Q

What is meant by the acronym “EOS" in a DSC message?

🔍 Key Concepts

• DSC (Digital Selective Calling) terminology used in GMDSS VHF/MF/HF radios • How messages are started and terminated in digital communications • Standard abbreviations used in distress and safety communications

💭 Think About

• Think about what part of a DSC message this acronym might refer to: the beginning, middle, or end? • Which option sounds most like a standard communications control term, similar to what you might see in teletype or computer protocols? • Ask yourself: in an automated digital radio system, what short phrase would be needed to mark that no more characters or data are coming?

✅ Before You Answer

• Verify which of the options is an actual, recognized term in maritime DSC/GMDSS documentation. • Check whether the word "sequence" or "signals" is more commonly associated with message framing in digital systems. • Eliminate any choice that sounds made up or not used in radio or data communications contexts.
