Abstract:
A method for bidirectional signal transmission, the method which comprises:providing a transmission/termination circuit configuration at a first location and a further transmission/tertflination circuit configuration at a second location, the transmission/termination circuit configurations being operatively connected via a common transmission line, each of the transmission/termination circuit configurations having a plurality of elements integrated in a single combined circuit configuration for switching together selectively between two functions, the functions being a transmission operating mode and a reception/termination operating mode; supplying a respective operating mode control signal to the transmission/termination circuit configurations in order to switch the impedance elements between the transmission operating mode and the reception/termination operating mode; and switching the elements of the transmission/termination circuit configurations depending on the respective operating mode control signal supplied thereto such that each of the transmission/termination circuit configurations is selectively switched to the transmission operating mode for transmitting an electrical signal via the common transmission line and to the reception/termination operating mode for forming a line termination such that an electrical signal received via the common transmission line is matched with the line termination.
