What Is This Tool?
This unit converter allows you to translate data transfer measurements from IDE (UDMA mode 1), a legacy PATA interface mode, into Virtual Tributary 2 (payload), a SONET/SDH virtual tributary channel format. It helps bridge legacy disk transfer speeds with modern network transport units.
How to Use This Tool?
-
Enter the value in IDE (UDMA mode 1) units you want to convert
-
Select Virtual Tributary 2 (payload) as the target unit
-
Review the converted amount showing equivalent SONET/SDH payload channels
-
Use the results for network capacity planning or vintage system diagnostics

-
Supports legacy and networking data transfer measurement standards
-
Browser-based and simple to use for quick calculations
-
Provides conversion based on recognized technical standards
Examples
-
1 IDE (UDMA mode 1) equals 97.65625 Virtual Tributary 2 (payload)

Common Use Cases
-
Specifying or diagnosing transfer modes on older PATA hard drives and BIOS settings
-
Mapping legacy disk throughput to SONET/SDH network payload capacities
-
Transporting or provisioning E1 voice and data channels over synchronous optical networks
-
Benchmarking theoretical maximum data rates for vintage computing hardware
-
Troubleshooting compatibility and data errors with UDMA mode settings on vintage PCs
Tips & Best Practices
-
Ensure you understand this tool converts theoretical maximum speeds, actual rates may differ
-
Use when working with legacy PATA devices or SONET/SDH network planning
-
Apply conversion results to support vintage system diagnostics or network transport design
-
Keep in mind Virtual Tributary 2 payload units represent fixed network channel capacities
Limitations
-
Conversion is based on theoretical transfer speeds; real-world performance may vary
-
IDE (UDMA mode 1) pertains to obsolete hardware with limited modern application
-
Virtual Tributary 2 payload sizes are standardized and may not reflect instantaneous throughput
Frequently Asked Questions
-
What is IDE (UDMA mode 1)?
-
IDE (UDMA mode 1) is an Ultra DMA transfer mode for older Parallel ATA interfaces, offering a maximum theoretical transfer rate of about 25 MB/s.
-
What does Virtual Tributary 2 (payload) represent?
-
It is a SONET/SDH virtual tributary designed to carry a 2.048 Mb/s PDH/E1 channel for mapping time-division multiplexed signals into optical networks.
-
Why convert IDE (UDMA mode 1) to Virtual Tributary 2 (payload)?
-
This conversion helps translate legacy disk transfer speeds into equivalent SONET/SDH payload units for network transport and multiplexing purposes.
Key Terminology
-
IDE (UDMA mode 1)
