BTS MAINTENANCE DEPARTMENT-

The owners of BTS industrial maintenance must know troubleshoot, repair, and upgrade equipments.

There is a field technician who works on production lines or single machines. His skills are based on a

good knowledge of automated systems and mechanical and electrical equipment, as well as controlmethods as well as preventive maintenance and corrective.

It can make a diagnosis of failure to review a series of interventions and analyzed to determine the

specifications of new facilities. Once these installations made, it can receive and supervise their

implementation.

BTS (Base Transceiver Station)-

A base transceiver station (BTS) is a piece of equipment that facilitateswireless communication

betweenuser equipment (UE) and a network. UEs are devices likemobile

phones (handsets),WLLphones,computers withwireless internet connectivity,WiFi andWi-

Max devices and others. The network can be that of any of the wireless communication technologies

likeGSM,CDMA,Wireless local loop,WAN,WiFi ,Wi-Max,etc.

There can be two types of BTS-indoor and outdoor .The specifications for indoor and outdoor are given

above. The major difference between both is that the indoor BTS requires AC as the components used in

it generates heat which is not suitable for Indian weather and thus may cause the circumstances of fire.

Other differences are that outdoor BTS does not require any shelter while indoor requires shelter.Also,

indoor BTS are more sensitive than outdoor BTS.

2G and 3G BTS-

A 2G BTS has 1PCM while a 3 G BTS has 3 PCM while the number of alarms in 2G BTS is 16 and in

3G BTS is 30.We prefer 3G BTS over 2G because there is more data security in 3G and efficiency is also

better in 3G.

The 3G BTS is nowadays converting to IP based network, therefore it is becoming a RNC which will

handle with higher data rates giving speed up to 14Mbps.

WiMAX-

Wi-MAX is an acronym that stands for World-wide Interoperability for Microwave Access. It is an ideal

method for ISP to deliver high speed broadband to locations where wired connections would be difficult

or costly. Wi-MAX delivers a point-to-multipoint architecture. It doesn't require a direct line of sight

between the source and endpoint and it has a service range of 50 Kms. It provides a shared data rate of up

to 70 Mbps, which is enough to service up to a thousand homes with high-speed access.

NIB (NATIONAL INTERNET BACKBONE) DEPARTMENT-

BSNL is commissioninga multi-gigabit, multi-protocol,IP infrastructure through National Internet

Backbone-II (NIB-II), that will provide services through the same backbone and broadband accessnetwork.





Various fundamentals of NIB department are categorised below-

Broadband-

BSNL Broadband is an Internet access service from state-owned Bharat Sanchar Nigam Limited (BSNL)

available inIndia since 14 January 2005. Until 30 September 2007 it was known as Data One.

Broadband is often called high-speed Internet, because it usually has a high rate of data transmission. In

general, any connection to the customer of 256 kbit/s or more is considered broadband.

1.Landline Broadband-Landline broadband uses a landline as its medium of communication. If you do not

have a landline, you cannot get a fixed-line broadband connection. If you cannot get a landline, you may

have to opt for mobile broadband.

2.Mobile Broadband (3G)-Mobile broadband is the marketing term for wireless Internet access delivered

through mobile phone towers to computers,mobile phones and other digital devices usingportable

modems.The modem may be built into laptop computers, tablets, mobile phones, and other devices,

added to some devices usingPC cards,USB modems,andUSB sticks ordongles,or separatewireless

modems can be used

3.WIMAX Broadband-This technology provides fixed as well as fully mobile high speed broadband

connectivity along with roaming feature. It provides users a thrilling Internet browsing experience. BSNL

offers large variety of Customer Premises Equipments ( CPE) including Outdoor, Indoor and USB

dongles.

DSLAM-

DSLAM (Digital Subscriber Line Access Multiplexer) is an integrated hardware and software system thatallows the user to access broadband services as well as originate and terminate telephone calls over the

same single pair of copper wires.

DSLAMs have been categorized into seven types based on the number of ports (960, 480, 240, 120, 64,

32, 16) provided and planned for deployment based on the expected demand.

ADSL

ADSL stands for Asymmetric Digital Subscriber Line. It is a technology that allows copper telephone

pairs to be used to provide a broadband connection. It provides always-on Internet connection that is

automatically established once the PC and ADSL modem are switched on.

The Plesiochronous Digital Hierarchy (PDH)

In a PDH network you have different levels of Multiplexers.Figure01 shows three levels of multiplexing:-

2Mbit/s to 8Mbit/s

8Mbit/s to 34Mbit/s

34Mbit/s to 140Mbit/s

So to carry a 2Mbit/s data stream across the 140Mbit/s trunk requires it to be multiplexed up

through the higher order multiplexers into the 140Mbit/s trunk and then to be multiplexed down

through the lower order multiplexers. Because Plesiochronous is not quite Synchronous

each of the multiplexers need a little bit of overhead on their high speed trunks to cater for the slight

differences in data rates of the streams on the low speed ports. Some of the data from low speed ports

(that are running too fast) can be carried in the trunk overhead, and this can happen at all multiplexing

levels. This is known as Justification or Bit Stuffing.

PDH Multiplexing Hierarchy

Figure 2 shows that there are two totally different hierarchies, one for the US and Japan and another for

the rest

of the world.

The other thing to notice is that the different multiplexing levels are not multiples of each other.

For example CEPT2 supports 120 Calls but I requires more than 4 times the bandwidth of

8/11/2019 Bsnl 20 Pages

11/16

CEPT1 to achieve this. This is because PDH is not exactly synchronous

and each multiplexing level requires extra bandwidth to perform Bit Stuffing.

So the Plesiochronous Hierarchy requires Bit Stuffing, at all levels, to cater for the differences

in clocks. This makes it particularly difficult to locate a particular 2Mbit/s stream in the 140Mbit/s trunk

unless you fully de-multiplex the 140Mbit/s stream all the way down to 2Mbit/s.

Synchronous Digital Hierarchy Concept:

Introduction

It is an international standard networking principle and a multiplexing method. The name of hierarchy has

been taken from the multiplexing method which is synchronous by nature. The evolution of this system

will assist in improving the economy of operability and reliability of a digital network.

Merits of SDH

(i) Simplified multiplexing/demultiplexing techniques.

(ii) Direct access to lower speed tributaries, without need to multiplex/demultiplex the entire high speed

signal.

(iii) Enhanced operations, Administration, Maintenance and provisioning capabilities.

(iv) Easy growth to higher bit rates in step with evolution of transmission technology.

(v) Capable of transporting existing PDH signals.

(vi) Capable of transporting future broadband (ATM) channel bit rates.

(vii) Capable of operating in a multi-vendor and multi-operator environment.

NIB DEPARTMENT

BSNL is commissioninga multi-gigabit, multi-protocol,IP infrastructure through National Internet

Backbone-II (NIB-II), that will provide services through the same backbone and broadband access

network.





All the basic fundamentals related to this department are explained below.

Basic Terminologies related to NIB:

1. Network

In one network more than one computer connected with each other through centralized device. They can

share files and resources with each other.

a. LAN: LAN stands for Local Area Network. The scope of the LAN is within one building, one school

or within one lab. In LAN (Hub), media access method is used CSMA/CD in which each computer sense

the carrier before sending the data over the n/w.

b. WAN: WAN stands for Wide Area Network, in which two local area networks are connected through

public n/w. it may be through telecommunication infrastructure or dedicated lines. For e.g: - ISDN lines,

Leased lines etc.

2. Devices:

a. HUB: Hub is centralized device, which is used to connect segments of a LAN. The media access

method is used CSMA/CD (Carrier Sense Multiple Access/Collision Detection). It has no special kind of

memory. It simply receives the frame (data) and forwards it to all its nodes except the receiving node.

There are two types of Hub: -

(i) Active Hub:In Active hub, it receives the frame regenerate and then forward to all its nodes.

(ii) Passive Hub:In Passive hub, it simply receives the frame and forward to all its connected nodes.

b. SWITCH: Switch is also used to connect multiple workstations. Switch is more intelligent than hub. It

has special kind of memory called mac address/filter/lookup table. The media access method is usedCSMA/CA (Carrier Sense Multiple Access/ Collision Avoidance). Switches provide more efficiency,

more speed and security.

There are two types of switches: -

(i) Manageable switches

(ii) Non-manageable switches

c. BRIDGE:

Bridge is a hardware device, which is used to provide LAN segmentation means it is used for break the

collision domain. It has same functionality as performed by switch.

d. ROUTER:

Router is hardware device, which is used to communicate two different networks. Router performs

routing and path determination. It does not perform broadcast information.

There are two types of routers: -

(i) Hardware Routers

(ii) Software Routers

6.2 Internet Services:

Internet access is the means by which individual terminals, computers, mobile devices, and local area

networks are connected to the globalInternet.Internet access is usually sold byInternet Service Providers

(ISPs) that use many different technologies offering a wide range ofdata rates to the end user. Consumer

use first became popular throughdial-up connections in the 1980s and 1990s. By the first decade of the

21st century,many consumers had switched away from dial-up to dedicated connections, most Internet

access products were being marketed using the term "broadband", and broadband penetration was being

treated as a keyeconomic indicator.

CONCLUSION

It was a great experience to be there in the TRANSMISSION, BTS MAINTANENCE and NIB

department of the BSNL office for attending the internship. Like every good thing, it had to come to an

end and so it did. I have the great memories of the time spent here.

At the end of my six month industrial training I learned about:-

Transmission department, its working and about the equipments used in Transmission.

Broadband department, its working and about the equipments used in NIB.

Base Transceiver Station, its working and about the equipments used in BTS.

I got an experience of working with professionals.

During the training period, I certainly learnt a lot about the technical and practical details about the

various aspects of the communication field. I certainly got a very good industrial exposure working here

in BSNL.

The things are numerous, while words are only few. To conclude, I would rather say that after my full try,

I could pick up only a mouthful of knowledge out of the sea. The time was really less while there was a

lot to learn.

I hope I would have another chance to attend a similar programme and learn more in it.
