December 1998
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:

-
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:
H A Hotwire 5030 or 5038 POTS Splitter is installed near the demarcation point for all
telephones on the same POTS line as DSL,
H 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
or
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:
H From the demarcation point to the CP POTS splitter, and
H From 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
Instructions,
2. Disconnect the DSL access pair from the local loop. A punchdown block is used
without a POTS splitter in the following example.

Verify that the correct straight-through or crossover cable is
installed. Refer to
Check that the power cord is securely installed on both ends.
Installing the Hotwire 5620 RTU,
page 8.
If no LEDs are on, the power supply may be defective. Test the
outlet to verify power. If the problem persists, contact the NSP.
If other LEDs are on, the PWR LED may be burned out. Unplug
the unit and reapply power; watch all LEDs during the
power-on self-test to verify if the PWR LED is functioning.
TST LED is on. A test initiated by the NSP may be active. Wait five minutes.
If the TST LED does not go off, contact the NSP.
Increasing the Number of End-User Systems
A single PC is attached to the Hotwire 5620 RTU using an Ethernet crossover cable. To
increase the number of PCs, connect all PCs to an Ethernet hub using a
straight-through cable. The Hotwire 5620 RTU can support up to 32 PCs. V erify any
planned changes with the NSP.

4. Do not attempt to service this product yourself, as opening or removing covers
may expose you to dangerous high voltage points or other risks. Refer all servicing
to qualified service personnel.
5. General purpose cables are used with this product for connection to the network.
Special cables, which may be required by the regulatory inspection authority for
the installation site, are the responsibility of the customer. Use a UL Listed, CSA
certified, minimum No. 24 AWG line cord for connection to the Digital Subscriber
Line (DSL) network.
6. When installed in the final configuration, the product must comply with the
applicable Safety Standards and regulatory requirements of the country in which it
is installed. If necessary , consult with the appropriate regulatory agencies and
inspection authorities to ensure compliance.
7. A rare phenomenon can create a voltage potential between the earth grounds of
