摘要
首次提出一种利用光同步数字传送网的2.048Mbit/s信号传送高精度时间编码信号的方法和实验结果。它可以使整个通信网的交换机、计费系统、网管系统、基站控制器等设备实现与UTC的时间同步。目前的实验证明,时间同步的不确定度优于±5μs。
The paper issues a new method and its experiment results of transferring high accuracy standard time signal by SDH 2.048 Mbit/s channel, which can realize the time synchronization with UTC of equipments in whole communication network, such as switching, billing systems, network administration systems, mobile communication base station controllers and so on. The present experiments certify that the accuracy of time synchronization is better than ±5 μs.
