has announced the addition of the "Bandwidth
Needs Analysis of the RBOCs' Advanced Access Architectures: FTTP and
FTTN" report to their offering.
The Advanced Access Architecture thrusts of the major US carriers as one
of the most important events in telecommunications history. As such, the
authors have been periodically issuing major reports on the FTTP/FTTn
activities of the RBOCs since it began in 2003. Earlier this year the
authors issued Advanced Access Architectures 2008 AT&T, Verizon, and
Qwest Plans and Forecasts, the most comprehensive of the authors reports
on this subject. In recognition of the wide interest and deep importance
of the FTTP/FTTN phenomena, the authors are now issuing a series of
reports that focus on narrower aspects of Advanced Access Architectures.
Specifically, this report focuses on the bandwidth needed in the access
area and on ways to get that bandwidth.
Bandwidth Needs Analysis of Advanced Access Architecture
Since Bell first decded to build outside plant, there has been a debate
as to the best way to extend service the final mile. The debate
continues now with the various FTTX schemes for bringing fiber to within
various distances of the customer. In some ways, the debate really has
not changed much it is still about the economics of each approach but in
a very real way, the debate is different now. In the past, this debate
was always about POTS and the economics of various way of providing it.
Now it is still about economics, but it is also about maybe even more so
alternative ways to meet requirements for bandwidth needed for some very
exotic services. The question is not just, Which is cheaper? Also
involved are such questions as, What services will I provide?" How many
of each service will the customer need? How much bandwidth do I provide
for these requirements? How will compression advances impact my choices?
The answers to these questions guide the technology choices for the last
mile now, at least, as much as economics.
While this was never a simple debate, the addition of the new unknowns
about service requirements makes it a much more complex consideration.
To see how complex, one just needs to note that the three (now two)
major telcos - Verizon, AT&T and BellSouth have studied this issue with
all of their great resources and come up with three completely different
So, what is the interest in the bandwidth capacity of local (access)
networks? Several years ago, this would have been a moot point, with the
answer being that the needed bandwidth was only what was necessary for a
voice call. Now the local loop is carrying data and, most recently,
television. With the desire for high- speed data driving
ever-higher-bandwidth data services, and with video now in the equation,
the need for bandwidth is a much more complex question.
