A.1 Legend And Key to Source Citations
|[ ] (no source citation)||These definitions are from two major sources:
(a) FED-STD 1037C 1996, Glossary of Telecommunication Terms, and
(b) a body of definitions proposed and reviewed by industry standards workers.
|[After…]||Definitions with a source citation “[After…]” (as in “[After Weik ’89]”) are the responsibility of the Ad Hoc group editing the glossary rather than the responsibility of the authors of the cited material.|
|2196||Definitions extracted verbatim from MIL-STD-2196 (SH), Glossary, Fiber Optics (Jan. 1989). The citation “[After 2196]” indicates editing of the source definition. All such editing is the responsibility of the editors of this T1 standard and not the cited document.|

|CCITT/CCIR or ITU-T/ITU-R||Recommendations and other documents from the ITU-T and ITU-R, formerly the Consultative Committee for Telegraph and Telephone, and the Consultative Committee for Radio. The “CCITT” and “CCIR” labels are retained in this glossary in some cases because some of the cited documents have not been reissued and given a new name. In other cases, the more current “ITU-T” or “ITU-R” label is used for consistency within this glossary, even though the “CCITT” or “CCIR” label may be more formally accurate. This dual-citation approach is used because some definitions in this glossary are based on a harmonization of several closely related standards reflecting a broad context of different standards groups, and other definitions refer to specific international standards.|
|47CFR …||Definitions extracted verbatim from the Code of Federal Regulations, Sec. 47, Telecommunications (rev. Oct. 1, 1987, Oct. 1988 & ff.). Caution: Users of this standard are cautioned that-in cases where term names or definitions have been extracted verbatim from sources embedded in law, (e.g., Title 47,Code of Federal Regulations, [47CFR], or international treaty) in those cases, the wording of these legal definitions may have changed in the source documents [e.g., by legislative action] after this T1 standard was sent to press. To be absolutely up to date, the user is advised to examine the most recent of these legislative or treaty source documents.|
