Abstract

Abstract: The gaining and disseminating of the essential technologies, NTP, GPS and UTC in PSTN, are discussed. Based on the above analysis, several schemes are presented and compared for the automatic timing synchronization algorithm, and the optimization algorithm is discussed too. Synchronous software’s for serial interface and network interface are developed according to the access methods of exchangers in network management system.

Key words: NTP, GPS, CUT, Switching network management system

摘要： 在对通信交换网关键技术（NTP、GPS、UTC）的获取及传播方式分析基础上，比较了时间同步算法的不同方案并讨论了最优的算法。根据网管系统的交换机接入方式，分别开发了串口同步程序和网口同步程序。

关键词: NTP, GPS, UTC, 交换网管系统
