Introduction
This chapter describes the principle features of the ONline 10BASE-T
Security Module.
The ONline 10BASE-T Security Module
The ONline 10BASE-T Security Module is a 12-port IEEE 802.3 repeater
module that complies with the 10BASE-T standard. The module is designed
for use with the 3Com ONline System Concentrators using unshielded
twisted pair wiring. The Security Module provides the following features
and benefits:
❑ Provides jamming security for 12 10BASE-T ports
❑ Provides security from unauthorized transmissions
❑ Uses the 3Com ONguard™ technology to secure the network from
eavesdropping and intrusions
❑ Supports up to 150 meter link distances on 22 gauge wire and up to
125 meters on 24 gauge wire (the meter distance on 26 gauge wire
varies by cable type)
❑ Complies fully with the 10BASE-T signaling standard
