DOCSIS Proactive Network Maintenance (PNM)

PreEqualization Analyzer is a Proactive Network Maintenance (PNM) tool that allows you to find and fix micro-reflections and group delay caused by issues like loose connectors, corroded fittings and cracked or bent cables before they impact your subscribers. We use a methodology developed by CableLabs to analyze the pre-equalization data from the CPE on the cable network to determine which devices are being impacted and the approximate location of the fault. The data and mapping features in PreEqualization Analyzer can help you quickly improve the quality of your cable plant, increase the efficiency of your maintenance staff, and provide a better experience for your customers. Plus, you can access multiple tools that are invaluable for cable plant diagnostics from a single interface.
