Abstract: A network communication device includes an input port configured to receive a downstream signal from a network, a first output port in communication with the input port and configured to receive a first reduced-power version of the signal received at the input port, one or more second output ports, and a converting circuit configured to receive a second reduced-power version of the signal received at the input port, down-convert a high-frequency portion thereof, and produce a down-converted signal. The one or more second output ports receive at least a portion of the down-converted signal.

Abstract: A passive entry adapter system includes an external band rejection filter connected to an external network; an entry adapter connected to the external band rejection filter, an input port connecting the entry adapter to the external network; a directional coupler connected to the input port; a frequency-based signal separation device connected to a first terminal and comprising a high-pass terminal, and a low-pass terminal; a splitter connected to the high-pass terminal, where the splitter is configured to be connected to one or more first types of devices; and a broadband output port connected to a second terminal of the directional coupler. The broadband output is configured to be connected to one or more second types of devices. The entry adapter and the external band rejection filter are configured to prevent signals from a frequency band associated with in-network communications produced within an internal network from reaching the external network.

Abstract: An entry adapter for a cable television (CATV) network includes a first signal separation device configured to separate downstream CATV signals into a first downstream high-frequency signal and a first downstream low-frequency signal based on a first cutoff frequency, a second signal separation device configured to separate the downstream CATV signals into a second downstream high-frequency signal and a second downstream low-frequency signal based on a second cutoff frequency, and a signal frequency sensor and selector device in selective communication with the first and second signal separation devices.
