Carrier in Cable

In a practical installation the one-way paths would be shielded from each other either by placing them in separate cables or by placing them in a single cable divided into two electrical compartments by means of a specially arranged shield. In the setup at Morristown the circuit was necessarily arranged somewhat differently since only one cable was available. Transmission over all loops in this cable went in the same direction, half the loops then being connected in tandem to simulate one direction of transmission through a long circuit and the other half in tandem to simulate the other direction of transmission.
