Section 2 - Installation Installation Planning Overview The proper cable installation, placement of filter/amplifier, frequency planning and home preparation for signal coexistence should be planned out thoroughly before deploying the DXN-220. Inadequate planning will not only affect the DXN-220 network but also cause unwanted interference with other existing services. The following section discusses these installation considerations in more detail. Proper Cable Installation The rooms qualified to be part of the DXN-220 network should have an existing coaxial connection and the following characteristics: • The room is capable of receiving good quality analog television service (no set-top box required) over the coaxial cable. • The room is capable of receiving digital television services using a set-top box. If the room cannot receive digital or good quality analog television services, the Ethernet-Coaxial network capabilities may be compromised to this location. Amplifier Bypassing An electronic amplifier is a device that boosts a weak signal. The typical amplifier cannot pass DXN-220 network signal because they are designed to be unidirectional devices. Hence, the amplifier should be uninstalled or bypassed if possible. To bypass an amplifier, user will need to install Diplexers to separate the DXN-220 signal and other signal first and only install the amplifier between the paths of none DXN-220 network signal.
