FS-1052: Letter of Promulgation

1. SCOPE. The terms and accompanying definitions contained in this standard are drawn from authoritative non-Government sources such as the International Telecommunication Union, the International Organization for Standardization, the Telecommunications Industry Association, and the American National Standards Institute, as well as from numerous authoritative U.S. Government publications. The Federal Telecommunications Standards Committee (FTSC) HF Radio Subcommittee (HFRS) Standards Development Working Group (SDWG) developed a family of High Frequency Automatic Link Establishment (ALE) specifications that defines the necessary technical parameters for automatic link establishment for HF radio connections. Federal Standard 1052 is one of the family of standards to be used in conjunction with the interoperability criteria for HF radio automatic link establishment operation.

1.1 Applicability. All Federal departments and agencies shall use Federal Standard 1052 as the authoritative source for the design and procurement of modulators-demodulators (modems) and of definitions for terms and functions used in the preparation of all telecommunications documentation. The use of this standard by all Federal departments and agencies is mandatory.

1.2 Purpose. The purpose of this standard is to improve the Federal acquisition process by providing Federal departments and agencies with a comprehensive, authoritative source for modems for HF radio.

2. Requirements and Applicable Documents. The HF radio modem terms, definitions, waveforms, and protocols which constitute this standard are to be applied in the design and procurement of HF radio modems. There is a family of Federal Telecommunications Standards and proposed HF radio automatic link establishment standards that may be applicable to implementation of this standard and these are listed in the standard.

3. Use. All Federal departments and agencies shall use this standard in the design and procurement of HF radio modems. Only after determining that a requirement is not included in this document may other sources be used.

4. Effective Date. The use of this approved standard by U.S. Government departments and agencies is mandatory, effective 180 days following the publication date of this standard.

5. Changes. When a Federal department or agency considers that this standard does not provide for its essential needs, a statement citing inadequacies shall be sent in duplicate to the General Services Administration (KMR), Washington, DC 20405, in accordance with the provisions of the Federal Information Resources Management Regulation, Subpart 201-20.3. The General Services Administration will determine the appropriate action to be taken and will notify the agency.

Federal departments and agencies are encouraged to submit updates and corrections to this standard, which will be considered for the next revision of this standard. The General Services Administration has delegated the compilation of suggested changes to the National Communications System whose address is given below:
