How are slot allocations communicated to participating units?

• A. Via periodic operator prompts.
• B. Via network management messages from the NCS that assign non-overlapping time slots.
• C. Through broadcast weather data.
• D. By the unit's own internal clock.

Answer: (B)

Slot allocations in this system are determined by a central scheduler and then distributed to all participants. The Network Control Station acts as the scheduler, creating a TDMA timetable that assigns non-overlapping time slots to each unit. It communicates these assignments to every participating unit through network management messages, so each unit knows exactly when it may transmit and when to listen. This centralized approach prevents collisions and keeps the network organized. Other options don’t fit because periodic prompts aren’t used to assign time slots, weather data isn’t related to slot scheduling, and relying on a unit’s own internal clock would lead to timing drift and potential collisions since slots must be coordinated by the central network timing.
