Abstract:
1. A cable television (CATV) entry adapter having an entry port, a passive port and a plurality of active ports for communicating CATV signals between a CATV network and subscriber equipment and also communicating Multimedia over Coax Alliance (MoCA) signals between MoCA enabled subscriber equipment connected to the passive and active ports in a subscriber premises MoCA network, the CATV entry adapter comprising: a first bidirectional splitter/combiner, within the CATV entry adapter, having a common terminal and first and second signal component legs to communicate CATV downstream and upstream signals with the CATV network, the first splitter/combiner splitting the CATV downstream signals at its common terminal into split active and passive CATV downstream signals at each of its first and second legs corresponding and also combining active and passive CATV upstream signals at the first and second legs into a single signal at its common terminal; a second bidirectional splitter/combiner, within the CATV entry adapter, having a common terminal and a plurality of separate signal component legs to communicate the CATV downstream and upstream signals to and from a plurality of the MoCA enabled subscriber equipment, the second splitter/combiner splitting the active CATV downstream signals at its common terminal into split active CATV downstream signals at each of its separate legs and also combining the active CATV upstream signals at its separate legs into a single signal at its common terminal; an active-side directional coupler, within the CATV entry adapter, having a input port, a through port, a main leg between its input and through ports, a coupled port and a directional leg between its input and coupled ports to communicate the active CATV downstream and upstream signals to and from the second bidirectional splitter/combiner, wherein the active CATV downstream signals are prevented from passing between the active-side directional coupler through port and the active-side directional coupler coupled port; a passive-side directional coupler, within the CATV entry adapter, having a input port, a through port, main leg between its input and through ports, a coupled port and a directional leg between its input and coupled ports to communicate the passive CATV downstream and upstream signals to and from the first bidirectional splitter/combiner, wherein the passive CATV downstream signals are prevented from passing between the passive-side directional coupler through port and the passive-side directional coupler coupled port, wherein: the common terminal of the first bidirectional splitter/combiner is operatively connected to the entry port; the separate signal component legs of the second bidirectional splitter/combiner are connected individually to the active ports which are connected to the plurality of the MoCA enabled subscriber equipment; the main leg of the passive-side directional coupler is operatively connected between the passive port and the first leg of the first bidirectional splitter/combiner, wherein the passive port is connected to the MoCA enabled subscriber equipment; the main leg of the active-side directional coupler is operatively connected between the input port of the second bidirectional splitter/combiner and the second leg of the first bidirectional splitter/combiner; the coupled ports of the passive-side and active-side directional couplers are operatively connected together to establish a MoCA bypass path for conducting the MoCA signals between the passive and active ports through the taps legs of both directional couplers, the MoCA signals are isolated from the respective through port of each of the directional couplers; and a MoCA signal frequency resection filter, within the CATV entry adapter, connected between the common terminal of the first signal splitter/combiner and the CATV entry port to operatively prevent a conduction of the MoCA signals from passing through the first bidirectional splitter/combiner onto the CATV network, but allowing the active CATV upstream signal and the passive CATV downstream and upstream signals to pass without impairment.
