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.

Enhanced error protection of payload using double CRC

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.
