How does Northwestel High Speed Internet work?

Northwestel High Speed Internet uses a technology called asymmetric digital subscriber line (ADSL). ADSL transmits digital information at high bandwidths through existing telephone lines. Using an ADSL modem, copper twisted-pair telephone lines are converted into a high-speed digital pipe. ADSL is asymmetrical because most of the channel is dedicated to transmitting data downstream to the user. Only a small part is used to receive information from the user. The two streams don't interfere with each other because ADSL data is delivered at a high frequency. Phone and fax information is delivered at a lower frequency.
