Abstract:
A method for transmitting data over a loaded twisted pair network using a differential voltage, frequency offset, OOK transmission, the method comprising:receiving a data signal from a data source device; providing a base frequency carrier; controlling states of the base frequency carrier, the carrier states including an on state and an off state; transmitting the data signal, using the base frequency carrier, to a loaded twisted pair wire via a twisted pair coupler and a coupler relay, the coupler relay transmitting the data signal when power in the loaded twisted pair wire is lost; receiving the transmitted data signal from the loaded twisted pair wire via a twisted pair decoupler and a decoupler relay, the decoupler relay receiving the data signal when the power in the loaded twisted pair wire is lost; and sending the data signal to a data receiving device.
