ABSTRACT: This document provides the Telcordia view of generic requirements for Default Service for Integrated Services Digital Network (ISDN)
Basic Rate Interfaces (BRIs). Default Service provides a minimum level of service capabilities for both "new" and "existing" BRI lines.
This document explains the need for Default Service, what functionality needs to be provided, and how that can be achieved using
Telcordia requirements. This document provides information to the Local Exchange Carriers (LECs) to understand how an access line
should be provisioned to provide Default Service. At a minimum, Default Service is intended to be used by LEC personnel to assist them
during the installation process. Default Service can be expanded in the provisioning process so that LEC customers with voice
terminals can call emergency, LEC repair, or customer service numbers.
