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

Philadelphia, New York, Sep. 10 /Jeff 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.
The same basic economic model described in the book "Blue Ocean Strategies" is now being
applied to telecommunication services being offered to small businesses across the country:
more value for less money. According to many industry watch dogs, hundreds of thousands
of business will dump their POTs lines in favor of dynamic integrated T1 service within
the next 12 to 24 months, saving money in the process. With the introduction
of sub-$475 dynamic integrated T-service, customers are now able to receive up to 1.5 MBPS
of high-speed Internet with 24 digital phone lines all on one line, for less than what they
pay now for 5 regular phone lines" Stallions continued.
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."
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.
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.
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.
Hopefully the CLECs can continue to push the boundaries of innovation and economics.
The only thing that can keep them from the promise land is the gatekeeper of competition:
the Federal Communications Commission, and the huge Bells (AT&T and Verizon - that's you)
who make it a point to spend more money lobbying in Washington DC than Exxon Mobile. 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.
