scope:

This Technical Specification describes: ♣ the system physical structure; ♣ the system control signals, which implement a set of messages using DiSEqC physical layer but not the DiSEqC message structure; ♣ the definition of identified configurations; ♣ the management of the potential collisions in the control signals traffic. Figure 1 illustrates the physical system configuration considered in this Technical Specification. Several satellite signal demodulators can receive signals from any of the input signal banks (Bank 1, Bank 2, ⋅⋅⋅⋅ Bank M, with M ≤ 256) 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, with N ≤ 32). 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.
