摘要
着重介绍在HFC双向网络中开展各种宽带接入服务时回传通道的调试、测试方法。阐述了新的HFC双向网络回传通道的传输、调试理念 ,以简单而有效的方法使回传通道工作在最佳状态 ,从而使回传应用设备能稳定。
This article mainly introduces the methods of debugging and testing upstream channel when proceeding broadband connecting services. It expounds new idea of transmission and debugging about HFC bilateral network upstream channel, to make the upstream channel work at the best state in a simple the effective way, so that the devices of the upstream channel can run stably and reliably.
