Definition 1. -
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 Buckeye T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet
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. -
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 4. -
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.

Buckeye, New Mexico, Jun. 20 /Craig Docken/ --
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.
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.
To illustrate the types of decisions that small business owners are faced with
on a daily basis, we interviewed Glenda Probst, small business owner in Los
Angeles, California, about her recent move to a dynamic integrated T-1.
"I was in a quandary about how to go about expanding the number of voice
lines to my business. Before making the move to a dynamic integrated line,
I was using POTs lines. After the fifth line, my bill was above $300/month,
not including my $100/month DSL connection. Now, I have 12 pure digital
voice lines, 1.5 MB of broadband, and I pay under $400 for it. It was a major
upgrade in service with a reduction in total price. I only wish I'd learned
about this product sooner."
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.
"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."
Looking in the crystal ball of the future, it is clear that new an innovated services
being offered by the few super-CLECs remaining will drive innovation higher and prices
lower. New technology is being pressed to the forefront by lower prices that the mainstream
of small businesses everywhere can comfortably afford. Expect innovation to continue on its upward spiral as the CLECs continue to expand
their footprints as well as their customer bases. Barring any funny stuff from the FCC,
the CLECs will be here to stay. Sorry Ma Bell.
