How does ADSL work?
ADSL works on frequency
differentiation ? the frequency used by voice
is different from that used by data, which
is why you can use the phone and the Internet
at the same time.
|
# |
How fast is ADSL?
Very fast! ADSL provides
high-speed Internet access for extremely fast
downloads. ADSL also ensures data rates required
for different applications, such Internet access,
video and data transfer. In ADSL, the downstream
speed (from the ISP to the user) is higher
than the upstream speed, since when using the
Internet or other information services there
is always more data coming towards the user
than there is going up from the user. |
# |
What applications are supported
to run over DSL?
ADSL enables interactive
video and high-speed Internet access. The strength
of ADSL compared to other high-speed transmission
alternatives lies in the number of existing
telephone line. ADSL Internet Services are
a perfect solution for residences, small office/home
office ( SOHO), and telecommuters wanting higher
bandwidth access. ADSL provides a high- speed
connection to the Internet and has unlimited
opportunities for "information on demand" while
facilitating streaming applications that can
be used for business, education, and entertainment. |
# |
Can I still use my telephone
line if I have ADSL?
Yes! ADSL modems use
digital coding techniques to squeeze up to 99%
or more capacity out of a phone line without interfering
with your regular phone services. That means you
could be simultaneously talking on the phone or
sending a fax - while surfing the World Wide Web.
The two services (voice and data) operate independently
of each other even though they are using the same
telephone line. |

What are the key benefits
of ADSL for end users?
- Speed - ADSL provides
high-speed digital access.
- Always On - With ADSL,
a user is always connected. There is no
dial-up required and at any point of time
a user can jump onto the Internet. That
means no more logging on and off, no more
busy signals, and no more waiting for the
connection to happen-it's always there.
- Surf & Talk - You
can enjoy the benefit of using the phone
at the same time the your Internet connection
is on.
- Ease of use - ADSL
makes it possible to convert existing telephone
lines into high speed carriers, allowing
for ultra fast connection speeds and only
the installation of the ADSL modem is required.
Once the installation is complete, a user
simply clicks on the browser and the Internet
is connected.
- Reliable - ADSL utilizes
the existing telephone network, which is
highly reliable and is a proven means of
communication.
- Flexible - It does
not affect the normal telephone, so you
can make and receive telephone calls or
faxes while online.

What are typical speeds
offered?
For residential customers
we currently offer speeds ranging from 64 Kbps
onwards. |
# |
Can I use my ADSL connection
for other services in addition to browsing
the net?
Sure! ADSL enables
various types of services such as Video on Demand,
Interactive Online Games, Audio/ Video Streaming
and other high-speed services |
# |
What equipment do I need
for ADSL?
All you need is
a computer with a Universal Serial Bus (USB)
p ort. (Most new computers have this as a standard
feature). We will supply you with an ADSL modem
along with a setup CD, which is very convenient
to use. If you wish to use other DSL modems
on our network, make sure that the DSL modem
you buy is Alcatel chipset based. |
# |
Which operating systems
are supported to use DSL?
Compatible operating systems
are: Windows 98 SE/ ME/ 2000 and XP
MAC
Linux |
# |
How does ADSL compare
with competing technologies?
ADSL provides you with
an always on, high-speed, secure connection to
the Internet. With ADSL you do not share your bandwidth
from the ISP with other users. In contrast, competing
technologies share bandwidth on the same cable:
your performance with these other technologies
can vary greatly, depending on the number of users
connected. |
# |
How secure is data
transmitted via ADSL?
In
this age of
electronic
commerce, security
is becoming
a prominent
concern amongst
Internet users.
With ADSL technology,
using your computer is extremely secure. Your
ADSL service is dedicated to your telephone line
and none of your private information will pass
by any other user's PC on the network, like other
high- speed service offerings. With more and
more transactions involving credit cards on the
Internet, ADSL offers security for both the customer
and the business user. However, for additional
security, using updated Anti-Virus and firewall
applications will protect you more.

# |
Will everyone be
able to take advantage
of ADSL?
There
are a number
of factors that will affect whether or not an
individual can have ADSL:
- Your local exchange needs to have been
provisioned for ADSL.
- You should be located a certain distance
from the local exchange because ADSL is
distance dependent.
- This distance is typically around 4.5km
to 5.0 KM (the copper line from exchange
to your location).
- After the service has been ordered, our
technicians will carry out a survey on
the PSTN line, to ensure that ADSL can
actually be delivered over your phone line.
