Packet Mode Data
A half-duplex bi-directional communication
link in which data is accumulated in
packets of various lengths and sent out in
a burst or bursts so therefore does not
support voice communications. Packet
switching is the process of routing and
transferring data by means of addressed
packets so that a channel is occupied
during the transmission of the packet only.
Upon completion of the data transfer, the
channel is made available for the transfer
of other traffic. Supported by a UniLink
ARINC port configured to provide VHF
