What Does the Hotwire 5446 RTU Do?

The Hotwire 5446 RTU is a component in the Hotwire RADSL Access System. This system provides high-speed Internet or corporate LAN access over traditional twisted-pair copper telephone wiring.

A POTS splitter blocks out the DSL signal and allows the POTS frequencies to pass through. At the customer premises, the RADSL RTU and a telephone can function simultaneously over the same pair of copper wires when either:

HA Hotwire 5030 or 5038 POTS Splitter is installed near the demarcation point for all telephones on the same POTS line as DSL, or

HA Hotwire 5038 Distributed POTS Filter is installed on each telephone on the same POTS line as DSL.

DSL Access with a Hotwire 5030 or 5038 POTS Splitter

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 at the demarcation point in a punchdown block or network interface device (NID).

The Hotwire 5030 POTS splitter is designed for outdoor or indoor installation. The Hotwire 5038 POTS Splitter is designed for indoor use only.

When a Hotwire POTS splitter is used at both ends of the local loop, wiring is connected:

HFrom the demarcation point to the CP POTS splitter, and

HFrom the demarcation point to the DSL jack.
