To ensure that design wiring projects structured are effective and efficient, raised thefollowing rules:

Find a complete solution for

connectivity: To achieve networkconnectivity solution covers all systems

that are designed to connect, build,

manage and identify structured cabling

systems.


5/74

Plan for future growth: It is

essential that any new installation

complies with the standards to

ensure that the infrastructure is in

place.

Note the total cost of ownership:

Great part of the installation and

long-term costs associated with

modern network systems aredirectly related to reliability and

network connectivity .


6/74

Keep the freedom to choose

providers: A system with a single

vendor, and that does not comply with

the standards, will make it harder tobe able to change the addresses

below, although there are short term

assurance and certification benefits.

There are five subsystems system wiring-related structured:

Point of demarcation (demarc).

Chamber Telecom (TR).

Cabling backbone (cabling vertical).

Cabling distribution (wiring horizontal).

Workspace.


9/74

The point of demarcation (demarc) is located where external

cables from the provider service work together with the local

system. Backbone cabling is the "main line" of the system.

Horizontal cabling distribution services in the areas of work.

11/74

All major standards specify thateach hardware connection drive

must have a unique identification.

This identifier must be marked on each unit of

the hardware or its label; connections forworkstations must have a label on board, rack

or connector.


12/74

Cables are labelled once they

are cut from the reel, each

connection cable also mustlabel in the panel room

telecommunications connection

this facilitates localization and

the diagnosis of problems.


13/74

Make sure the cord to the laying ofcables be loose, tying some knots

around cables, by placing the tape at the

ends.

It is also good practice the registering of

beginning and end of a cable distances

using distance indicators marked in the

lining of the cable.


14/74

IEC suggests the following to register:

Cables: Type and number of cables and pairs, location of

the endpoint.

Shots of the workspace: Type, label, informationlocation.

Boards of telecommunications (distributors): Number

of room, type, description, connections, location.

Floor plans: Shots, telecommunications rooms and

routes cabling locations.


15/74

IEC recommends that system wiring information is maintained in a database with five

fields:

Field 3: Component identifier

Field 1: Specific location Field 2: Overall location

Field 4: Port number

Field 5: Physical data


16/74

Organized cables installation notes can include:

Type of cable (fiber or copper) . Manufacturer, cladding and marking of the kernel.


17/74

Number of conductors and available pairs.

Notes and locations of joints and cross-

connections.

Notes on connections and sunsets to land.


18/74

Inside of the data to store you can include the following:

Type, used and available .

Characteristics of the cable

(if it is protected or not).

Available pairs of wires (telephony).


19/74

If the cable is connected or not.

Notes on the journey that makes

the cable back to the room of

telecommunications.

Notes on joints and connections to land.


20/74

To store data can include the following:

Information on routes that feed the

telecommunications room.

Number and type of wires, cables in use as

available.


21/74

Diagrams of scenes, including location and

frontal views showing space for more

computers that will be added over time.

Notes on the power, backup power and

environmental controls.


22/74

The tiers and stairways wiring that feed the telecommunications room might includethe following:

The nature of the path. Path attributes


23/74

Details about the materials required or

used to stop the fire.

Records of cables installed in the path .

Information regarding ground, earthing and

Union to land.


24/74

Switches and routers, are often the most costly part of networkinfrastructure in an organization.


25/74

Cable access is not

connected or marked for

future use is considered to

be abandoned. Abandonedcable is a source of fuel for

fires. Abandoned cables

can also form a track

voltage, as well as be the

source or driver EMI and

RFI.


26/74

A building, security, sensor

firefighting and surveillance,

temperature control standards are

becoming increasingly criticalbecause the designers of these

industries have a fixed idea on

how to make your computer work

in common network.


27/74

TIA/EIA-568-B: Specifies the transmission and components for media requirements.

TIA/EIA-569-A: Routes and spaces of cables.

TIA/EIA-570-A: Wiring residential and commercial child.

TIA/EIA-606: That includes labeling cables in plant management standard.

TIA/EIA-607: Grounding and connection requirements.

Requirements of routes and spaces of the

construction, management and electricity:


28/74


29/74

Installation of income (EF), isthe point where cables from

the exterior of the building

facing wall or go to the

basement.


30/74

The demarcation point is the point atwhich the external cabling connects

to backbone cabling within the

building. Represents the boundary

between the responsibility of the

service provider and the customer.

Everything that happens from thepoint of demarcation in the building

is the responsibility of the customer.

The service provider is responsible

for everything that occurs from the

demarcation point to the installationof the service provider.


31/74


32/74

Once the cable enters the building throughthe demarc, arrives at the campus reseller

or the distributor of building, known also as

connection crusade lead. This is the center

of the voice and data network.


33/74

Telecommunications (TR) room is an area within a building that hosts system wiring of

telecommunications equipment. This includes mechanical connections and/or cross-

system wiring backbone connections and horizontal.


34/74

Factors to consider when planning a network:

Where to locate the room telecommunications (TR).

The proximity to the backbone cabling.

A TR should have easy access.

Accessibility and security.


35/74

Where works individually telecommunications room workspace is called.


36/74

Devices for administration of the wiring can be costly, and location of heating, ventilation

and air conditioning equipment, transformer and equipment lighting can determine more

extensive routes.


37/74


38/74

The wiring density refers to the number of cables that come into a room of

telecommunications.


39/74

These should be located away from sources of electromagnetic interference such as

transformers, motors, etc., must be located so that it is possible to accesstelecommunications network connectivity when you make changes to the structure of

the building.


40/74

ISO/IEC TR 14763-2 and EN 50174-1 provides general

recommendations on the location of computers, but the ANSI/TIA/EIA

569-A standard makes it more in detail.


41/74

Connecting and binding to land must be

performed according to standard IEC 60364

applicable national codes.

The TMGB connects to other

grounding bars called

telecommunications earthing

bars.


42/74

Telecommunications earthing bars (TGB)

Telecommunications earthing bars must be made of copper and connecting cables

of Union land length.


43/74


44/74


45/74

To build the communications room, complying with all applicablecodes fire prevention materials should be used.


46/74


47/74


48/74

It is important that telecommunications rooms also have adequate lighting.


49/74

Telecommunications room shall be sufficient

heating, ventilation and air conditioning

(HVAC) to maintain a temperature.

Failure to comply with thesespecifications could cause severe

corrosion of copper wires that are within

the cables.


50/74

The racks are mounted on the floor metal frameworks that support installation of panels

of connection and active equipment such as switches, routers, or firewalls.


51/74

The baskets wire used when you require easy and light facilities;

administration of special cables called internal duct systems are

used for fibre optic cables.


52/74


53/74


54/74


55/74

Cross connection occurs most frequently in the MC and the IC. Theconnection is made when connectivity changes are made frequently, or are

planned in advance.

There is a wide variety of connection cables for different purposes.


56/74

A crossover cable can be used as a junction circuit or backbone, cable connects two

workstations. A cross connect four pairs cable reverses the second and the third pair atone end of the cable.


57/74

Connection cables

are also used to

connect the taking

of the work area to

the workstation.


58/74

The rollover cable is

used as console

cable to connect a

computer to a router

or a switches via the

console port.


59/74


60/74

Campus distributor (CD), is the main point of a campus or

entire building.

A building houses the MC andeach individual building has its

own concentration (IC) that

connects all HC containing.


61/74


62/74


63/74

The HC is a panel connection or a block of puncture and possibly a network

device as a relay, hub or a switches.


64/74

The MC, IC and HC are hierarchical .


65/74


66/74


67/74

Backbone cabling, consists of main and intermediate cross-connections.


68/74


69/74

Fiber optic systems have a high bandwidthand can operate at high speeds.

Multiple pairs cable is used to transmit

large amounts of signals .


70/74

Wiring in the work area

extends from Telecom

decision until the

computer work station.


71/74

MUTO offers greater flexibility and economy for installations with open Office workspacesthat require frequent reconfiguration.


72/74

Points of consolidation

(CP) provide a similar

function to the MUTO,

but access to the point

of consolidation is

limited.
