What Is This Tool?
This converter facilitates transforming data transfer values from Virtual Tributary 1 (payload), a sub-rate container used in SONET/SDH synchronous transport frames, into IDE (DMA mode 0), the basic direct memory access mode for legacy ATA/IDE devices. It assists users in relating optical network payload transfer rates to older DMA interface speeds.

Frequently Asked Questions
-
What is a Virtual Tributary 1 (payload)?
-
It is a sub-rate container within SONET/SDH synchronous frames used to multiplex lower-rate channels like DS1/T1 into higher-rate optical transport streams.
-
What does IDE (DMA mode 0) represent?
-
IDE (DMA mode 0) is the lowest-speed direct memory access mode for ATA/IDE devices that allows data transfer directly into system memory without CPU-driven I/O.
-
Why convert between Virtual Tributary 1 and IDE DMA modes?
-
Converting helps relate the data transfer rates of SONET/SDH optical payloads to legacy ATA/IDE modes for system integration and performance understanding.
