Method and apparatus for transmitting and receiving a symbol over pots wiring using a multi-cycle waveform
First Claim
1. A method of transmitting information over a carrier medium within a computer network, the method including:
- selecting a time symbol from a group of time symbols, each time symbol within the group of time symbols representing predetermined information;
propagating a first delimiter signal over the carrier medium at a first time; and
propagating a second delimiter signal over the carrier medium at a second time, the time duration between the propagation of the first and second delimiter signals defining the selected time symbol, and the first and second delimiter signals each comprising a multi-cycle waveform having a frequency of greater than 1.1 MHz.

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.

12. Apparatus for transmitting information over a carrier medium within a computer network, the apparatus including:
-
an output to couple the apparatus to the carrier medium; and
an encoder to select a time symbol from a group of time symbols, each time symbol within the group of time symbols representing predetermined information;
a transmitter, coupled to the encoder, to propagate first and second delimiter signals at first and second times, the time duration between the propagation of the first and second delimiter signals defining the selected time symbol, and to construct each of the first and second delimiter signals as a multi-cycle waveform having a frequency of greater than 1.1 MHz. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
