Before You Begin
An optional POTS (Plain Old Telephone Service) splitter is available for the 5216 RTU.
When a POTS splitter is installed, the telephone and 5216 RADSL (Rate Adaptive
Digital Subscriber Line) RTU can function at the same time over the same pair of
copper wires. In order to confirm the RTU installation, the POTS splitter should be
installed first.
To install a POTS splitter, refer to the appropriate POTS splitter document:

What Does the Hotwire RTU Do?
The 5216 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:
H From the demarcation point to the CP POTS splitter, and
H From the demarcation point to the DSL jack.
