Claim 4:
5. A non-transitory computer-readable medium having stored thereon computer-executable instructions which, when executed by a processor device, cause the processor device to:
retrieve a plurality of telemetry parameters from each customer-premises equipment (CPE) device of a plurality of CPE devices of a customer site communicatively coupled to a cable network infrastructure, at least some of the telemetry parameters indicating a current quality of a downstream link or an upstream link between the cable network infrastructure and the corresponding CPE device, a current high post main tap (HPMT) telemetry parameter for the customer site, and a current HPMT magnitude (HPMTM) telemetry parameter for the customer site;
perform an analysis of the plurality of telemetry parameters from each CPE device of the plurality of CPE devices by causing the processor device to:
determine that a telemetry parameter of the plurality of telemetry parameters for a first CPE device of the plurality of CPE devices fails a corresponding telemetry threshold; and
responsive to determining that the telemetry parameter for the first CPE device fails the corresponding telemetry threshold, perform a second determination, for all CPE devices of the plurality of CPE devices other than the first CPE device, of whether the telemetry parameter fails the corresponding telemetry threshold;
in response to determining that the telemetry parameter fails the corresponding telemetry threshold for each of the plurality of CPE devices:
retrieve, by a maintenance service, the telemetry parameter from each CPE device of a plurality of CPE devices of a neighboring customer site communicatively coupled to the cable network infrastructure on a same infrastructure node as the customer site;
perform an analysis of the telemetry parameter from each CPE device of the plurality of CPE devices of the neighboring customer site; and
determine that the telemetry parameter for the plurality of CPE devices of the neighboring customer site does not fail the corresponding telemetry threshold;

in response to determining that the telemetry parameter fails the corresponding telemetry threshold for the plurality of CPE devices of the customer site and that the telemetry parameter does not fail the corresponding telemetry threshold for the plurality of CPE devices of the neighboring customer site, perform a third determination of whether the HPMT telemetry parameter for the customer site fails an HPMT drop logic threshold and the HPMTM telemetry parameter for the customer site fails an HPMTM drop logic threshold; and
responsive to the third determination evaluating to true, assign a maintenance classification to indicate that a technician is recommended for the customer site to address a drop issue that affects the customer site.
