VPI/VCI of an ATM cell is translated into an internal Id by distributing
VPI/VCI entries into sections in a table according to a portion of each VPI/VCI
entry. A section to be searched according to the portion of a VPI/VCI of the received
ATM cell is selected; and a search over the selected section is performed to find
an entry corresponding to the VPI/VCI of the received ATM cell. An internal ID
corresponding to the found entry is outputted.
