scope:

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 Specifications Version 4.2, February 25, 1998 ;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 signalbanks of the LNB or the switch; the signals selected by the demodulators (or receivers) are transported via a single cable to these demodulators (receiver 1, receiver 2, receiver N). To achieve these single cable distributions, the Single Cable Interface (SCIF) (likely embedded in a LNB or a Switch) features some specific functions and characteristics.
