Annex A (normative) - Implementation rules

Elaborates: - 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; and - the management of the potential collisions in the control signals traffic.

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.
