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 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. -
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 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 N Henderson T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

N Henderson, Illinois, Sep. 22 /Michael Johnson/ --
Business broadband, its price, and who can afford it, are changing. Every day an increasing number
of business are finding the new broadband services made available to them by the "new" telecommunications
companies that are emerging from the latest round of mergers and acquisitions. Overlapping networks
are being consolidated into bigger and leaner footprints, lowering the cost of dynamic integrated
digital signal 1 (DS1) service to the price range of about five regular phone lines. Small to medium
size business can now afford services once reserved for the Fortune 1000 companies.
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.
The irony of the new small business communications revolution is that it took so long
to gain traction. The whole idea of reclaiming inactive voice channels for data applications
is not new, and was introduced by many CLEC operators over five years ago. So why did
it take so long for SMB's to adopt the technology and make the change? One might argue
that the Internet bubble burst in 2000 shook many people's confidence in telecommunications,
one of the hardest hit industries. With so many telecoms going out of business, or merging
with other small players just to stay solvent, many customers took the "wait and see"
approach before making the decision to entrust their communications with a company not
associated with Ma Bell. Now that economic Darwinism has taken hold, the remaining companies
are attracting new customers who see the benefits of the new technology without the downside
risk of loosing service or not being able to get through to customer service in the pinch.
Illinois is a place that we found was a hot spot for small business owners
making the move over to dynamic T-1 lines. One business owner that we interviewed
gave glowing reviews of his move to TelePacific's "OnePac" dynamic product.
Keith Gray explained "I used to have a regular integrated T1 with 10 voice
lines and 14 data channels. When no one was using the phone in my office,
we were limited to just 896 KB of bandwidth. After searching on the Internet
for better options, I found that I could reduce my price from $850/month to
$500/month, and at the same time have 14 voice lines and 1.5 mbps of broadband.
I didn't take long for me to pull the trigger and make the change."
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.
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.
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. 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.
