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 West Linton 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.

West Linton, Indiana, Nov. 03 /Richard Anderson/ --
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.
From 1997 to 2007, the average cost of a POTS (plain old telephone service) line from the
Bells has hovered in the $50 - $80 per month price range. During this same time period,
integrated DS1 (digital signal 1) lines - which is the equivalent of 24 standard lines -
have come down in price from $1000 per month to $400. Small to medium size businesses
who have more than 5 phone lines can now actually save money by upgrading their service.
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 early adapters of this new technology have realized a cost savings that helps
them be more competitive in the market space. By saving hundreds of dollars each
month, which equates to thousands of dollars per year, small businesses are able
to do more while spending less on their telecom bill. This savings allows for
hiring of additional staff, upgrading equipment, and other activities that make
the enterprise more productive and profitable. Many in the industry see the
lack of mass adoption of this new technology as just shear ignorance and/or
a lack of trust for telecom sales people.
One might think that, given the cost - benefit analysis of the integrated T1 value
proposition, more businesses would be changing over to the new platform. However,
the rate of adaptation is rather slow. Rob Butler, head of the Telecommunications
Research Institute, thinks that "phone companies have a problem with trust amongst
their user base. For many years, customers have dealt with increasing rates, long
hold times, and frustration in general. Now, it appears, the ice is finally starting
to melt and customers are opening themselves up to new technology.
Integrated T1s comes in two basic configurations: digital and analog trunks, with a trunk
being a 24-line (or channel) bundle. The newer, digital trunks, however, are able to
run both voice and data over the same channels. By assigning priority to the voice
traffic whenever it is present, a dynamic integrated trunk can provide the end-user
with a full 1.5 MBPS of data throughput if no phone calls are in progress. As more
voice lines are required, less data lines are available. Analog trunks are all
pre-assigned to either voice or data traffic, and do not reconfigure in the event
there is no voice traffic.
The recent progress made by CLECs leaves us thinking in hypotheticals. "What if the
Clinton administration wouldn't have passed the Telecommunications Act of 1996, requiring
RBOCs to lease their lines at reduces rates to the CLECs?" "Will the FCC continue to
enforce this law, or will it be overturned by the powerful AT&T and Verizon lobbyists?"
It is impossible to know either way, but for the time being we can just be grateful
that the industry has evolved to the point were small businesses can actually benefit
from telecommunications at an affordable rate. 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.
