Hi Yuen,

1000 Base T uses all the 4 pairs in both the directions simultaneously where in 1000 base Tx does that with only 2 pairs used for the two way communication... i.e. one pair for each direction

Cat 5 and advanced models supports 1000 base T.

Cat 6 and above supports 1000 Base Tx.

Refer the below wikipedia for more information.
