SDH Transmit/Receive Jitter Amplitude Accuracy
STM-16 Optical
50 .Change Transmit/Receive Rate to STM-16 Optical with AU4-16C Mapped Bulk
Filled 2^23 PRBS Payload. Check and adjust the optical power as necessary.
Ensure Jitter is OFF and Calibration Pattern is OFF, then repeat steps 6 to 43
using the information in the Table below for STM-16.
51 In the case of dual wavelength option units set to the alternative wavelength
(1550nm) and repeat steps 6-9 for each rate.
