What is IDE (DMA mode 2)?

IDE (DMA mode 2) is a legacy Parallel ATA data-transfer mode allowing direct memory access with minimal CPU use, improving throughput compared to older PIO modes.

What does the T4 (signal) represent?

T4 (signal) is a high-order trunk line in the North American T-carrier system, carrying multiplexed channels at about 274 Mbps, used historically in telecom backbones.

Can I interchangeably use IDE (DMA mode 2) and T4 (signal)?

No, these units represent different technologies and are only comparable in terms of data transfer rate but not interchangeable for operational use.
