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

Homer, Michigan, Nov. 27 /Aaron Bashorun/ --
Higher productivity for small to medium sized businesses is just around the corner thanks
to commercial grade broadband services that are now being delivered at a fraction of their
previous cost. Due to the ever increasing competitive marketplace and a mad dash to consolidate
networks, telecoms are offering their premium business services to small businesses for a fraction
of what they used to cost just a few years ago. Businesses who use more than four regular phone
lines can now upgrade to dynamic integrated T-carrier circuits for the same price.
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.
To illustrate the types of decisions that small business owners are faced with
on a daily basis, we interviewed Glenda Probst, small business owner in Los
Angeles, California, about her recent move to a dynamic integrated T-1.
"I was in a quandary about how to go about expanding the number of voice
lines to my business. Before making the move to a dynamic integrated line,
I was using POTs lines. After the fifth line, my bill was above $300/month,
not including my $100/month DSL connection. Now, I have 12 pure digital
voice lines, 1.5 MB of broadband, and I pay under $400 for it. It was a major
upgrade in service with a reduction in total price. I only wish I'd learned
about this product sooner."
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.
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.
"For years I've played tug-o-war with the phone company who provided voice and data
service to my toy manufacturing company" commented Troy Bergfeld of Houston Texas.
"They kept trying to sell me services I didn't need, it took them months to finally
send me a correct bill, and I wasn't able to recapture bandwidth from my T1 line
when nobody was using the phone. Now that has all changed - my Telarus product
specialist recommending I give XO Communications a try. Now I use their FLEX T1
product and I pay less and get exactly what I want. I have even add another T1
seamlessly when the time comes for my business to expand."
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. Once a forgotten segment of the business telecommunication landscape, small to medium
size businesses are finally being serviced with products (like the dynamic integrated
T1 line) at prices they can afford. Gone are the days when the Bells can shove TDM
services down the collective throats of SMB's at prices that resemble a mortgage rather
than a telephone service.
