Ring/Network Coupling
The coupling between two networks is performed by the main line (solid blue
line) in the normal mode of operation, which is connected to the partner
coupling port. If the main line becomes inoperable, the redundant line
(dashed blue line), which is connected to the coupling port, takes over the
ring/network coupling. The coupling switch-over is performed by one Switch.
