Design and Implementation of Time Automatic Synchronous System Based on TCP/IP

KANG Xiaodong1,2,ZHENG Chengjun1,3,DAI Weidi1(1.School of Electronic & Information Engineering,Tianjin University,Tianjin 300072;2.Department of Medical Image,Tianjin Medical University,Tianjin 300070;3.Beijing Telecom Project Bureau,Beijing 100061)  
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.
