Which pins in an RJ-45 connector are used to transmit data when used on 100baseT Ethernet network?

In a 100BASE-T Ethernet network, data transmission occurs over pins 1 and 2 for transmitting (Tx) and pins 3 and 6 for receiving (Rx). Specifically, pin 1 carries the transmit data (Tx+) and pin 2 carries the transmit data (Tx-), while pin 3 carries the receive data (Rx+) and pin 6 carries the receive data (Rx-). This configuration allows for full-duplex communication, enabling simultaneous transmission and reception of data.
