How does a unit join a Link 16 network and begin transmitting?

• A. It is pre-loaded with a complete schedule and transmits immediately.
• B. It obtains time synchronization from the NCS and is assigned slots via network management messages.
• C. It negotiates frequency with a central hub.
• D. It uses manual operator input to start.

Answer: (B)

In Link 16, access to the network is time-slotted and centrally managed. A unit must first lock its clock to the network time provided by the Network Control Station, ensuring everyone’s timing is synchronized. Once synchronized, the unit is assigned its specific TDMA slots through network management messages. Only in those assigned windows can it transmit, and the schedule can be updated by the NCS as the network needs. This is why simply having a pre-loaded schedule or manually starting isn’t enough—the network controls timing and slot allocation to maintain orderly, collision-free communication.
