Dynamic T1 Services Take Root

DRAPER, Utah, Nov. 13 /Patrick Oborn/ --
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.
At $50 to $75 per month, the average small business telephone customer could expect to pay
up to $750 for just 10 regular phone lines, which come with only a standard set of features
such as Voicemail, Caller ID, and Three-way calling. From 2000 to 2005, the cost of a
dynamic integrated T1 line was well over $800, making it an unattractive option from a
pure cost point of view. However, that paradigm has changed with the introduction of
sub-$400/month price plans and features that make the old POTs lines look pre-historic.
There are two basic "integrated" DS-1 configurations, analog and digital. The 24-line
bundle in which they come is termed a "trunk". The main difference between analog and
digital trunks is their flexibility. With digital trunks, voice lines not in use
can be dynamically reconfigured to carry data traffic, so they don't sit idle.
Analog trunks on the other hand can not change their function once configured
by the service provider. Data channels remain data channels and the same for
voice channels, even if 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.
Evolution has lead to a better, cheaper alternative to TDM services that the Bells were
peddling for decades in a vacuum of competition. Now the industry, lead by the innovation
and great business practices of the CLECs, seems to have turned a corner - leaving the
incumbents playing catchup. Obviously, the main benefactor of all of this competition
is the small to medium size business - a segment of the market that was taken for granted
until today.
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.
