摘要： Methods, systems, and apparatuses, including electrical circuitry, are described for auto-negotiation. Active cables, active backplanes, and line cards may include one or more instances of electrical circuitry and/or integrated circuits that intercept advertisements of standard auto-negotiation protocol signaling from an initiating device for establishment of communication links with a receiving device. Auto negotiation information in the intercepted signaling may be translated and encoded into signaling in accordance with the capabilities of the receiving device. Active cables and active backplanes may also include one or more connection components between instances of electrical circuitry and/or integrated circuits to provide high-speed transmission of data packets encapsulating the auto-negotiation information in a format that differs from the standard auto-negotiation protocol.

摘要： Communication device employing binary product coding with selective additional cyclic redundancy check (CRC) therein. Product code encoding (e.g., employing row and column encoding of matrix formatted bits, selectively with interleaving and/or permutation of the bits therein) may be combined with additional error correction code (ECC) or forward error correction (FEC) coding thereby generating coded bits for use in generating a signal to be launched into a communication channel Various ECCs/FECs may be employed including a BCH (Bose and Ray-Chaudhuri, and Hocquenghem) code, a Reed-Solomon (RS) code, an LDPC (Low Density Parity Check) code, etc. The redundancy of such coded signals as generated using the principles herein is in the range of approximately 7%, and hard decision decoding may be performed on such coded signals generated herein. In accordance with decoding such signals, various bit decisions (within certain iterations) may be selectively ignored and/or reverted back to previous bit decisions.
