Why is Astutium ADSL better than a standard modem and telephoneline?

Modems were designed to allow computers to communicate over the standard PSTN - a system designed for voice communications only.

This limits the speed that computers can talk over the system as it is not sufficiently high quality - every digital signal has to be converted into an audible tone and then 'heard' by the remote computer.

This process is called modulation demodulation.

The fastest possible speed over a PSTN line is 56kbps or 128kbps on ISDN2.

ADSL upgrades your line to one designed for digital communication, capable of up to 24mbps.
