Scope and purpose

This standard is one of a series that defines and describes supplementary services. These services may be made available for users with non-ISDN interfaces who access SS7 capable networks and also within the context of an Integrated Services Digital Network (ISDN). This standard describes Calling Name Identification Restriction, which is an originating service that allows a user to alter the network stored or subscribed privacy status associated with the user's Calling Name. The associated switching and signaling specifications are also provided. This service may be made available on demand or in a subscription arrangement. The interaction of this service with other service capabilities defined in American National Standards is also included. The purpose of this standard is to allow maximum compatibility among network and user owned telecommunications equipment in order to increase the attractiveness and usefulness of the additional information transfer capabilities of SS7 and ISDN-based capabilities. When more than one network is involved in the provision of network capabilities or service specified in this standard, bilateral agreements among the networks involved may be required. Such agreements are outside the scope of this standard.

Application

This standard applies to non-ISDN user-network interfaces, ISDN Basic Rate Interfaces and Primary Rate Interfaces. The non-ISDN user-network interfaces are the analog or equivalent digital interfaces specified in American National Standard for Private Branch Exchange (PBX) Switching Equipment for Voiceband Applications, ANSI/EIA/TIA 464-A-1989 and supplement ANSI/EIA/TIA 464-A-1-1992, American National Standard for Telecommunications - Digital Subscriber Signalling Systme No. 1 (DSS1) - Layer 3 Overview, ANSI T1.615-1992, and American National Standard for Telecommunications - Interface between carriers and customer installations - Analog voicegrade switched access lines using loop-start and ground-start signaling, ANSI T1.401-1993. For ISDN, this standard is intended to supplement the Basic Circuit Mode call procedures described in American National Standard for Telecommunications - Integrated Services Digital Network (ISDN) - Layer 3 signalling specification for circuit switched bearer services for Digital Subscriber Signaling Number 1 (DSS1), ANSI T1.607-1990, and American National Standard for Telecommunications - Signalling System No. 7 (SS7) - Integrated Services Digital Network (ISDN) User Part, ANSI T1.113-1995. It should be used in conjunction with the other American National standards for non-ISDN and ISDN supplementary services for a complete understanding of the interactions between this and other services. For ISDN, this supplementary service is applicable to the Speech, Voice- Band Data (3.1 kHz audio), and Data (64 kbit/s unrestricted) Circuit-Mode bearer services identified in American National Standard for Telecommunications - Integated Services Digital Network (ISDN) - Circuit Mode Bearer Service Category Description, ANSI T1.620-1991.
