Overview

Introduction

To obtain faster rates and precise data, equipment must be able to transmit
digitally. Like Primary Rate Interface (PRI), BRI is a standard protocol for
accessing Integrated Services Digital Network (ISDN) services. By using BRI,
the MERLIN LEGEND Communications System can connect with the speed and
accuracy of ISDN services.
BRI lines offer the capability of voice, high-speed data, local area network
(LAN) interconnection, and video transmission (see Figure 1-1). In addition to
the standard features offered by other releases of the MERLIN LEGEND
Communications System, the MERLIN LEGEND BRI system offers the ability to
subscribe to several BRI features. Other BRI features have applications specific
to Federal Government telephone networks.

NOTE:
The MERLIN LEGEND system does not support BRI when the MERLIN LEGEND
BRI lines are shared by ISDN stations outside the system. "Shared" means that
the same lines are connected to more than one station.
