5.1.6.2
In Mapping Mode ‘VPI’, the ABM-3G expects a 12-bit local connection identifier in the
location of the VPI field. Mapping Mode ‘VPI’ is configured via bit field LCIMOD(1:0)=’00’

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.
