Abstract:
1. A system for providing data communication over a channel having a plurality of links, the system comprising: a first transceiver module including: a second transceiver module, coupled to the first transceiver module via at one of the plurality of links, the second transceiver module including: a receiver module to receive the data transmitted by the transmitter module of the first transceiver module, wherein the transmitter module of the first transceiver module and the receiver module of the second transceiver communicate using an n-level pulse amplitude modulated (PAM) communication technique; and a first back channel that transmits back channel data, from the second transceiver module to the first transceiver module, without reducing channel communications capacity for non-back channel data, wherein the back channel data is representative of the set of coefficients for the adjustable transmit equalizer of the first transceiver module.
