Table 3. Transceiver Interface

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 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.

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.
