System Aspects and Realization of Wide-Band Switching in the Local Area

This paper discusses the functional components of nodes in wide-band switching networks. Emphasis is given to the local area where the system´s architecture can be considerably simplified. The experimental results are related to this type of application. They demonstrate the availability of all system components for medium-size systems (up to 240 lines). A 16 × 16 highly integrated switch is described as a building block for greater systems. It is capable of handling data streams up to 380 Mbits/s. The maximum jitter amplitude observed after passing one cross point is 0.25 ns.
