pairs required for network signals
must be wired to the wall jack in the
following arrangement:
Pair 1 - attach to pins 1 and 2,
Pair 2 - attach to pins 3 and 6,
The twisted-wire pairs for telephone
signals (if used) are attached to the
remaining pins,
Detemnine which conductors are
twisted together, record the wire
colors for each pair and note the pin
to which each wire is attached. For
example, an eight-condijctor cable
may have the color and wire-pair
configuration shown in Table-10.
Networic interconnections are usually
made in a wiring closet.
You must be able to identify and
separate the conductors which are
canning networic signals from the con-
ductors that are used for telephone
operation, Ihe color code and wire-
pair arrangement of telephone cable
will vary from one manufacturer to
another
Interface Cable Wiring
The twisted-pair interface cable
provided has an eight-pin modular
plug at each end that mates with the
twisted-pair network port on the LAN
adapter boardand with an RJ-45
modular wall jack. If you are making
your own interface cables to.use as
dedicated networi< wiring, or as exten-
sion cables, refer to Figure 18 for
wiring infonnation.

Wiring Closet Termination
If you are using the existing wiring in
the building, concentrators are typical-
ly mounted inside the wiring closet,
where the telephone conductors are
terminated at a wiring panel. A seg-
ment of twisted-pair wire is attached .
to the conductors from each network
