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.
