Abstract:
In a data transmission system comprising means for transmitting a clock signal, a data signal, and a frame synchronization signal through a transmission medium, and means for receiving the clock, data, and frame synchronization signals from the transmission medium, an apparatus for synchronizing the clock, data, and frame synchronization signals comprising:means for encoding the clock, data, and frame synchronization signals into a single bit stream formatted as a :bi-phase mark signal, the means for encoding comprising means for generating a plurality of timing signals; and means, responsive in part to the means for generating the plurality of timing signals, for encoding the frame synchronization signal as a protocol violation of the bi-phase mark signal; and means for decoding the bi-phase mark signal having the protocol violation therein and for recovering the clock, data, frame synchronization signals.
