Abstract
A network station receives a principal signal and data. When the principal signal is present or contains information it is transmitted to a receiving station through a communications channel. When the principal signal is absent or does not have a significant information content, the network station transmits the data through the same communications channel in a format such that the data is received and output by a further receiving station.
