ACTUAL WORK/TRAINING DONE
In my case I was assigned to deal with networking issues and
administering the TANZANIA TELECOMMUNICATION COMPANY LIMITED (TTCL),
Accompanied with other related IT issues these include,
Network troubleshooting
When troubleshooting the network to check if computers are in a
network and all receives internet, ping command was used on the command line
Interface of any of the computer in a network. Ping then IP address of any
available computer on the network was used to check if one computer can
communicate with other computer.
Also to see if a computer connects to the internet Ping gateway
command was used. If there is no any
problem on the network the words reply
from then IP address of the pinged appears.
Patching of Network cables to Jack ports
This is a process of creating a port ready for client computers to
connect to the switch. In this process I had to prepare Twisted Pair cable,
jack port, patching tool. The Twisted Pair cable contains eight different
cables each with a specific color. The jack port contain spaces for inserting
the eight cables, each space is labeled with a specific color of both
connection A and B respectively. Connections A and B are explained in the
Cabling process below. Each cable was punched to its respective place using the
patching tool to connect the cable to the jack port and the other termination
to the punch panel.

Cabling of Twisted Pair
Cable is
the medium through which information usually moves from one network device to
another. There are several types of cables which are commonly used with LANs.
Types of cables used in networks include UTP (Unshielded Twisted Pair) cable,
STP (Shielded Twisted Pair), Coaxial cable and Fiber Optic cable. In this case
I was dealing with twisted pair cabling. Twisted Pair cabling comes in two
varieties: shielded and unshielded. Unshielded twisted pair (UTP) is the most
popular and is generally the best option for school networks. Each pair is
twisted with a different number of twists per inch to help eliminate
interference from adjacent pairs and other electrical devices. The tighter the
twisting, the higher the supported transmission rate and the greater the cost
per foot. UTP comes with categories established by the ETA (Electronic Industry
Association).
These
are 1Mbps voice only (telephone wire), 4Mbps localTalk & Telephone, 16Mbps
10BaseT Ethernet, 20Mbps Token Ring, 100Mbps (2 pair) 100BaseT Ethernet and
1000Mbps (4 pair) Gigabit Ethernet, 5e 1000Mbps Gigabit Ethernet, 6 10000Mbps
Gigabit Ethernet.
The
standard connector for Unshielded Twisted Pair Cabling is an RJ-45 connector.
This is a plastic connector that looks like a large telephone-style connector.
A slot allows the RJ-45 to be inserted only one way. RJ stands for Registered
Jack, implying that the connector follows a standard borrowed from the
telephone industry. This standard designates which wire goes with each pin
inside the connector.
There
are about two connections of the cable wires to the RJ-45 namely connection A
and connection B. These connections differ due to the arrangement of wires
using colors. Both connection A and B were done.
Arrangement
of wires with respect to their colors in connection A starts with
white-green, green, white-orange , blue,
white-blue, orange, white-brown, brown. Connection B arrangement is
white-orange, orange, white-green, blue, white-blue, green, white-brown, brown.
Shielded
Twisted Pair (STP) cable is mostly used in Tanzania Telecommunication Company
limited due to its ability to prevent electromagnetic interference. Each pair
of wires is individually shielded with foil.
Straight and Crossover cable
were designed; the crossover cable was used to connect similar devices/nodes
for example switch to switch, computer to computer. Straight cable was used to
connect switch to computer or switch to the Router.
Router Configuration with DHCP using the packet tracer
DHCP
(Dynamic Hosting Configuration Protocol) is a network protocol that is used to
configure network devices so that they can communicate on an IP network. DHCP
is a network protocol that is used to assign network parameters such as IP
addresses, default gateway, subnet mask, DNS (Domain Name Server) and other
network parameters.
If you want to configure Dynamic Host
Configuration Protocol (DHCP) on PC clients, you currently have multiple
options to choose for your DHCP server. One of the more common ways to
accomplish this is by using a Windows or Linux server. However, most home
networks get DHCP from their DSL or cable router.
Using a router as a DHCP server
has its pros and cons. For example, let's say you have a multisite network, and you've decided to
use your routers as DHCP servers for each network. One benefit of running DHCP
on routers is that it doesn't require any extra hardware (like a Windows server
does). In addition, running DHCP on a router can save your organization the
cost of a dedicated DHCP server. It also provides DHCP locally at each site regardless
of whether the WAN is operational.
But there are some drawbacks. For example, some
administrators might not be too comfortable monitoring and troubleshooting DHCP
from a router; they may prefer to use Windows DHCP Manager rather than Cisco
IOS commands to check the status of client leases, manually terminate a DHCP
lease, or assign a static reservation. In addition, some administrators might
prefer implementing a centralized DHCP server in order to have one place to
monitor and troubleshoot DHCP.
Software Installation
Installation
of different software with best procedures were done, mostly useful software at
Tanzania Telecommunication Company limited are Operating system (7, xp, vista,
Ubuntu, Rubuntu.), Linux mint, Disk bootable image with XP royal 7, and many
other software used by students in class like Microsoft Office for office
automation, Ant virus for the protection of computer against affection/damage,.
With the Disk bootable image different programs are installed in one computer
and then another hard disk is connected to this compute in order to create
image to the hard disk and use the created image to install to other computers.
When doing this to computers with windows XP make sure that you insert the XP
Royal 7 in the disk. This is fast than installing programs to each of the
computers.
Labeling of Network cables
Among
other main activities which were normally done at Tanzania Telecommunication
Company limited was labeling of network cables entering each switch as well as
to the ports they terminate. The main purpose was to simplify the process when
doing troubleshooting of network you exactly know which port/cable/PC has a
problem.
CHAPTER 3
CONCLUSION AND RECOMMENDATION
RECOMMENDATIONS
Ø Shortage of tools for cable
termination such as crimping tool, patching tool which are very much essential
and incase many cables need to be terminated.
CONCLUSION
This DHCP router
configuration is very much important to any of the Organization in which networking is concerned. It is better now to
understand configuration of various types of router including Cisco Router. Configurations
may differ from one router type to another.
CHAPTER 4
PROBLEMS & CHALLENGES ENCOUNTERED BY THE TANZANIA TELECOMMUNICATION COMPANY LIMITED (TTCL)
The Tanzania telecommunication company IT department
is doing the best to make sure it is doing the wonderful job to provide ICT solution
to the municipality. However there are some challenges as one of the department
it encounters.
The
following are the one of them;
Ø I encountered difficult working
as a marketer due the fact that it was new professional.
Ø Sometimes it was difficult to
manage multiplicity of tasks due to time though tried.
Ø suddenly shut down of windows
during installation and monitors non display
Ø Financial shortage as students
most of the time runs bankrupt hence more assistance are required from the
government and other stake holders.
Possible Solutions
Ø Assigning of field supervisors
would be a better approach for academic excellence at TPSC.
Ø Time management it is a
challenge to most of the students but through working hard and putting more
efforts with actual planning its possible.
Ø Juggling multiplicity of
activities is highly encouraged due to the fact that mounts knowledge in
various fields
