Abstract
A method of transmitting information over POTS wiring includes transmitting a first delimiter signal, in the form of a multi-cycle waveform having a frequency of approximately 7.5 MHz, over the POTS wiring. A second delimiter signal, also comprising a multi-cycle waveform, is then later propagated over the POTS wiring. The time duration between the respective propagations of the first and second delimiter signals defines a symbol, which encodes information. The time duration is also such that reflections on the carrier medium resulting from the propagation of the first delimiter signal decay to a predetermined level prior to propagation of the second delimiter signal.
