摘要： The switching network serves for the transmission of digital data signals within a broadband communication system. This switching network is thereby constructed of individual switching elements (KE) that form at least one multi-stage funnel due to a connection to one another. The section for the assemblies of the switching network is selected such that at least one complete funnel is accommodated on the respective assembly. The respective assembly thereby has its external data inputs provided with unidirectionally designed optical/electrical transducers (OML-E) and has its external data outputs provided with unidirectionally designed electrical/optical transducers (OML-S).

摘要： A process for obtaining coarsely crystalline pure ammonium sulfate from reaction mixtures which have been obtained by Beckmann rearrangement of cyclohexanone-oxime with sulfuric acid or oleum, by neutralizing the mixtures with ammonia at an elevated temperature, with the addition of recycled ammonium sulfate mother liquor, the concentration being so chosen that during the neutralization no solid ammonium sulfate precipitates, separating the crude caprolactam from the ammonium sulfate solution, crystallizing ammonium sulfate by evaporating the ammonium sulfate solution under reduced pressure, separating off the crystallized ammonium sulfate and recycling the mother liquor to the neutralization stage. The neutralization is carried out at from 80.degree. to 115.degree. C. under autogenous pressure and the ammonium sulfate solution obtained after separating off the crude lactam is evaporated under a pressure of from 200 to 600 mm Hg while cooling to from 72.degree. to 101.degree. C.
