摘要：A method of operating repeaters (12, 14) or other hub devices in a local areanetwork (5), such as one conforming to Ethernet protocol, in which there are a plurality ofrepeater interfaces (22, 24) of respectively different data rates for communicating with alink partner (50) on a network medium (52) comprises determining the data rate ofoperation of the link partner (50), and based on that data rate, automatically steeringdata between the network medium (52) and a selected one of the repeaters (12, 14). In apreferred embodiment, a network transceiver (16) comprises one or more physical layerdevices (PHY), and a plurality of shared data busses (48) corresponding, respectively, tothe speeds of operation of the repeaters, for interconnecting the repeaters (12, 14) andone or more of the physical layer devices (16; 70). A multiplexer (60) interconnects eachof the one or more physical layer devices to a selected one of the plurality of busses(48), and an auto-negotiation unit (54) controls the multiplexer (60) to interconnect thephysical layer devices to corresponding busses selected depending on the operatingspeed of the link partner.
