Method 1
With a noise signal corresponding to CCITT recommendation 0.131 applied
to the input interface, the total distortion measured at the output interface lies
above the limit given in Table50.
Method 2
With a sine wave at the reference frequency is applied to the input interface,
the total distortion measured at the output port interface lies above the limit
given in Table51.
Reference frequency:
•1020 Hz µ-Law
•820 or 420 Hz A-Law
