Abstract
The present invention uses a wiring scheme for data transmission. The wiring scheme includes designating N−1 telecommunication wires and a common wire to each carry N−1 signals. The wiring scheme further includes designating one telecommunication wire, other than the N−1 telecommunication wires, as a common wire for each of the N−1 wires. In addition, the DC voltage polarities of at least one of the N−1 telecommunication wires may be reversed to reduce the likelihood of overloading the common wire. The wiring scheme may be utilized in the context of many data transmission systems including: POTS, PSTN, DSL, data modems, facsimile modems, and ISDN. The wiring scheme of the present invention may achieve higher data rates for data transmission.
