    Abstract: Within a regeneration device, regenerate a first input signal having a first timestamp and an inadequate signal-to-noise ratio and bypass a second input signal having a second timestamp and having an adequate signal-to-noise ratio. With a central processing server coupled to the device, obtain, from a delay tracking database, a first delay associated with a first signal path for the first input signal and a second delay associated with a second signal path for the second input signal. With the server, cause to be sent downstream the regenerated first input signal together with the first timestamp and the first delay, and the non-regenerated second input signal together with the second timestamp and the second delay.

    Abstract: Automated determination of a timing offset for DOCSIS time protocol to provide precision time protocol accuracy. A cable modem receives, from a cable modem termination system (CMTS), a message that includes a timestamp that is correlated to a primary reference clock. The cable modem determines a downstream travel time representative of a period of time between a generation of the timestamp by the CMTS and a first timing reference point of the cable modem. The cable modem accesses an internal delay time representative of a period of time for the timestamp to travel from the first timing reference point to a second timing reference point of the cable modem, and sets a precision time protocol (PTP) clock of the cable modem to a time equal to the timestamp incremented by the downstream travel time and the internal delay time.

    Abstract: Methods and systems for an intelligent tap with dynamically configurable amplifier gain. The intelligent tap includes a filter configured to process a signal received from a service provider system via a hybrid fiber-coaxial network, an amplifier connected to the filter, the amplifier configured to apply a feedback controlled gain value to the signal to generate an output signal, where the feedback controlled gain value is based on a comparison of a target signal strength to a sampled output signal strength, and a signal strength measuring component connected to the amplifier in a feedback loop, the signal strength measuring component configured to sample the output signal, and compare a signal strength of a sampled output signal to the target signal strength to generate the feedback controlled gain value, where application of the feedback controlled gain value maintains the output signal at a constant amplitude pursuant to the target signal strength.

    Abstract: A network includes a centralized power and signal distribution device deployed at a communication closet at a site. The centralized device includes a switch controller connected to a direct current power supply. The network includes at least one customer premises termination device connected to the switch controller, an access apparatus deployed at each of the multiple customer premises, and a power over cable system to carry power and signals. Each access apparatus connected to the at least one customer premises termination device and to provide access to user devices. The switch controller power cycles at least one of the switch controller, the at least one customer premises termination device, or applicable access apparatus in response to a power cycle command from a controller when at least one of the switch controller, the at least one customer premises termination device, or any access apparatus fail to transmit a status signal.
