  • Arrangement for transmitting digital data and synchronizing information
    Patent number: 4054754
    Abstract: A high capacity time-division switching system is disclosed which includes a digital data transmission system for transmitting both digital data words and synchronizing information. The predetermined bit positions of each data word, which bit positions are to convey data only, are encoded and transmitted as a combination of the true and complement representation of those digits. The remaining bit positions, which are used to convey both data and synchronizing information, are encoded and transmitted as true representations only. A digital data receiver responds to the data so encoded by extracting synchronizing information based on the violation of the predominately true and complement coding format.
