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,

A Hotwire 5038 Distributed POTS Filter is installed on each telephone on the same

POTS line as DSL.

NOTES:

In this document:

— End-user system is used to represent any host with an Ethernet connection.

— 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.

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

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.

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.
