OBJECTIVES OF PROJECT

One of the first steps in learning that how this system actually goes on and one is to understand

the various components involved in this technology and QUADRANT TELEVENTURES

LIMITED CHANDIGARH is one of the best, rather i would say ideal place, to have a look into

the same and especially when the place has got a state-of-the-art infrastructure, it is really a

privilege to be over here.

Being a Electronics & Communication Engineering student, it is very important for me to know,

in detail, as how actually does this technology work at such a mammoth level. Also i have got a

personal keen interest in learning every bit about the telecommunication. So the main objectives

of training here is: -

1. To familiarize ourselves with all the main telecommunication technologies i.e.

Switching

Optical fiber communication

Mobile

Broadband services

ISDN

DSL and ADSL

Leased lines

2. So as to get exposure to the working/live telecommunication equipment deployed in

CONNECT TELECOMMUNICATIONS.

3. To prepare myself for selecting the areas of their choice to enter in the

telecommunication industry.

4. So that i can learn more about the changing technologies in telecom industries and their

future aspects.

5. So that i can learn basics about telecom very well.

INTRODUCTION TO PROJECT

In this project mainly we have created a network between two cities say Chandigarh and

Amritsar. We have made use of routers and switches to create a network. My main aim is to

manage and troubleshoot the problems that occur in this network and upgrade the preexisting

sites as the traffic increases on them.

The job assigned to me is FIELD WORK. I look after the network of Mohali and 2 nodes are

under my supervision.

As in the field work the work allotted to us is following:-

1. Operation and Maintenance of existing NODES.

2. Installation of new NODES.

NODES (ACCESS NETWORK)

What is a NODE?

NODE is a small exchange, which provides basic telephone services to the Customers and is act

a link between customers and switch. It is also called access network and these access networks

are connected with each other through transmission equipment’s.

Access network is the network connecting the subscribers to the central office i.e. it forms an

interface between the exchange and the subscriber.

It deals with the physical connection (or termination) of subscriber lines. It is also responsible for

testing of digital lines and transport of subscriber speech data and subscriber line signals.

Basic elements of NODE (ACCESS NETWORK)

ONU 160B, ONU60A, FO2A

ANYMEDIA

DSLAM (ATM, IP), MSAN

TRANSMISSION EQUIPMENT

FMS

DDF

MDF

DATA MODEMS

POWER PLANT with BATTERY BANK

QUADRANT TELEVENTURE NETWORK’S CONNECTIVITY

DESIGN OF SOLUTION

Put the various elements in an existing ring.

Replace the faulty elements in a NODE.

Give the particular E-1 signal to various elements in NODE.

Check the various alarms at the NODES at regular intervals.

Regular expansion of the various cards in various equipment’s. If there is any LOS (loss

of signal) at any NODE then check the fault and recover it.

Study of SDH technology.

Study of DSL technology.

Study of DATA links.

METHODOLOGY ADOPTED

To get the whole knowledge about the project and related work so we have divided our training

to following phases:

1. Theoretical knowledge about each and every component in the NODE.

2. Getting knowledge from the work that node engineer does when any kind of fault

occurs in the node.

Configuration and installation of various Components like

ONU 160B,ONU60A,FO2A

ANYMEDIA

DSLAM(ATM,IP),MSAN

TRANSMISSION EQUIPMENT

FMS

DDF

MDF

DATA MODEMS

POWER PLANT with BATTERY BANK etc.

3. Theoretical study of projects

4. Testing and implementation of project.

5. Preparing the training report timely.

BENEFITS FROM TRAINING

The basic scope or we can say the aim of the training is putting our theories to practice. What we

have learned in four years of the B.E. degree, is put to practice. Anything we just learn as a

theory subject, we will forget that thing very quickly, but if we will put that thing to practice we

will not forget that thing in our whole life. It is not possible for a single college to provide the

practical training for all the 350 students because it is too costly to provide such machines or

systems that a multinational company can provide to the trainees. I am doing my six month

industrial training at CONNECT QUADRANT TELEVENTURES LIMITED Sec-35 Chd. It

will be a great experience to work with such great and intelligent colleagues. Other features of

training are:

Seamless integration

Real-time training for a dispersed class using just their components and instruments.

Practical Knowledge of subjects that we have studied in our degree.

To get knowledge in detail, as how actually does this technology work at such a mammoth

level in a ring topology.

Project development as per industry quality standards: Since CONNECT is a brand name

thereby the project undertaken and its implementation would meet the required industry

standards.

LIMITATIONS

ASYMETRICAL DSL SERVICE

ADSL is a distance-sensitive technology. As the connection's length increases, the signal

quality decreases and the connection speed goes down. The limit for ADSL service is 18,000

feet (5,460 meters), though for speed and quality of service reasons many ADSL providers place

a lower limit on the distances for the service. At the extremes of the distance limits, ADSL

customers may see speeds far below the promised maximums, while customers nearer the central

office have faster connections and may see extremely high speeds in the future. ADSL

technology can provide maximum downstream (Internet to customer) speeds of up to 8 megabits

per second (Mbps) at a distance of about 6,000 feet (1,820 meters), and upstream speeds of up to

640 kilobits per second (Kbps). In practice, the best speeds widely offered today are 1.5 Mbps

downstream, with upstream speeds varying between 64 and 640 Kbps.

The reason for this is incompatibility of loading coils with ADSL signals, so a voice coil in the

loop between your telephone and the telephone company's central office will disqualify you from

receiving ADSL. Other factors that might disqualify you from receiving ADSL include:

Bridge taps - These are extensions, between you and the central office, that extend

service to other customers. While you wouldn't notice these bridge taps in normal phone

service, they may take the total length of the circuit beyond the distance limits of the

service provider.

Fiber-optic cables - ADSL signals can't pass through the conversion from analog to

digital and back to analog that occurs if a portion of your telephone circuit comes through

fiber-optic cables.

Distance - Even if you know where your central office is (don't be surprised if you don't -

- the telephone companies don't advertise their locations), looking at a map is no

indication of the distance a signal must travel between your house and the office.

The connection is faster for receiving data than it is for sending data over the Internet.

The service is not available everywhere.

The existing protocol supporting the Internet today - Internet Protocol Version 4 (IPv4) - provides

the world with only 4 billion IP addresses, inherently limiting the number of devices that can be

given a unique, globally routable address on the Internet. The emergence of IPv6, providing the

world with an exponentially larger number of available IP addresses, is essential to the continued

growth of the Internet and development of new applications leveraging mobile Internet

connectivity. Although the information technology (IT) community has come up with

workarounds for this shortage in the IPv4 environment, IPv6 is the true long-term solution to this

problem. Therefore, this type of transition should be done methodically and mindfully, with full

awareness of the benefits, challenges, and caveats surrounding the technical implementation of

IPv6.
