A networking device includes a legacy preamble injector that inserts a legacy preamble based on an indication that a legacy device is coupled to a common network. The legacy preamble injector inserts the legacy preamble if a legacy device is a target device for communication from a network appliance

A networking device includes a legacy preamble injector that inserts a legacy preamble based on an indication that a legacy device is coupled to a common network. The legacy preamble injector inserts the legacy preamble if a legacy device is a target device for communication from a network appliance. Alternately, a device may be adapted to output a payload portion at a native rate, for example, if a legacy device is not a target. A Home Phone Line Network Alliance (HomePNA) system includes a telephone line network and a plurality of devices couple to the telephone line network. The plurality of devices may include at least one V2.x device and at least one V1.x device. The at least one V2.x device is adapted to recognize a presence on the telephone line network of at least one V1.x device, and to modify a transmission frame format based on this recognition.

A device connectable to a common communications bus having a plurality of signal lines for conducting a first set of signals, including first control signal lines for conducting control signals of the first set of signals, the device including: first means for transmitting or receiving the first set of signals on the signal lines, including individual signals having at least one of a first meaning and a first form; and second means for transmitting or receiving a second set of signals on the signal lines, including the individual signals having at least one of a second meaning and a second form different from the first meaning and the first form, respectively, including transmitting and receiving control signals of the second set of signals, on the signal lines other than the first control signal lines; whereby the device is able to communicate on the bus with devices that communicate exclusively via the first set of signals as well as with devices that communicate via the second set of signals. 13. The device of claim 12 in combination with: the communications bus; at least one device that communicates via the first set of signals; and at least one device that communicates via the second set of signals. 14. A method of communicating between three devices connected by a communications bus common to the three devices and having a plurality of signal lines including first critical control signal lines, comprising: a first one and a second one of the three devices communicating with each other by transmitting and receiving exclusively signals of a first set of signals on the signal lines of the bus, including individual signals having at least one of a first meaning and a first form, including transmitting and receiving critical control signals of the first set of signals on the first critical control signal lines; and the first one and a third one of the three devices communicating with each other by transmitting and receiving signals of a second set of signals on the signal lines of the bus, including the individual signals having at least one of a second meaning and a second form different from the first meaning and the first form, respectively, including transmitting and receiving control signals of the second set of signals on signal lines other than the first critical control signal lines.
