Frequently Asked Questions
-
What is a Virtual Tributary 1 (payload)?
-
It is a sub-rate container within a SONET/SDH synchronous transport frame used to carry lower-rate signals multiplexed into a higher-rate optical stream.
-
What does IDE (DMA mode 2) refer to?
-
It describes a Parallel ATA data-transfer mode that allows devices to move data directly to system memory with minimal CPU use, improving throughput on legacy PATA/IDE interfaces.
-
Why convert VT1 payload to IDE DMA mode 2?
-
This conversion helps translate data transfer rates from optical networking units to legacy storage interface modes for performance comparison and system diagnostics.
