CHAPTER 2: Introduction
2. Introduction
2.1 Overview
The Network Extenders convert either SDSL (Symmetrical Digital Subscriber
Line) or IDSL (ISDN Digital Subscriber Line) to Ethernet. This is a Layer 1
conversion, and Ethernet frames are then passed across the SDSL or IDSL link.
Each model’s function is described below.
• The LR0005A-KIT includes one Provider unit and one Subscriber unit, to
make one individual SDSL-to-Ethernet line.
• The LR0006A-AC/DC is a 12-port Provider unit with 12 individual SDSL-toEthernet ports to which you can attach 12 Subscriber units. No bridging or
routing is done internally.
• The LR0007A is a single SDSL-to-Ethernet Subscriber unit.
• The LR0010A-KIT includes one Provider unit and one Subscriber unit, to
make one individual IDSL-to-Ethernet line.
• The LR0011A-AC/DC is a 12-port Provider unit with 12 individual IDSL-toEthernet ports to which you can attach 12 Subscriber units. No bridging or
routing is done internally.
• The LR0012A is a single IDSL-to-Ethernet Subscriber unit.
The connection across the SDSL line may be at 272, 528, or 728 kbps or 1.168
Mbps in both directions. Connection across the IDSL line may either 144 or 128
kbps. Speed is selectable and determined by the Provider unit; the remote
Subscriber unit will determine its line speed through communication with the
Provider unit.
SDSL/IDSL technology is intended for use from the telephone company central
office across the local loop to the home or business, or may also be used in
multiple-dwelling-unit environments to provide high-speed, long-reach data service
over phone-grade copper cable up to 18,000 feet (5486 m). Distance is determined
by speed selection and cable grade.
The typical application for IDSL or SDSL technology is high-speed Internet access
or remote LAN access.

IDSL AND SDSL NETWORK EXTENDERS
2.2 Features
• Traffic Indicators — All units feature an LED that will steadily pulse (once per
second) when the SDSL or IDSL connection is operational and the unit is
receiving valid data packets or status packets from the SDSL or IDSL Network
Extender on the remote side of the link.
• Link Down Notification — Allows for alarm notification for the SDSL or IDSL
link to the Ethernet device to which the Provider unit is connected.
• Broadcast Limiting (IDSL and SDSL Subscriber Units Only) — Ensures that pure
broadcast traffic will only be allowed to consume up to 20% of the total SDSL
or IDSL bandwidth. Unicast and multicast traffic are guaranteed at least 80%
of the total SDSL or IDSL bandwidth.
• Local Traffic Filtering (IDSL and SDSL Provider and Subscriber Units) — The
units will build a database up to 255 MAC addresses and will provide traffic
filtering based on the learned MAC addresses. MAC addresses are learned
based on the Source Address of the Ethernet packets, and are filtered based
on the Destination Address of the Ethernet packets. Addresses are removed
from the filtering database if the unit does not receive traffic from that Source
for a 5-minute period, but are relearned once the unit receives packets from
that Source Address.
2.3 Selecting IDSL Bandwidth
For LR0010A-KIT, LR0011A-AC/DC, and LR0012A, Switch #2 on the Provider
Unit’s front panel controls the IDSL bandwidth. (Switch #1 is not used.)
If Switch 2 is in the up position, the IDSL connection will provide 128-kbps
symmetrical bandwidth. If Switch 2 is in the down position, the IDSL connection
will provide 144-kbps symmetrical bandwidth. There is no switch on the Subscriber
Unit; it will determine its speed through communication with the Provider Unit.

CHAPTER 2: Introduction
2.4 Selecting SDSL Bandwidth
For LR0005A-KIT, LR0006A-AC/DC, and LR0007A, two switches are used to select
the SDSL bandwidth for each SDSL/Ethernet port pairing. The table below shows
switch configurations and associated bandwidth and distance support (in feet).

CHAPTER 3: Installation
3. Installation
This chapter provides basic installation procedures. We strongly recommend using
proper static-protection techniques when installing and handling the equipment.
3.1 Installation for LR0005A-KIT, LR0007A, LR0010A-KIT, and LR0012A
NOTE
A Network Extender Subscriber Unit must be connected (via the DSL
line) to a Network Extender Provider. Two Subscriber Units cannot be
connected back-to-back.
1. Unpack the Network Extender and power supply.
2. Plug the power supply into both the power source and back of the unit. (It
doesn’t matter which order.) Verify that the Power LED is lit. On the IDSL
Network Extender and SDSL Network Extender Provider Units, the Lnk, Tx,
and Rx LEDs will also be lit.
3. Plug in the DSL connection (see the Appendix for SDSL connection pinout
information). On the Provider Units, verify that the switches on the back of the
unit are in the appropriate position (see below).
LR0010A-Kit (Provider Unit) Switch Configuration
Switch #1: Not used.
Switch #2
Bandwidth Distance (in feet)
Down 144 kbps 18,000
Up 128 kbps 18,000
LR0005A-Kit (Provider Unit) Switch Configuration
Distance Supported (in feet)
Switch #1 Switch #2 Bandwidth 26 AWG 24 AWG
Down Down 1.168 Mbps 9,000 12,000
Down Up 784 kbps 11,000 13,000
Up Down 528 kbps 13,000 15,000
Up Up 272 kbps 15,000 17,000
The IDSL and SDSL Subscriber Units (LR0010A-KIT, LR0012A, LR0005A-KIT,
LR0007A) do not use these switches.
14
IDSL AND SDSL NETWORK EXTENDERS
NOTE
The distance of the copper cable between the local Network Extender
and the remote Network Extender will affect the linking of the DSL
connection. If the distance is greater than a particular speed will
support, the units will not link up. Note that it may take anywhere
between 1 and 5 minutes for the DSL connection to link up, depending
on cable quality and distance.
4. Verify the DSL connection via the DSL LED on the front of the unit. A steadily
pulsing LED (once per second) indicates that the DSL connection is established
and operational. On the Network Extender Provider Units, the Lnk, Tx, and Rx
LEDs will not be lit once the DSL link is operational.
5. Plug in the local Ethernet connection and verify physical link by the Lnk LED
on the front of the unit. See the Appendix for Ethernet connection pinout
information.
Once the units have established both DSL and Ethernet link on both sides of the
connection, normal data communication will flow through the units, essentially
providing a very long Ethernet connection at DSL speeds.
3.2 Installation for LR0006A-AC/DC and LR0011A-AC/DC
1. Unpack the Network Extender and power cord (AC only). Attach the included
rubber feet for stackable installations or attach rackmount brackets and mount
the Network Extender in an equipment rack. When mounting unit in an
equipment rack, please adhere to the following:
a. Maximum recommended ambient temperature is 86°F (30°C). Internal
temperatures of rack should be considered for continued safe operation.
b. Do not block power-supply vents or otherwise restrict airflow when installing
unit in rack.
c. Mechanical loading of rack should be considered so that the rack remains
stable and unlikely to tip over.
d. Consideration of the overall loading of the branch circuit should be given
before installing any equipment in a rack environment.
e. Make sure that a reliable grounding path is maintained in the rack system.
This unit is intended for a grounded connection.
15
CHAPTER 3: Installation
2. For AC units, plug the power cord into both the power source and the back of
the unit. (It doesn’t matter which order.) For DC units, attach the DC power
leads and ground connection to the appropriate terminals indicated on the
back of the unit and supply power to the unit. Verify that the Power LED is lit.
Until the DSL link is established, the Lnk, Tx, and Rx LEDs will also be lit on
each port. When the DSL link has been established, the Tx and Rx LEDs will
function normally, indicating activity on the Ethernet segment.
3. Attach the RJ-21 connector/cable to the DSL connector on the unit. This
connection is typically made to a punchdown block for copper wire cross
connects in a telco office/room, or with an RJ-21 to RJ-45 breakout cable (see
the Appendix for SDSL connection pinout information).
4. Verify that the switches on the front of the unit are in the appropriate position
for each port (see below).

Up Down 528 kbps 13,000 15,000
Up Up 272 kbps 15,000 17,000
NOTE
The distance of the copper cable between the local Network Extender
and the remote Network Extender will affect the linking of the DSL
connection. If the distance is greater than a particular speed will
support, the units will not link up. Additionally, it may take anywhere
between 1 and 5 minutes for the DSL connection to link up, depending
on cable quality and distance.
16
IDSL AND SDSL NETWORK EXTENDERS
5. Verify the DSL connection via the DSL LED on the front of the unit. A steadily
pulsing LED (once per second) indicates that the DSL connection is established
and operational.
6. Connect the local RJ-21 Ethernet connector/cable to network equipment (such
as an Ethernet switch) and verify physical link by the Lnk LED on the front of
the unit. See the Appendix for Ethernet connection pinout information.
NOTE
The Network Extender Provider Units do not present Ethernet link (Lnk)
to the Ethernet network equipment if the DSL connection is not present.
This feature allows for remote monitoring of the DSL line by simply
monitoring the Ethernet port for link status.
Once the units have established both DSL and Ethernet link on both sides of the
connection, normal data communication will flow through the units, essentially
providing a very long Ethernet connection at DSL speeds.
