QUESTION ONE
1.1.
The following are principles of structured cabling to setup a professional
computer network
Definition of Structured Network:
Structured cabling is a type of infrastructure that supports the performance of an
organization’s cabling system or network. It is the glue that binds all PCs, phones and
other devices used within the business together – providing a reliable and versatile
solution to a wide range of communication requirements.

Below are the Importance of Network Structure and its overview:
Businesses depend on a network infrastructure for all aspects of daily operations.
Reliable customer contact ensures gaining new clients and retaining current ones. ...
Communication between business and client is one of the most important aspects of
retaining happy customers, whether it is by phone or email.
OVERVIEW SOLUTION BASED ON 1.1
Essentials of Networking: Structured Cable Network Components for to network all
three floors of the main office
Successful implementation of a basic structured cabling network requires three
essential ingredients: a telecommunications room, horizontal cabling, and a work area.
Essential ingredients to be used to network all three floors
Horizontal Cabling A horizontal cabling run is the cabling that goes more or less
horizontally from a work area to the telecommunications room. In most networks, this
cable is a CAT 5e or better UTP, but when you move into structured cabling, the TIA/

EIA standards define a number of other aspects of the cable, such as the type of wires,
number of pairs of wires, and fire ratings.
EXAM TIP A single piece of cable that runs from a work area to a telecommunications
room is called a run. In most networks, this cable is CAT 5e or better UTP.
Solid Core Versus Stranded Core All UTP cables come in one of two types: solid core
or stranded core. Each wire in solid core UTP uses a single solid wire. With stranded
core, each wire is actually a bundle of tiny wire strands. Each of these cable types has
its benefits and downsides. Solid core is a better conductor, but it is stiff and will break if
handled too often or too roughly.
Stranded core is not quite as good a conduc- tor, but it will stand up to substantial
handling without breaking. Figure 20-22 shows a close-up of solid and stranded core
UTP.
Ceiling Installations
TIA/EIA specifies that horizontal cabling should always be solid core. Remember, this
cabling is going into your walls and ceilings, safe from the harmful effects of shoes and
vacuum cleaners. The ceilings and walls enable you to take advantage of the better
conductivity of solid core without the risk of cable damage. Stranded cable also has an
important function in a structured cabling network, but I need to discuss a few more
parts of the network before I talk about where to use stranded UTP cable.
Solution based on using structured cabling for the three floors:
Structured cabling for all three floors of the main office...
Structured cabling is the design and installation of a cabling system that will support
multiple hardware uses and be suitable for today's needs and those of the future. With a
correctly installed system, current and future requirements can be met, and hardware
that is added in the future will be supported .
Structured cabling design and installation is governed by a set of standards that specify
wiring data centers, offices, and apartment buildings for data or voice communications
using various kinds of cable, most commonly category 5e (Cat 5e), category 6 (Cat 6),
and fiber optic cabling and modular connectors.

These standards define how to lay the cabling in various topologies in order to meet the
needs of the customer, typically using a central patch panel (which is normally 19inch rack-mounted), from where each modular connection can be used as needed.
Each outlet is then patched into a network switch (normally also rack-mounted) for
network use or into an IP or PBX (private branch exchange) telephone system patch
panel.
Lines patched as data ports into a network switch require simple straight-through patch
cables at each end to connect a computer.
Voice patches to PBXs in most countries require an adapter at the remote end to
translate the configuration on 8P8C modular connectors into the local
standard telephone wall socket.
No adapter is needed in North America as the 6P2C and 6P4C plugs most commonly
used with RJ11 and RJ14 telephone connections are physically and electrically
compatible with the larger 8P8C socket.
RJ25 and RJ61 connections are physically but not electrically compatible, and cannot
be used. In SA, an adapter must be present at the remote end as the 6-pin BT socket is
physically incompatible with 8P8C.
It is common to color-code patch panel cables to identify the type of connection, though
structured cabling standards do not require it except in the demarcation wall field.
Regardless of copper cable type (Cat 5e/6/6A), the maximum distance is 90 m for the
permanent link installation, plus an allowance for a combined 10 m of patch cords at the
ends.
Cat 5e and Cat 6 can both effectively run power over Ethernet (PoE) applications up
to 90 m. However, due to greater power dissipation in Cat 5e cable, performance and
power efficiency are higher when Cat 6A cabling is used to power and connect to PoE
devices.

NB: Structured cabling consists of six subsystems:
Therefore the below subsystem will be considered and used in the installations of the
structured network for all the three floors to the main office.

Entrance facilities is the point where the telephone company network ends and
connects with the on-premises wiring belonging to the customer.

Equipment rooms house equipment and wiring consolidation points that serve the users
inside the building or campus

Backbone cabling is the inter-building and intra-building cable connections in structured
cabling between entrance facilities, equipment rooms and telecommunications closets.
Backbone cabling consists of the transmission media, main and intermediate crossconnects and terminations at these locations. This system is mostly used in data
centers.

Horizontal cabling wiring can be standard inside wiring (IW) or plenum cabling and
connects telecommunications rooms to individual outlets or work areas on the floor,
usually through the wireways, conduits or ceiling spaces of each floor. A horizontal
cross-connect is where the horizontal cabling connects to a patch panel or punch up
block, which is connected by backbone cabling to the main distribution facility.

Telecommunications rooms or telecommunications enclosure connects between the
backbone cabling and horizontal cabling.

Work-area components connect end-user equipment to outlets of the horizontal cabling
system.
Cloud backup for all three floors:
Drop-Box will be used as a cloud backup service that saves their computer data to an
offsite location so it isn't only on the hard drive.

Conclusion
From Fortune 500 to small startups, all companies need a good communication system
to support services such as WLAN, LAN, ISDN and ASDL. A company should have
cabling infrastructure that can provide flexibility and predictable performance so that
they can easily add, move and alter devices to maximize system availability.
Structured cabling forms the basis of the telecommunication system of modern
business. It offers a general environment for data transmission by integrating telephone
networks, video surveillance, security, local computer and other systems together. A
structural cabling system supports multiple voices, data and multimedia systems. It
basically means crafting a cabling infrastructure that comprises of sockets, cables and
cable distributors.
