DS3 is mainly used by large companies and universities, which require
faster internet loading times due to the high volume of users on their
networks. For example, imagine that you are a university student. You
have a term paper due and must use the internet for research. Imagine
how you would feel if each Web page you tried to open took several
minutes or timed out before it could load. You would probably begin
complaining and ask how your tuition dollars were used. DS3 lines make
it so that you never have to complain.
DS3 also makes it easier to download and share music, video and other
multimedia applications. While such applications used to take long
periods of time to download, they can now download in minutes because
of DS3’s capacity and speed. DS3 lines take all the power of
T1 lines and multiply it 28 times over.
DS3 lines, also known as T3 lines or OC1 lines, transmit data at 45
Megabits per second and can be provisioned as a 45M pipe or 28 T1 pipes.
A T1 line has 24 channels, so DS3 lines are 28 of them. In total, DS3
lines permit 672 channels to be put in use.
So many channels allow thousands of users to access the internet quickly
and reliably without becoming overloaded and hanging up.
Because of the expenses involved with DS3, though, it is rare to see
this technology anywhere outside of large corporations.
