摘要： A communications system comprises a physical layer device (PLD) including a PLD send interface which, in turn, includes PLD parallel information outputs and at least one PLD control output. The system also includes a logical link device (LLD) which comprises an LLD receive interface which, in turn, includes LLD parallel information inputs and at least one LLD control input. First parallel communications channels connect the PLD information outputs to respective LLD information inputs, and at least one second communications channel connects the at least one PLD control output to the at least one LLD control input so that control signals are sent from the PLD to the LLD out-of-band from information signals. Accordingly, control speed is enhanced, and information throughput efficiency is not compromised. The PLD may further include a PLD receive interface including PLD parallel information inputs and at least one PLD control input, and the LLD may further comprise an LLD send interface including LLD parallel information outputs and at least one LLD control output. In accordance with this aspect of the invention, the PLD and LLD are operable in a push-push configuration. Another advantageous feature of the invention is that the interfaces may be symmetric.

摘要： A communications system includes first and second devices connected by parallel communications channels. The first device preferably comprises a string-based framing coder for determining and appending a string-based framing code to each information symbol string of information symbol strings to be transmitted in parallel over respective parallel communications channels. Each string-based framing code is preferably based upon at least some of the information symbols in the respective information symbol string. In addition, the second device preferably includes a deskewer for aligning received parallel information symbol strings based upon the string-based framing codes. In other words, the string-based framing codes and their use to align received information symbol strings permit the information symbol to be transmitted at high rates and over relatively long distances and thereby be subject skew. The information symbols may be binary bits. The string-based coder may comprise a cyclic redundancy checking (CRC) coder for determining and appending CRC codes to respective information bit strings. Thus, the deskewer may comprise a CRC framer for framing the information bit strings based upon the CRC codes.

摘要： A communication device comprises a signal combiner, first storage elements, second storage elements and a controller. The signal combiner is configured to combine overhead information with additional information in forming a frame of a signal. The first storage elements are adapted to receive respective portions of a given block of the overhead information to be applied to the signal combiner, and the second storage elements are coupled between respective ones of the first storage elements and respective inputs of the signal combiner. The controller is operative to monitor a count of portions of the frame as the frame is formed by the signal combiner and to control loading of the portions of the given block of the overhead information into the second storage elements from the first storage elements responsive to the monitored count. The disclosed techniques for guaranteed consistent overhead insertion can be implemented in any type of communication system which utilizes overhead insertion in its framing operations.
