5.1.6.4
In Mapping Mode ‘Infineon’, the ABM-3G expects a 16-bit local connection identifier in
the location of the VPI field and the UDF1 byte as shown below. Mapping Mode ‘Infineon’
is configured via bit field LCIMOD(1:0)=’10’ in Register

Since the ABM-3G supports 16 K connections, the MSB bits 15 and 14 of the LCI must
match the selected quarter segment. Otherwise the cells are automatically forwarded to
the global real time bypass queue (Queue 0) and may be handled by a subsequent
ABM-3G device.
5.1.6.5
In Mapping Mode ‘Address Reduction’, the ABM-3G generates a 16-bit local connection
identifier based on the marked bit fields. Mapping Mode ‘Address Reduction’ is
configured via bit field LCIMOD(1:0)=’11’ in Register
