Appendix D: Twisted-Pair Cabling

There are different grades, or categories, of twisted-pair cabling. Category 5 is
the most reliable and is highly recommended. Category 3 is a good second
choice. Straight-through cables are used for connecting computers to a hub.
Crossover cables are used for connecting a hub to another hub (there is an
exception: some hubs have a built-in uplink port that is crossed internally; this
allows you to link or connect hubs together with a straight-through cable
Figure D-1
To determine which wire is wire number 1, hold the cable so
that the end of the plastic RJ-45 tip (the part that goes into a
wall jack first) is facing away from you. Face the clip down
so that the copper side faces up (the springy clip will now be
parallel to the floor).When looking down on the copper side,
wire 1 will be on the far left.

instead).
You can buy pre-made Category 5
cabling, or cut and crimp your own.
Category 5 cables can be purchased or
crimped as either straight-through or
crossover. Inside a Category 5 cable
are eight thin, color-coded wires that
run from one end of the cable to the
other. All eight wires are used. In a
straight-through cable, wires 1, 2, 3,
and 6 at one end of the cable are also
wires 1, 2, 3, and 6 at the other end. In
a crossover cable, the order of the
wires change from one end to the
other: wire 1 becomes 3, and 2
becomes 6. See the dia-
grams on the next page
for more detailed infor-
mation on straight-
through and crossover
cabling.
