TM (Terminal Multiplexer)設備透過設備解多工單體與接取網路DSLAM(Digital subscriber line access multiplexer)設備中繼光卡銜接,當中繼(Trunk)路由發生障礙(Failure)時,在無任何路由保護切換機制(Protection Switch)情況下,將無法利用保護切換機制先行排除障礙路由後在進行故障路由查修,以降低查修困難度,一般只能依據SDH網管告警列表依照障礙訊息或以信號折回測試(Loop Test)隔離障礙點方式找出路由故障原因,如此折回測試將會造成使用中路由訊務中斷。
一般如非大量誤碼秒ES(Error Second)、SES(Severly Errored Sceond)、BBE(Background Block Error)等誤碼所導致產生UAS(Unavailable Second)誤碼造成AISS(Alarm Indication Signal Second)、Loss of signal、Degraded signal等SDH網管電路主要訊務中斷告警(Major Alarm)原因,因為不至於造成電路中斷或嚴重影響訊務(Traffic)產生重大告警,在本論文中定義為「潛伏性障礙」。
本論文在實驗中將利用SDH網管針對設定故障電路開啟性能監測P.M .(Performance Monitoring)功能,並利用G.821及ITU-TG.826所提規範分析誤碼產生原因,如此將可充分利用SDH網管功能,不需要到現場就即可做遠端誤碼分析查修,待判斷分析障礙點確定後,再評估是否需要至現場做準確性高的障礙處理以降低查修困難度,故本論文實驗將著重於探討光纖網路之「潛伏性障礙」誤碼處理分析之技術研究,目前經第四章實驗一結果證明利用誤碼方向性分析研究確實能準確分析出障礙點,在未來可以做為設備維運及障礙查測的依據。

Abstract
In same step position social stratum SDH (Synchronous Digital Hierarchy) in communication network.Takes multiplex machine ADM (Add Drop Multiplexer) and edge multiplex machine TM (Terminal Multiplexer) the equipment can penetrate the equipment solution multiplex monomer with to receive network DSLAM (Digital subscriber line access multiplexer) the equipment relaying light card engagement.When the transmission route has the barrier and does not have in any route protection cut mechanism (Protection Switch) in the situation, Generally can only turns back the test based on the SDH network management warning tabulation barrier news or by the signal (Loop Test) to isolate the fault point way to discover the route breakdown reason. It is unable by any protection cut mechanism advance breaching of obstacles route, after reduces looks up repairs the degree of difficulty, is carrying on the breakdown route to look up repairs. But the present paper raises it“the latent barrier” to be unable by the SDH network management warning tabulation to ascertain and to turn back the test completely to create the news service interrupt.
For instance, Non-massive error code second, SES (Severly Errored Scond), BBE (Background Block Error) and error codes cause to produce UAS (Unavailable Second) the error code to create AISS, Loss of signal.SDH network management system is the main news service interrupt warning and so on degraded signal (Major Alarm) the reason, because does not send in creating the break or serious influence news serves (traffic ) to have the significant warning ,defines in the present paper as “the latent barrier”.
The present paper will monitor P.M. in the experiment using the SDH network management in view of the hypothesis breakdown electric circuit opening performance. (Performance Monitoring) the function And uses the canonical parse error code which ITUT-G.821 and ITU-TG.826 raises to have the reason .Then may use SDH network management system function fully, does not need to arrive at the scene then to make the far-end error code analysis to look up repairs .After judgment analysis fault point, and then appraises whether needs to make accurate high barrier processing to the scene to reduce looks up repairs the degree of difficulty .Therefore the present paper experiment in discussion optical fiber network it “the latent barrier” the error code processing parsing technique research.
At present passes through the fourth chapter to test one results proofs that May study using the error code directivity analysis can analyze the fault point accurately truly. We may do are Maintenance of equipment and Barrier service in the future.
