The fictitious company chosen will be a small organization that
specializes in merchant services. The fictitious company will
deal with check verification, online payments, debit cards, and
credit cards. In order for this fictitious company to accomplish
these services, the company has established partnerships with
major banks and financial institutions, The gained partnerships
with the major banks and financial institutions allows access to
the partner’s databases. The databases contain listings of
people who are known to write bad checks and have abused the
banks and other financial institutions online payment services.
The company’s ability to access its partner’s databases is
imperative to its success; ability in assisting merchants with
payment processing at the point of sales. The specialized check
verification process will prevent anywhere from 50 to 75% of
returned checks, thus reducing fraud and returned checks before
they happen. In addition to their check verification services, its
online verification software has refined controls to inhibit
people from stealing other client’s identities.
The small organization (company) is comprised of four separate

departments, these four departments are essential in running an
efficient, reliable, and secure network system These
departments will be able to communicate with each other
efficiently and keep the daily operations running successfully
and accurate. The company will need to keep in mind the
prevention of fraud, which is why the company designs a strong
and reliable network security program. In case of program
failure the networking program must provide network access to
the majority of its employees through segment and sufficient
cabling, thus eliminating the possibility of a decrease of
productivity. With all this said the company’s network will
provide the ability to share central devices such as scanners,
copiers, printers, thus providing external and internal data for
traveling salespeople to access. Finally, the network will have a
central storage unit for file sharing, which will be used amongst
the four departments, and the system capabilities will include an
internal authentication, verification process for all authorized
employees and expansion capabilities for additional devices
when the need arises.
The best choice overall would be to implement a star topology
network in each department’s office. This type of network
allows for manageability and ease, the network uses a hub as a
central point of link for the computers and other devices on the
Local Area Network (LAN). These devices are connected to the
network by connecting the device to the hub by its own separate
cable. The star topology network also allows for expandability
without difficulty, this also depends on how many ports are on
the hub that are being used. According to Hallberg (2005) each
hub usually hosts about 24 nodes, but hubs that do, can exist in
range from two nodes up to 96 nodes. Keeping in mind if the
hub only allows access for 10 continuous than only 10 devices
can be added, but if more ports are needed on the hub, two hubs
can linked together to provide more connectivity. When the
company needs to add more computers, this can be
accomplished by easily connecting the computers to the port on

the hub, providing that space is available for this type of
expansion. The advantage of a star topology; not having to shut
down network and interfering with other devices while the
network is up and running.
The disadvantage of such a network is that a great deal of
cabling is required that can sometimes result in high overhead
costs; much more actual wire is required, the labor to install
wiring, and the additional cost for added hubs. (Hallberg) 2005.
When considering costs, another way to go is connecting via
wireless, but this should be kept to a minimal, due to
connections are sometimes blocked by outside variables. So
one must keep in mind strategic planning and if done correctly a
reasonable budget is possible. Another disadvantage is the
weakest point of the network topology; the central hub, the
malfunction of the central hub affects the entire network.
Designing the network in a simple manner will allow the
company too easily to maintain the system. Connecting each
department within the organization using the star topology, the
connection will terminate to separate network devices located in
Intermediate Distribution Frame (IDF) or intermediate
distribution frame closet. The closet will hold the switch that
connects to the network’s router. Since the departments are
located within close proximately of each other, this is the best
layout and permits the system to be expandable and accessed
with ease.
The star topology offers a wide variety and different types of
cabling options. Some of the various cables that can be used by
a star topology network are; coaxial cable, fiber optic cable and
twisted pair cable. According to Hallberg (2005) networks with
lower requirements one can use higher-rated cabling systems.
The twisted pair cables are available in several categories that
are ranged by their performance. The most commonly used to

connect to personal network computers is the Category 5 (Cat-
5). The company’s network design will use twisted pair cables
to connect to the hubs to the MDF will be 10base-T (10 Mbps,
twisted-pair (two pairs, Cat-3 or higher) cable. The decision to
use 10base-T cable is because of its maximum length: 100
meters. Another possible choice that is used, but not as
commonly in LAN networks: coaxial cable.
Coaxial cable are found more in older networks (those built
prior to circa 1992) and the coaxial cable is of the thin variety
(RG-58), Fiber optic cable is a faster option, come in a variety
of types ranging in speed and length and capable of transmitting
data at unbelievable speeds. (Hallberg, 2005) Also according
to Kozel, Art and Armas, Ruben, (2005) “Fiber cabling is used
to enhance performance over short distances as well.” Due to
our company’s size, we went with cost, Cat-5 and 10base-5
cables are far much cheaper and supply the necessary support
needed for our company’s network design.
When installing network cabling our company is using a
‘Network Cabling Specification Checklist. The network cabling
specification checklist provides the requirements for installation
of cabling for the network. Using the checklist will provide
proper cable and connectors to be installed. Labeling said
cables and connectors will save time and money in the long run.
Documentation is highly important; the document should entail
certification reports that show all the installed cables operate
properly and that a special network test device was used.
Network Cabling Specification Checklist
· Category 5E Cable
· Category 5E patch cable
· RJ45 connector
· Category 5E cable should expand 100 meters in length

· 10Base-T cable
Choosing this type of topology will provide outstanding
opportunities for expansion and management as well as help
support the company’s network goals.

Network Design Final Project Overview and Timeline
Final Project Overview
Your task is to draft a top-level design of an enterprise-wide
telecommunications network for a fictitious company, including
requirements, LAN topology, and WAN infrastructure that will
handle a constant stream of traffic between offices.
Objective
Define the network topology in each office LAN, and define and
describe the structure of the WAN to interconnect the offices.
Describe the types of equipment you will need, and explain how
you will meet the performance reliability requirements. Discuss
the relevant protocol choices for both the LANs and the WAN.

This is to be a top-level design, and students are not expected to
identify brand names, model numbers, or pricing of any items in
this network design.

Final Project Overview and Timeline
Final Project Overview
The final project consists of a currency conversion application.
This application—similar to simple, practical programs on many
travel or financial Web sites—includes the following elements:
· Complete requirements analysis
· Design
· Verification
· Validation and test documentation
The Currency Conversion application is a menu-driven program
that allows users to select one of five international currency
types, input the amount of a foreign currency, and then convert
the foreign currency to dollars. The program displays the
equivalent dollar amount and returns the user to the menu until
he or she enters another conversion or quits the program.

International currency type (menu selection)
· Canadian dollars
(rate: 1 U.S. dollar = 1.4680 Canadian dollars)
· Mexican pesos
(rate: 1 U.S. dollar = 9.5085 pesos)
· English pounds
(rate: 1.6433 U.S. dollars = 1 pound)
· Japanese yen
(rate: 1 U.S. dollar = 104.9200 yen)
· French francs
(rate: 1 U.S. dollar = 6.2561 francs)
