Why ADSL so fast ?

Hi, new to SI, first post !

Modems work through the existing central office equipment,
in the "voice band", which is filtered down to a narrow
frequency range, so more calls can be trunked together -
this is what gives phone calls their 'tinny' sound.

ADSL requires new equipment at the central office end ( and at
the home end for full ADSL, but not for 'lite' ), so there is a
BIG expense to install the capability - however, it then frees
up the entire bandwidth of your wire for you to use.

Hope that helps. G.
