Straight-Through Wiring for the 3H02-04
If the twisted-pair link segment is to join two ports and only one of the
ports has an internal crossover, the two pairs of wires must be
straight-through, as shown below.

Limitations & Restrictions
Between any two nodes (such as PCs or other stations) on the network,
there may be limitations or restrictions that you should be aware of. For
more information on any limitations or restrictions, see the IEEE 802.3
specification.

Backbone
A coax segment with hubs, possibly file servers.
Cascade
A method of interconnecting hubs using their ports rather than their
stacking connectors.

Link Segment
A length of twisted-pair or fiber cable joining a pair of devices in a star
topology (e.g., two hubs or a hub and a station).
