Those are actually the V.8 Call Indicate tones, and although they are
indeed part of the V.34 spec, USR now disable them by default, because...

Seems that the Viper's tone discrimination could be better, as I recall the
fax CNG tones and V.8 CI tones being only 200Hz apart (1100Hz & 1300Hz
perhaps?).  Couldn't be bothered checking the manual, but I'm sure you get
my drift.

There will be an S-register which disables V.8 CI tones (not V.8
altogether, which is indeed a necessary part of V.34).  Find it, and USE
it.  :)

Nope, you can safely leave them disabled.  Most people do anyway.
