David,
This is in regard to your post at the other USRX thread: techstocks.com (Both articles posted are great, and should be made available here)
The first article is especially interesting to me since it attempts to answer the question of what kind of performance can be expected of the 56 kbits/s technology, if people are having difficulties connecting at 28.8 or 33.6 kbits/s speeds due to quality of phone lines. In other words, with non-interoperatability issues put aside, is 56K real for most internet users, or is it as John Force said, as quoted by Barrons, merely a way to make the poor put more money into the pockets of the rich? This question has been bothering me for a while now. Therefore, it was very reassuring to read:
'Enough preliminary network testing has been done to safely conclude that close to 56-kbit transmission speeds should be able to be achieved 50 to 60 percent of the time in the United States.'
I wish the article said more about what speeds a 56k modem would connect at if a 56k connection is impossible because of phone line noises. What are the incremental speeds a 56k modem will attempt to connect before it kicks back to V.34?. Note that we are still getting a much faster connection with 'close to 56-kbit transmission speeds' than with V.34, even though we might only be getting it for '50 to 60 percent of the time'.
Do you or anyone else have any insight on this?
Thanks.
