I assume that the CFC variable represents the filter class, i.e CFC 60, CFC 180, CFC 600 and CFC 1000. I think there is also a way to have a customer defined CFC, so that would replace the CFC with whatever number is entered by the user in the dialog.

And to represent it in standard ISO-MME file (16th position):

CFC 60 = D

CFC 180 = C

CFC 600 = B

CFC 1000 = A
