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.
