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).

3
When a 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.

Installing the DSL Access Wiring
The local loop terminates at the punchdown block or NID. Wiring must be connected
from the customer premises side of the punchdown block or the NID to the DSL jack.
Typically, the punchdown block is installed in commercial locations and the NID is
installed in residential locations.
"Procedure
1. Access the punchdown block or NID. Disconnect the DSL access pair from the
local loop.
!WARNING:
Do not continue unless the DSL access line from the local loop has been
disconnected at the NID or punchdown block. Refer to Important Safety
Instructions,
page 16.

DSL Jack Installation
The 5216 RTU connects to the local loop via wiring from the demarcation point to an
RJ11 wall jack. The DSL twisted-pair wiring from the local loop terminates at a new or
existing wall jack. It may be necessary to install a standard single RJ11 jack or replace
a single jack with a double RJ11 jack.
The RJ11 6-pin jack uses the center two pins. For pin assignments, refer to
Cables &
Connectors , page 13.

4. Do not attempt to service this product yourself, as opening or removing covers
may expose you to dangerous high voltage points or other risks. Refer all servicing
to qualified service personnel.
5. General purpose cables are used with this product for connection to the network.
Special cables, which may be required by the regulatory inspection authority for
the installation site, are the responsibility of the customer. Use a UL Listed, CSA
certified, minimum No. 24 AWG line cord for connection to the Digital Subscriber
Line (DSL) network.
6. When installed in the final configuration, the product must comply with the
applicable Safety Standards and regulatory requirements of the country in which it
is installed. If necessary, consult with the appropriate regulatory agencies and
inspection authorities to ensure compliance.
7. A rare phenomenon can create a voltage potential between the earth grounds of
two or more buildings. If products installed in separate buildings are
interconnected, the voltage potential may cause a hazardous condition. Consult a
qualified electrical consultant to determine whether or not this phenomenon exists
and, if necessary, implement corrective action prior to interconnecting the products.
8. Input power to this product must be provided by one of the following: (1) a UL
Listed/CSA certified power source with a Class 2 or Limited Power Source (LPS)
output for use in North America, or (2) a certified transformer, with a Safety Extra
Low Voltage (SELV) output having a maximum 240 VA available, for use in the
country of installation.
9. In addition, since the equipment is to be used with telecommunications circuits,
take the following precautions:
— Never install telephone wiring during a lightning storm.
— Never install telephone jacks in wet locations unless the jack is specifically
designed for wet locations.
— Never touch uninsulated telephone wires or terminals unless the telephone
line has been disconnected at the network interface.
— Use caution when installing or modifying telephone lines.
— Avoid using a telephone (other than a cordless type) during an electrical
storm. There may be a remote risk of electric shock from lightning.
— Do not use the telephone to report a gas leak in the vicinity of the leak.
