消除回传噪声建立监测平台

就影响HFC网络双向业务可靠性的主要症结——用户端的噪声汇聚问题，提出在靠近用户端采用一个自动控制开关来隔离回传噪声的解决办法和初步的试验数据，并且针对HFC网都是由各种厂家设备组合而成，难以形成统一的网管系统的现状，提出通过上述噪声隔离器内置应答器的固定回传电平来检测网络的运行状况，建立一种简单而有效的有线电视接入网的监测平台。

Eliminating Echo Noise to Establish Monitoring Platform of HFC Network

Noise convergence on customer end is the major influence of HFC network bidirectional service. This paper provides a solution of using an automatic control close to customers to isolate echo noise and the preliminary tentative data of the solution.HFC network is composed of the equipments from different factories, so it's difficult to form a unified network management system.Using fixed return level of a responder in the noise isolation to examine the network is brought forward to establish a simple and effective monitor platform of CATV access network.
