How does 1000BASE-T use the UTP wire pairs to accomplish transmission?
two pairs are used to transmit and two pairs are used to receive one pair is used to transmit, one pair is used to receive, one pair is used for clocking, and one pair is used for error correction * all four pairs are used in parallel by both hosts to transmit and receive simultaneously two pairs of wires are used as in 10BASE-T and 100BASE-TX
