Description
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.
In MDI mode, this is the second pair in 1000Base-T, i.e. the BI_DB+/- pair, and is
the transmit 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.
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.
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.
