SDSL and IDSL Network Extenders

Use fast, flexible SDSL or IDSL to extend your Ethernet network.


Low-cost,high-speedLAN and Internet connections for home or business.

Operates over existing copper lines—nopricey T1 lines and no new installation expenses.

Switch-selectabledata rates for highandlow-bandwidthapplications.

Simple setup and little configuration means no substantial training or operating costs.

1U rack height saves cabinet space.


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—placeslikecampus-basedbusinesses, 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—andyou 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—needto be able to send and receive data at equally fast rates.

A broadcast-limitingfeature 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—andthe Extender 2000 is one too, even if it’s not named thatway—consistof asingle-portprovider unit and asingle-portsubscriber unit. They create apoint-to-pointdigital link between two10BASE-TEthernet network segments.

Both the 10BASE-Tnetwork interface and theunit-to-unitDSL interface are carried onRJ-45connectors.

IDSL Subscriber Unit

The LR0012A is a 1-portsubscriber unit that connects to our discontinued12-portprovider units with AC(LR0011A-AC)or DC(LR0011A-DC)power.

The 12-to-1configuration is intended for applications in whichhigh-speedLAN and Internet access are essential for distributed localsites—anon-siteoffice 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-pointapplications 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-Mbpsdata can be sent as far as 11,300 feet (3444.2 m), and slower data can be sentfarther—upto 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—ordependon—thetelco.) 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.

Why Buy From Black Box?

Exceptional Value. Exceptional

Tech Support. Period.

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—andcertainly 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.

Don’t waste time and money—callBlack Box today.
