What Does the Hotwire 5620 RTU Do?

The Hotwire 5620 RTU (Remote Termination Unit) is a component in the Hotwire
RADSL Access System and interoperates with the Hotwire 8373, 8374, or 8510 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 5620 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.

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 .

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 RJ1 1 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

Instructions

A punchdown block is used without a POTS splitter in the following example.

Connecting to the DSL Access Wiring

The Hotwire 5620 RTU connects to the local loop via wiring from the demarcation point
to an RJ1 1 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 RJ1 1 jack.
