FEATURES
• Low-cost, high-speed LAN and Internet
connections for home or business.
• Operates over existing copper lines—no
pricey T1 lines and no new installation
expenses.
• Switch-selectable data rates for highand low-bandwidth applications.
• Simple setup and little configuration
means no substantial training or
operating costs.
• 1U rack height saves cabinet space.
OVERVIEW
Our SDSL and IDSL Network Extenders provide home
users and businesses with dedicated digital Internet and
LAN connections over copper pairs. They’re ideal for use
in situations where the local network and the gateway
to the ISP aren’t close enough to be directly attached to
each other—places like campus-based businesses, multipleunit apartment buildings, and urban areas.
They work over the existing copper cables already installed
at your site. So you won’t be paying for new installations
or expensive T1 connections—and you don’t even have to
subscribe to DSL service! Because installation is simple and
the only thing you have to configure is the data rate, you
won’t incur extra training costs.
All models do symmetrical data transfer, which makes
them ideal for applications in which two network segments—
two clinics at a hospital, for instance—need to be able to send
and receive data at equally fast rates.
A broadcast-limiting feature ensures that broadcast traffic
only consumes up to 20% of the total bandwidth. However,
this only applies to pure broadcast traffic; unicast and
multicast traffic are guaranteed at least 80% of the available
bandwidth.
SDSL Network Extender 2000 and IDSL Network
Extender Kits
These kits—and the Extender 2000 is one too, even if it’s
not named that way—consist of a single-port provider unit
and a single-port subscriber unit. They create a point-to-point
digital link between two 10BASE-T Ethernet network
segments.
Both the 10BASE-T network interface and the unit-to-unit
DSL interface are carried on RJ-45 connectors.
IDSL Subscriber Unit
The LR0012A is a 1-port subscriber unit that connects to
our discontinued 12-port provider units with AC (LR0011A-AC)
or DC (LR0011A-DC) power.
The 12-to-1 configuration is intended for applications in
which high-speed LAN and Internet access are essential for
distributed local sites—an on-site office with various local
clients, for instance.
Data Rates
The SDSL and IDSL Network Extender Kits don’t require
software. In fact, they almost don’t require configuration
or control at all. The one exception is the data rate at which
they operate.
Each provider unit has one DIP switch that you can use to
control this function. At installation time, you can try the
highest available data rate, and if the provider and subscriber
units fail to link at that rate, just step down to the next and
try again. You can keep doing this until you reach a data rate
at which the units can communicate successfully.
For point-to-point applications that need plenty of
bandwidth, the SDSL Network Extender 2000 can transmit
data at any of eight rates from 272 kbps to 2.32 Mbps.
Even on 26 AWG cable, 2.32-Mbps data can be sent as far
as 11,300 feet (3444.2 m), and slower data can be sent
farther—up to 20,200 feet (6156.9 m) for 272 kbps.
The IDSL Network Extenders are designed for networks
that will send only a low volume of data across the DSL link.
You can set these extenders for either 128 or 144 kbps, which
is double the top V.90 modem speed and the equal or better
of ISDN. (Plus it’s all on your own equipment, so you don’t
have to pay—or depend on — the telco.) The extenders can
send and receive data at these rates across as much as 18,000
feet (5486.4 m) of cable, no matter what the cable’s wire
gauge is.

(Maximum) specification on the next page.

Recognize any of these situations?
• You wait more than 30 minutes to get through
to a vendor’s tech support.
• The so-called “tech” isn’t of much help to you.
• You don’t have a purchase order number and the
tech refuses to help you.
• It’s 9 p.m. and you need help, but your vendor’s
tech support line is closed.
According to a survey by Data Communications
magazine, 90% of network managers surveyed say
that getting the technical support they need is extremely
important when choosing a vendor. But even though
network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support
contract, the technical support and service they receive
falls far short of their expectations— and certainly isn’t
worth what they paid.
At Black Box, we guarantee the best value and the
best support. You can even consult our Technical Support
Experts before you buy if you need help selecting just
the right component for your application.
