JAM Output:
Collisions are propagated through the
network using the JAM signal of an
alternating pattern of 1's and 0's in
accordance with 802.3 specifications for a

Fragment Extension: Packet fragments are extended to a
minimum of 96 bits using the JAM [1,0].
Fault Protection:
Each segment will disconnect itself from
the other segments if 31 consecutive
collisions occur, or if the collision detector
of a segment is on for longer than
approximately 110
