Cunningham Telephone & Cable Eliminated Intermittent Ingress with Advanced Diagnostics
Cunningham Telephone & Cable enhanced its proactive maintenance strategy by combining ZCorum’s PreEqualization Analyzer with Upstream Analyzer to identify elusive ingress problems that previously required lengthy troubleshooting and repeated truck rolls. Traditional leakage detection often failed to locate intermittent noise sources, leading to slow internet, dropped phone calls, and frustrated subscribers. Using live return-path spectrum data alongside modem correlation reports, technicians quickly identified subscriber equipment contributing excessive ingress and verified repairs in real time without specialized monitoring equipment. The software-based tools enabled field staff to monitor network conditions from laptops and smartphones, accurately pinpoint noise sources, and confirm impr
