CDSL is still dead

<<1. It is still in the early design stages
To be introduced in 98. (Purportedly not that hard to get 1Mbps)

According to the Nov 4 EE Times article,
<<At a meeting of the International Telecommunication Union's Study
Group 15, hosted here by Globespan Technology Inc., Rockwell introduced
some core concepts for what it calls Consumer DSL, or CDSL.
The proposal was made to the G.ADSL Lite working group within Study
Group 15, which is attempting to find ways to reduce the costs of asymmetric
DSL deployment. Rockwell is examining concepts for using
frequency-division multiplexing modulation concepts similar in principle to the
discrete-multitone modulation used by one branch of ADSL adherents>>
and further in the article
<<The G.ADSL Lite effort is still in a very early stage, and Rockwell is
prepared to accept the fact that alternative modulation methods, perhaps
based on concepts other than DMT, could win out. Rockwell has been
working on its frequency-division concepts for 15 months. Implementation
requires the use of Rockwell intellectual property at the physical layer and at
other layers in the protocol stack, though Halim stressed that the company is
prepared to meet all ITU requirements, and will make any licensed aspects of
CDSL available at reasonable fees.>>
Unless your sources know better, it sounds like Rockwell was floating a trial balloon and hasn't committed any tangible resources to this project yet. Since this balloon has been effectively trumped with ADSL Lite, I don't think that we will hear from it again.
I would be really curious if your sources find out anything differently. I am sure that we have only seen the tip of the iceberg of the gamesmanship that has been occurring between COMS (3Com, USRX), Aware and Rockwell over this issue. Aware clearly had advance knowledge of this proposed project and dedicated funds and personnel to produce a demonstrable model. |
