What Does the Hotwire 5216 RTU Do?
The Hotwire5216 RTU (Remote Termination Unit) is a component in the Hotwire
RADSL Access System and interoperates with the Hotwire 8540 DSL Card in the
DSLAM (Digital Subscriber Line Access Multiplexer) system. This system provides
high-speed Internet or corporate LAN access over traditional twisted-pair copper
telephone wiring.
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).
Optional POTS Splitter
An optional POTS (plain old telephone service) splitter can be installed to block out the
DSL signal and allow the POTS frequencies to pass through. At the customer
premises, the 5216 RTU and a telephone can function simultaneously over the same
pair of copper wires when either:
A Hotwire 5030 or 5038 POTS Splitter is installed near the demarcation point for all
telephones on the same POTS line as DSL,
or
A Hotwire 5038 Distributed POTS Filter is installed on each telephone on the same
POTS line as DSL.

DSL Access without a POTS Splitter
When the Hotwire 5216 RTU is installed without a POTS splitter, the DSL line is used
for data only and does not provide telephone services.

DSL Access with a Hotwire 5030 or 5038 POTS Splitter
When a Hotwire 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.
The Hotwire 5030 POTS splitter is designed for outdoor or indoor installation. The
Hotwire 5038 Distributed POTS Splitter is designed for indoor use only.

Package Checklist
Verify that your package contains the following:
Model 5216 Remote Termination Unit (RTU)
DSL interface cable with RJ11 modular plugs
Power cord with power transformer
Wiring and Cables You Need
The following wiring and standard connectors are used with this product:
Standard RJ11 wall jack for the DSL cabling.
DSL cabling: New or existing unshielded twisted-pair wiring (CAT3 or better). The
CAT3 wiring must meet EIA/TIA-568 specifications with 24 AWG (.5 mm) or
26 AWG (.4 mm).
Ethernet cabling: Standard Ethernet crossover cable with an 8-pin, non-keyed
modular plug for a PC or workstation. Refer to
Installing the Hotwire 5216 RTU on
page 8 for Ethernet cable details.
Refer to Cables & Connectors on page 12 for standard pin numbers.

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 an RJ11 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.
2. 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
on page 16.

3. Locate the DSL pair of T1/R1 connectors on the customer premises side of the
NID or punchdown block. Attach the wiring that will be connected to the DSL jack.
In the following example, a NID is used without a POTS splitter. It includes an
existing POTS line and a second pair installed for DSL access.

Connecting to the DSL Access Wiring
The Hotwire 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.
