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. -
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 Recycle T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet
Definition 3. -
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 4. -
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.

Recycle, Texas, Aug. 29 /Kiersten Thomas/ --
Small businesses all over the country are discovering a whole new universe of broadband access.
As the price of commercial-grade telecommunication services continues to drop, more and more
enterprises are starting to drop their plain old telephone service lines in favor of all-digital
T1 trunks that deliver voice and data over the same connection. These new enhancements were
made possible by the increasing pace of consolidation in the telecommunication industry along
with the increasing value bigger phone companies can provide.
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 old-school integrated T-1 was analog in nature, and came with 24 configurable
channels (called a trunk) which could be configured to carry either voice or data
traffic. The new "dynamic" trunks are all-digital and can change on-the-fly
to carry either data or voice traffic. This comes in handy when none of the voice
lines are in use - all channels can revert to carrying data traffic, giving the
end-use a full 1.5 MBPS of broadband. Each phone call requires only 64K of bandwidth,
so even a small handful of calls only slows down the data connection by a nominal
amount.
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 think the telecom industry in general has turned a corner" opined Jerry Gold of
Boston, Massachusetts. "They have finally developed products that are understandable
by the industry outsider and, thanks to competition, priced these services in a
range that most small businesses can afford. For over 20 years I dreaded dealing
with 'the phone company'. But now that I've switched over to One Communications,
my integrated T1 is doing everything I need it to, for under $450/month. One
actually answers their customer service calls and makes me feel like I'm part
of their family. It was a long time coming, but I'm finally able to end the
fight with the phone company so I can focus on my sports memorabilia store."
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.
As the competitive local exchange carriers continue to compete by introducing new and
exciting products at prices most small businesses can afford, they are coming up against
increasing resistance from the RBOCs who are forces to lease their own copper lines
to these CLECs at reduced rates. This reality has the CLECs rushing to deploy their
own networks and fiber routes, but the FCC may ultimately relax the mandate - leaving
all of us wondering how long the party is going to last. Until deregulation allowed smaller, hungrier telecommunications companies the
ability to compete, the United States was stuck with technologies that were quickly
becoming out of date. Now that the Bells actually have to innovate to keep up with
the smaller CLECs, customer everywhere are reaping the benefits.
