- What is ADSL and how does it work?
ADSL stands for ‘Asymmetric Digital Subscriber Line’.
It is basically a broadband connection technology. The existing
copper wires installed for telephone systems are used for ADSL
technology. It is much faster than the modem connection. It
offers bandwidth needed for voice services so that the same
internet connection is used for
internet telephony and web surfing simultaneously.
- Does the distance from my local exchange affect my
Yes the distance from your local exchange matters. It is better
if the distance between the location where you want the ADSL
connection and local exchange is under 3 to 4 Km. If your business
is far away from local exchange, it may be possible that ADSL
service may not be available for you. One thing should be noted
that the apparent distance from your local ADSL exchange may
not be the actual measured distance that the cables travel.
Since the cables will not usually go directly between your office
and the exchange, even if the exchange is physically close.
- Can ADSL be used to provide connectivity to a network?
All of ADSL services come with one or more fixed IP addresses.
An IP address is the unique number that identifies a computer
or network on the internet. This will allow your computer or
network to be connected to the Internet with ADSL. ADSL connections
offer relatively high bandwidth compared with ISDN or modem
connection so ADSL
connection can be good enough for sharing across a small
- What is wires only ADSL?
Wires only ADSL is a 'self-install' ADSL product. ADSL is enabled
on a standard analogue telephone line and the telephone socket
is modified using an external, user-installable 'splitter' device
that provides separate data and phone connections into the standard
socket. The splitter plug works by separating the lower frequency
analogue voice signals and higher frequency ADSL data signals.
ADSL splitter devices are widely available in the market, require
no configuration and can be installed as easily as a two-way
- Is an ‘always on’ ADSL connection secure?
No computer connected to internet without firewall
is secure. It is strongly recommend that you should manage to
set up a firewall when using ADSL. All computer connected to
internet should be regularly checked for any harmful viruses,
and firewall should be up to date with the latest security fixes
and virus definitions.
- What is downstream?
Downstream refers to the transfer of data from the
requested information resource to your computer. ADSL connection
is asymmetric because it has download capacity more than capacity
to upload. It means that amount of information you can send
out in one second is considerably less than the amount of information
you can download to your computer. In any general case users
download more documents, web pages and e-mails than they send
out so having a higher downstream capacity is an efficient way
to use capacity.
