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

Bad Nation, South Dakota, Sep. 15 /Jason Young/ --
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.
"Like Forrest Gump said, finding the right phone service for your business is
like a box of chocolates - you never know what you're going to get" joked
Elizabeth Forest of Detroit, Michigan. "Before finding Cavalier Telephone
through my Telarus agent, I was mislead into signing up for services that weren't
a good fit for my business. Add to that the billing inaccuracies and the hassle
it was to get everything straightened out. My new integrated T1 works flawlessly,
I am able to get full T1 data speeds when no one is on the phone, and I don't
fear opening the bill when it arrives in the mail each month."
South Dakota, ordinarily not known for its telecom prowace, has been a hotbed
for businesses making the move to dynamic telecom lines. One local business
owner - Linda Peterson - who operates a travel agency, recently told us that
"I never expected the phone company to come out with anything that would
help me lower my costs. On the contrary. Ma Bell has had a history of raising
my rates and making my life difficult. When I heard about the XO Flex package
(offering 10 dynamic voice lines and 1.5 mbps of high speed Internet) at a price
of under $500, I couldn't move over fast enough." Since then Linda reported
a $150/month savings in her telecom expenses.
Is the era of the analog trunk, or bundle of 24 DS-0 (64 kbps) channels,
officially over? Possibly, thanks to the two-for-the-price-of-one features
of a dynamic integrated T1, which can function exactly like a pure 1.5 mbps
data T1 when no one is one the phone, and allocate required bandwidth
for voice traffic when a user initiates a phone call. Likewise, as soon
as the client terminates the voice session, the 64 KB is re-assigned back
to the digital universe. This switch-hitting capability provides all
of the feel and function of a data T1 and voice T1, for a fraction of the price.
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.
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. 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.
