摘要
同步网为电信网内所有设备提供时钟及时间同步控制信号,从而使各节点设备的数字流实现正确有效的传送。分析了同步网的现状,结合甘肃电信数字同步网扩容改造工程,对数字同步网的时钟源建设、核心设备的时间同步以及网管系统建设提出了相应的改造方案,并对其中的关键技术进行了详细阐述。通过该方案的实施,能有效提高同步网的准确性和可靠性。
Synchronous network offers the clock synchronization and time synchronization control signal to the equipments in telecommunication network, thereby makes digital stream transmitted accurately and effectively. The insufficiency of synchronous network is analyzed, and incorporation with the optimization project of digital synchronous network of Gansu Telecom, a scheme of digital synchronous network optimization is proposed, it includes the establishment of reference clocks, time synchronization of BITS and network management. The critical technologies of the scheme are introduced in detail. Through put the scheme in practice, it can improve the veracity and reliability of synchronous network.
