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.

Frequency Planning
The DXN-220 is capable of operating between frequency bands of 800MHz and 1500MHz. In order to avoid interference
between the DXN-220 device and other devices on the same cable network, DXN-220 device must operate at a
frequency spectrum that is different from other devices.
• 5-42MHz (High-speed Internet Access Upstream)
• 42-850MHz (High-speed Internet Access downstream)
• 50-806MHz (Off-Air TV)
• 50-860MHz (Cable TV)
• 950-2150MHz (Satellite L-Band)
One common scenario is where DXN-220, cable television and high-speed Internet service need to coexist.
The cable television in United States operates between 50-860MHz while high-speed Internet service upstream
and downstream operate between 5-42MHz and 42-850 MHz respectively. Hence, the logical choice for
DXN-220 frequency would be between 940-1500MHz. Similar frequency planning approach should be taken into
consideration when dealing with Satellite and off-air antenna.
Terrestrial Television (Off-Air)
If you are receiving terrestrial television service using a broadband antenna, then additional components may have
to be installed in order to be compliant with governmental regulations. DXN-220 network signals operating in the 800
to 1500 MHz range should be prevented from radiating out of the antenna by using a small, in-line Low Pass Filter
(LPF-860Mhz). This filter will prevent DXN-220 network signals from reaching the antenna.

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.
