Ta=25
Input = Digital code sequence for
0dBm0 signal at 1020Hz
f = 0Hz to 3000Hz
f = 3300Hz
f = 3400Hz
f = 4000Hz
Ta = 0
Sinusoidal test method; reference
input PCM code correspond to an
ideally encoded -10dBm0 signal
PCM level = -40dBm0 to +3dBm0
PCM level = -50dBm0 to -40dBm0
R
Norminal 0dBm0 level is same as
4 dBm ( 600 )
Max overload level ( 3.17dBm0)
Ta = 25
Input at GSx = 0dBm0 at 1020Hz
f = 16 Hz
f = 50 Hz
f = 60 Hz
f = 200 Hz
f = 300 Hz - 3000Hz
f = 3300 Hz
f = 3400 Hz
f = 4000 Hz
f = 4600 Hz and above,
mesaure response from 0 Hz to 4 KHz
