Option 11C and 11C Mini Technical Reference Guide
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 Table 50.
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 Table 51.
Reference frequency:
• 1020 Hz µ-Law
• 820 or 420 Hz A-Law
