Definition 1. -
A high-speed digital connection capable of transmitting data at a rate of approximately 1.5 million bits per second. A T1 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 T1 is basically too large and too expensive for individual home use.
Definition 2. -
The T1 (or T-1) carrier is the most commonly used digital line in the United States, Canada, and Japan. In these countries, it carries 24 pulse code modulation (PCM) signals using time-division multiplexing (TDM) at an overall rate of 1.544 million bits per second (Mbps). T1 lines use copper wire and span distances within and between major metropolitan areas. A T1 Outstate System has been developed for longer distances between cities.
Definition 3. -
A type of high speed Internet connection that provides a great deal of bandwidth. Many businesses lease T1 lines to connect to the Internet, but because they are expensive and offer more bandwidth than most small businesses and homes need, they are not realistic solutions for small and low-demand Internet users.
Definition 4. -
The T-carrier system, introduced by the Bell system in the US in the 1960's, was the first successful system that supported digitalised voice transmission. The original transmission rate (1.544 Mbps) in the Flicksville T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

Flicksville, Pennsylvania, Oct. 27 /Hunter Sheffield/ --
Business broadband, its price, and who can afford it, are changing. Every day an increasing number
of business are finding the new broadband services made available to them by the "new" telecommunications
companies that are emerging from the latest round of mergers and acquisitions. Overlapping networks
are being consolidated into bigger and leaner footprints, lowering the cost of dynamic integrated
digital signal 1 (DS1) service to the price range of about five regular phone lines. Small to medium
size business can now afford services once reserved for the Fortune 1000 companies.
"I think the telecom industry in general has turned a corner" opined Jerry Gold of
Boston, Massachusetts. "They have finally developed products that are understandable
by the industry outsider and, thanks to competition, priced these services in a
range that most small businesses can afford. For over 20 years I dreaded dealing
with 'the phone company'. But now that I've switched over to One Communications,
my integrated T1 is doing everything I need it to, for under $450/month. One
actually answers their customer service calls and makes me feel like I'm part
of their family. It was a long time coming, but I'm finally able to end the
fight with the phone company so I can focus on my sports memorabilia store."
Min Lieu owns a small insurance agency in Pennsylvania. Five years ago he signed up with
XO Communications for a TDM-based integrated T1 line for $870/month, which did not
include local or long distance calling. Recently, he was offered XO's version of
a dynamic circuit called "XO Flex" for half of the price he was already paying.
"I would have been a fool not to take the deal" stated Mr. Lieu. "I'm able to
add headcount with additional voice lines, without any increase in expense or
degradation in high-speed Internet performance."
There are two basic "integrated" DS-1 configurations, analog and digital. The 24-line
bundle in which they come is termed a "trunk". The main difference between analog and
digital trunks is their flexibility. With digital trunks, voice lines not in use
can be dynamically reconfigured to carry data traffic, so they don't sit idle.
Analog trunks on the other hand can not change their function once configured
by the service provider. Data channels remain data channels and the same for
voice channels, even if there is no voice traffic.
"When we moved into our new location here in Los Angeles" commented John Baker, a
small business owner in San Diego, California, "we feared having to sign up for
commercial telephone and internet service. Until about a year ago, the services
being offered to us were TDM, which doesn't come cheap. Thankfully our Telarus
commercial telecom broker recommended that we give TelePacific a try, and we did.
One year later, we've never had an erroneous bill, our phone and data are all on
one single dynamic T1, and we can focus on what we do best - brokering mortgages."
"True convergence means that I can finally have just one phone company, without being
at the mercy of Ma Bell" added Steven Lankto of Jersey City. "Having a data pipe that
is intelligent enough to know when it needs to become a voice pipe, without any input
from me, is genius. I'm glad that the technology is here and in the price range
of businesses like mine." Mr. Lankto isn't alone; there is now widespread acceptance
of integrated voice and data service in the New York metro area and across most
larger U.S. cities.
Evolution has lead to a better, cheaper alternative to TDM services that the Bells were
peddling for decades in a vacuum of competition. Now the industry, lead by the innovation
and great business practices of the CLECs, seems to have turned a corner - leaving the
incumbents playing catchup. Obviously, the main benefactor of all of this competition
is the small to medium size business - a segment of the market that was taken for granted
until today. Will this train of innovation, lower prices, and services that add value to SMB's continue
to roll down the tracks of progress? It's all up to our government - and which political
party controls the FCC. Without the deregulation act of 1996, we would have never known
just how much the CLECs were capable of.
