Patent ID: 8396137

Claim:
A method for transmitting data, the method comprising: generating a data signal containing input data according to a signaling protocol; simultaneously transmitting the data signal through a first transmitter configured to transmit the data signal over unshielded twisted-pair wire at a first frequency and a second transmitter configured to transmit the data signal over the unshielded twisted-pair wire at a second frequency, the second frequency being higher than the first frequency; receiving the data signal at a first receiver corresponding to the first transmitter and a second receiver corresponding to the second transmitter; validating the data contained in the data signal received at the first receiver; upon determining that the data contained in the data signal received at the first receiver is valid, extracting output data from the data signal received at the first receiver; upon determining that the data contained in the data signal received at the first receiver is not valid, validating the data contained in the data signal received at the second receiver; and upon determining that the data contained in the data signal received at the second receiver is valid, extracting the output data from the data signal received at the second receiver.
