A T-1 line is a high
speed digital connection
capable of transmitting data at a
rate of approximately 1.544
million
bits per second. A T-1 line is typically used
by small and medium sized
companies
with heavy network traffic. It is large
enough to send and receive
very large
text files, graphics, sounds, and
databases instantaneously,
and is the
fastest speed commonly used to
connect networks to the
Internet. Sometimes
referred to as a leased line, a
T-1 is basically too large
and too
expensive for individual home use.
A T-3 line is a higher speed connection
capable of transmitting data at
a rate of 45 million bps
(bits per
second). A T-3 line represents a bandwidth
equal to about 672 regular
voice grade
telephone lines, which is wide enough
to transmit full motion,
real-time
video, and very large databases over a busy
network. A T-3 line is
typically installed
as a major networking artery for large
corporations and universities
with
high volume network traffic. For example, the
backbones of the major
Internet
service providers are comprised of T-3 lines.
