Naoki Fukuda, Shuji Yoshimura, Satoshi Kakuma: Address decision system having address check system. Fujitsu, Staas & Halsey, October 17, 1995: US05459743 (40 worldwide citation)

In an address decision system in an ATM exchange, a table memory stores data showing relationships between VPI/VCI values and addresses. A latch circuit latches a VPI/VCI value contained in a cell transferred via a cell highway. A comparator circuit compares the VPI/VCI values stored in the table me ...
