Abstract
A cable television (CATV) entry device includes an input port configured to be connected to a CATV network, a diplexer having a low pass terminal, a high pass terminal, and a common terminal. The low pass terminal is electrically connected to input port. The entry device includes a first port electrically connected to the common terminal, and a first splitter electrically connected to the high pass terminal. The entry device includes MoCA ports, each connected to an output terminal of the first splitter. The first splitter is configured to bidirectionally communicate MOCA signals between the MoCA ports. The diplexer and the first splitter are configured to bidirectionally communicate the MoCA signals between each of the MoCA ports and the first port. The diplexer is configured to prevent the MoCA signals from being communicated to the input port.
