Header octets three and four of first ATM cell of AAL5 packet.
The ABM-P SAR unit does not interpret these bit fields, but copies them from ATM cells
that are extracted during AAL5 packet reassembly process. Extracted cells are
forwarded from the ABM-P like any cell to be transmitted by the respective UTOPIA
Interface. Thus, the bit field usage depends on the selected LCI mapping mode in the
particular application. From scheduler point of view the reassembly unit is addressed as
UTOPIA port number 30
VCI(11:0)
or
LCI(11:0)
