regional division, where duties were assigned providing the experience as a product
specialist .Over the course of internship a variety of activities were experienced, both
technical and process related .This provide a range of valuable job skills which would be
able to applied in future position both with Ethio telecom and western region division in
general.
2. Background of Ethio telecom

The introduction of telecommunication in Ethiopia dates back to 1894.
Ethiopian Telecommunications Corporation is the oldest public telecommunications operator in Africa. In those
years, the technological scheme contributed to the integration of the Ethiopian society when the extensive
open wire line system was laid out linking the capital with all the important administrative cities of the
country. After the end of the war against Italy, during which telecommunication network was destroyed,
Ethiopia re-organized the Telephone, Telegraph and Postal services in 1941. In 1952 the Imperial Board of
Telecommunications (IBTE) was
established by proclamation No. 131/52 in 1952. The Board had full financial and administrative autonomy and
was in charge of the provision and expansion of telecommunications services in Ethiopia.
The Imperial Board of Telecommunications of Ethiopia, which became the Ethiopian Telecommunications
Authority in 1981, was placed in charge of both the
operation and regulation of telecommunication services in the wake of the market
reforms. In 1996, the Government established a separate regulatory body, the Ethiopian
Telecommunication Agency (ETA) by Proclamation 49/1996, and during the same year, by regulation 10/1996,
the Council of Ministers set up the Ethiopian
Telecommunications Corporation (ETC).
Recently, the Ethiotelecom company has been organizational structured by 1 head quarter,6 zonal offices and 8
regional offices providing different services such as fixed telephone, mobile telephone, internet, CDMA, etc
through its offices .Western region is among 8 regional office and plays vital role in ethiotelecom on behalf
of it self.

3.Management, Training and employee
information
 Ethiotelecom has different departments in different places. Here, at western region we assigned
to work in operation and maintenance department for all internship session. This section
covers all operation and maintenance case of western region. So that, it consist of seven
different working section. At the day we began intern to this region we introduced with
operation and maintenance manager and he assigned a supervisor for us. On the next day, after
we have introduced with our supervisor and he shown us different working sections of this
region and supervisor assigned us to work with their coworkers.
 We introduced to the supervisor and with other operation and maintenance worker for two
weeks first. After that, we assigned to see different western regional Ethiotelecom equipments
and how they are configured these includes RAN system, transmission system, exchange,
routers, PSTN, BSCs, BTSs and the like. To have detail knowledge about this equipment the
manual of some equipment is give for us by pdf and by hard copy/module/.After we have
completed these duties we are assigned to see all operation and maintenance section turn by
turn. First turn RAN section, second turn core section, third, fourth, fifth IP section,
transmission section, payphone section respectively. Finally we are assigned to see power
section. For each section we are assigned to work for more weeks.
Our supervisor has helped us to succeed in our assignments in a good manner. After we
encountered about a week one personal computer is given for us from his working section.
There are free internet access about 100Mbps and we have used for reading and checking
our account and such a like. Our supervisor guided us what we have to do and what we
haven’t do in our daily working at every working time and he took attendance to follow us
whether we present or not. We ask our coworkers if there is unclear thing while we are on
working.
The other responsibility we had during our internship is respecting working ethics like
arriving on time, cooperation with coworker, accepting and respecting daily duties given by
our supervisor and the like.
Western region has many workers in different departments. It is difficult to mention all
departments on this report because of its wideness but, let us mention the main department
of this region.
1.Operation and maintenance department
This department deals with all operation and maintenance of RAN, corenetworks,
transmission, exchange, PSTN, payphone equipments sothat, this department is
back bone at this level.
2.Fixed access network department
Does the operation maintenance activities of copper cables and optical fibers.
3.Human resource management department
This department manages human power with the intention that, employee appraisal
is conducted once a year for employee and managers and also used two types of
standardized forms i.e, administrative and clerical, and management and
professional performance evaluation format respectively. Progress of employee
performance is measured periodically, provide feedback and support employees to
achieve both quantitative and qualitative targets.
4. Specific job information
4.1 operation and maintenance department
4.1 .1 Radio Access network System (RANS) section
 In this section we have seen different types of BTS, BSC
different vendors’ equipments. That equipment plays their
own role for mobile communication. Let us discuss in
short and brief.
Base transceiver station (BTS): BTSs-houses the radio transceiver of the cell and handles
the radio links protocols with the mobile
-connects to a number of mobile stations (MSs) and each MS establishes connection through the
user interface um where um is the ISDN U interface for mobile.
-A BTS is also connected to a BSC at through the Abis interface which transmits and
receives data. With four multiplexed channels of 16 kbps or with a 64 kbps channel.
In this section we seen two BTSs.
one BTSs operates to 900MHZ which is corresponds to out side nekemte town for rural areas of
nekemte town.
The other BTS is operates to 1800MHZ which is used for nekemte town. These BTSs is
corresponds to GSM. Similarly two CDMA’s BTSs is found in this section which is operates to
frequency of 800MHZ and450 MHZ which is used to cover town and rural area of Nekemte
respectively.
Main function performed by the BTS
Formation of cells using appropriately directed antennae
Processing of signals
Amplification of signals to acceptable strength so that they can be transmitted without loss of
data.
Channel coding and decoding (for example, coding voice into bits so that it can be transmitted at
13kbps and decoding received coded signals back to voice).
Frequency hoping so that multiple channels for various mobile stations can operate
simultaneously using different channel band frequencies
Base station controller (BSC)
In this room there are three racks serves for BSC which is used to control western regional
ethiotelecom BTSs and it manages radio resources (channel set up, hand over)for one or more
BTSs.BSC connected to an MSC in the networking and switching layer using an interface A.
Important functions performed by the BSC
•Processing of signals
•Controlling signals to the connected BTSs and control of handover of signals from one BTS to another
with in a BSS
•Control of handover of the signals from BSC to MSC(Mobile switching center)
•Mapping a signal of a channel at a given instant receives signals from a BTS at 16 kbps through and
interface to MSC at 16 kbps
•Alternatively, may have to interface to a PSTN switching centre at 64 kbps through a fixed line network
•Reserving radio frequencies and frequency hoping(For example, multiple BTSs operate simultaneously
by using the different frequencies at a given instant)
•Location registry for the MSs
•Authentication, encryption ,and decryption of data
BSC and BTS maintenance system
Daily routine maintenance: this includes
1. Equipment environment:-This includes temperature requirement 15oc_30oc.
2. Equipment running status:-This can be
a. querying the alarm information
b. running status of boards:-It is required to check whether the indicators for each board in the rack
are normal. If any alarm indicator is on, it is required to maintain and eliminate the fault. By the different
flashing meaning of the indicators’ we can determine the running status of the equipment.
Regular routine maintenance:-This can be considered as
1. Checking BTSs and BSC rack modules:-checking the amount, model and version of the spare
modules once a week.
2. Hardware checking:-This includes cleaning the rack, checking
power cables and ground cables
Typical maintenance method:-In daily maintenance, several typical maintenance methods can be used
as follows:
1. Observation method:-Locating the fault by viewing the alarm information of the LMT of the BTS.
The observation method is the first method the maintenance personnel should use in case of fault
occurrence. Making a correct judgment on the observation result is a key step for correct analysis and
handling of the Fault. Therefore, the maintenance personnel must be very familiar with the indicator
statuses of the boards, and fully aware of the meanings of the alarm information of different levels on
the LMT of the BTS.
2. Plugging/unplugging method:-When a circuit board is initially found faulty, plug/unplug the circuit
board and the external interface
connector to eliminate such faults as poor contact or processor abnormality. Make sure that the board
must be hot-swappable when this method is applied.
3. Replacing method:-The replacing method is to check the fault by replacing the circuit board in
question with a normal circuit board. When the plugging/unplugging method fails, the replacing method
can be applied.
4. Isolation method:-When a part of the system is faulty, the involved circuit board or racks can be
isolated to check whether the fault comes from mutual impact. For example, a typical application of the
isolation method is to self-loop the I/O interface of a circuit board so as to isolate and solve the problem of
the related system.
5. Self-test method:-When the system or circuit board is powered on again judge if there is any fault by
way of self-test.
Usually, when a circuit board is re-powered on for self-test, the indicators on its panel will flash
regularly, so that we can check whether the circuit board itself is faulty.
6. Pressing method:-Such faults as poor contact can be removed by pressing the chips and cable
connectors.
4.1.2 Transmissions, access and transport section

The ethiotelecom objective is to produce high-quality voice, video, and data
Communication between any pair of desired locations, whether the distance between locations is 1 or
10,000 km. The distance between the two locations
 determines the type of transmission equipment used for setting up the
connection. First, communication over a distance on the order of a few meters, such as within a building, is
done using metallic wires, optical fibers or radio. Any routing of information within the building is done by
switch on the premises, a switch known as a private branch exchange (PBX).When the distance is extended
to a neighboring building or to span a distance within a village, town, or city, the local telephone network is
usually used. This entails making a connection to the nearest switching exchange by
a pair of copper wires or radio, routing the initiating party to the desired receiving party, and completing the
connection on the recipient’s pair of copper wires, or radio, which are also connected to the nearest
exchange. The next stage of interconnection is intercity or long-distance, connections. The contenders to fill
this role are microwave radio, optical fiber, and satellite. Fierce competition has emerged among these three
technologies. Microwave and satellite communications are far more mature technologies. For wideband
services optical fiber will no doubt be used in the future.
 There are many other instances where the choice between microwave radio
and optical fiber systems are not so clear. The decision might be in favor of
satellite or microwave radio for very rugged terrain, or fiber optics for very
flat terrain. When the region under consideration contains both very flat and
very mountainous areas, a combination might be suitable.
In addition to above, we have seen various transmission system used to transport information
from one place to other place. Let us see one by one.
1. Microwave
Microwave communication is the transmission of signals via radio using a series of
microwave towers. Microwave communication is known as a form of "line of sight"
communication, because there must be nothing obstructing the transmission of data between
these towers for signals to be properly sent and received .Additiionally, we have seen
different types of microwave dishes directed to different microwave repeaters. This
microwave repeater increases the power gain which will be transmitted from BSC. So that,
there are several microve repeaters available for this region.
Fig 4.1
long-distance paths. In this illustration, a large number of customer signals (around 2000) are
multiplexed together into a single signal, ready for transmission over the microwave link. The signal is
converted to the microwave frequency (around6 GHz) and transmitted over a path of typically 30 to 60
km from station A to the receiving antenna at the repeater station. The repeater either (1) simply
amplifies the signal and sends it off on its journey using a different micro wave frequency to minimize
interference, or (2) it completely regenerates the individual pulses of the bit stream before reconverting
the signal back to a microwave beam for onward transmission. Station B receives the microwave
signal, processes it, and unravels the individual channels ready for distribution to the appropriate
customers at these end users.
2. Fiber optics
Fiber-optic communication is now the dominant data transmission method. However, microwave
communication equipment is still in use at many remote sites where fiber-optic cabling cannot be
economically installed.
At present cisboarder backbone network is microwave transmission system, as telecommunication
service is becoming in Ethiopia.The existing back bone transmission system cannot meet the needs of
the people. Therefore ETC confirmed eight optic fiber lines through out the country to be builted; its
main aim is to resolve communication problem of communication between country capital and states.
This Nekemte branch includes eleven stations(Addis Ababa, Holota, Adis
Alem,Welenkomi,ginchi,Ambo,Guder,Gedo,Ijaji,Bako,Sire and Nekemte).This Nekemte branch also
extended up to Asosa regions by branching to different western regional towns. Here one SDH 2.5G
and one SDH 155M system is equipped in the route.
All optical fiber out from or into all stations terminated at the termination box on the
ODF. The termination box connected to flange; using single ended pigtail fibers, and
connected to SDH equipment using dual ended pigtail fibers with FC/PC. The 34Mbits/s
(E3) or 2Mbits/s (E1) port of SDH equipment connected to DDF in the equipment rooms.
Using coaxial RF cables. The 155M outlet fibers of the branches terminated on ODF in the
transmission rooms, using dual ended pigtail fibers with FC/PC. In this transmission
system communication cables includes trunk cables, pigtail fibers, clocking wire and alarm
wires and network wires. All these cables run in cable trays and placed in order and bound
fitly
3. VSAT (Very small Aperture Terminal)
Two Stations on Earth want to communicate through radio broadcast but are too far away
to use conventional means. The two stations can use a satellite as a relay station for their
communication. One Earth Station sends a transmission to the satellite. This is called a
Uplink. The satellite Transponder converts the signal and sends it down to the second
earth station. This is called a Downlink.
The Broadband VSAT is a satellite system especially applied to the remote areas of the country. The
country uses the Broadband VSAT network for the provision of triple play services for high schools,
universities, research centers, Woredas and Non Governmental organizations.
School Net: with the aim of providing similar standard education to high schools throughout the nation,
the program was launched in February 2004. At this time 1093 high schools and preparatories are
getting the service with the help of 12 channels; in addition to this the 197 of the high schools have got
access to internet service with a capacity of 256kbps.
WoredaNet: The WoredaNet Network has enabled woreda centers of the country with the opportunity
to use voice, data and multimedia services. At this point in time 631 woredas are getting data, internet
and Video conferencing service with a maximum capacity of 512kbps.
AgriNet: This AgriNet Network has a total of 35 VSAT stations which are agricultural institutions
connected with each other and the federal government for Internet service.
The advantages of satellite communication over terrestrial communication are:
The coverage area of a satellite greatly exceeds that of a terrestrial system.
Transmission cost of a satellite is independent of the distance from the center of the coverage
area.
Satellite to Satellite communication is very precise.
Higher Bandwidths are available for use
The disadvantages of satellite communication:
Launching satellites into orbit is costly.
Satellite bandwidth is gradually becoming used up.
There is a larger propagation delay in satellite communication than in terrestrial communication
4.1.3 Internet protocol (IP) and IT section
 Ethio telecom’s IP Network is constructed in such a
way that it can provide NGN (including GSM, Fixed
NGN, CDMA, IP/Broadband Access Network services
including Value Added Services) at regional cities,
major cities, sub cities, and towns. To understand
easily this IP network let us show you its topology.

IP network layers and their functions
1. Gateway layer: This layer deployed in four sites and contains routers mainly functions to connect to an
external network /internet/
The Ethio Telecom has built extensively Ethiopia’s internet infrastructure to give better and quality
internet service. Currently; we have fifteen international internet links from Bole, Bahirdar Diredawa and
Shashemene gateways. The Total Upstream /downstream bandwidth is 6475.5/6775.5 in Mbps
2. Back bone layer: Totally 10 sets of BR (T8000), distributed to five cities and each city deploys two
sets of BR, full meshed connection. This layer is mainly responsible for service traffic forwarding and
high capacity communication facilities.
3. Core layer: This layer is mainly responsible for service traffic forwarding,
convergence and high capacity communication facilities.
4. Edge layer: Provides information exchange b/n the access and core network. It is an entry point in to
carrier/service provider core backbone networks and used for aggregation of core switches
•5. Acess layer: Access layer is where broadband access devices and ethio telecom’s other networks (GSM,
CDMA, FL-NGN) are connected.
4.4. Core Network, Local Switch and MSAG Section





Core network: A core network is the central part of a telecommunication network that provides various
services to customers who are connected by the access networks. One of the main functions is to route
telephone calls across the PSTN. Typically the term refers to the high capacity communication facilities that
connect primary nodes. Core/backbone network provides paths for the exchange of information between
different sub-networks
Core network includes three parts:1. Soft switch: A soft switch has revolutionized telecom industry. Gone are the days of conventional voice
switches. These days, a soft switch can work with voice, fax and video, contributing much to the recent
telecommunication revolution. As a matter of fact, a soft switch is a virtual device/software that connects
calls from one line to another. Since this is a virtual tool, it is entirely managed via computer.
2.Media gate way: A Media Gateway acts as a translation unit between disparate telecommunications
networks such as PSTN; Next Generation Networks; 2G, 2.5G and 3G radio access networks or PBX.As the
Media Gateway connects different types of networks, one of its main functions is to convert between the
different transmission and coding techniques.
3. Public switching telephone (PSTN):-The basic service of PSTN refers to the basic call connection
functions provided by the switch, inter office call, local call, national toll call, international toll call, tendem
call and others.
MSAG:-MSAG (Multi-service Access Gateway), a reliable device of medium capacity and carrier class
rolled out by ZTE, mainly develops VOIP services and broadband data services over the IP MAN or
backbone network, and is primarily based on the accessing of ADSL or VDSL to realize the voice and
data services simultaneously. Also, it can access the corporate users like enterprises by deploying the
inner LAN to provide IP phone services.
Local switch:-Is the telephone exchange in the PSTN directly serving subscribers. This serves includes
dial tone, calling, features and additional digital and data services to subscribers using the local loop.
4.1.5 Pay phone and CPE section



CPE:- A customer premises equipment device (CPE device) refers to a telecommunications hardware device
located on the telecommunication customer's premises. This equipment might include cable or satellite
television set-top boxes, DSL or other broadband Internet routers, VoIP base stations, telephone handsets, or
other customized hardware. CPE equipment can be owned by the customer or leased from the
telecommunications company. CPE also includes the interior wiring at the customer's location that is
connected to a communication service.
Payphone:- payphone is a public telephone, often located in a telephone booth or a privacy hood, with prepayment by inserting money (usually coins), a credit or debit card, or a telephone card.
Ethiotelecom facilitated the communication system as a form of payphone for rural, towns and cities of
Ethiopia. Here fixed telephone, GSM, CDMA can be considered. The quality of this payphone is that; since
it uses solar power it is very useful for rural areas of Ethiopia where difficult to get AC power source. Now a
days rural areas of Ethiopia (kebele and wereda) uses this wireless CDMA, GSM payphone and easily can
access communication networks.
4.1.6 Power and environment section

This section is one of the important parts of the ethiotelecom division section. The main job of this section is
managing and facilitating power supplies for this environment. Especially for equipments. To do this in a
best condition this section uses different equipment and limit power specification of equipments.This
equipment includes:1. HF- switch:-380v triple-phase with five lines and 220v single phase with three lines can be
Can be accessed.
-frequency: 50HZ
-lighting protection added
-warning of high voltage and AC failure; marking civil power and generator.
2. AC power supply:-This includes generators and hydro electric power
3. Rectifier: - AC 220V input; DC -48V out put
-function of floating charge, averaging current, converting
-warning of high and low voltage
-Adjusting scope of DC voltage output: -50V--59V
-Adjusting scope of equalize voltage: -50V-60V
4. DC power supply system:-warning of DC high voltage output, low voltage output and without
-Two times discharging and battery low voltage protected.
5. Non maintenance storage battery:-low self discharge

-flow and equalize charge of battery is in constant voltage
-the steel antiseismic rack or stand rack is used to fix the storage batteries.
During our internship period the responsibility given for us is covering all operaration
and maintenance department sections and we have successfully seen all these section
accordingly which is crucial for our stream.
We were in trouble when we were working in core network and transmission section
while fiber optics and telecommunication course is a base for this sections.Therefore,
to be succeful in our practice we decided to read manual and soft copy after that we
continued practical work.
The other course we advanced while we on intern are Antenna system and design .it
is also the basic in some of antenna related like MSAG ,BTS ,BSCs and the like
configurations .The other one is Electromagnetic wave and propagation is also the
basic one for such alike work, Every wave can move from one any type of antenna to
another in the form of Radio wave ,microwaves and fiber optics to transmissions and
receiving
5. Evaluation and critique



Today all of the worlds are becoming to one neighbor district through globalization and technology
development in high speed, if you need any things from this world there is a competition beside of you.
Therefore to become a competent of as such you have to know in every directions around that you are
focusing for .Internship is the basic knowledge full for every students living in this globalized world. There
is knowledge at every work industry the same as that of at school, even if there is a problem with some
industries to give you a chance for more working accessibility intern students can get more knowledge more.
So we are one of that! we got more knowledge related to our field from this company and we also know the
working behavior, in general as we already explain it so far what we got from this intern. Any like explained
above problem can be solved by the Universities or collages internship committee or other concerning parts
for his trainees benefit to get productive human from this career, unless it is just merely losing a country
resource and human mind. We extremely blame especially electrical department Intern holder. We never ever
visited whether we on working or not. Every intern owner must have to follow and communicate to help his
trainees at every time needed. As such is so worthy!
Finally, since modern technologies is dynamic to go with recent technologies any education should be
supported by education tour for each related course .To do so, the university should facilitate education trip
in addition to internship.
5.1 Recommendation
Now we would like to recommend the internship to be improved as internship
student from what we face when we are on intern.
First of all the university must have facilitate the place of internship for his
student strictly that is favorable to follow them while on work. There was a
problem with our university concerning this in fact. Most of intern students
are searching company by them selves with some challenges we know.
The internship students must have followed in related by the University
advisors at least once per month. The problem we mentioned above favorable
is here useful for our advisors to perform this actions easily.
The internship student must be evaluated or have a report what they have been
working every months in the form of hard copy or through e-mail to university
advisors. Also there must be a neat communication between the Organization
and University advisors to do this type of evaluation.
Every help and supports are throughout the duration of internship placement is
strictly required from every department internship concerning body.
Finally; in our report we wanted to describe the topology of Nekemte BSC but
because of shortage of available space we haven’t described on this report.
