>>seems to me that VDSL, being asymmetric, would likely remain targeted toward residential customers. business customers need at least as more if not more upstream bandwidth vs. downstream: VOIP and video telephony are symmetric, and most companies have high-traffic websites serving content to the web. "reversed" VDSL would better fit business bandwidth requirements.<<
Mark, I'm not so sure about that. Once you approach 52 down, and 6.3 up, I think that even the low speed side of the asymmetrical VDSL connection can accommodate just about anything you've mentioned. The higher speed on the downstream should allow for multiple TV sessions taking place, which I don't think anyone has intentions of sending in the reverse direction.
Reversed VDSL? How would that work, exactly? And what forms of media would you propose to support it, and to where?
VDSL, where it is being deployed successfully, such as in Next Level's and Alcatel's, is delivered to the pedestal over fiber, and then distributed to the home over either coax or twisted pair. In other words, it's not a technology that can sustain itself in the absence of the other elements, most importantly, a Sonet Ring to the pedestal or other device which is very close to the user.
