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 Barre Junction T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

Barre Junction, Vermont, May. 27 /Brendan Luna/ --
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.
Integrated T1s comes in two basic configurations: digital and analog trunks, with a trunk
being a 24-line (or channel) bundle. The newer, digital trunks, however, are able to
run both voice and data over the same channels. By assigning priority to the voice
traffic whenever it is present, a dynamic integrated trunk can provide the end-user
with a full 1.5 MBPS of data throughput if no phone calls are in progress. As more
voice lines are required, less data lines are available. Analog trunks are all
pre-assigned to either voice or data traffic, and do not reconfigure in the event
there is no voice traffic.
"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.
"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."
The two basic Integrated T1 line configurations, as they exist in today's
market, are analog and digital. Commonly referred to as "trunks", these 24-channel
bundles transmit TDM signals directly to the service provider's network via a
local loop. Unlike analog trunks, whose configuration can not change once the
channels have been allocated, digital "dynamic" lines can change reconfigure
themselves from data, to voice, and back again. This ability to reclaim voice
channels for data broadband access when not in use gives the user the performance
of two T1's in one.
"What we're seeing here is the Bells holding their prices steady and milking their high
margins on POTS (plain old telephone service) lines for as long as possible. With the
lower prices being offered by CLECs (Competitive Local Exchange Carriers) on dynamic
integrated T-carrier services, the Bells are scrambling to keep pace before enterprises
realize they can actually save money by upgrading to bigger and more reliable circuits."
commented Don Rosebush, industry expert.
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. The golden age of telecommunications may be upon us, based upon our research and
recent uptick in customer satisfaction. Although the industry has years of
bad blood to overcome, recent innovations such as the dynamically configuring
T1 line are proof that progress is indeed being made.
