摘要
越南铁路统一线荣市至西贡通信信号改造项目荣市至芽庄段通信传输网设计中,在荣市和芽庄存在与既有不同厂家的SDH光同步数字传输设备对接的问题,对接方案有光口对接、电口对接两种,经过调查研究,并进行反复分析和交流,取得一致意见,采用155Mbit/s(E)和2 Mbit/s电口对接。
In view of Vinh to Nha Trang section communication transmission network designed for unified Vietnam Railway Line Vinh to Sai gon communication signal updating project, Vinh and Nha Trang both encounter equipment butting problems on account of SDH optical synchronous digital transmission equipment provided by different manufacturers. Butting scheme includes optical interface butting and electrical interface butting. Through investigation, study and repeated analysis and communication, consensus is reached to use 155 Mbit/s （ E） and 2 Mbit/s electric butting.
