Foreword

The Alliance for Telecommunications Industry Solutions (ATIS) serves the public through improved understanding between carriers, customers, and manufacturers. The Packet Technologies and Systems Committee (PTSC) develops and recommends standards and technical reports related to services, architectures, and signaling, in addition to related subjects under consideration in other North American and international standards bodies. PTSC coordinates and develops standards and technical reports relevant to telecommunications networks in the U.S., reviews and prepares contributions on such matters for submission to U.S. ITU-T and U.S. ITU-T Study Groups or other standards organizations, and review for acceptability or per contra the positions of other countries in related standards development and takes or recommends appropriate actions.

The mandatory requirements are designated by the word shall and recommendations by the word should. Where both a mandatory requirement and a recommendation are specified for the same criterion, the recommendation represents a goal currently identifiable as having distinct compatibility or performance advantages.  The word may denotes an optional capability that could augment the standard. The standard is fully functional without the incorporation of this optional capability.

The communication of facts and ideas depends upon a mutual understanding of terminology. This is particularly true in the rapidly growing field of information technology, where there is a continuing need for a comprehensive source of agreed-upon technical terms and definitions.

This Glossary began as a 5800-entry, search-enabled hypertext telecommunications glossary titled Federal Standard 1037C, Glossary of Telecommunication Terms. Federal Standard 1037C was updated and matured into an American National Standard (ANS): T1.523-2001, Telecom Glossary 2000, under the aegis of ASC T1. In turn, T1.523-2001 has been revised and redesignated under the ATIS procedures for ANS development as ATIS-0100523.2011, ATIS Telecom Glossary 2011, and most recently ATIS-0100523.2019, ATIS Telecom Glossary 2019.

Future control of this document will reside with PTSC. This control of additions to the specification, such as protocol evolution, new applications, and operational requirements, will permit compatibility among U.S. networks. Such additions will be incorporated in an orderly manner with due consideration to the ITU-T layered model principles, conventions, and functional boundaries.

Suggestions for improvement of this document are welcome. They should be sent to the Alliance for Telecommunications Industry Solutions, Attention: PTSC, 1200 G Street NW, Suite 500, Washington, DC 20005.

At the time of consensus on this document, PTSC, which was responsible for its development, had the following leadership:

M. Dolly, PTSC Chair (AT&T)
V. Shaikh, PTSC Vice Chair (Perspecta Labs)
