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

The way business connect to the digital universe is changing. More and more enterprises are
discovering the new broadband options made available to them through a series of cost cutting
measures by telecommunication providers. With the recent rush to consolidate, more and more
features are being crammed into the current service offerings, which continue to fall in price
bringing products like integrated T1 service into the price range of the vast majority of
small to medium-size businesses.
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.
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.
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."
Mississippi, 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.
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. Evolution has lead to a better, cheaper alternative to TDM services that the Bells were
peddling for decades in a vacuum of competition. Now the industry, lead by the innovation
and great business practices of the CLECs, seems to have turned a corner - leaving the
incumbents playing catchup. Obviously, the main benefactor of all of this competition
is the small to medium size business - a segment of the market that was taken for granted
until today.
