What Is This Tool?
This converter transforms data transfer values from Virtual Tributary 1 (signal), a sub-rate digital signal used in SONET/SDH transport networks, into IDE (UDMA mode 3), a transfer mode used in legacy PATA/IDE storage devices. It helps relate network bandwidth units with storage device throughput.
How to Use This Tool?
-
Enter the value in Virtual Tributary 1 (signal) units
-
Select Virtual Tributary 1 (signal) as the input unit
-
Choose IDE (UDMA mode 3) as the output unit
-
Click the convert button to get the equivalent IDE (UDMA mode 3) value
-
Use the conversion results to assess data transfer or throughput compatibility
Key Features
-
Supports conversion from Virtual Tributary 1 (signal) to IDE (UDMA mode 3)
-
Browser-based and easy to use
-
Facilitates comparison of network and storage transfer rates
-
Provides conversions based on a precise theoretical conversion rate
-

Examples
-
1 Virtual Tributary 1 (signal) = 0.00432 IDE (UDMA mode 3)
-
10 Virtual Tributary 1 (signals) = 0.0432 IDE (UDMA mode 3)
Common Use Cases
-
Comparing SONET/SDH sub-rate channel throughput with legacy PATA/IDE storage transfer rates
-
Network bandwidth planning in telecommunications environments
-
Configuring or evaluating drive transfer modes in older PCs
-
Interpreting benchmark and compatibility results for PATA/IDE devices
-
Assessing system performance when relating network signals to storage interfaces
Tips & Best Practices
-
Ensure you understand the theoretical nature of the conversion rates used
-
Use this tool to complement, not replace, detailed technical analysis for system compatibility
-
Verify unit selections carefully before converting
-
Apply results as a guide for planning or troubleshooting rather than exact performance figures
Limitations
-
Conversion values reflect theoretical maximum transfer rates only
-
Does not factor in protocol overhead or real-world performance variability
-
Comparison crosses different data transfer mechanisms between network and storage
-
Not suitable for precise performance prediction in operational environments
Frequently Asked Questions
-
What does Virtual Tributary 1 (signal) represent?
-
It is a logical sub-channel in SONET/SDH networks that carries lower-rate plesiochronous digital signals within a higher-rate synchronous frame.
-
What is IDE (UDMA mode 3)?
-
IDE (UDMA mode 3) is a legacy Ultra DMA transfer mode for PATA/IDE interfaces, offering about 44.4 MB/s maximum raw transfer rate with minimal CPU involvement.
-
Why would I convert between these two units?
-
To compare throughput of SONET/SDH sub-rate channels with legacy PATA/IDE storage device rates for system compatibility or performance assessment.
