摘要
北京地铁各条线路建设时期不同,有的设备已不能满足发展要求,需要进行改造。城域网多业务传送平台(MSTP,Multi-Service Transport Platform)能够满足多业务传送要求。北京地铁八通线传输系统采用MSTP的SDH+ATM技术,正在改造的1、2号线传输系统采用基于SDH的MSTP技术。
Because the lines of Peking subway were developed during different period of time, some equipment eouldnt satisfy the demands of development and needed to be renovated. MAN multi-service transport platform technology can meet the demand of multi-service transmission. MSTP over SDH ＋ ATM was adopted in the transmission network of the Batong Line of Beijing subway, while MSTP over SDH subway L1 ＆2 were adopted in the transmission network for Line 1, 2 under renovation.
