Section 2 - Installation Cable Television (CATV) For a cable television subscriber, there are no additional components required to work with the DXN-220 on the same cable network. The user may choose to install the DXN-220 on the network and use it as-is if data rate is acceptable. Else, user may improve DXN-220 network performance by inserting a Low Pass Filter (LPF-860Mhz) at Point of Entry (POE) where the drop cable enters the house. DBS Satellite Television with Terrestrial Television (Off-Air) The Direct Broadcast Satellite (DBS) uses proprietary satellite channel-stacking switch or Low-Noise Block (LNB) to distribute the resulting signal (usually 950 to 2150 MHz) in the same cable network that carries the lower-frequency terrestrial television from an outdoor antenna. Another Diplexer then separates the signals to the receiver of the TV set and the DBS set-top box (STB). Most of the satellite switches are not designed to pass DXN-220 network signal and prevents it from forming a network. It is recommended that satellite signal and DXN-220 network signal should remain on separate cable networks. If separate wiring cannot be done, then additional components have to be installed: 1. Install Triplexer to separate UHF/VHF, DXN-220, and DBS signals. 2. Install MoCA Coupler switch before the satellite switch. Existing OSP installed MoCA network The DXN-220 will automatically scan for an available channel and form Ethernet-Coaxial network. This may cause issue with the existing OSP MoCA network. It will not be permitted to join the OSP MoCA network unless utilizing the same frequency and password. The remedy in this situation is to use the DXN-220 software utility to configure the DXN-220 to be on the same frequency with the same privacy network as the existing OSP MoCA network.
