What does DSC Stand for?

• A. Digital selective calling
• B. Digital system control
• C. Data sequential communication
• D. Direct satellite communications

Answer: (A)

Digital Selective Calling is a digital signaling method used in maritime radio that lets you call a specific vessel or shore station and send distress, safety, or routine messages without speaking. Each vessel has an MMSI that identifies the intended recipient, so the call is directed rather than broadcast to everyone. This selective addressing improves reliability and speeds up response, especially in emergencies, because the distress alert or call is automatically routed to the right stations and can be logged/acknowledged through the DSC system. The other options don’t capture this combination of digital addressing and selective calling capability, which is why Digital Selective Calling is the correct term.
