摘要
目前,OTN系统开始在铁路上大规模应用。OTN系统有多种保护机制,而铁路既有的SDH系统自身也有自愈保护机制。如何将OTN保护方式与SDH保护机制协调好是一个重要问题,为此研究协调技术,并总结实际应用中的注意事项。
The Optical Transport Network has be widely used in Chinese railway.OTN has multiple protection mechanism and SDH also has its self-recovery protection mechanism.How to coordinate their protection mechanisms remains as a major issue.Therefore the coordination technology for those protection mechanisms is studied and some precautions in practical application are summed up.
