INTRODUCTION
Thank you for purchasing these outstanding Black Box communication products. This user’s guide
describes how to operate your new Multi-rate Symmetric Digital Subscriber Line (MSDSL) devices.
Instructions for installing your DSL LAN Extender devices are described in the Installation section, while
the remaining sections review operation of the DSL LAN Extender devices after they are installed, such
as self-test, LED indication, and troubleshooting.
PRODUCT DESCRIPTION
The DSL LAN Extender 200 is an Ethernet bridge which utilizes Multi-rate Symmetrical Digital
Subscriber Line (MSDSL) technology to achieve a symmetrical transmission rate up to 2.3 Mbps in both
directions over a single copper telephone pair out to 5.5 miles/8.8 Km. The speed is dependent on the line
conditions and signal quality. Multi-rate SDSL allows users to select a fractional transmission rate to
optimize the length and line condition of the telephone pair used for a better Bit Error Rate (BER).
The DSL LAN Extender 200 was designed for remote LAN interconnection and high-speed Internet
access. This bridge has a 10Base-T Ethernet port and MSDSL line interface which can achieve high
transmission quality comparable to fiber optic BER without repeaters, up to 5.5 miles/8.8 Km. Featuring a
compact design for easy installation and combining its high-speed symmetrical rate and longer local loop
reach, a DSL LAN Extender 200 is an ideal solution for campus networks, remote LAN interconnection
and high-speed Internet access for businesses and consumers.
