What mode must the MIDS terminal be in to transmit messages on the network?

• A. Coarse Sync
• B. Standby
• C. Fine Sync
• D. Normal Sync

Answer: (C)

Link 16 networks run on a TDMA timing schedule, so a terminal must be tightly synchronized to the network time to send in the correct slot. Coarse synchronization only aligns to the frame roughly and isn’t precise enough to guarantee a safe, collision-free transmission. Standby keeps the terminal out of the network, so it can’t transmit. Normal synchronization allows participation at a basic level, but the precise timing needed to place a message into the proper TDMA window comes with Fine Sync. Since that high-precision timing is required to transmit on the network, the terminal must be in Fine Sync.
