What Does the Hotwire 6371 RADSL Router Do?
The Hotwire6371 Rate Adaptive DSL (RADSL) Router is a component in the Hotwire
Digital Subscriber Line (DSL) Access System and interoperates with the Hotwire 8373,
8374, and 8510 RADSL cards in the Digital Subscriber Line Access Multiplexer
(DSLAM) system.
The 6371 router operates as an IP router connecting a DSL link to an Ethernet network
to provide high-speed Internet or corporate LAN access over traditional twisted-pair
copper telephone wiring. Copper pairs run from the central office to the customer
premises 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 allows the POTS frequencies to pass through. At the customer
premises, the DSL router 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 6371 RADSL Router 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 Distributed POTS Splitter is designed for indoor use only.

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: New or existing shielded twisted-pair wiring (CAT5 or better). The
CAT5 wiring must meet EIA/TIA-568 specifications with 24 AWG (.5 mm) or
26 AWG (.4 mm). A straight-through or crossover Ethernet cable is used.
Refer to
Installing the Hotwire 6371 RADSL Router on page 8 for cabling details.
Optional Cable
The Hotwire 6371 RADSL Router is typically configured remotely by the Service
Provider. The following optional cabling and adapter are only used with this product to
configure the router locally:
-Console cabling: Straight-through cable with 8-pin non-keyed modular plugs
(Part No. 035-0276-1431)
-Console adapter:
— 8-pin modular to DB9 adapter plug (Part No. 002-0093-0031),
or
— A configurable RJ to DB9 adapter wired as shown in Cables & Connectors on
page 14.
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 20.
A punchdown block is shown without POTS in the following example.

Connecting to the DSL Access Wiring
The Hotwire 6371 RADSL Router 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.
