You are comprehensively mangling together two completely separate issues.
That bit was discussing if you really do have a 'poor line' between you and
Paul. In fact it appears its not really that poor at all, and the evidence
for that is the Sportster/Courier stats on that call.

And in fact even your results with the Sportster V34+/M34F show
that it cant be poor, whatever the Sportster stats claim.

BG> So much for the theory that NetComm/NetComm would give the best connects.:)

No one ever claimed anything remotely like that either, just
that it has to be tested before you can claim that USR/USR is
better, AND we were discussing the handshaking problem anyway.

Cant be poor if it got the 28800 speed Bill. A line
which gets the maximum V34 speed is no way a poor line.

BG> That's crap.  An Rx level of -32dBm with a line quality of 24 !

WITH a 28800 session. Nice theory Bill, pity about the evidence tho.

BG> How many times do I need to repeat that Paul's
BG> lines are nearly as bad as mine here ?

You can repeat it till you go blue in the face if you like, the
EVIDENCE of Russ's calls to Paul with Courier/Courier figures
shows that the claim that Pauls line is poor is tripe. YOUR
line is quite a bit WORSE than Pauls when tested the same way.

And when you can get 28800 connects between you, its completely
silly to call that a poor line coz if it was, it would be LOWER.

BG> Dave's is considerably better though.

No one has ever disputed that the bulldogs line, and Russ's FNQ line
are MUCH better than normal. That doesnt mean that any line which is
worse than those two is 'poor' tho, just that its not immaculate.

And if a 28800 connect can be achieved on a modem that has that as
its maximum speed, it cant possibly be 'poor'

Notice that you didnt even get one of those to Dave,
whatever the RX level and EQM were listed as. Funny that.

BG> An Rx level of -23dBm, with a line quality
BG> of 9, which is still extremely marginal.

Its bullshit Bill, as Sportster V34+ to Courier V34+ on that
session shows. Nothing remotely like 'extremely marginal' about it.

Just fucked assumptions about Rx levels and EQMs blown
totally out of the water by the speed achieved.
