Patent ID: 7116678

Claim:
An electronic communications network device, comprising: a receive port terminating a receive path and said receive port providing connections to at least two pairs of receive cables; a transmit port terminating a transmit path and said transmit port providing connections to at least two pairs of transmit cables; a scrambler circuit coupled to said transmit port; a 4B to 5B coder coupled to said scrambler circuit; a regulated mark inversion (RMI) coder coupled to said 4B to 5B coder; wherein data transmissions over a communications network are split by data network transmitters amongst two pair of a set of four pair of cables, wherein said data transmission split reduces bandwidth load and signal attenuation per cable pair and enables an increase in minimum transmit amplitude, wherein a carrier is sent during actual transmit and not sent during idle, and further wherein a transmitted signal is passed in sequence through said scrambler circuit, said 4B to 5B coder, and said RMI coder.
