55..11..44..22 SDH frequencySDH frequency
Touch the field to set Frequency OffsetFrequency Offset. If setting a positive value, the frequency
will shift higher side.
Example:
If setting -50 ppm to the frequency offset for STM-16 output signal, the bit rate
of output signal will be
2 488 320 * (1-50*10
-6
) = 2 488 195.584 (kbit/s).
