What Does the Hotwire 5030 POTS Splitter Do?
The Hotwire 5030 POTS Splitter and Hotwire endpoints are components in the
Hotwire RADSL Access System. This system provides high-speed Internet or corporate
LAN access over traditional twisted-pair copper telephone wiring.
The POTS (plain old telephone service) splitter blocks out the DSL (Digital Subscriber
Line) signal and allows the POTS frequencies to pass through. At the customer
premises, the RADSL (Rate Adaptive Digital Subscriber Line) endpoint and telephone
can function simultaneously over the same pair of copper wires 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 (network interface device). Wiring is connected from the
demarcation point to the customer premises POTS splitter and to the DSL jack.
