  • Method of encoding data for transmission
    Patent number: 5835036
    Abstract: A method of reducing a number of bits required to transmit a digital signal using a PPP protocol is disclosed. The PPP protocol uses a predetermined byte for signalling. When that byte occurs, the following byte indicates signalling or alternatively, indicates a data byte having a value of the signalling byte. A value in the signalling byte is used to indicate a data byte, and other values are encoded to represent two or more signalling bytes within a predetermined spacing. Due to the look-ahead requirements, a time lag is introduced.
