The concept and implementation are presented for a demonstration broadband switching network and a TV switching network for 70 Mb/s to be used in a future broadband integrated-services local network. The basic component for both switching networks, a 16*16 switching element, was developed using a CMOS gate-array in 2- mu m technology. The low-power consumption (<500 mW) of the switching element creates the possibility for a condensed arrangement of a switching network. It is possible to install a five-stage switching network with 4096 inlets and outlets in one 19-in rack. Results of the development of the switching element, the broadband switching network, and the TV switching network are given.
