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

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.
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.
"When we moved into our new location here in Los Angeles" commented John Baker, a
small business owner in San Diego, California, "we feared having to sign up for
commercial telephone and internet service. Until about a year ago, the services
being offered to us were TDM, which doesn't come cheap. Thankfully our Telarus
commercial telecom broker recommended that we give TelePacific a try, and we did.
One year later, we've never had an erroneous bill, our phone and data are all on
one single dynamic T1, and we can focus on what we do best - brokering mortgages."
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 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.
South Carolina, ordinarily not known for its telecom prowace, has been a hotbed
for businesses making the move to dynamic telecom lines. One local business
owner - Linda Peterson - who operates a travel agency, recently told us that
"I never expected the phone company to come out with anything that would
help me lower my costs. On the contrary. Ma Bell has had a history of raising
my rates and making my life difficult. When I heard about the XO Flex package
(offering 10 dynamic voice lines and 1.5 mbps of high speed Internet) at a price
of under $500, I couldn't move over fast enough." Since then Linda reported
a $150/month savings in her telecom expenses.
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. Change does not happen quickly in an industry as so heavily regulated as Telecommunications.
Recent industry consolidation has provided huge alternatives to the incumbents, who
are now under pressure to keep up with new technologies while charging better prices
to retain and attract new customer bases.
