The Evolution of Integrated T1 Service

MASKELL, Nebraska, Jul. 07 /Zackary Smith/ --
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.
"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."
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.
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.
Until deregulation allowed smaller, hungrier telecommunications companies the
ability to compete, the United States was stuck with technologies that were quickly
becoming out of date. Now that the Bells actually have to innovate to keep up with
the smaller CLECs, customer everywhere are reaping the benefits.
