EN 50494:2007

Satellite signal distribution over a single coaxial cable in single dwelling installations

This European Standard describes: – the system physical structure; – the system control signals, which implement an extension of the DiSEqC set of commands described in the DiSEqC bus functional specification; – the definition of identified configurations; – management of the potential collisions in the control signals traffic.

Signalverteilung von Satellitensignalen über ein einziges koaxiales Kabelverteilnetz

Diese Europäische Norm legt fest: – die physikalische Systemstruktur; – die System-Steuersignale, die eine Erweiterung des Sets der DiSEqC-Befehle darstellen, beschrieben in der DiSEqC Bus Functional Specification; – die Definition festgelegter Konfigurationen; – das Management möglicher Kollisionen im Datenverkehr der Steuersignale.
