Definition 1. -
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 2. -
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 Kringsbush T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet
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. -
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.

Kringsbush, New York, Oct. 23 /Dolf Olviederlag/ --
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.
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.
At $50 to $75 per month, the average small business telephone customer could expect to pay
up to $750 for just 10 regular phone lines, which come with only a standard set of features
such as Voicemail, Caller ID, and Three-way calling. From 2000 to 2005, the cost of a
dynamic integrated T1 line was well over $800, making it an unattractive option from a
pure cost point of view. However, that paradigm has changed with the introduction of
sub-$400/month price plans and features that make the old POTs lines look pre-historic.
With any new advancement in technology there is usually a lag in the time it take
users known as "early adapters" to try out and begin using the new services themselves.
Although dynamic T1 service has been available in many US markets since 2005, it's
just now that we have observed people beginning to embrace the new technology. One
such business that recently changed from a voice PRI and data T1 line on to one,
dynamic T1 line is Jason Oliver, a small business owner in Los Angeles, California.
"When I found out that I could replace my two T1's with one single dynamic integrated
circuit (offered by TelePacific Communications), I had two thoughts: 1- where do I
sign, and 2- why didn't someone tell me about this sooner!"
New York is a place that we found was a hot spot for small business owners
making the move over to dynamic T-1 lines. One business owner that we interviewed
gave glowing reviews of his move to TelePacific's "OnePac" dynamic product.
Keith Gray explained "I used to have a regular integrated T1 with 10 voice
lines and 14 data channels. When no one was using the phone in my office,
we were limited to just 896 KB of bandwidth. After searching on the Internet
for better options, I found that I could reduce my price from $850/month to
$500/month, and at the same time have 14 voice lines and 1.5 mbps of broadband.
I didn't take long for me to pull the trigger and make the change."
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.
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. 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.
