<p>To provide a method of operating a shielded connection where signals are exchanged between two nodes (1) on a communications network over a connecting line (5a, 5b) and the connecting line (5a, 5b) has a shield (3), by which method can be established that the shield (3) is in a proper state, it is proposed that when a signal is transmitted from a first node (1) over the connecting line (5) to a neighboring node a current (Ishield) is drawn into the shield (3) and when operation is taking place in other ways the shield (3) is set to a bias voltage (UBias). A suitably arranged communications network is also specified.</p> |
