Initial setup and
connection |
Creates a new
connection every time you use the internet.
Your modem must
dial and make successful connection to an Internet Service Provider
(ISP). After you are done with your internet “session” you terminate
the “phone call”. |
Requires an
initial, one time syncing of signals between your computer’s special
DSL modem and the ISP’s network. Once your computer is successfully
connected to the ISP through this DSL connection, it remains
constantly connected unless the phone line, computer or modem is
physically unplugged or turned off.
Often referred to
as "always on" because it is not necessary to make a new setup call
each time you wish to access the Internet |
|
Use of Telephone
wiring |
“Ties up” the phone
line and disallows its usage for anything else, requiring the
dedicated use of a telephone line.
You cannot make or
receive a phone call while your computer and its modem are using the
internet. |
The same phone line
can service a phone call and an internet session simultaneously.

per second |
From 768,000
bits-per-second to
