What Does the HotWire RADSL RTU Do?
The 5446 RTU is a component in the DSL Access System. This system provides
high-speed Internet or corporate LAN access over traditional twisted-pair copper
telephone wiring.
DSL Access with a 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).
When a POTS splitter is used at both ends of the local loop, wiring is connected:
From the demarcation point to the CP POTS splitter, and
From the demarcation point to the DSL jack.
