Abstract
In a fast Ethernet, each station is connected to the hub by four unshielded twisted pairs. A first pair is transmit only for the station and receive only for the hub, a second pair is transmit only for the hub and receive only for the station, and the third and fourth pairs are bidirectional. Both the station and the hub use their transmit only and the bidirectional pairs for data transmission and their receive only pair for collision detection.
