MAC Layer Frame Format (LLC)

This toggle field determines the interpretation of the two byte field which follows the source
address in a frame. In an IEEE 802.3 frame, this field is interpreted as the length of the frame.
In an Ethernet Version 2.0 frame, this field is interpreted as the frame type and is followed by
another three byte field of which the first two bytes contain the length and the third byte is
reserved. The LINCS uses a frame type of hex 80D5 for Ethernet Version 2.0 frames. The
gateway and the DSN controllers must be configured to use the same frame format.
