  • Data compression-decompression method and apparatus for synchronous terminal means
    Patent number: 5483556
    Abstract: A first frame produced by a first terminal is compressed after suppressing certain of the data fields forming it, then transmitted via a safe link through a transmission network into a second frame. This second frame received by a second terminal via the safe link is unpacked-from the fields relating to this safe link, whereupon the remainder of the frame is decompressed. The data fields suppressed for transmission by the first terminal are restored, either by calculation (for example, in the case of a frame checking sequence), or by insertion of a given word (for example, for each flag between frames). This data compressing and decompressing method is carried out in a data circuit-terminating equipment for a synchronous terminal.
