PRACTICAL IMPLEMENTATION AND PACKAGING TECHNOLOGIES FOR A LARGE-SCALE ATM SWITCHING-SYSTEM

This paper describes the practical implementation of a trial large-scale ATM switching system and packaging technologies. First, the architecture of the ATM switching system is discussed with an emphasis on system scalability. We introduce a building block architecture, in which switching capacity can be expanded in a modular fashion. Next, we look at the design of the ATM switching system including the ATM switch element. Then, the implementation of the VLSI's for the ATM switch which realize a highly modular system are explained. Bit-slice techniques are effectively used to realize a high-speed switch element as a CMOS VSLI chipset. Finally, we present a new edge-to-edge orthogonal packaging technique.
