Abstract

The paper presents a high performance ATM Switching Element with programmable switching capacity from 8 x 8 to 32 x 32 links, each at 311 Mbit/s. The 8 x 8 component is a single fully CMOS IC, the others can be obtained by properly connecting the 8 x 8 basic elements in Multichip Modules. It is shown how to connect them in order to avoid blocking problems, to increase the shared buffer availability and to improve the global system capacity of a factor of 2 or 4. The expanded Switching Element is a single component in terms of functionality and represents a single-stage in the ATM Switching Fabric. A MCM 16 x 16 Switch is also described and its features are presented. Both the components find an industrial application in the Italtel Cross Connect UTXC, which, using these elements, can provide systems from 5 up to 160 Gbit/s.
