What Does the Hotwire 5446 RTU Do?
The Hotwire5446 RTU (Remote Termination Unit) is a component in the Hotwire
RADSL Access System and interoperates with the Hotwire 8546 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 RADSL 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.

— Service provider is used to represent any Internet Service Provider (ISP) or
remote LAN access provider.
DSL Access without a POTS Splitter
When the Hotwire 5446 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 at the customer premises:
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 POTS Splitter is designed for indoor use only.

Package Checklist
Verify that your package contains the following:
Model 5446 Remote Termination Unit (RTU)
DSL interface cable with RJ11 modular plugs
Power cord with power transformer
Refer to
Cables & Connectors on page 14 for standard pin numbers.
Wiring and Cables You Need
The following wiring and standard connectors are used with this product:
Standard RJ11 wall jack.
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 8-pin, non-keyed modular plug for a PC or
workstation. An Ethernet straight-through or crossover cable is used. Refer to
Installing the Hotwire 5446 RTU on page 8 for Ethernet cable details.
After the RTU is installed and powered on, there are additional requirements in order to
utilize the DSL and Ethernet connections. Refer to
Hotwire 5446 RTU IP Setup on
page 13.

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 19.

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 5446 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.
