What is IDE (DMA mode 2)?

IDE (DMA mode 2) is a Parallel ATA data-transfer mode that allows devices to move data directly to or from system memory with less CPU usage, improving transfer speeds compared to older PIO modes.

What does Virtual Tributary 1 (payload) represent?

Virtual Tributary 1 (payload) is a standardized sub-rate container within SONET/SDH frames used to carry lower-rate digital signals multiplexed into an optical transport stream.

Why convert between IDE (DMA mode 2) and VT1 payload units?

This conversion helps translate legacy IDE data rates into compatible formats for SONET/SDH networks, aiding in network integration and data stream management.
