True, particularly when you cant actually rely on what the USR claims
to see as the line conditions. You really do need to be able to see
that the line is showing the bad state, apply some completely separate
test equipment to the line to see what the actual line is doing.

DH> Neither USR I have is capable of holding that line at the moment for
DH> longer than 2 minutes maximum.  _However_ both negotiate happily up
DH> to 28.8, and report s/n at over 35db, until the fault hits.

RS> Corse you dont actually KNOW that the S/N is valid in the fault
RS> situation, just that thats what the USR claims is the S/N.

DH> Point taken.  The USR has gone gaga.

Yeah, in fact there is a distinct possibility that the line fault
condition causes the USR to have a massive brain fart, thinking that
the S/N has gone obscenely pear shaped in one direction only, when in
fact its done nothing of the sort, atleast on the obscenely, and so
it just mindlessly reduces the symbol rate in that direction BECAUSE
it erroneously thinks that the S/N in that direction is obscene.

DH> Some of the readout figures are simply impossible - for instance,
DH> the far echo goes to several thousand db of loss on some of the logs.

Yeah, pretty powerful evidence.

DH> It is apparent there's interference - and that the interference affects
DH> only one direction. That's about the totality of accurate information.

Yeah, and that would explain why there is a such a wide variation in
how different modems handle that particular interference, unfortunately
the USR has such a massive brain fart that it does a lot worse, thinking
that its doing the appropriate thing in the circumstances, when in fact
its just got it wrong no the line conditions.

DH> I think I'm gonna take up golf.
DH> Easier, cheaper, and more likely profits..:-

RS> Life wasnt meant to be easy boy |-)

DH> Yeah, but this?  :-)

I think modems were a plot cooked up by the commies
to drive us all mad, then they will just take over |-)

Look what its done to Lew |-)
