CHAPTER # 01

INTRODUCTION TO THE REPORT

I have prepared this report as an essential requirement for the certificate of the internship for the

degree of Bachelors in Engineering (BE Telecom). It has to be written after the completion of six

weeks internship, with the aim to get actual experience and use the knowledge in practical.

1.1 Reason for selecting the specific industry

The Telecom Sector is spreading all over the world and it is going to be the essential part of the

lives of the humans. It is going through a process of rapid change in the world of technology.

In line with global trend and for meeting the emerging demand, major initiatives have been

taken by PTCL too to upgrade its network and also to introduce a range of new value added

services like Broadband and IPTV. And so I have also selected their department of WLL,

Switching & Transmission for my Internship.

1.2 Purpose of the Internship

There are many reasons:

1. To fulfill the requirements for the degree of the B.E (Telecommunication)

From DUE & T.

2. To see the practical world of what we studied during the four years program.

3. To understand how the practical organizations apply the knowledge of the theories.

4. To study the organization for its function and analysis on the basis of the study.

5. To make recommendations on the basis of the study done.

1.5 Hurdles in the Study

I also faced some hurdles during the making of the report. There were so many hurdles but I

mention only those which seems to be important to be discussed here. Some of these hurdles are:

i. No guidance from the university about how to conduct the internship.

ii. The internees are not provided with opportunities of doing things themselves

during internship, making it difficult for them to understand technical things.

iii. Limited Financial and Technical Resources also affected the study. Such as

traveling to customer premises in the field work and the advertising were done by

the internee’s own expense.

Organizational Introduction

CHAPTER # 02

ORGANIZATIONAL INTRODUCTION

2.1Background and History

Pakistan Telecommunication Corporation (PTC) has established in December 1990,taking over

operations and functions from Pakistan Telephone and Telegraph Department under Pakistan

Telecommunication Corporation Act 1991.

PTCL operates in one of the most dynamic, deregulated and competitive markets in the world;

Pakistan with a population of 165 million people is a fast growing economy with relatively low

penetration of Information Communication Technology (ICT) services.

PTCL intends to be the leading ICT provider in the region by achieving customers' satisfaction

and maximizing shareholders' value and as such PTCL perceives its future as a customer centric

organization enhancing its infrastructure and investing in people.

This coincided with the Government's competitive policy, encouraging private sector

Participation and resulting in award of licenses for cellular, card-operated payphones, paging

and, lately, data communication services. In 1994, the PTCL becomes the company limited

(Pakistan Telecommunication Company Limited) by issued six million vouchers exchangeable

into 600 million shares of the PTCL in two separate placements. Each had a par value of Rs. 10

per share. These vouchers were converted into PTCL shares in mid-1996In 1995, Pakistan

Telecommunication (Reorganization) Ordinance formed the basis for PTCL monopoly over

basic telephony in the country. The provisions of the Ordinance were lent permanence in

October 1996 through Pakistan Telecommunication (Reorganization) Act.

The same year, Pakistan Telecommunication Company Limited was formed and listed on all

stock exchanges of Pakistan PTCL launched its mobile and data services subsidiaries in 2001 by

the name of Ufone and PakNet respectively. None of the brands made it to the top slots in the

respective competitions. Lately, however, Ufone had increased its market share in the cellular

sector. The PakNet brand has effectively dissolved over the period of time. A recent DSL service

Section 01 Chapter 02

Organizational Introduction

launched by PTCL reflects this by the introduction of a new brand name and operation of the

service being directly supervised by PTCL.

Pakistan Telecommunication Company Limited had exclusive rights to provide basic telecom

services in Pakistan till the end of year 2002. With the announcement of Deregulation Policy by

the Government of Pakistan in 2003, PTA has issued licenses for basic telephony to the private

sector in Pakistan who will be competing PTCL, the incumbent. From the humble beginnings of

Posts & Telegraph Department in 1947 and establishment of Pakistan Telephone& Telegraph

Department in 1962, to this very day, ours is a story of commitment and vision.

The year 2006-07 in the telecom sector was marked by the phenomenal growth in the mobile

sector in Pakistan, which doubled its subscriber base to 60 million. The teledensity increased

from 26% to 40%, helping to spread the benefits of communication technology across the

country. PTCL ’s mobile phone subsidiary Ufone’s subscriber base grew by more than 87%,

from 7.49 million to 14 million. The year also witnessed the entry of major telecom companies,

most notably China Telecom and SingTel, into market.

The privatization of the company was completed in the 2006, following the purchaser of26% ‘B’

class ordinary shares by Etisalat International Pakistan L.L.C. EIP took over management control

on 12th on April 2006.In short PTCL has been working vigorously to meet the dual challenge of

telecom development and socio-economic uplift of the country. This is characterized by a clearer

appreciation of ongoing telecom scenario wherein convergence of technologies continuously

changes the shape of the sector.

4.1 WLL (Wireless Local Loop)

Fixed line services growth has declined in the World because of the availability of wireless networks

which are easy to deploy and very cost effective compare to the fixed line networks. Further, wireless

based services enabled the customers to avail more innovative services as compare to fixed line. In line

with the world trend, Fixed line telephony in Pakistan has also shown negative growth though wireless

segment has shown positive growth. PTCL has still monopoly over fixed line services along with entry in

Wireless world.

PTCL still has monopoly over fixed line services in Pakistan and share more than 97%subscribers of fixed

lines. However, the fixed line subscribers are continuously declining mainly due to popularity of wireless

based services. PTCL fixed line subscribers in the year 2007-08 declined by about 8% and reached to 4.3

million as compared to 4.8 million in 2006-07. In the year 2007-08, PTCL lost over 402,656 subscribers.

These customers are being transferred on WLL services.

What is WLL?

A wireless loop is a generic term for an access system that uses a wireless link to connect subscriber to

their LOCAL EXCHANGE in place of convectional copper cable. Using wireless link shortens the

Section 02 Chapter 04

WLL (Wireless Local Loop) construction period and also installation cost.

WLL offers high traffic support.

Wireless local loop (WLL), is a term for the use of a wireless communications link as the "last mile / first

mile" connection for delivering plain old telephone service (POTS) or Internet access (marketed under

the term "broadband") to telecommunications customers. Various types of WLL systems and

technologies exist.Other terms for this type of access include Broadband Wireless Access (BWA), Radio

In The Loop (RITL), Fixed-Radio Access (FRA), Fixed Wireless Access (FWA) and Metro Wireless (MW).

WLL technology has been introduced in Pakistan in 2003 where number of licenses has been issued to

various operators for different regions to provide telephony services based on wireless based networks.

Approximately 70% of Pakistan total population lives in rural area which presents huge opportunity for

growth of WLL service because demand for telephony in the country has surged unprecedented.

Regulator is confident that WLL is emerging as a success story in Pakistan and it will help to bridge the

digital divide in Pakistan. WLL service will enable Pakistan to bridge the communication gap by using

cost-effective, easy-to-deploy WLL systems in its rural areas.

Section 02 Chapter 04

WLL (Wireless Local Loop) WLL subscribers are growing exponentially since the launch service in Pakistan in 2003-04. In the year

2007-08, WLL total subscribers reached to 2.2 million with an addition of 537,515 subscribers in fiscal

year 2007-08. However, the growth of WLL subscribers in the year 2007-08 was recorded at 32% where

it was 66% in previous year.

Fixed line telephony in Pakistan has also shown negative growth though wireless segment has shown

positive growth. PTCL has still monopoly over fixed line services along with entry in Wireless world.

As of June 2007 there are about 1.85 million WLL subscribers in Pakistan. Pakistan Telecommunication

Company that works under the trademark PTCL V is the leader with a market share of 59%. TeleCard

(GO CDMA) has 23% of the market. Worldcall Telecom (stock performance; also see coverage on its deal

with Omantel) has 15% share of the WLL subscribers. Great Bear International Services (Pvt) Ltd

(DIALLOG) which is covered here, has 3% share. Even though Diallog is a smaller player, it has been

praised in blogs because of its good customer service and it has higher revenue per user (Rs. 600) than

other companies.

WLL (Wireless Local Loop)

In addition to wireline line operations, PTCL also provide fixed line service through its countrywide

CDMA based WLL (Wireless Local Loop) network, under the VFone brand name. In the Internet segment,

PTCL provides fixed broadband through conventional copper wire & FTTC and wireless broadband based

on EvDO Rev A and B technology with the brand name of EVO.Ptcl has also introduced a 3G tab. In the

cellular segment, the second largest cellular provider in Pakistan, Ufone based on GSM 800/1900

technology, is also a wholly owned subsidiary of PTCL.[4] In addition to these services, PTCL also offers

some of the world's first commercial HD TV services based on IPTV with the brand name of Smart TV and

home surveillance and alarm over broadband under the brand name iSentry. PTCL is also part of the

consortium of three major Submarine communication cable networks: SEA-ME-WE 3, SEA-ME-WE 4 and

I-ME-WE. PTCL offers Pakistan fastest WiMAX connection EVO Wingle at 9.3 Mbps.

Various WLL technologies and deployment options should be evaluated in terms of the following:

Population density of the service area

Connection cost (i.e., equipment and installation)

Level of penetration

Whether the country/area served is developing or developed

TRANSMISSION

5.1 Definition

Transmission (abbreviation: Tx) is the process of sending and propagating an analogue or digital

information signal over a physical point-to-point or point-to-multipoint transmission medium,

either wired, optical fiber or wireless.

5.2 Transmission Technology

Transmission technologies and schemes typically refer to physical layer protocol duties such as modulation, demodulation, line coding, equalization, error control, bit synchronization and multiplexing, but the term may also involve higher-layer protocol duties, for example, digitizing an analog message signal, and source coding (compression).

Transmission of a digital message, or of a digitized analog signal, is known as data transmission or digital communication.

One transmission is the sending of a signal with limited duration, for example a block or packet of data, a phone call, or an email.

The Digital Cross Connect (DXX) system is deployed in the full mesh configuration. The

transmission medium is Fiber Optic. Fiber Optic is the most reliable transmission medium for

long haul communications. Similarly it offers low transmission delays. This enables the

customers to set up virtual private network at very affordable prices. The central nodes of the

network are made up of the 3630 Digital Cross Connect switches from Alcatel, which are

deployed at the Digital Transit Exchanges in all the cities. The 3630 Digital Cross Connect

switches at each Digital Transit Exchange are then connected with the 3630 Multiplexers.

Another important feature of the DXX is that Frame Relay can be employed in the existing DXX

network using FRE and FRS cards in Alcatel 3630 nodes.

5.5 ZNOC (Zonal Network Operation Center)

PTCL is a leading provider of telecom voice and data services within Pakistan. As part of its continuing

infrastructure developments, PTCL has embarked upon a major investment program in the Network

Operations Center (NOC). The purpose of NOC is to control, monitor and manage the entire PTCL

network; to enhance and optimize network management through a transparent and centralized

platform and to create a highly available, adaptable and fault resilient network that can meet market

demand and offer customer satisfaction. Through the NOC, PTCL has been able to address those issues

with a complete convergence of the entire network on a single platform.

There are three types of medias/carrier are used in Pakistan by PTCL.

SECTION 02 Chapter 05

Transmission between the two ends of the fiber. The field of applied science and engineering concerned with the

design and application of optical fibers is known as fiber optics.

Optical fibers are widely used in fiber-optic communications, where they permit transmission over

longer distances and at higher bandwidths (data rates) than wire cables. Fibers are used instead of metal

wires because signals travel along them with less loss and are also immune to electromagnetic

interference. Fibers are also used for illumination, and are wrapped in bundles so that they may be used

to carry images, thus allowing viewing in confined spaces. Specially designed fibers are used for a variety

of other applications, including sensors and fiber lasers.

5.6.1 Construction of Optical Fiber

Optical fibers typically include a transparent core surrounded by a transparent cladding material

with a lower index of refraction. Light is kept in the core by total internal reflection. This causes

the fiber to act as a waveguide. Fibers that support many propagation paths or transverse modes

are called multi-mode fibers (MMF), while those that only support a single mode are called

single-mode fibers (SMF). Multi-mode fibers generally have a wider core diameter, and are used

for short-distance communication links and for applications where high power must be

SECTION 02 Chapter 05

Transmission transmitted. Single-mode fibers are used for most communication links longer than 1,000 meters

(3,300 ft).

Joining lengths of optical fiber is more complex than joining electrical wire or cable. The ends of

the fibers must be carefully cleaved, and then carefully spliced together with the cores perfectly

aligned. A mechanical splice holds the ends of the fibers together mechanically, while fusion

splicing uses heat to fuse the ends of the fibers together. Special optical fiber connectors for

temporary or semi-permanent connections are also available.

5.6.2 Types of optical fiber cable

Optical fiber cable is available in three forms which are

1. Slotted core cable

2. Loose tube cable

3. Loose tube slotted core cable

5.6.3 Main Application of the optical fiber cables

.Public and private telecommunication lines

.Computer network (LAN, WAN )

.Television distribution network (CATV)

.Military network

.Control, remote control & signalizing network

.Video supervision lines

SECTION 02 Chapter 05

Transmission

5.6.4 Advantages of the optical fiber cables

Optical fiber cables are not affected by any interference originated from energy transmission lines.

Radio waves and cross talk between the fibers does not exist. No special protection is necessary.

1. Non Conductivity

No grounding is necessary because of metal free cable.

2. Large Wide bandwidth

Suitable for high speed. Wide-band, telecommunication lines.

3. Low Loss:

Because of Low few or no amplifiers are necessary.

4. Very Light Weight

The smallest cables can be designed and manufactured therefore reduce pulling strength and reduce

laying cost.

5. Economic

The most economical solution for the simultaneous transmission of several multichannel users.

6. Low Attenuation

7. No Cross Talk

8. Many channel Capacity

9. Easy Installation

5.6.5 Optical fiber cable used in Pakistan

1. Olex cable (18 fiber slotted core number of slot 6) 2. Fujikura cable (18 fiber slotted core number slot 10) 3. Siemen cable (12 fiber loose tube) 4. LT Engineering cable (18, 12, 6 fiber loose tube with slotted core)

SECTION 02 Chapter 05

5.6.6 Ring Topology

INTERFACE

A ring network is a network topology in which each node connects to exactly two other nodes, forming a

single continuous pathway for signals through each node - a ring. Data travel from node to node, with

each node along the way handling every packet.

Because a ring topology provides only one pathway between any two nodes, ring networks may be

disrupted by the failure of a single link. A node failure or cable break might isolate every node attached

to the ring. In response, some ring networks add a "counter-rotating ring" (C-Ring) to form a redundant

topology: in the event of a break, data are wrapped back onto the complementary ring before reaching

the end of the cable, maintaining a path to every node along the resulting C-Ring. Such "dual ring"

networks include Spatial Reuse Protocol, Fiber Distributed Data Interface (FDDI), and Resilient Packet

Ring.

for prepaid calling cards and provision for introduction of new services.

To further support the launch of new services the optical fiber junction access network

has been in implementation phase. This system further supports the upcoming project of

PTCL WLL (wireless local loop), Broad Band Services & IPTV. Network Operation

Center (NOC)

(Pakistan Telecommunication Company Limited, Oct-Dec 2008, pp. 21-22)

Pakistan Telecommunication Company Limited (PTCL) is a prime provider of telecom

voice and data services within Pakistan.

As Part of its ongoing infrastructure development, PTCL has embarked on a major

investment program in a Network Operations Center (NOC).

SECTION 02 Chapter 06

Fig. NOC application launched

The purpose of NOC is:

To control, monitor and manage the entire PTCL Network

To enhance and optimize Network Management through a transparent and

centralized platform

To create a highly available, adaptable and fault resilient network that can meet

the market demand and provide customer satisfaction

Due to the absence of a NOC, PTCL currently faces serious operational challenges:

Since there is no centralized network management, fault resolution is ad hoc and

inefficient, service restoration takes a long time

There is no mechanism for root cause analysis

Through the NOC PTCL have been able to address these issues with:

A complete convergence of entire Network on a single platform

Proactive identification and resolution of faults through:

Real-time Network Monitoring & status visibility.

PTCL have been able to increase network availability through:

Enhanced Quality of Service and centralized performance statistics and

reporting mechanism.

SECTION 02 Chapter 06

Through escalation policies, work orders and maintenance of secure

activity logs

A Fault resilient and highly

available Network is a direct

result of NOC. However the

NOC platform has also been

used to diversify the services and

customer base to increase

revenues. NOC has been used

for:

Modifications of SOPs for:

DSL, IPTV, Triple Play provisioning and complaint handling.

BNCC has been integrated for resolution of complaints reported by the

customers.

NOC is used for provisioning of SLA support for all domains.

Management of DXX corporate customers and outsourced Data Centers.

Further, Performance management statistics are being used to conduct a trend analysis

and reengineer the network.

Fiber Cut Scenario

On average PTCL experience hundreds of fiber-cuts in a month. As a result PTCL have

automated the root cause analysis process for this scenario:

When the system detects a fiber cut a siren goes off, cable cut blinks on the screen and

hundreds of critical alarms pop up on the screen, the correlation rule kicks in and the

alarms are associated and consolidated into a single root cause alarm.

A TT is automatically generated

identifying the affected cable

section between two NEs.

An automated notification is

dispatched to the responsible

coordinator via time stamped SMS

and EMAIL. The coordinator then

issues a work order for fault

resolution. IOf the fault is not

resolved, verified and closed

within a stipulated time frame, the

escalation process is triggered and

senior management is notified with an SMS and email for appropriate action.

Complete visibility of the network, intelligent root cause analysis and defined SOPs for

work order dispatching and escalation are the core tools that shall allow the NOC to

provide a robust network making PTCL a landmark of excellence in the world of telecom

CHAPTER # 07

FINDINGS AND RECOMMENDATIONS

In this chapter, I am going to discuss the findings and my view of recommendations which I

faced and thought during the internship. These findings and recommendations will help the

organization to serve the customers in a better way and will enhance their capabilities of

performing earning and they will get the high value than those upcoming competitors of it.

7.1 Findings

Below are some of the observations which I did during my internship duration. I mention it here

for the purpose to enhance the capabilities of the organization of my Area if these are considered

by the managers. They will also have an edge on the upcoming competitors of them and will not

let them loose their potential customers.

No proper theory references on related topic for courses.

The employees were not trained enough and were not having enough knowledge about

the work they were performing.

Less educated staff reduces the performance growth of the department in general and of

the organization as a whole.

Lack of time Punctuality of workers and employees.

No full co-ordination with the other departments.

No proper procedure of installing new connections due to which the complaints increase

and also some customers lose their confidence in the Broadband connections.

Internees were performing all the travel.

Lack of computer knowledge of well designated employees.

Section 03 Chapter 07

Findings & Recommendations

7.2 Recommendations

No doubt P.T.C.L having the monopoly in providing the Land-Line Telephone

connection in Pakistan and its playing its role magnificently. In current scenario P.T.C.L

has increases its Revenue quite dramatically and probably that as soon as this

organization has become privatized it will flourish its revenue in better manner.

PTCL should immediately change its Finance upper level of hierarchy and should stream

line in the good manner.

PTCL should also encourage the Billing On line system that each and every customer

should have to pay his/her bill on line basis..

The image of PTCL being leading Telecom providing is not good in the eyes of common

customer especially there are lot of complaints about the including the bogus local calls

in the monthly bills of various customers. PTCL should also provide the detail of local

calls made from any Land Line Number which would be provided in Micro level to the

customer.

Should be decreased the over number of employees.

Should be developing the training and development process of every employee.

The punching system of Billing through automation attach with main branch he takes so

much time to adjust so it should be revived.

PTCL is not utilizing its surplus profit in long-term investment projects which be done.

PTCL management should give higher better gate keeper and keep close eye on

attendance and existing and leaving time of employees.

The return on deposit should be checked accordingly.

The cash generated from the operation must be utilized accordingly.

Each Region should allocate the funds at its own level.

PTCL should take the services of highly qualified engineers to use the resources and

material dumped and recycles it.

Section 03 Chapter 07

Findings & Recommendations In every organization; In PTCL this is not going well. So there is an immense need to

improve this department. Better working environment for all.

The promotion system in the Finance & Revenue wing should be revived in true manner

All promotion must be made strictly on merit, Promotion polices should be clear.

Each Region should maintain Profit & Loss and Balance sheet and the statement of Cash

inflow and outflow.

Hundred percent computerization in PTCL would be helpful to save the time and money

and provision of quick services to its valued customers.

Human resource development is a key component

Section 03 Chapter 08

Conclusion

CHAPTER # 08

CONCLUSION

No doubt PTCL is enjoying monopoly but the time is came when competition will force

Company to change its policies to become favorite telecom service provider in the Market &

keep its current place & customer base.

The company maintains a leading position in Pakistan as an infrastructure provider toothier

telecom operators and corporate customers of the country. It has the potential to be an

instrumental agent in Pakistan’s economic growth. PTCL has laid an Optical Fiber Access

Network in the major metropolitan centers of Pakistan and local loop services have started to be

modernized and upgraded from copper to an optical network On the Long Distance and

International infrastructure side, the capacity of two SEA-MEWE

Submarine cable is being expanded to meet the increasing demand of International traffic. PTCL

should immediately change its Finance upper level of hierarchy and should stream line in the

good manner. PTCL encourage the Billing On line system that each and every customer has to

pay his/her bill on line basis.

The system of E-PAYMENT which although exist in PTCL finance system but there is need of

improvement this facility.

The image of PTCL being leading Telecom providing is not good in the eyes of common

Customer especially there are lot of complaints about the including the bogus local calls in the

monthly bills of various customers. PTCL also provide the detail of local calls made from any

Land Line Number which would be provided in Micro level to the customer. Faulty Telephone

connection Fault Free within 24 hours in order to maximize the Revenue, as Revenue of PTCL

should sacrifice at the cost of Faulty Telephone. PTCL should make Customer Care Centers in

remote areas.

Section 03 Chapter 08

Conclusion

I have to express my experience of internship in PTCL I would briefly say:

PTCL is a good Organization in the way that anybody can join it for his/ her long-term career.

Overall working environment is comfortable. Management of branch cares a lot of its employees

and considers them as the Asset of PTCL. Behavior of senior executive of bank is very polite and

they are caring about the individual’s career and their growth. PTCL needs innovative service

offerings — currently it doesn’t even offer bundles or a single bill.

It is said that the best assets of a company go home to their family in the evening. Can the culture

of PTCL be changed to a performance and service-based organization?

According to the latest director’s report from PTCL the “organization is being revamped”. Only

time can tell the impact. However management is very demanding about the targets but good

reward at the achievement of assigned targets is awarded.

Employees at PTCL are quite efficient. Its employees have to bring their org among the list of

good. It also shows their loyalty, commitment to organization.

Employees are given the benefits like bonus, gratuity funds, loans, increments, and medical. All

the customers are entertained individually. Same kind of behavior and attention is given to all the

customers. Getting ideas for improvement from customer side is a new idea and that is working

very well in PTCL. All the customers are asked to fill a suggestion form and the standards of the

org are improved through them. So far my learning is concerned; all the employees at branch

were quite cooperative. They helped me to understand the activities of a org to possible extent.

Their good attitude gave me more confidence to learn more and to ask if I have any query in my

mind. Besides there ever going activities they never get irritant by my questioning. I had made an

honest efferent to present the working & operation of PTCL in simplest way.

I feel pleasure that I have really gained a lot during 6 weeks & enjoyed working with

experienced cooperative & intelligent staff.
