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. -
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 3. -
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 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 Marion T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

Marion, Oregon, Oct. 24 /Jeff Johnson/ --
During the 2000 Internet bubble meltdown, the telecom industry learned the hard way that
wild spending on network infrastructure was not the best approach to attracting new business
and investment. Over the past 7 years the industry, particularly the CLECs (Competitive
Local Exchange Carriers) have been focusing on building products that offer more bang
for the buck in order to compete with the Bells in their own backyards. One product that
has become the flagship offering to small to medium size businesses is the dynamic integrated
T1 line, which combines all the usefulness of 24 regular phone lines into a singe T-1
capable of delivering high-speed broadband on the same connection.
According to a recent study conducted by PK Communications Telecom Brokers Inc., the average
cost of a POTS (plain old telephone service) line serviced by the Bells (AT&T, Verizon,
and Qwest) have changed very little over the 10 year span from 1996, the year the
Clinton Administration signed into law the Telecommunications Act, to 2006. The real
change in the industry came in the T-carrier class of products, where customers can
get up to 1.5 Mbps of bandwidth and 24 digital phone lines all in one package. Some
CLECs like XO, TelePacific, Nuvox, One Communications, and even Covad are now offering
rates well below the $550/month level, making the change seem like a no-brainer to
thousands of customers.
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.
Ultimately it all comes down to basic economics. Whenever a technology can offer
more features for less money that what businesses are currently paying, it's just
a matter of time before the flood gates open up with companies wanting to adapt
the new standard. According to the Telecommunications Research Institute, headquartered
in Miami, Florida, the mass migration to dynamic integrated service offerings
is only being held back by a lack of education and/or the ability of carriers to
reach their target market. "Most people are leery of advertising and solicitations
by phone company salesman." comment Bill Bradley, analyst.
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.
To see how customers are reacting to this new product, we interviewed a series of
small business owners in Oregon who are currently using the service. One such
individual shared with us his enthusiasm for the enhanced capabilities dynamic
service offers. "When I was first contacted about the dynamic integrated T1,
I was deeply skeptical of what I was hearing. Over the course of my brief
dealings with telephone companies, all I got was less service with more cost.
Now I am happy to say that I am getting more for less, which makes for one
very happy customer."
Change does not happen quickly in an industry as so heavily regulated as Telecommunications.
Recent industry consolidation has provided huge alternatives to the incumbents, who
are now under pressure to keep up with new technologies while charging better prices
to retain and attract new customer bases. Hopefully the CLECs can continue to push the boundaries of innovation and economics.
The only thing that can keep them from the promise land is the gatekeeper of competition:
the Federal Communications Commission, and the huge Bells (AT&T and Verizon - that's you)
who make it a point to spend more money lobbying in Washington DC than Exxon Mobile.
