1. A cable television (CATV) entry adapter for conducting downstream and upstream CATV signals between a CATV network and an at least one subscriber device at a subscriber premises and for conducting in-home network signals between multiple subscriber devices at the subscriber premises connected in an in-home network, the CATV signals occupying a CATV frequency band which is different from an in-home network frequency band occupied by the in-home network signals, the CATV entry adapter comprising:

  • a CATV entry port for connection to the CATV network;

    a plurality of network ports each for connection to one of the multiple subscriber devices;

    a signal splitter having an input terminal and at least two output terminals, wherein each of the at least two output terminals is connected to one of the plurality of network ports; and

    an in-home network frequency band rejection device connected between the CATV entry port and the input terminal of the signal splitter, wherein a first terminal of the in-home network frequency band rejection device is directly connected to the CATV entry port, and wherein a second terminal of the in-home network frequency rejection device is directly connected to the signal splitter input terminal, and wherein both upstream and downstream CATV signals pass through the in-home network frequency band rejection device, and wherein the in-home network frequency band rejection device blocks transmission of the in-home network signals from being conducted to the CATV entry port and the CATV network.
