Definition 1. -
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 2. -
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 Akaska T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet
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.

For many small to medium size businesses, higher productivity with relation to their broadband
and voice services is just around the corner. Thanks in part to the recent price reduction trend
in the industry, carriers have deemed it necessary to consolidate in order to offer more services
at a lower cost than their rivals. Overlapping networks have been consolidated into leaner, more
feature-rich versions of their previous selves, dramatically lowering the price small businesses
pay for the popular dynamic integrated T-carrier (T-1) lines that combine local voice and
high-speed Internet service into one connection.
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.
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.
"Commercial telecommunication providers were never on my Christmas card list"
commented Jake Chang, a small business owner in Denver, Colorado. "Dealing with them
meant erroneous bills, long wait times when trying to reach customer service, and
taxes I could never understand. Now that we migrated to a dynamic integrated
T1, my phone lines and high speed internet are bundled into one line with super
reliability. Not to mention the fact that XO Communications, a CLEC, treats me
like they actually want my business - not like I'm a pain in the you-know-what."
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.
"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.
Will this train of innovation, lower prices, and services that add value to SMB's continue
to roll down the tracks of progress? It's all up to our government - and which political
party controls the FCC. Without the deregulation act of 1996, we would have never known
just how much the CLECs were capable of.
