Each tone listed above is defined in the following format:
nc, rpt, c1on, c1off, c2on, c2off, c3on, c3off, f1, f2, f3, f4, p1, p2, p3, p4
Where:
nc
is the number of cadences
rpt
is the repeat counter(0 - infinite, 1~n - repeat 1~n times)
c1on
is the cadence one on (in milliseconds)
c1off
is the cadence one off (in milliseconds)
c2on
is the cadence two on (in milliseconds)
c2off
is the cadence two off (in milliseconds)
c3on
is the cadence three on (in milliseconds)
c3off
is the cadence three off (in milliseconds)
f1
is the tone #1 frequency (300Hz-3000Hz)
f2
is the tone #2, frequency (300Hz-3000Hz)
f3
is the tone #3 frequency (300Hz-3000Hz)
f4
is the tone #4 (300Hz-3000Hz)
p1
is the attenuation index for f1, 0~31(0=3dB, -1dB increments)
p2
is the attenuation index for f2, 0~31(0=3dB, -1dB increments)
p3
is the attenuation index for f3, 0~31(0=3dB, -1dB increments)
p4
is the attenuation index for f4, 0~31(0=3dB, -1dB increments)
For example, the tone definition for a tone of 450Hz with a cadence of 700 ms on and
1000 ms off is
1,0,700,1000,0,0,0,0,450,0,0,0,20,0,0,0
