Hi Dave,
>> You're
right that there's nothing extraordinary about that (and the latest generation CAPs
have excellent cross-talk protection with their trellis coding).
Says who, Globesan? They are a PR organization not a technical organization (IMOH). What else would you expect them to say? Or maybe Bell Atlantic. Now there is an
unbiased opinion. Telechoice said they own an interest in CAP.
Excellent cross-talk protection compared to what? The old CAP stuff? I would hope so. They have had 3 years back at the drawing board applying the Band-Aids, it better be "excellent". How does it do against DMT? I like the Telechoice dudes but I know of no other test facility in the world other than the one at Bellcore in New Jersey that can do a fair, unbiased, comparison of these technologies. We know the result the last time they did it. Other than the fact that the licensing rights to this "enabling technology" can generate enormous revenue for AT&T, why should the world have to deal with this second rate technology? They are using every marketing trick in the book to wiesel there way into the standard. Its all smoke and mirrors (very expensive ones). Dave I've read your posts and I think you are well informed, contribute a great deal, and ask great questions. I feel you refuse to read between the lines when it comes to this PR campaign.
>>The only place I hear this noise to signal ratio criticism of CAP is on the Amati
threads. The trailing telcos, the Bell Atlantic customers who were thrilled over their
VoD with Westell Flexcaps last February (in northern VIrginia), the experts at
Telechoice, industry journalists in EE Times, etc., no one else seems to have noticed
this.
I don't think a couch potato is going to do anything to stress the weakest link in the CAP system, the upstream. If you give them 9600 baud they wouldn't know the difference. With a work at home application, .7 Mbs is looking small. How long do you think its going to take Billy Gates to come up with a "killer app" that that will require enough bandwidth were these "extraordinary circumstances" aren't so extraordinary (bandwidth in both directions, with noise, at a distance). This is where the RBOC will make $$ - selling bandwidth. If they don't the CAP's and ISP's will. I have to say that Bell Atlanic is doing a good job at exploring future markets. They may be light-years ahead of the rest of the RBOCs.
Buy the way, I don't think FlexCap was available last Feb. You
must mean the other CAP, you know, the one without the
Band-Aids but yet is "here today". I get confused by the hype too.
Later
