1. INTRODUCTION

This guide is intended for the system or network administrator
responsible for installing and monitoring a TRANSITION Networks
Model 1004 12-Port Ethernet™ Repeater Hub. A working knowledge of
local area network (LAN) operations, including familiarity with
communications protocols used on interconnected LANs, is assumed.

The Model 1004 Repeater Hub

The TRANSITION Networks Model 1004 12-Port Ethernet™ Repeater
Hub, is a small, multi-purpose Ethernet repeater that is site-
configurable, using an optional Slide In Card (SIC), for various signal
transmission media.

Twelve fixed RJ-45 twisted-pair connectors 

SICs, if installed, provide fiber optic, male and female AUI,
BNC, or RJ-45 connectors.

SICs allow future network expansion or modification
