How does an ADSL modem work?
ADSL Modems offer a very high speed connection to the Internet, up to 24Megabits per second (over 428 times the speed of a 56k dial up modem). Technically speaking, though, an ADSL modem is not a modem at all, but a broadband network tree spanning bridge. Instead of using the narrow bandwidth required for a voice call (narrowband), it uses a much wider channel on the phone cabling to send and receive data (broadband).
