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

During the 2000 Internet bubble meltdown, the telecom industry learned the hard way that
wild spending on network infrastructure was not the best approach to attracting new business
and investment. Over the past 7 years the industry, particularly the CLECs (Competitive
Local Exchange Carriers) have been focusing on building products that offer more bang
for the buck in order to compete with the Bells in their own backyards. One product that
has become the flagship offering to small to medium size businesses is the dynamic integrated
T1 line, which combines all the usefulness of 24 regular phone lines into a singe T-1
capable of delivering high-speed broadband on the same connection.
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.
Min Lieu owns a small insurance agency in Virginia. Five years ago he signed up with
XO Communications for a TDM-based integrated T1 line for $870/month, which did not
include local or long distance calling. Recently, he was offered XO's version of
a dynamic circuit called "XO Flex" for half of the price he was already paying.
"I would have been a fool not to take the deal" stated Mr. Lieu. "I'm able to
add headcount with additional voice lines, without any increase in expense or
degradation in high-speed Internet performance."
"The average cost of a business phone line from the Local Bell Operating Company (ILEC) has
remained constant for the past ten years" noted Edwin Jones, a senior market analyst and
telecom industry expert. "At the same time the prices of T-1 lines have declined from near
$1000 per month to a staggering $350. Keeping in mind that a T1 connection is the equivalent
of 24 regular phone lines all bundled into one, it comes as no surprise that demand for these
services in on the rise."
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.
The adoption of any new telecommunications platform is never instantaneous. Many
technologies, like VoIP for example, have been in the works for years without
gaining much traction. Enterprises see communications as their life blood. Even
though many are becoming aware of newer, cheaper mediums by which they can conduct
business, the risk still outweighs the rewards in their minds. Couple the
'if it isn't broken, why fix it?' mind set with the telecom meltdown of the early
2000's and it isn't surprising that widespread adoption of new telecom services
has lagged. However, the new technologies of IP-based voice systems are finally
starting to gain an audience, and the chorus of satisfied customers continues to
grow. As this momentum pushes forward, so does general acceptance of it viability.
But how much longer will we continue to see improved technology, services, and prices?
It's all in the hands of the Federal Communications Commission, as they have the power
to sqwash the CLECs by proxy. No wonder AT&T and Verizon are the two biggest lobbying
powers in Washington. It makes you wonder what kind of services they would be able to
offer had they plowed that money into R&D instead of politics. Looking in the crystal ball of the future, it is clear that new an innovated services
being offered by the few super-CLECs remaining will drive innovation higher and prices
lower. New technology is being pressed to the forefront by lower prices that the mainstream
of small businesses everywhere can comfortably afford.
