5.1.6
The following sections describe the cell format expected by the ABM-P, depending on
the selected mapping mode. Transmitted cells have the same format.
The ABM-P may modify user-cell field ‘EFCI’ and the LCI field (VC-Merge function),
depending on the configuration. In OAM cells, bits ‘CI’ and ‘NI’ as well as Function
Specific fields may be modified. For internal use, also field UDF2 may be modified. The
CRC10 field gets recalculated accordingly.
