A method for enhanced error protection using double-cyclic redundancy check (CRC) includes receiving a first packet, by a first physical layer (PHY). The first packet includes a source packet and a first CRC. The method also includes encrypting the first packet having the first CRC to generate an encrypted first packet. The method further includes appending a second CRC to the encrypted first packet to produce a second packet, and transmitting the second packet to a second PHY via a transmission line.

Embodiments of the present disclosure provide an in-band process to inform an external repeater of a desired new configuration or mode of operation. After negotiation of rate and other information during an auto-negotiation routine, a network node sends configuration information to a network element, such as an external network repeater.

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.
