Broadband ADSL Overview

Broadband ADSL is a technology for transmitting digital information at a high bandwidth on existing phone lines to homes and businesses.

Broadband ADSL is different to your ordinary internet connection in many ways as:

  • It provides a permanent connection to the internet.
  • It is asymmetric in that it uses most of the channel to transmit downstream to the user and only a small part to receive information from the user.
  • It simultaneously accommodates analog (voice) information on the same line. This is done by installing a filter on your existing phone line, which blocks all signals above a certain frequency. Since all voice conversations take place below 4 KHz, the low-pass filters are built to block everything above 4 KHz, preventing the data signals from interfering with standard telephone calls.

Westnet offers both Broadband1 and Broadband2+ services. For more information, visit the Broadband Internet page in our website.
