ADSL has been of interest to me for the past couple of years because it
enables high-speed data on a single pair of local copper loop. It is phenomenal
how it can allow voice and data to run concurrently over the same pair of wire.
The article of choice for this report is in the subject of ADSL technology and
the integration of the chip sets. Within these five pages the author examines
the design methodology that Alcatel has used to develop their mixed signal “chip
set-asynchronous digital subscriber line (ADSL)” and the chip implementation
environment. I believe that software emulations of hardware components are a
more reliable and cheaper way to design devices. Although I have no experience
with device designing, it is interesting to me how software emulation can
facilitate the engineer with a fast editing environment. There are no soldering
and complicated physical barriers involved. When the Alcatel design team tested
the system in a worst-case scenario, restricting its range of voltage and
temperature, the simulation of just 10 seconds of initialization could have
taken days of simulation time. But Alcatel resorted to using an emulator for
fast debugging. The emulator, in contrast with the simulation, would only take a
few hours, not days. A very important aspect in new technology is to permit the
ease for product enhancements. In a broad sense, many times there are new and
more efficient ways of implementing a certain design after its final release.
The author outlines in his conclusion that Alcatel completed a USB version of
the ADSL digital chip. That explains the ease and no hassle install of my ADSL
modem to my laptop. the writer outlines illustrates the Because of the
flexibility of the chip bus architecture, other digital back ends can be
integrated onto the chip.
