INTRODUCTION
Commanders and staff require fast communications on a personal level as
often as it is available.
Since everyone will require a telephone or
another means of communications, installing individual lines for each
circuit will require too much time. To eliminate the time factor, cable has
been used with multiplexing equipment to place many, up to 48 or 96
channels, on a single or double pair of wires.
Placing two or more pairs of wire within an insulated jacket or covering
will make up a cable. Then multisystems can be transmitted over the cable.
Cable also makes it more difficult for the enemy to detect your location
because it eliminates radio transmissions. However, cable is not the most
secure means of communicating.
There are different cables used in different locations. You will find one
cable is identified as CX-11230/G and another cable is identified as CX-
11230A/G. The difference is its make up and what it will do for the system
to which it is connected. Another cable used in signal battalion is the 26-
pair cable CX-4566/G. This is a local nodal system that uses short pairs of
wires to complete the circuits. Then there is the new cable. Fiber optic
cable eventually will replace all metallic cable.
We will be discussing
this and the other cables within this subcourse.
In addition, we will be discussing the different methods/practices used in
constructing these cable lines.
You will find they are similar, yet they
appear different.
You, the 31L Wire Systems Installer, must be able to correctly install all
the cables to be discussed within this subcourse.
You must know the
different methods of construction because that will save you precious time
when constructing the cable system.
PART A - 26-PAIR CABLE CX-4566/G
1.
Twenty-six pair cable is a stranded conductor with 26 pairs of wires.
The insulation on the wires is color-coded to ease connecting the end
connectors by repairmen.
The 26-pair cable is known universally as
CX-4566/G.
2.
It provides cable distribution for local telephone lines
and circuits,
and interconnects communication shelters.
It is also used
with a cable
stub, or pig tail, 15 feet long and it is known as CX-4760/U.
The CX-4760/U
wires are also color-coded. The stub is used when there are
no facilities
with a universal connector available.
