ADSL Overview

The includes an ADSL modem for Internet access.

The ADSL technology offers high-speed fixed Internet connections over existent twisted-pair telephone lines. No new wiring is necessary and the telephone line is kept open for ordinary voice calls.


ADSL uses two pieces of equipment, one is your ADSL modem, and one is a modem, or a so-called DSL Access Multiplexer (DSLAM) located at your Internet Service Provider. The DSLAM is the equipment that really allows ADSL to happen. A DSLAM takes connections from many customers and aggregates them onto a single, high-capacity connection to the Internet.

The ADSL modem is compatible with DSLAMs from all major suppliers currently available on the market.
