How does ADSL work?
Asymmetrical Digital Subscriber Line provides always on Internet access over your existing phone line. Using a special ADSL modem and line filters, the frequency bands that are available on the copper phone line are expanded to enable higher speeds.

ADSL uses frequency bands between 0 and 4 Khz for your telephone service and 20 Khz to 2.2 Mhz for your ADSL service - this is how you are able to use both ADSL and your telephone at the same time.

ADSL uses Asymmetric transmission which means that it is faster transferring information from the Internet to your computer than it is transferring information from your customer to the Internet. 56K modems also use the same Asymmetric transmission method.

There are some limitations however to ADSL technology, the first one being you must be in an ADSL enabled exchange area. Other limitations are:

   •   Being within 7 to 9km of your local exchange

   •   Not on a "Pair Gain" system

   •   And not on a RIM

Once you submit your application to Highway, we are able to see if you are in a "Pair Gains System" or other technology blockers. If your line can not be activated, we will notify you and refund any monies paid.
