What Does the 5038 Distributed POTS Splitter Do?
The 5038 Distributed 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 blocks out the DSL signal and allows the POTS frequencies to pass
through. At the customer premises, the RADSL RTU and telephone can function
simultaneously over the same pair of copper wires when a POTS splitter is used for the
RTU and each telephone on the same POTS line.
Copper pairs run from the central office (CO) to the customer premises (CP) to create
the local loop. The local loop terminates on the customer premises.

NOTES:
— The RTU network performance will depend on the quality and condition of the
phone wiring to and inside the customer premises.
— Telephone is used to represent any equipment that plugs into a phone jack
and uses the POTS phone line, such as a phone, modem, or fax machine.
— A distributed POTS splitter is required for every phone outlet that has
telephone equipment attached.
