摘　　要：对将广电网中采用的DTI(有线电缆数据服务定时接口)时间同步技术应用到通信网中进行了探索性研究,结合DTI的技术特点,分析了DTI在通信网中所需解决的关键问题,得出DTI技术在进行参数转换后可移植到通信网中成为UTI(通用定时接口)技术的可行性结论,最后对UTI技术在通信网中的应用场景进行了分析与展望。In this paper,we make an exploratory study on the applications of the time synchronization technology named DOC-SIS Timing Interface (DTI)adopted in the radio and television networks to communication networks,analyze the key issues re-quired to be solved for its applications in communication networks in connection with the technical characteristics of DTI and conclude that it is feasible for the DTI technology to be transplanted to the communication networks after parameter conver-sions and become Universal Timing Interface (UTI)technology.Finally,we analyze and look into the prospect of the applica-tions of the UTI technology in the communication networks.
