摘要
结合城市轨道交通通信系统现状,介绍了一种基于异步转移模式(ATM)的综合业务系统信息平台。阐述了ATM用于轨道交通通信业务的优势,并与同步数字传输系统(SDH)的技术性能作了比较。分析了一个基于ATM的城市轨道交通综合业务传输系统的实例。
Following the development of communication system in Urban Mass Transit, many intergrated service systems have been adopted. Based on modern technologies and corresponding to different environments, this paper presents a kind of information platform on ATM, compares it with other communication technologies such as SDH, and assesses its practical results through an example of UMT communication service upon ATM.
