This European Standard describes:<\/p>\n
the system physical structure;<\/p>\n<\/li>\n
the system control signals, which implement a set of messages using DiSEqC physical layer but not the DiSEqC message structure;<\/p>\n<\/li>\n
the definition of identified configurations;<\/p>\n<\/li>\n
the management of the potential collisions in the control signals traffic.<\/p>\n<\/li>\n<\/ul>\n
Figure 1<\/span> illustrates the physical system configuration considered in this standard.<\/p>\n Several satellite signal demodulators can receive signals from any of the input signal banks (Bank 1, Bank 2, Bank M, with M \u2264 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<\/i> \u2264 32).<\/p>\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.<\/p>\n [Image removed.]<\/i><\/p>\n Satellite signal distribution over a single coaxial cable.
