STRUCTURED WIRINGCHAPTER 7


2/50

STRUCTURED WIRING

This chapter focuses on standards for structured cabling

network and telecommunications facilities that are thecentral point for wiring and equipment.


3/50

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.


4/50

STRUCTURED WIRING RULES


5/50

STRUCTURED WIRING

SUBSYSTEMS

There are five sub-systemsrelated to structured

cabling system.


6/50

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.


7/50

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.


8/50

RECORDS

Registration is an importantpart of the structured

cabling system. The

standards require careful

records.


9/50

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.


12/50

ROUTE DATA FOR

TELECOMMUNICATIONS

The stands and stairs withcable supplying the


deserve to be documented.


13/50

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.


14/50

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.


15/50

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.


16/50

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.


17/50

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.


18/50

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.


19/50

ROOMS AND TELECOMMUNICATIONS

EQUIPMENT

A telecommunications room

(TR, TelecommunicationsRoom) is an area within a

building that houses the

computers in the

telecommunications cablingsystem.


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.


21/50

WIRING DENSITY

Wiring density is the number

of cables that come in a



22/50

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.


23/50

ASSEMBLY EQUIPMENT

The equipment mounting

racks or walls common sensealso requires compliance with

the standards.


24/50

GROUNDING BARS FOR

TELECOMMUNICATIONS


25/50

DOORS AND LOCKS

great importance for network equipment

that is in the telecommunications room

dictate the steps to be followed to ensure

good physical security.


26/50

SPECIFICATIONS FOR WALLS,

FLOORS AND ROOFS


27/50

LIGHTING

It is important for

telecommunicationsrooms, besides being

safe, also have adequate

lighting.


28/50

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.

CABLE MANAGEMENT

Devices for managing

cables are used to routecables and provide a neat

and orderly path for the

cables.


31/50

OTHER OPTIONS OF FLOOR AND

CEILING

The raised floors and false

ceilings can also support

patch panels.


32/50


33/50

CROSS CONNECTION CABLES


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

CONNECTION CABLES


35/50

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.


36/50

DIRECT CABLE

A direct connection

cable maps thecable to the same

pins on both ends


37/50

CABLE TRANSPUESTRO

The rollover cable is used

as a console cable to

connect a computer to arouter or switch through

the console port.

DISTRIBUTOR OF FLOOR

(HORIZONTAL CROSS CONNECT (HC)

Floor Distributor (FD) orhorizontal cross-connect

(HC) is the

telecommunications

room (TR) is closest to

the workstations

HORIZONTAL AND VERTICAL

DISTRIBUTION (BACKBONE WIRING)


43/50


44/50

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


45/50

MULTIPLE COPPER CABLE PAIRS

A typical method for moving large numbersof signals, like a backbone, is to use a multi-

pair cable


46/50

BACKBONE CABLES PAIR OF FOUR

TIED

When the fiber optic cables or multiple pairsare not an option, tie the four-pair cables for

transport.


47/50

WIRING IN THE AREA OF WORK

Workspaces

The wiring in the work area

extends from the

telecommunications outlet to

the computer workstation
