Which entity provides time synchronization to a unit joining a Link 16 network?

• A. Data Terminal Equipment
• B. Network Time Reference (NTR)
• C. Crypto device
• D. Network Control Station (NCS)

Answer: (D)

Time synchronization in a Link 16 network is driven by a central master clock that coordinates when every unit transmits. The Network Control Station serves as that master clock and distributes the Network Time Reference to devices that join the network. When a unit joins, it uses this reference to align its internal timing with the network, ensuring its TDMA transmissions occur in the correct slots and without collisions. The Network Time Reference is the timing signal itself, but the entity that provides and distributes that timing to new entrants is the Network Control Station. Data terminal equipment is just the user’s interface, a crypto device handles encryption keys rather than timing, and the timing signal would not be provided by the NTR alone without the NCS coordinating its delivery.
