Abstract
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.
