This database is a comprehensive selection of computer-generated audio modem tones for testing the interoperability of Automatic Link Establishment (ALE) High Frequency (HF) radios that have been built to the specifications of Federal Standards (FED-STD)-1045A and 1046/1.

The database has been recorded on a single 47 minute audio compact disc (CD) in 62 tracks. The CD also contains a narrative on the purpose and use of the data, and a set of calibration tones for aligning the system under test.

The database tones on the CD are perfect representations of the calls required by the referenced Federal Standards, because the tones were generated in a computer package. It contains instructions and documentation for each of the test tracks and information on how to perform the tests.

The ALE Clean Tone Audio CD has the following features:

• introductory and calibration tracks
• nine tracks of SOUNDS with and without noise
• one hundred quick SOUNDS with a variety of addresses
• ALL CALLS, and selective ALLCALLS
• INDIVIDUAL calls
• star NET and GROUP calls
• ANYCALLS and WILDCARD calls
• special purpose calls.

The 3.5" floppy contains:

• all the protocol files used to generate the ALE audio modem tones
• the test plan to conduct the interoperability tests
• data log sheets keyed to each track on the CD, to record the test data
• software to generate ALE audio sound files from the protocol files
• documentation of the entire package and how to use it.

The audio CD should be played on a consumer-quality audio player; the 3.5" high density floppy disk is intended for use with PCs.
