Satellite signal distribution over a single coaxial cable - Second generation
 N EN 50607

Annotation

This European Standard 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 standard.

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.
