Dear friend!
This is the commissioning attribute of an ASON link.

Adaptive OSNR Equalization
Monitors the OSNR deterioration, and adjusts the EVOAs of add wavelengths at the transmit end to ensure the flatness of OSNR deterioration among all single wavelengths.
Enhanced Power Equalization
Monitors the optical power spectrum, and adjusts the EVOAs of add wavelengths at the transmit end to ensure optical power equalization among all single wavelengths.
Basic Power Equalization
Calculates the optical power using the function of presetting the OPA insertion loss for deployment to obtain the insertion loss between OTU and OA boards, between OA and OTU boards, and between OA boards, and applies the insertion loss to an NE to facilitate OPA adjustment.
Configuration and provisioning mean the same thing.
Thanks!
