This is 12% of the maximum allowable distance for 100BASE-TX full-duplex twisted-
pair media (100 m) [12/100 x 100% = 12%]. The total of the two percentages (57% +
12%) is 69%, which is allowable.
3.2.2
Segment Distances, Half-duplex
Fast Ethernet shared bandwidth devices operate with multiple nodes in a traffic
domain. When a node attempts to send a packet, it may hit another packet passing by,
i.e., a collision may occur. This is normal and does not cause a problem because the
Ethernet protocol provides for this situation and requires that the sender wait and try
again. When installing the Magnum 15E in a half-duplex segment, it is important to
consider the collision domain of the segment, including the 15E itself, repeaters and hubs
present, and the lengths of both of the attached media types.
