Well I have deployed x2 in over 14 POP's and have had no problem. Let me
point out some problems with my K56Flex tests. First the Flex folks
created an early ROM version of the chipset and later the RAM versions.
Those modems using the ROM (Hayes Accura) will almost never connect to an
Ascend 4048. Many other problems are also major ones that K56Flex needs to
work out. Yes everyone but USR, 3Com, (Supra), (Cardnial) have gone to
56Flex. That is three makers of the chipsets, (they interoperate, but
trust me they are not 100% compatible). Then you have dozens of modem
manufactures making either ROM or RAM versions of the modem chipset, and
then on the ISP side you have a few dozen makers making different firmware
data pumps, and you have a major screwup!

Yes USR tech support stinks. 3Com's has always been great. I have finally
found resources in USR that make it very easy to get support. With USR
making the modems and the terminal servers for the ISP the quality control
is much higher. Remember the first 9600's, the 16800's the 19200's,
etc.... IN EVERY CASE USR upgraded to the standard once the rest of the
world came around. x2 will have more to say about the ITU standard being
reached than you think. More ISP's are deployed with x2 than K56Flex
today, and the reason is simple. x2 works reliably and right now the smart
ISP is slowly deploying K56Flex and working their technical support staffs
to death with interoperability issues. Don't beleive it? Go ahead and see
for yourself. With x2 and USR the cost per port is lower and better
quality than any other.

One other point. Everyone is talking about upgrading via a flash upgrade
the modems to the standard once accepted. Would you and do you want to
trust a company that has never flashed upgraded modems in the filed or
trust USR that has been successfully upgrading Courier modems in the field
for almost 10 years? I know this is beginning to sound like a USR
commercial, but let me tell you if I were in your market, you would be
losing dozens of customers per week to me. Ask my competition!
