Abstract
Various techniques are provided to facilitate the identification of devices, such as high performance data communication devices, when such devices are connected over a data communication bus. In one example, high performance devices may identify each other by providing frequency modulated signal bursts which fall within a range of frequencies associated with a data communication standard. Similarly-implemented high performance devices may recognize patterns encoded in the frequency modulations of the signal bursts and thereby identify each other. Advantageously, while providing the frequency modulated signal bursts, the high performance devices may remain compliant with the data communication standard to facilitate communication with other types of devices which may expect to receive communications in accordance with the data communication standard.
