Source: The source of the cell, encoded as follows:
0 : Input Cell Interface, Microprocessor Cell Interface, or Backwards Cell Interface
1 : Generated RDI or Bwd PM Cell, or Looped-back OAM-LB cell. It is intended that all of
these cells be passed to the opposite direction S/UNI-ATLAS-3200.
NNI: Indicates the connection is associated with a Network-Network Interface (NNI). A logic 0
means the connection belongs to a User-Network Interface (UNI).
VPC: Indicates the connection is provisioned as a Virtual Path Connection (VPC). A logic 0
means the connection is provisioned as a Virtual Channel Connection (VCC).
OAM_Type: A logic 1 identifies a segment OAM cell. A logic 0 identifies an end-to-end OAM
cell. This bit is only valid when the cell type indicates one of the OAM types.
TYP[4:0]: Cell type. This field is encoded as follows:
