Abstract
Proactively identify cable network impairments based on telemetry data from customer-premises equipment (CPE) devices is disclosed. In some embodiments, a maintenance service retrieves telemetry parameters from CPE devices at a customer site communicatively coupled to a cable network infrastructure. The maintenance service analyzes the telemetry parameters to detect cable network impairments experienced by the CPE devices at the customer site (based on, e.g., whether a telemetry parameter from any CPE devices fails a corresponding telemetry threshold, whether the same telemetry failure is experienced by all CPE devices at the customer site, whether other neighboring customer sites also experience the same failure on all CPE devices, and/or whether a high post main tap (HPMT) parameter and an HPMT magnitude (HPMTM) parameter for the customer site fail corresponding thresholds, according to some embodiments). The maintenance service then assigns a maintenance classification that indicates a recommended service technician type for the customer site.
