Before You Begin

The Hotwire5620 RTU (Remote Termination Unit) interoperates with the Hotwire

8510 DSL Card in the DSLAM (Digital Subscriber Line Access Multiplexer) system.

An optional POTS (Plain Old Telephone Service) splitter is available for the Hotwire

5620 RTU. When a POTS splitter is installed, the telephone and 5620 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:

Wiring and Cables Needed

The following wiring and standard connectors are used with this product:

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).

Standard RJ11 wall jack.

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

5620 RTU,

page 8, for Ethernet cable details.

Package Checklist

Verify that your package contains the following:

-Model 5620 Remote Termination Unit (RTU)

-DSL interface cable with RJ11 connectors

-Power cord with power transformer

-Two ferrite chokes

What Does the Hotwire RADSL RTU Do?

The Hotwire 5620 RTU is a component in the Hotwire DSL Access System. This

system provides high-speed Internet or corporate LAN access over traditional

twisted-pair copper telephone wiring.

A POTS splitter blocks out the DSL signal and allows 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:

HA Hotwire 5030 or 5038 POTS Splitter is installed near the demarcation point for all

telephones on the same POTS line as DSL,

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

POTS line as DSL.

DSL Access with a Hotwire 5030 or 5038 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).

The Hotwire 5030 POTS splitter is designed for outdoor or indoor installation. The

Hotwire 5038 POTS Splitter is designed for indoor use only.

When a Hotwire 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.

NOTES:

— End-user system is used to represent any PC with an Ethernet connection and

DSL-based service.

— Network Service Provider (NSP) is used to represent any Internet Service

Provider (ISP) or remote LAN access provider.

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.

!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 17.

2. Disconnect the DSL access pair from the local loop. A punchdown block is used

without a POTS splitter in the following example.

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.

RJ11 Wall Jack

The Hotwire 5620 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 wall jack.
