This setting is effective only when selectors 1 through 3 of WSW05 are set to "1,1,1." • Selector 3: Line current detection This selector determines whether or not the equipment should detect a line current before starting dialing. • Selectors 4 through 6: 2nd dial tone detection level These selectors set the detection level of the 2nd dial tone. • Selector 7: 1st dial tone interrupt detecting time This selector sets the allowable time length of an interrupt which should not be interpreted as an interrupt in the 1st dial tone dialing. 11

Frequency
band range
These
selectors
set
the
frequency
band
for
the

dial
tone
and
the

tone
(before
dialing)
to
be
detected.
This
setting
is
effective
only
when
selectors

through
3
of
WSW05
are
set
to
"1,1,1."
