Abstract: Apparatus, methods, and other embodiments associated with pairing network devices are described. According to one embodiment, a method is performed by a first network device on a data communication network. An identification signal is generated that identifies the first network device. A first transmission frequency is selected that minimizes cross-talk between neighboring wired communication channels of a bundle of wired communication channels. The identification signal is transmitted at the first transmission frequency to a second network device over a first wired communication channel of the bundle of wired communication channels. Pairing the first network device with the second network device is accomplished based on the identification signal. The first transmission frequency is changed to a second transmission frequency that is greater than the first transmission frequency to transmit data to the second network device, subsequent to the pairing, over the first wired communication channel.
