According to the IEEE802.3 local area network standard, in comprehensive wiring system, when adopting CAT5 twisted-pair feeder (UTP) tectonic network, generally adopt two pairs of lines among 4 couples of UTP as data transmission media.For 10Base TEthernet Ethernet, 100 BaseTX, 100 Base VG, adopting sequence number is 1,2, four lines of 3,6, then adopting sequence number for Token Ring network is 3,6, four lines of 4,5, using sequence number at FDDI/TP-PMD, ATM net is 1,2, four lines of 7,8 then use whole four pairs of cables in 100 Base T4 and some 100 Base VG net.As seen, in multi-form network, can't select the dead pair of same numeral to make power line.
