  • Communication system having designated transmission lines
    Patent number: 4463350
    Abstract: A communication system is provided in which a plurality of communication devices communicate with one another over a plurality of transmission lines. One of the communication devices operates as a master station, while the remaining devices are slave stations. The master station periodically transmits transmission line specifying signals which specify or identify which of the transmission lines is to be used by the devices for communicating with one another. The master station, when operating normally, will periodically change the transmission line in use so that each of the plurality of transmission lines is used in turn and for substantially similar periods of time. At such time as any one of the slave stations detects a problem in a transmission line in use, that slave station will transmit an abnormality detected signal.
