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

Cranston, Iowa, Sep. 26 /Jeff Johnson/ --
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.
"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.
According to a recent study conducted by PK Communications Telecom Brokers Inc., the average
cost of a POTS (plain old telephone service) line serviced by the Bells (AT&T, Verizon,
and Qwest) have changed very little over the 10 year span from 1996, the year the
Clinton Administration signed into law the Telecommunications Act, to 2006. The real
change in the industry came in the T-carrier class of products, where customers can
get up to 1.5 Mbps of bandwidth and 24 digital phone lines all in one package. Some
CLECs like XO, TelePacific, Nuvox, One Communications, and even Covad are now offering
rates well below the $550/month level, making the change seem like a no-brainer to
thousands of customers.
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.
"I am very satisfied with my new XO dynamic T1" added Mike McLoude, a small business
owner in Santa Monica, California. "The flexible nature of the system allows me to
conduct business with the same efficiency as many of my bigger competitors, for less
than what they pay." Mr. McLoude is not alone - many Californians are seeing the
technology light and taking the leap of faith away from traditional TDM.
Dynamic integrated T1s are a fairly new phenomenon. Unlike their analog
counterparts that can never deviate from their initial set up configurations,
dynamic T1s are able to convert voice phone calls into data packets and
them prioritize their delivery through an all-digital trunk. The ability
to break everything down into the lowest common denominator (digital)
allows the system to change on-the-fly to reclaim phone lines for high
speed Internet the second the phone call is terminated. An integrated T1 essentially
provides the end user the same service as one data T1 line and one
voice T1 line, for half the cost.
Recent advances in technology, fostered by competition from growing CLECs, is bringing
integrated T1 services to small business everywhere. And the trend doesn't look like
it will change anytime soon. CLECs continue to grow their networks, offering more
advanced services like metro ethernet, MPLS, and more. Expect innovation to continue on its upward spiral as the CLECs continue to expand
their footprints as well as their customer bases. Barring any funny stuff from the FCC,
the CLECs will be here to stay. Sorry Ma Bell.
