! I have witnessed a good link between TB sites average in excess of 1730 cps.

We're getting a BAD throughput too.  About 550 CPS on a TB+ for a 
trans-atlantic link.  This really sucks!  A local FIDONET Sysop with
an HST claims he gets 1000 cps on average on trans-atlantic calls!  I 
thought the TB was a vastly superior modem.  Either I was wrong, or my
setup is wrong.  We have s120=12 (supposed to be an undocumented feature
for trans-atlantic links), but still get only 550 CPS.

Any help would be appreciated.  I would expect to get OVER 1000 CPS
with a trailblazer, or else maybe we should switch to an HST.

thanks
