Abstract:
1. A method comprising: receiving a first signal from a first lane; determining first equalizer settings of a first transmitter of the first signal based in part on error properties of the first signal using clock and data recovery for the first signal and also based in part on control signals from the first transmitter determined using a first control channel decoder, wherein the first equalizer used by the first transmitter is in compliance with one or more of clauses 72.7.1.10 and 72.7.1.11 of IEEE Std 802.3ap-2007; requesting adjustment of the first equalizer settings using a control channel in compliance with a 10GBASE-KR PMD control function defined in clause 72.6.10 of IEEE Std 802.3ap-2007; receiving a second signal from a second lane; determining second equalizer settings of a second transmitter of the second signal based in part on error properties of the second signal using clock and data recovery for the second signal and also based in part on control signals from the second transmitter determined using a second control channel decoder; transmitting the first equalizer settings to a receiver associated with the first transmitter; transmitting the second equalizer settings to a receiver associated with the second transmitter; requesting to adjust settings applied by the first equalizer of the first transmitter; requesting to adjust settings applied by the second equalizer of the second transmitter; and forming a third signal by combining contents of the received first and second signals, wherein the first equalizer settings are determined independently from the second equalizer settings; the first transmitter transmits independently of the second transmitter; an aggregate transmission rate of signals transmitted over the multiple lanes is approximately a number of lanes times a transmission rate specified in 10GBASE-KR of IEEE 802.3ap (2007) and electrical characteristics of the first and second transmitters are in compliance with clause 72.7.1 of IEEE Std 802.3ap-2007.
