Luke:
Thanks for the information.... I was down in Middletown at the end of last year and met a number of the 35 or so Globespan team members. I was able to see the testing room, modem building area and talked with John M. about CAP and some of the advantages of CAP.
The BIG question that keeps arising in the AMTX ,WSTL ,ORCTF and AWRE threads, deal with the distance/performance issue. Granted CAP does have a number of advantages of size, power, functionality of a single chip that supports XDSL,..., but the distance/performance keeps coming up.
The perception is that DMT outperforms CAP when noise is introduced. I wish I could read your white paper on the CAP performance/distance subject. The lack of information in this area makes many of us draw conclusions on what marketing/PR types print and say. This is why the Teledotcom evaluations are so important to many of us. You have modem A and B tested on the same CSA 12,000ft line to settle this issue on performance.
Here are a few other areas of concern:
1) Chip manufacturing..... Globespan keeps on stating that they have the only production chips available. My concern is that WSTL now has to write-off many of those chips 1.5Mpbs/64kbps production chips because the customers are willing to wait for the RADSL chips. Within the next 3-4 months MOT and ADI should start producing standard DMT chips.
2) All of the press releases never state distance. (ex) 12Mbps chip announced at the Atlanta Interopt show.
I have to go now... but as a novice in this area its seem Globalspan is making an attempt to hide certain information. I'm sure the DMT camp is doing the same.... It just doesn't seem as obvious to me.
Good luck at your new postition.... until later... |
