Satellite signal distribution over a single coaxial cable - Second generation

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.
