SORTING UNIT FOR A SWITCHING NODE WITH MULTIPLE DIGITAL SWITCHES FOR FAST ASYNCHRONOUS DATA SWITCHING NETWORKS

The switching node has a multi-level, mixed connection structure, for example, in the manner of a so-called Banyan tree structure, which forms a complete bundle, i.e. in such a way that each input of the switching node can be connected to each output of the same. The digital switching networks are designed as self-routing sorting units, which are a multi-layer, through-connecting arrangement with 2m-1 beta element columns each containing m beta elements ( beta ), where 2m is the number of inputs or outputs of the sorting unit and m is a power of 2. The sorting unit is divided into a first sub-unit, functioning as a distributing unit, with m columns and a second sub-unit, functioning as a correcting unit, with m-1 columns. ……
