Abstract: Disclosed are various embodiments for in-band management of Ethernet links utilizing a bit-interleaved parity (BIP) block in a transmission frame. According to various embodiments, a bit-interleaved parity error code may be generated for a monitored portion of network data for transmission in a first bit-interleaved parity block. Subsequently, network management data may be encoded in a plurality of bits for transmission in a second bit-interleaved parity block according to a predefined block code, wherein the predefined block code generates the plurality of bits to maintain a DC balance between the bit-interleaved parity error code and the plurality of bits.

Abstract: An apparatus and method is disclosed to compensate for one or more offsets in a communications signal. A communications receiver may carry out an offset adjustment algorithm to compensate for the one or more offsets. An initial search procedure determines one or more signal metric maps for one or more selected offset adjustment corrections from the one or more offset adjustment corrections. The offset adjustment algorithm determines one or more optimal points for one or more selected offset adjustment correction based upon the one or more signal maps. The adaptive offset algorithm adjusts each of the one or more selected offset adjustment corrections to their respective optimal points and/or each of one or more non-selected offset adjustment corrections to a corresponding one of a plurality of possible offset corrections to provide one or more adjusted offset adjustment corrections. A tracking mode procedure optimizes the one or more adjusted offset adjustment corrections.

Abstract: A system, method and apparatus for multi-lane auto-negotiation over reduced-lane media. Auto-negotiation over an M-lane communication interface can be coordinated with the auto-negotiation over an N-lane communication interface, wherein M>N. A recursive-type auto-negotiation process would begin with the M-lane communication interface and be prevented from completing until the auto-negotiation process over the N-lane communication interface completes.
