适用范围：This European Standard describes:– the system physical structure;– the system control signals, which implement an extension of the DiSEqC set of commandsdescribed in the DiSEqC bus functional specification;– the definition of identified configurations;– management of the potential collisions in the control signals traffic.Figure 1 illustrates the physical system configuration considered in this European Standard.Several satellite signal demodulators can receive signals from any of the input signal banks of the LNBor the switch; the signals selected by the demodulators (or receivers) are transported via a singlecable to these demodulators (receiver 1, receiver 2, receiver N).To achieve these single cable distributions, the Single Cable Interface (SCIF) (likely embedded in aLNB or a Switch) features some specific functions and characteristics.Figure 1 – General architecture of the single cable distribution
