HIGH-SPEED NETWORK MODEM

1.0 XL-12000B Product Overview

The XL-12000B modem is a high-speed, SDSL (Symmetrical
Digital Subscriber Line) point-to-point modem created to extend
Local Area Networks (LANs) up to 12,000 feet using ordinary
telephone wires. The modem uses Digital Subscriber Line (DSL)
transmission technology to deliver data at 2 Mbps.

The XL-12000B is designed for easy installation. Front panel LEDs
provide status and operational information. The modem is ideally
suited for connecting LANs in a campus environment where LANs
may be spread out over two miles. The XL-12000B units function
as a pair; one as Master and the other as Slave. The XL-12000B will
function as a bridge using Spanning Tree Protocol (STP) connecting
two independent segments. This mode allows the modem to pass
both IP and non-IP packets transparently making the segments a
single network. Examples of non-IP packets include Novell’s IPX
and Apple’s AppleTalkTM.
