A technique used in 100Base-TX Ethernet to reduce the signaling rate and thereby lower the carrier frequency in consideration of attenuation issues over twisted pair cable.The line coding technique used in 100Base-TX is 4B/5B, which increases the signaling rate to 125 Mbps in support of a datastream of 100 Mbps. MLT-3 is a ternary approach that cycles through three signal levels in the pattern +V, 0V,
