ABSTRACT:
An in-line data communication system includes a bidirectional communication cable for connecting at least two terminal stations. A signal level compensation circuit is connected to the bidirectional communication cable for compensating for signal attenuation in the bidirectional communication cable. The signal level compensation circuit includes first and second amplifying circuits connected to each other in a parallel fashion. When a data signal is transmitted in one direction in the bidirectional communication cable, the first amplifying circuit is enabled and the second amplifying circuit is disabled. When the data signal is transmitted in the opposing direction, the first amplifying circuit is disabled and the second amplifying circuit is enabled.
