Abstract
Out-of-band data communication of diagnostic and/or configuration data is performed using transceivers in a data or communication network. A light beam or other carrier is modulated with high-speed data and out-of-band diagnostic and/or configuration data to create a double modulated data signal. A physical layer signal is created that includes modulations of the double modulated signal. The physical layer signal is transmitted onto a physical link. The diagnostic and/or configuration data can be transmitted in the out-of-band signal without substantially reducing or otherwise interfering with the transmission rate of the high-speed data.
