ADSL stands for Asymmetric Digital Subscriber Line.
Modem technology that transforms ordinary phone into
high-speed digital lines for ultra-fast internet access.
ADSL is a form of DSL, a data communications
technology that enables faster data transmission over
copper telephone lines ADSL , and supports voice, video
and data.
WHAT IS ADSL

4. 
Asymmetric - The data can flow faster in one
direction than the other. Data transmission has faster
downstream to the subscriber than upstream
Digital - No type of communication is transferred in
an analogy method. All data is purely digital, and
only at the end, modulated to be carried over the
line.
Subscriber Line - The data is carried over a single
twisted pair copper loop to the subscriber premises
WHAT DOES ADSL
MEAN

5. 
ADSL provides speeds up to 8 Mbps downstream
(i.e. downloads) and Mbps upstream (i.e. uploads).
up to 1
ADSL makes full use of the bandwidth of the
physical connection between your home and the
central office.
HOW FAST IS ADSL

6. 
Inside Your PC: Your computer's ADSL modem connects to a standard
analogy phone line.
Voice and Data: A DSL modem has a chip called a POTS splitter, which
divides the existing phone line into. two bands: one for voice and one for
data. Voice travels on the first 4kHz of frequency. The higher frequencies-
-up to 2MHz depending on line conditions and wire thickness--are used
for data.
Split Again: Another chip in the modem, called a channel separator,
divides the data channel into two parts: a larger one for downstream
Internet data and a smaller one for upstream Internet data .
ADSL MODEM

9. 
 Over the Wire: At the other end of the phone line--
located at the phone company's central office. This
modem also has a POTS splitter, which separates the
voice calls from the data.
 Telephone Calls: Voice calls are routed to the phone
company's public switched telephone network and
proceed on their way as usual.

ADSL LINE
CONNECTION

11. 
Simultaneous Internet and voice/fax
capabilities over a single telephone line.
Uninterrupted, high-speed Internet access
that's always on-line.
Cost-effective solution for residential
customers, telecommuters and small
businesses.
BENEFITS OF ADSL

12. 
ADSL is ideal for downloading because it
provides high downstream.
It allows continues internet service without
any interruption.
We can use voice calling even when there is
no internet service.
