What Does the POTS Splitter Do?
The POTS splitter and HotWire Remote Termination Unit (RTU) are components in the
RADSL Access System. This system provides high-speed Internet or corporate LAN
access over traditional twisted-pair copper telephone wiring.
The POTS splitter filters out the DSL signal and allows the POTS frequencies to pass
through. The RADSL RTU and telephone can function simultaneously over the same
pair of copper wires at the customer premises when a POTS splitter is used at both
ends of the local loop.
Copper pairs run from the central office to the customer premises to create the local
loop. The local loop terminates on the customer premises at the demarcation point in a
punchdown block or NID.
Wiring is connected from the demarcation point to the POTS splitter and to the DSL
jack. Wiring also connects the demarcation point to an RJ11 wall jack for DSL access
by the RTU.

When mounted outside, the POTS splitter must be installed at or above the height of
the NID, and should be a minimum of three feet above ground.
At the front of the housing, align the housing to open from the right with the rubber
grommet for cable access facing downward. Place the housing upright as shown. Use a
Phillips-head or combination Phillips/slotted-head screwdriver and the screws included
in the package.
