    摘要: An encoding and decoding mechanism for communicating digital data where the binary states are represented by a duration of time between transitions of a signal. For instance, the time between zero crossings of a signal are used to represent binary states. These times can be selected so as to avoid ambiguities between the binary state being detected even where the transmission medium is irregular. A typical application is the creation of a LAN in a home using twisted pair telephone lines. The LAN can be made to be transparent and independent of telephone service received over lines shared with the LAN.

    摘要: A LAN which uses flat telephone cable having at least four conductors. The inner conductors are joined together and the outer conductors are joined together at each node thereby making reversals of the inner and outer conductors, which may occur at connectors, impossible. Each node uses two baluns to provide an unbalanced zone between the baluns for connecting to the DTE.
