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.
