1000 Mbps Gigabit Ethernet specification using UTP wiring (Category 5e or better, with all four pairs in the cable carrying information bi-directionally). Like the 10BASE-T and 100BASE-TX technologies on which it is based, 1000BASE-T sends link pulses over the network segment when no traffic is present. However, these link pulses contain more information than those used in 10BASE-T and 100BASE-TX. The 100BASE-TX specification is based on the IEEE 802.3ab Gigabit Ethernet standard.
