Autonomous Fault Prediction in Coaxial Cable Data Networks (DOCSIS)

DOCSIS是一种电信标准，用于将数据和电视频道从电缆调制解调器终端系统(CMTS)**传输到家用电缆调制解调器。DOCSIS使用一种众所周知的功能，称为预均衡。预均衡是通过**分析CMTS的输入信号质量来完成的。它确定电缆调制解调器在**传输信号以克服上行损害之前需要对信号应用的校正。然后，CMTS将均衡器值发送到电缆调制解调器以更新其预均衡器。**这将导致上行信噪比(SNR)的显著改善，从而为用户带来更好的**体验质量。主动式网络维护(PNM)工具监控电缆调制解调器，并从所有电缆调制解调器收集预均衡器**信息。来自每个调制解调器的预均衡器值揭示了关于每个调制解调器可能具有的**损害类型的信息。在本项目中，我们将扩展ClearCables Connects的PNM工具，以持续监控**DOCSIS网络，生成早期预警指标，识别电缆线路或设备的变化并预测故障。**

DOCSIS is a telecommunications standard for delivering data and TV channels from a cable modem termination system (CMTS)**to a home cable modem. DOCSIS uses a well-known feature called pre-equalization. Pre-equalization is accomplished by**analyzing input signal quality at CMTS. It determines the correction that a cable modem needs to apply to the signal before**transmitting it to overcome upstream impairments. The CMTS then sends equalizer values to the cable modem to update its preequalizer.**This will result in significant improvement in upstream signal to noise ratio (SNR), which in turn translates to a better**quality of experience to the subscriber. Proactive Network Maintenance (PNM) tools monitors cable modems and collects preequalizer**information from all of them. The pre-equalizer value from each modem reveals information regarding what type of**impairments each modem may have. In this project we will extend Clearcables Connects' PNM tool to continuously monitor**DOCSIS networks, to generate early warning indicators that identify changes in cable lines or plants and to predict faults.**
