This ebook explains how DOCSIS Proactive Network Maintenance (PNM) enables cable operators to transition from reactive break-fix operations to predictive network management by identifying impairments before subscribers experience service degradation. Using data collected from CMTS platforms and connected cable modems, PNM analyzes upstream frequency response, micro-reflections, group delay, ingress, and signal quality to accurately locate network faults. The guide highlights capabilities such as geolocation mapping, correlation of modem impairments, Full Band Capture (FBC), OFDM analysis, and upstream spectrum monitoring, allowing technicians to identify both in-home and outside plant issues before dispatching field crews. Benefits include 10–40% fewer truck rolls, reduced operational expe
