Transmission and multiplexing - generic requirements for synchronization networks - part 6 - 1 : timing characteristics of primary reference clocks endorsement of the english version en 300462 - 6 - 1 v 1 . 1 . 1 1998 - 05 as german standard 传输和多路复用.同步网络的一般要求.第6 - 1部分:原始
Therefore , it is necessary to mount timing system alone in synchronization network node and the place where there are more telecommunication equipments and the important hinge , which supplies the primary synchronization signal conformed to the standard 因此,有必要在同步节点处或通信设备较多的地方以及通信网的重要枢纽处,单独设置时钟系统,对所在的通信楼的设备提供合乎标准的同步基准信号。
Bits supplies the synchronous timing signal to these equipments inside the telecommunicationt building , such as dps , atm , no . 7 , dxc , tm & adm in sdh , don and in etc . the related techniques are involved in the content of synchronization ne twork , timing distribution , the timing signal transportations x impairments etc . the second chapter tells the structure and the function of the building integrated timing system . the third chapter summarizes the digital synchronization network techniques , which emphasizes the basic concept of synchronization networks analyzes the necessity of building the synchronization network and introduces all kinds of synchronization methods . the fourth chapter represents the transportation of the synchronization signal 本文第二章讲述了通信楼综合定时系统的构成及作用:第三章概述了数字同步网技术,着重描述了同步网的基本概念,分析了建立同步网的必要性,讲述了各种同步方法;第四章阐述了同步定时信号的传输;第五章介绍了bits设备所支持的同步状态消息;第六章、第七章为本文的重点,通过对时钟信号建立数学模型,从理论上分析时钟内部噪声和相位瞬变产生时钟定时信号损伤的原理,企图寻找到更好地控制频率漂移的方法。
Timing & synchronization is a key technology in digital communication network . building integrated timing system ( bits in short ) equipment is the most common synchronization supply equipment in digital synchronization network , which also is the key equipment supplying telecommunication network signal 定时与同步是数字通信网的一项关键技术,通信楼综合定时系统( buildingintegratedtimingsystem ,简称bits )设备是数字同步网中最常见的同步供给设备,也是提供电信网同步信号的关键设备。
