Abstract

An apparatus includes a coupling, a diagnostic circuit, a cable modem circuit, a display, and a processing circuit. The coupling is configured to connect to a coaxial cable termination of a communication network, and is operable to receive broadband RF signals. The diagnostic circuit is operably coupled to the coupling to receive a first RF signal, and is operable to obtain diagnostic information regarding the first RF signal. The cable modem circuit is operably coupled to the coupling to receive a second RF signal, and is operable to generate data packets from the second RF signal. The cable modem is further operable to generate an RF transmission signal, the RF transmission signal including transmission data packets. The processing circuit is connected to the cable modem circuit and is operable to execute a web browser. The web browser is operable to cause the display to display information obtained from the data packets. The processing circuit is further operable to cause display of at least some diagnostic information.
