Frequently Asked Questions
-
What is IDE (UDMA mode 4)?
-
IDE (UDMA mode 4), also called Ultra DMA/66, is a Parallel ATA transfer mode used in legacy computers to transfer data up to approximately 66.7 megabytes per second over an 80-conductor cable.
-
What does Virtual Tributary 1 signal mean?
-
Virtual Tributary 1 is a logical sub-channel in SONET/SDH that carries lower-rate signals within a higher-rate synchronous frame, allowing independent grooming and switching.
-
Why convert IDE (UDMA mode 4) to Virtual Tributary 1?
-
This conversion helps translate legacy data transfer rates into telecommunications channel units for applications like network grooming and bandwidth aggregation.
