Basic Rate Interface (BRI) Provisioning Guide
This section describes the line and feature parameters that must be provisioned at the
central office for basic connectivity and for additional calling capabilities provided
by optional BRI features.
Introduction
The MERLIN LEGEND
®
BRI system is designed to operate with 5ESS Generic 8 (or 9)
Custom BRI central office switches. The system presents a U-interface and works with 2
binary. 1 Quarternary (2B1Q) line coded Integrated Services Digital Network (ISDN) BRI
lines.
The service on each BRI line is specified in a User Service Order Profile (USOP), which is
configured on the 5ESS central office at subscription time. The USOP contains
information necessary for the 5ESS to provide service to each station connected to
the system. Each USOP is identified by a Service Profile Identifier (SPID).
