Patent ID: 8644371

Claim:
A transceiver comprising: a first transmitter; a first receiver; a second transmitter; and a second receiver, wherein: the first transmitter comprises an equalizer, wherein the equalizer is in compliance with one or more of clauses 72.7.1.10 and 72.7.1.11 of IEEE Std 802.3ap-2007 and wherein electrical characteristics of the first transmitter are in compliance with clause 72.7.1 of IEEE Std 802.3ap-2007; the first receiver comprises: clock and data recovery logic to determine error properties of a signal received from a third transmitter; control channel decoder to decode control signals received from the third transmitter; remote transmit adaptation engine to determine equalizer settings of an equalizer of the third transmitter based in part on the error properties and the control signals; and a transmit control logic to request to adjust settings applied by the equalizer of the first transmitter, the settings received from the third transmitter; the second transmitter comprises an equalizer, wherein the equalizer is in compliance with one or more of clauses 72.7.1.10 and 72.7.1.11 of IEEE Std 802.3ap-2007 and wherein electrical characteristics of the second transmitter are in compliance with clause 72.7.1 of IEEE Std 802.3ap-2007; the second receiver comprises: clock and data recovery logic to determine error properties of a signal received from a fourth transmitter; control channel decoder to decode control signals received from the fourth transmitter; remote transmit adaptation engine to determine equalizer settings of an equalizer of the fourth transmitter based in part on the error properties and the control signals; and a transmit control logic to request to adjust settings applied by the equalizer of the second transmitter, the settings received from the fourth transmitter; and the remote transmit adaptation engine of the first receiver and the remote transmit adaptation engine of the second receiver are to independently determine equalizer settings of the third and fourth transmitters.
