First example (shown in Figure 6-17): The LPV has found a Gigabit device (1000 Mbps) on Pairs 1, 2 and 3, 6 that is capable of transmitting at 10, 100, and 1000 Mbps at full-duplex.

1000-Mbps devices use all 4 pairs.

Second example (shown in Figure 6-18): The LPV has found a 100-Mbps device on Pairs 3, 6 that is capable of transmitting at 10 and 100 Mbps at half-duplex. Typically, devices that transmit on Pairs 1, 2 are PCs and devices that transmit on 3, 6 are hubs and switches.
