Evolution of Broad-Band

The confluence of 2 forces – Globalization of business

and the networking of information technology - has

created the internet economy

The new economy is defining how people do business,

communicate, shop, have fun, learn and live on a global

basis–CONNECTING ANYONE, ANYWHERE, ANYTIME


basis–CONNECTING ANYONE, ANYWHERE, ANYTIME

As the internet market continues to explode, the demand

for greater bandwidth and faster connection speeds has

led to the need to provide broadband access to the end

users.

One of the latest trends in enhancing

communication systems involves broadband

technology

Broadband refers to greater bandwidth-or

transmission capacity of a medium

Evolution of Broad-Band


transmission capacity of a medium

Broadband technology will allow for high-speed

transmission of voice, video, and data over

networks like the Internet

TRAI DEFINITION OF BROADBAND

•An ‘always-on’ data connection supportinginteractive services including

– Internet access and has the capability of the

minimum download speed of 256 kilo bits per

second (kbps) to an individual subscriber from the

Point Of Presence (POP) of the service provider.


Point Of Presence (POP) of the service provider.

– The interactive services will exclude any services

for which a separate licence is specifically

required, for example, real-time voice

transmission, except to the extent that it is

presently permitted under ISP licence with Internet

Telephony.”

ADVANTAGES OF BROADBAND

Always on (Not a Shared Media)

Fast (speed ranging from 256 kbps to 2 Mbps)

No disconnection

No additional access charge


Telephone and Data simultaneously

Fat Pipe has to be continuously supplemented

with value added applications to enjoy the

advantage.

WIRED BROADBAND TECHNOLOGIES

Digital Subscriber Lines (DSL)

Cable Modem (CM)

Fiber Technology (FITL)

Power line Broadband(BPL)


DIGITAL SUBSCRIBER LINE (DSL)

• Digital Subscriber line (DSL) is a wire line

transmission technology that brings data and

information faster over copper telephone lines

already installed in homes and business.


• DSL exploits "extra capacity" to carry information

on the wire without disturbing the line's ability to

carry conversations.

xDSL FAMILY TREE

xDSL

Symmetric DSL

Provide identical data rates upstream & downstream

Asymmetric DSL

Provide relatively lower rates upstream but higher

rates downstream


rates downstream

Types of xDSL :

� HDSL - High data rate Digital Sub: Line

� SDSL - Symmetrical Digital Sub: Line

� ADSL - Asymmetric Digital Sub: Line

� IDSL - ISDN Digital Sub: Line

� VDSL - Very-high-data-rate Digital Sub: Line

SDSL

Symmetrical Digital Subscriber Line

Used typically for business applications


such as video conferencing.

The data rate in both directions is equal.

ADSL

Asymmetrical Digital Subscriber Line

Used primarily by residential users who receive a

lot of data but do not send much such as Internet

surfers.


ADSL provides faster speed in a downstream

direction (from the telephone central office to the

customer’s premises) than upstream (from

customer’s premise to the telephone central

office).

HDSL

High Data Rate Digital Subscriber Line

Provides fixed symmetrical high-speed access

at T1 rate (1.5 Mbps).

Designed for business purposes


Designed for business purposes

VDSL

Very High Data Rate Digital Subscriber Line

Provides both symmetrical and asymmetrical

access with very high bit rate over the copper


access with very high bit rate over the copper

line.

IDSL

ISDN Digital Subscriber Line

Provides symmetrical connection with

Integrated Services Digital Network (ISDN).

Designed to extend DSL to locations with a

long distance to a telephone central office.

DSLAM

Digital Subscriber Line Access Multiplexer.

Equipment located at a phone company’s central

office (CO).

Links many customer DSL connections over

existing copper telephone lines to a single high-


existing copper telephone lines to a single high-

speed ATM line.

DSLAM

Intermixes voice frequency signals and high-speed

DSL data traffic into a customer’s DSL line.

Separates incoming phone and data signals and

directs them onto the appropriate carrier’s network.

Voice calls are sent to the PSTN, and data are


Voice calls are sent to the PSTN, and data are

sent to the DSLAM.

DSLAM is connected to Internet Backbone for

access to World Wide Web and other applications.

BSNL’S BROADBAND ACCESS TECHNOLOGY

BSNL has a world class, multi-gigabit, multi-

protocol, convergent IP infrastructure – The NIB.

BSNL Broadband service provides convergent

services through this backbone network.


Asymmetric Digital Subscriber Line (ADSL)

Technology is used for giving the Broadband

connection where greater download is required in

comparison to upload.

EFFECT OF COPPER PAIR QUALITY

Data speed capability depends on the

thickness of wire used in cable network.

Higher the gauge, higher the data carrying

speed.

Data speed deteriorates if copper loop quality


Data speed deteriorates if copper loop quality

is bad i.e. more joints, loose joints, low

insulation etc.

BSNL Broadband Vs Cable Modem Service

Cable Modem (internet service given by Cable TV

operators) offers shared bandwidth.

Speed is asymmetric and will vary depending on the

number of people on the network.

With high-speed Internet access that uses DSL

service, one gets a dedicated connection to the

The performance of DSL based service depends on

the distance between end user and phone company

central office.

SOME CONCEPTS

Single User (SU):

Only one PC can be connected to BSNL Broadband connection.

Multi User (MU):

Customer is allowed to share one BSNL broadband connection among

multiple PCs

Static IP address:


For many services such as video conferencing, VPN etc. a fixed IP known as

Static IP is required.

Dynamic IP:

For normal Internet browsing, the customer does not require static IP. BSNL

allocates temporary IP address to the customer when a session is initiated.

SPEED CHECK

Customer is assured of promised speed.

Customer can check speed for their connection at

link http://www.dataone.in/.

The check is performed by measuring the speed of

a file transfer.


a file transfer.

The file transfer is counted towards download limit.

DATA USAGE

It is the aggregate of data uploaded and

downloaded through broadband connection.

The Data Usage is accounted in GB (Giga Bytes).


A customer subscribed for Games on Broadband,

the data usage is normally not charged separately

responsible for reassembling the packets into a video

stream and then decoding the contents.

IPTV is typically bundled with other services like Video

on Demand (VOD), Voice Over IP (VOIP) or digital


on Demand (VOD), Voice Over IP (VOIP) or digital

Phone, and Web access.

IPTV viewers will have full control over functionality

such as rewind, fast-forward, pause, and so on.

SET TOP BOX

It is a device at the customer premises through

which a subscriber accesses the various IPTV

services.

The Set Top Box typically includes an embedded


The Set Top Box typically includes an embedded

operating system, decoders and decryption

subsystems and client infrastructure components

such as Web Browser, and protocols for

delivering the TV services.

SET TOP BOX

The set-top box is a smart solid-state device that

acts as the gateway to a host of services offered

on the BSNL Multiplay network.

Set-top box interfaces with the television using the

3-RCA or the S-Video ports, and to broadband

ADSL modem via the Ethernet port.

to use the Internet as the transmission medium for

telephone calls.


telephone calls.

3. VoIP works through sending voice information in digital

form in packets,

4. VoIP also is referred to as Internet telephony, IP

telephony, or Voice over the Internet (VOI)
