Each network tone is defined as

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 duration (in milliseconds)

c1off is cadence one off duration (in milliseconds)

c2on is the cadence two on duration (in milliseconds)

c2off is the cadence two off duration (in milliseconds)

c3on is the cadence three on duration (in milliseconds)

c3off is the cadence three off duration (in milliseconds)

f1 is the tone #1, 300-3000(Hz)

f2 is the tone #2, 300-3000(Hz)

f3 is the tone #3, 300-3000(Hz)

f4 is the tone 34, 300-3000(Hz)

p1 is the attenuation index for tone #1, 0~31(0=3dB, -1dB increments)

p2 is the attenuation index for tone #2, 0~31(0=3dB, -1dB increments)

p3 is the attenuation index for tone #3, 0~31(0=3dB, -1dB increments)

p4 is the attenuation index for tone #4, 0~31(0=3dB, -1dB increments)

Two network tone definition samples are shown below.

2. A New Zealand Busy tone (400Hz with a cadence of 500ms on and 500ms off (repeat)) is defined as

1,0,500,500,0,0,0,0,400,0,0,0,10,0,0,0.

i) Speakerphone Mic Input Gain – This speakerphone Microphone gain can be tuned to optimize its

acoustic performance via this field. Four gain settings are available: 8, 12, 16, 20 dB.
