1) _{The images represent a communication between two participants of the network (see Figure 1). The controller}
of the local area 1 transmits data (T×D₁) to the receiver of the local area 2 (R×D₂). When a single failure of
cases 1 to 7 occurs, the error handling enables communication through appreciated reactions.
