It seems to me that k56Flex is winning out over x2.
For every pro-k56flex write up, there is a pro-X2 write up. It depends on who's FUD you believe. ;-)

K56flexT is a trademark of Lucent Technologies Inc. and Rockwell International Corp.
A trademark? Show me an international ITU-T standard that is owned by a vendor and I'll eat my shorts.

How does the Open 56K Forum standard compare to other standards like U.S. Robotics x2?
I have heard good things about each when compared to current 33.3 limitations of existing standard. As far as who does 56K better, I won't attempt an answer. I do not have any statistics, other than those I read from the two camps....each of course stating their's is superior.

The x2 protocol is not interoperable at 56 Kbps with the Open 56K Forum standard, which is based on K56flex.
No, your wrong.
The Open 56K Forum's implementation is not interoperable with the X2 implementation. <G>

However, x2 is a proprietary specification from U.S. Robotics.
And k56flex is proprietary. Name one standards body that has specified k56flex as a standard....Joe's PC shop does not count. The standards bodies are the following: ITU-T, ANSI, IETF (sort of), IEEE, OSHA, etc. This is no small issue.

Do you by chance remember V.fast "standard" modems .vs. hayes-standard-9.6-pingpong "standard" in that war on speed some years back?? Well guess what? Neither one was chosen to be the industry standard. All the FUD in the world could not make it work. They were merely evolutional weak links in the chain to a better technology leading to 28Kbps asychronous communications.
