What Is This Tool?
This converter allows users to translate data transfer values from Virtual Tributary 2 (payload), a SONET/SDH virtual tributary sized for 2.048 Mb/s PDH/E1 channels, into IDE (UDMA mode 0), a Parallel ATA interface speed standard. It aids in comparing and analyzing data rates between legacy optical transport and disk interface technologies.
How to Use This Tool?
-
Enter the number of Virtual Tributary 2 (payload) units to convert
-
Select Virtual Tributary 2 (payload) as the input unit
-
Choose IDE (UDMA mode 0) as the output unit

Key Features
-
Converts from Virtual Tributary 2 (payload) units to IDE (UDMA mode 0) data transfer rates
-
Supports legacy telecom and storage interface measurements
-
Provides quick ratio-based conversion using standardized formula
-
Browser-based tool requiring no installation or special software
Examples
-
1 Virtual Tributary 2 (payload) equals approximately 0.0154 IDE (UDMA mode 0)
-
10 Virtual Tributary 2 (payload) equals approximately 0.1542 IDE (UDMA mode 0)
Common Use Cases
-
Transporting and evaluating E1 voice or data circuits over SONET/SDH networks
-
Diagnosing throughput on legacy PATA/IDE hard drives using IDE (UDMA mode 0) speeds
-
Planning system migrations by comparing legacy optical and disk interface transfer rates
-
Troubleshooting DMA timing and compatibility issues in older hardware environments
Tips & Best Practices
-
Understand that this conversion compares different data transfer technologies with inherent differences
-
Use the tool for diagnostic and planning purposes rather than real-time throughput comparisons
-
Consult device documentation for compatibility when migrating from PATA/IDE to modern interfaces
-
Validate conversions with multiple examples to ensure expected outcomes
Limitations
-
Conversion rates are nominal and not exact real-time throughput due to protocol overhead
-
Different data transfer mechanisms limit direct comparability between units
-
IDE (UDMA mode 0) speeds are constrained by legacy hardware and interface obsolescence
Frequently Asked Questions
-
What does Virtual Tributary 2 (payload) represent?
-
It is a SONET/SDH virtual tributary container used to transport a 2.048 Mb/s PDH/E1 channel within higher-rate optical frames for legacy TDM services.
-
What is IDE (UDMA mode 0)?
-
IDE (UDMA mode 0) is an Ultra DMA transfer mode for Parallel ATA devices defining interface timing and a maximum raw data transfer rate around 16.7 MB/s.
-
Why convert between these units?
-
Users often compare or translate data transfer rates between legacy SONET/SDH optical systems and PATA/IDE device speeds for diagnostics, compatibility checks, and migration planning.
Key Terminology
-
Virtual Tributary 2 (payload)
-
A SONET/SDH virtual tributary container sized to carry a 2.048 Mb/s PDH/E1 channel for multiplexing lower-rate TDM signals into higher-rate optical frames.
-
IDE (UDMA mode 0)
-
An Ultra DMA transfer mode 0 used in Parallel ATA devices defining interface timings and a nominal maximum transfer rate near 16.7 MB/s.
-
Data Transfer Rate
-
The speed at which data is moved from one device or medium to another, often measured in megabits or megabytes per second.
