Abstract
A coaxial cable tap comprises a housing, and a faceplate coupled to the housing. The faceplate comprises a first directional tap port, and a diagnostic reverse (DR) port configured to receive a first upstream signal originating downstream from the coaxial cable tap, and inject a downstream test signal in a downstream direction. A hybrid fiber-coaxial (HFC) network comprises a headend, a first amplifier coupled to the headend, and a tap coupled to the first amplifier, configured to couple to a plurality of cable modems (CMs), and comprising a diagnostic forward (DF) port configured to receive a downstream signal originating from the first amplifier, and inject an upstream test signal in an upstream direction for reception at the headend.
