FS-1052: Foreword

FED-STD-1045A, Telecommunications: HF Radio Automatic Link Establishment, October 18, 1993, provides Federal departments and agencies with a comprehensive description of the performance and interoperability criteria for automatic link establishment (ALE) in high frequency (HF) radio. FED-STD-1045A provides the waveform, coding, and protocols to support ALE and is the foundation for the adaptive and automated radio features that are being defined in a family of Federal HF radio telecommunications standards:

• FED-STD-1046, HF Radio Automatic Networking;
• FED-STD-1047, HF Radio Automatic Message Delivery;
• FED-STD-1048, HF Radio Automatic Networking to Multiple-media;
• FED-STD-1049, HF Radio Automatic Operation in Stressed Environments;
• FED-STD-1050, HF Radio Baseline Parameters;
• FED-STD-1051, HF Radio System Controller Interface;
• FED-STD-1052, HF Radio Modems.

FED-STD-1052 contains technical standards and design objectives for minimum interface and performance standards pertinent to modulators-demodulators (modems) which operate in both automatic and manual high frequency radio systems.

This standard shall be used by all Federal departments and agencies in the design and procurement of modems for operation with HF radio equipment.

Neither this nor any other standard in a high technology field such as telecommunications can be considered complete and ageless. Periodic revisions will be made as required. The recommendations of Federal departments and agencies on improving the content or relevance of this document should be forwarded to:
