A 65Mb/s Survivable Optical Fiber Ring Integrated Sevices Digital Network

舰载65Mb／s顽存式综合业务光纤环形数字网采用TDM传输和混合交换方式，具有面向ISDN的S0、S2接口和ETHERNET接口。它不仅具有高的可靠性与顽存性，而且以通信和传输一体化为设计目标，能够同时满足现代舰船内部通信的所有要求和数据与视频传输的需求。本文重点介绍该网的组成、帧结构、重配功能和用户-网络接口，并描述了适应更大规模容量的多环网结构。

A shipborne 65Mb/s optical fiber ring integrated sevices digiatal network is proposed which integrates communication and transmission into a complete system suitable for all demands of modern ship intercom and data, video transmission. A Time-Division Multiplex (TDM) technique and hybrid switching mode are used. The system posseses high reliablilty and survivability and offers ISDN oriented interface (S0 and S2)and ETHERNET interface. The network composition, TDM frame structure, reconfiguration function and user-network interface are discussed.Finally, multiring structure suitable for users with large-scale capacity is described.
