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 Bryson 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. -
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. -
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.

Bryson, Texas, Sep. 09 /Jeff Johnson/ --
The digital universe, and the way people connect to it, is changing. Small businesses, in
particular, are discovering new high-speed Internet and telecom options that are now
squarely within their budgets. Through a myriad of mergers and acquisitions, telecommunication
providers have greatly enhanced their integrated T1 products with features that businesses
can't live without, all while dropping the price to about half of what they were just
two years ago.
When asked about his recent decision to replace his TDM channelized T1 with a
SIP-enabled dynamic T1, Robert Probst, small business owner in San Diego, explained
that "it was really an easy decision to make. My business was growing and I couldn't
afford the cost of more voice trunks. When I learned that it was possible to
have up to 16 voice lines, and a full data T1 of high speed Internet bandwidth,
all on the same line, for under $500 - I was sold. I ended up expanding the
telecom capability of my business, improving the quality of my Internet connection,
and saved money while doing it."
The old-school integrated T-1 was analog in nature, and came with 24 configurable
channels (called a trunk) which could be configured to carry either voice or data
traffic. The new "dynamic" trunks are all-digital and can change on-the-fly
to carry either data or voice traffic. This comes in handy when none of the voice
lines are in use - all channels can revert to carrying data traffic, giving the
end-use a full 1.5 MBPS of broadband. Each phone call requires only 64K of bandwidth,
so even a small handful of calls only slows down the data connection by a nominal
amount.
"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.
The early adapters of this new technology have realized a cost savings that helps
them be more competitive in the market space. By saving hundreds of dollars each
month, which equates to thousands of dollars per year, small businesses are able
to do more while spending less on their telecom bill. This savings allows for
hiring of additional staff, upgrading equipment, and other activities that make
the enterprise more productive and profitable. Many in the industry see the
lack of mass adoption of this new technology as just shear ignorance and/or
a lack of trust for telecom sales people.
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."
CLECs are continuing to find new and loyal customers in the small business space, but
for how long will this trend continue? Will the RBOCs ever be able to give them a fight
on a level playing field? Only the FCC knows that answer to that question - all we can
do is be thankful for the past 12 years of progress and hope we never return to the
pre-1996 era of Telecommunications. With the help of super-CLECs like XO Communications, PAETEC, Nuvox, One Communications,
Cavalier Telephone, and TelePacific, small business owners everywhere now have access
to non-Bell service that is on par or better than those being offered by the former
Bells. Integrated T1s that do more and cost less have transformed into a solid beach
head for the newcomers.
