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

Greeley, Nebraska, Nov. 10 /Don Romburgh/ --
Is there a resurgence in the popularity of telecommunications providers that compares with
the late 1990's? The answer may surprise you. Since the crash of the Internet bubble,
struggling telecoms have seen Darwin in action as many companies were forced with the
choice of bankruptcy or forced consolidation. However, some companies chose the road less
traveled: innovation. By offering customers more for less, many small to medium size
business customers are finding that they can upgrade to integrated T1 service for the
same cost of five regular phone lines.
"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.
Nebraska 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."
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.
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.
"I am very satisfied with my new XO dynamic T1" added Mike McLoude, a small business
owner in Santa Monica, California. "The flexible nature of the system allows me to
conduct business with the same efficiency as many of my bigger competitors, for less
than what they pay." Mr. McLoude is not alone - many Californians are seeing the
technology light and taking the leap of faith away from traditional TDM.
The recent progress made by CLECs leaves us thinking in hypotheticals. "What if the
Clinton administration wouldn't have passed the Telecommunications Act of 1996, requiring
RBOCs to lease their lines at reduces rates to the CLECs?" "Will the FCC continue to
enforce this law, or will it be overturned by the powerful AT&T and Verizon lobbyists?"
It is impossible to know either way, but for the time being we can just be grateful
that the industry has evolved to the point were small businesses can actually benefit
from telecommunications at an affordable rate. 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.
