•
First 16-bit word of an ATM cell.
The ABM-3G does not interpret these bit fields, but copies them into ATM cells that are
inserted during AAL5 packet segmentation process. Inserted cells are forwarded to the
ABM-3G like any cell received by the respective UTOPIA Interface. Thus the bit field
usage must comply to the selected LCI mapping mode in the particular application.
