Description: ATM network interface addressing mode. Valid values for this field are: HEC - The Header Error Control (DEC) is an 8-bit field and the fifth byte in the header of an ATM cell. The HEC value is calculated from the first four bytes of the cell header. If an error occurs in an ATM cell header, it will be detected in the HEC field. Cells with HEC errors that can not be corrected are discarded by the receiving node. The HEC field can also be used to determine the boundaries of a packet for cell delineation. Valid for ATM OC-3, ATM UTP, ATM T3, ATM E3 with G.832/G.804 framing. PLCP - Physical Layer Convergence Protocol. Each cell is preceded by a 2-byte framing pattern (A1, A2) to enable the receiver to synchronize to the cells. Valid for ATM OC-3, ATM UTP, ATM T3, ATM E3 with G.751 framing.
