This document provides Federal departments and agencies a comprehensive source of definitions of terms used in telecommunications and directly related fields by international and U.S. Government telecommunications specialists.
As a publication of the U.S. Government, prepared by an agency of the U.S. Government, it appears to be mostly available as a public domain resource, but a few items are derived from copyrighted sources: where this is the case, there is an attribution to the source.
A substantial number of non-trivial 1037C articles are now incorporated into Wikipedia; insubstantial articles, and articles which contain copyrighted material, should not be copied into Wikipedia.
Note: please do not copy any definitions from Federal Standard 1037C with attribution to non-Federal sources such as NATO, CCITT, the Radio Regulations etc. as these are derived from sources not known to be in the public domain.
Instead, please write your own definitions for these terms in your own words.
