Chapter 1 — ISDN Basic Rate Interface

Introduction

ISDN Overview

This chapter gives an overview of Integrated Services Digital Network
(ISDN) Basic Rate Interface (BRI).
Note: This document is intended to support the Meridian 1 Option 11
(sometimes referred to simply as the Option 11) system. (When only the
term "Meridian 1" is referenced, it is meant to include all members of the
Meridian 1 family (Meridian 1 Option 11 through Option 81C).
Integrated Services Digital Network (ISDN) is a global networking strategy
that provides an intelligent, universal network for voice and data
communications. ISDN is a set of international standards that define the next
generation of digital networking services.
Some of the benefits of ISDN are as follows:
— faster, more accurate, noise-free transmission, as well as greater security
and reliability
— ability to carry multiple information types, including speech, data,
image, and video
— standard interfaces to allow multi-vendor compatibility
— configuration flexibility when combining public and private networking
facilities.
ISDN differs from traditional communication in that it uses "out of band"
signaling. Signaling information is sent and received on a dedicated channel,
called a D-channel, leaving the remaining channels, called B-channels, free
for voice and data.
