The signals for the Ethernet ports are as follows:
Signal Description
MDI[0]+ / MDI[0]- In MDI mode, this is the first pair in 1000Base-T, i.e. the BI_DA+/- pair, and is the
transmit pair in 10Base-T and 100Base-TX.
In MDI crossover mode, this pair acts as the BI_DB+/- pair, and is the receive pair
in 10Base-T and 100Base-TX.
MDI[1]+ / MDI[1]- In MDI mode, this is the second pair in 1000Base-T, i.e. the BI_DB+/- pair, and is
the receive pair in 10Base-T and 100Base-TX.
In MDI crossover mode, this pair acts as the BI_DA+/- pair, and is the transmit pair
in 10Base-T and 100Base-TX.
MDI[2]+ / MDI[2]- In MDI mode, this is the third pair in 1000Base-T, i.e. the BI_DC+/- pair.
In MDI crossover mode, this pair acts as the BI_DD+/- pair.
MDI[3]+ / MDI[3]- In MDI mode, this is the fourth pair in 1000Base-T, i.e. the BI_DD+/- pair.
In MDI crossover mode, this pair acts as the BI_DC+/- pair.
Note : MDI = Media Dependent Interface.
