Claim 23:
24. A method for communicating in a network that includes a first network device coupled to a second network device via a first cable having a first maximum bandwidth rating, wherein the second network device also communicates via one or more second cablces separate from the first cable, the one or more second cables having a second maximum bandwidth rating, the method comprising:
receiving, at a transceiver of the first network device, a first Ethernet signal via the first cable, the first Ethernet signal having been transmitted by the second network device at a first baud rate; and
concurrently with receiving the first Ethernet signal via the first cable, transmitting, by the transceiver, a second Ethernet signal via the first cable at a second baud rate, wherein the second network device transmits, concurrently with the transmitter transmitting the second Ethernet signal, one or more respective third Ethernet signals via the one or more second cables at a third baud rate that corresponds to a first minimum required bandwidth that exceeds the second maximum bandwidth rating of the one or more second cables, wherein transmission of the second Ethernet signal in the first cable causes first crosstalk into the one or more second cables that are separate from the first cable, wherein transmission of the one or more respective third Ethernet signals in the one or more second cables causes second crosstalk into the first cable, wherein the second band rate of the second Ethernet signal is selected to i) correspond to a second minimum required bandwidth that is no more than the first maximum bandwidth rating of the first cable, ii) be lower than the first baud rate to reduce the first crosstalk, caused by transmission of the second Ethernet signal in the first cable, into the one or more second cables that are separate from the first cable, iii) reduce power of the first crosstalk into the one or more second cables caused by the second Ethernet signal in the first cable, and iv) be lower than the third baud rate to locate the second Ethernet signal in a frequency range in which a maximum power level of the second crosstalk in the first cable is lower than power levels of the second crosstalk at frequencies above the frequency range to facilitate mitigation of the second crosstalk in the second Ethernet signal.
