What does IDE (DMA mode 1) represent?

IDE (DMA mode 1) is a specific direct memory access mode for IDE/ATA devices enabling moderate-speed data transfers with minimal CPU usage.

What is a Virtual Tributary 2 (payload)?

It is a SONET/SDH virtual tributary container designed to carry a 2.048 Mb/s PDH/E1 channel, used to multiplex low-rate signals into higher-rate optical frames.

Can this converter be used for direct device communication?

No, the tool translates data rates but does not address protocol differences; additional steps are required for interoperability.
