3. Picket

Link 11

In____ mode, units can only receive data. They are not able to poll other units or respond to polling.

Link 11

_____ enables the NCS to transmit a continuous preamble which each picket receives and uses to synchronize their internal time bases

Link 11

____ enables the NCS to transmit a test pattern, which receiving units use for a comparison to check the system connectivity.

Link 11

____ happens when a unit seizes control of the net and continually transmit messages until it has nothing more to transmit or until the net returns to roll call mode. Every other unit can only "listen"
