Within how many minutes should a DSC acknowledgement be completed?

• A. 1 minute
• B. 2.75 minutes
• C. 5 minutes
• D. 10 minutes

Answer: (B)

The key idea here is how quickly a DSC acknowledgement should be sent to confirm reception of a DSC message, which is crucial for timely coordination in safety communications. Acknowledging within a short, defined window keeps the originator informed fast, supports rapid decision-making, and helps prevent delays in responding to the incident.

The 2.75-minute window matches the standard typically used in training and practice exams because it provides a realistic balance: it accounts for normal processing and transmission delays without letting too much time pass, which could slow rescue or response actions. A 1-minute acknowledgement is often impractical given hardware and network delays, while 5 or 10 minutes would be too slow for safety-critical communications and could hinder timely coordination. Therefore, 2.75 minutes is the best fit for this requirement.
