Figure 7: Example of one-Switch coupling
The coupling between two networks is effected by the main line (thick blue
line), which is connected to the partner coupling port. If the main line fails, the
redundant line (thick blue dotted line), which is connected to the coupling
port, takes over coupling the two networks. The coupling is effected by one
Switch.
