Hotwire 5620 RTU Overview
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).

—Service provider is used to represent any Internet Service Provider (ISP) or
remote LAN access provider.
DSL Access with a Hotwire 5030 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 Hotwire 5620 RTU and a telephone can function simultaneously over the same pair
of copper wires when a Hotwire 5030 POTS Splitter is installed near the demarcation
point for all telephones on the same POTS line as DSL.
When a Hotwire 5030 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.

DSL Access without a POTS Splitter
When the Hotwire 5620 RTU is installed without a POTS splitter, the DSL line is used for
data only and does not provide telephone services.
Phone Filters
For optimum performance, if the wiring for the RTU is also used for voice (POTS), a
phone filter should be installed on each voice line with a phone, modem, fax machine, or
other telecommunications device attached. One Hotwire phone filter can be used with
multiple telecommunications devices (for example, a phone and fax machine can be
supported using a single filter) if a multiple line adapter is used.

There are two Hotwire phone filters that can be used with the 5620 RTU:
 Hotwire 6035 Universal Phone Filter is designed for use with a tabletop phone.
 Hotwire 6040 Universal Wall Jack Phone Filter is designed for use with a
wall phone.
If installing the router on the wall instead of a table or desk, refer to
Optional RTU Wall
Placement
on page 17 before installing the router and cables.

Getting Started
Before beginning your RTU’s installation, make sure that you have all the equipment you
will need.
Package Checklist
In addition to these instructions, verify that your package contains the following:
❑Model 5620 Remote Termination Unit (RTU)
❑DSL interface cable with RJ11 modular plugs
❑Power cord with power transformer
Wiring and Connectors You Will Need
The following wiring and standard connectors are used with this product:
❑Standard RJ11 wall jack for the DSL cabling.
❑Multiple line adapter if a telephone and RTU are connected in the same location.
❑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
procedures in
Installing the Hotwire 5620 RTU on page 9 for Ethernet cable details.
Refer to
Cables & Connectors on page 15 for standard pin numbers.

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 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.

Connecting to the DSL Access Wiring
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 localloop terminates at anew
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.
Procedure
1. Wiring can be run from the
punchdown block or NID to
a new or existing wall jack.
Match the pair colors on both
ends.
2. Label the DSL jack.
3. Reconnect the DSL access pair
at the punchdown block or NID.
Refer to
Installing the DSL
Access Wiring
on page 6.
Tighten both terminal screws
with a flat-blade screwdriver.
The RJ11 6-pin jack uses the center two pins. For pin assignments, refer to
Cables &
Connectors on page 15.
