STRUCTURED WIRING
This chapter focuses on standards for structured cabling
network and telecommunications facilities that are thecentral point for wiring and equipment.

STRUCTURED WIRING SYSTEMS
THE NEED FOR STRUCTURED
WIRING SYSTEMS
It is a method for creating an
organized cabling system can be
easily understood by installers,
network administrators and other
technical work with cables.

SUBSYSTEMS
There are five sub-systemsrelated to structured
cabling system.

CABLE HEAD AND
DOCUMENTATION
The labeling is a basic part of astructured cabling
system. There may be
confusion if the cables are
clearly labeled at both ends.

RECORDING PROCESS
represents the use of
cable spool labels for a
time to connect the
cables, do not confuse the
spool from which they
come.

RECORDS
Registration is an importantpart of the structured
cabling system. The
standards require careful
records.

RECORDS OF CABLE AND TEST
DATA
The registration of a cablerequires a cable going from
point A to point B, there is
scope to elaborate on
this. One of these is the type
of copper cable / fiber.

DATA OF THE BOARD OF
TELECOMMUNICATIONS
The data could be recorded
with respect to the type andlocation of the
telecommunications room
(distributors) may also be
registered in the database ofstructured cabling system.

ROUTE DATA FOR
TELECOMMUNICATIONS
The stands and stairs withcable supplying the
telecommunications room
deserve to be documented.

NETWORK EQUIPMENT
RECORDS
The network infrastructure
equipment such as switches androuters, are often the most
expensive part of the network
infrastructure in an
organization. For this reason, it is
important that these devices are
documented.

REMOVAL OF ABANDONED CABLE
Many electrical or fire codesspecify that cable must not be
abandoned. The cable access is
not connected or marked for
future use is considered
abandoned.

APPLICABLE STANDARD WIRING
In general, there are local
standards related to wiring,since it affects the building
codes and fire. national
standards exist for the United
States, Canada, Australia and
New Zealand and the
European Union.

INSTALLATION OF INCOME
Installation of income (EF, Entrance Facility) is the
point at which the cables outside the buildingthrough the wall or go to the basement. In some
cases, the EF is shared with the facilities of income
from other services. In other cases, there is a room
or a panel for the EF.

DEMARCATION POINT
The demarcation point is the
point at which the externalwiring is connected to the
backbone cabling within the
building. Represents the
boundary between the
responsibility of the service
provider and the customer.

INSTALLATION OF INCOME
Installation of income (EF,
Entrance Facility) or thedemarcation point
(DeMarco), provide the point
at which the external wiring is
connected to the backbone
cabling within the building.

ROOMS AND TELECOMMUNICATIONS
EQUIPMENT
A telecommunications room
(TR, TelecommunicationsRoom) is an area within a
building that houses the
computers in the
telecommunications cablingsystem.
8/9/2019 Diapositivas Cap7 ING
20/50
AREAS OF WORK
The area where there is
a single
telecommunications
room is called the
workspace. In most
cases, a work area
occupies a floor or partof one floor of a
building.

WIRING DENSITY
Wiring density is the number
of cables that come in a
telecommunications room
8/9/2019 Diapositivas Cap7 ING

LOCATION OF THE BOARDS OF
TELECOMMUNICATIONS
Telecommunications rooms
should be located away
from sources of
electromagnetic
interference such as
transformers, motors, x-
rays, induction heaterscurrents, radios and radars.

ASSEMBLY EQUIPMENT
The equipment mounting
racks or walls common sensealso requires compliance with
the standards.

LIGHTING
It is important for
telecommunicationsrooms, besides being
safe, also have adequate
lighting.

TEMPERATURE AND HUMIDITY
The telecommunications room must have
adequate heating, ventilation and air
conditioning (HVAC) to maintain room
temperature at approximately 17 C and
21 C (64 F and 75 F) while all
teams LAN are fully operational.

Devices for managing
cables are used to routecables and provide a neat
and orderly path for the
cables.

CROSS CONNECTION CABLES
8/9/2019 Diapositivas Cap7 ING
34/50
There is a clear distinction between connection and
cross connection. The crossover is performed morefrequently in the MC and the IC because these
connections are relatively permanent. The connection is
made when changes in connectivity are often made or
planned in advance

CROSSED WIRES
A crossover cable can be used as
trunking or backbone cable to
connect two or more hubs or
switches to a LAN, or to connect
two remote workstations to
create a LAN Mini.

DIRECT CABLE
A direct connection
cable maps thecable to the same
pins on both ends

CABLE TRANSPUESTRO
The rollover cable is used
as a console cable to
connect a computer to arouter or switch through
the console port.

OPTICAL FIBER BACKBONE
This is because these fibers are impervious to
electrical interference and radio frequencyinterference. In addition, fiber does not carry
currents that might cause loops in the ground

MULTIPLE COPPER CABLE PAIRS
A typical method for moving large numbersof signals, like a backbone, is to use a multi-
pair cable

BACKBONE CABLES PAIR OF FOUR
TIED
When the fiber optic cables or multiple pairsare not an option, tie the four-pair cables for
transport.
