Welcome to the Cabletron Systems CyberSWITCH 100 Family Advanced User Information
Guide
. This guide provides hardware specifications for the CyberSWITCH 100 family of products

ISDN Overview
ISDN provides an inexpensive switched digital access to remote sites. The ISDN BRI standard
provides for two high speed 64 K bits per seconds (Kbps) bearer channels used for voice or data
connections and one 16 Kbps signaling data (D) channel used for call setup, signaling and other
information. ISDN allows all types of information to be transmitted including voice, data, fax and
video. Multiple devices can be linked to a single ISDN connection, each having its own telephone
number. Two or more channels can be combined into a single larger transmission pipe offering
variable transmission speeds.
