What Is This Tool?
This tool facilitates the conversion of data transfer rates from IDE (DMA mode 1), a legacy direct memory access transfer mode for IDE/ATA devices, to Virtual Tributary 6 (VT6), a SONET/SDH payload container for lower-rate data transport within optical networks.
How to Use This Tool?
-
Enter the value measured in IDE (DMA mode 1) units you want to convert
-
Select IDE (DMA mode 1) as the input unit and Virtual Tributary 6 (payload) as the output unit

Examples
-
1 IDE (DMA mode 1) equals approximately 17.733 Virtual Tributary 6 (payload)
-
3 IDE (DMA mode 1) units convert to about 53.2 Virtual Tributary 6 (payload)
-
These examples illustrate conversion from legacy IDE data rates to SONET/SDH payload containers
Common Use Cases
-
Translating data transfer rates from legacy IDE DMA modes to SONET/SDH payload units
-
Mapping and transporting PDH circuits over SONET networks using VT6 containers
-
Configuring legacy systems where IDE DMA settings affect performance
-
Aggregating low-rate services into higher-rate optical frames for efficient network transport

Tips & Best Practices
-
Ensure you understand the fundamental difference between storage interface rates and optical payload units before converting
-
Use the tool primarily for planning and interfacing legacy devices with modern SONET/SDH systems
-
Check the IDE mode 1 settings and SONET payload configurations for compatibility in your specific use case
-
Consider variability in real-world transfer speeds when applying conversion results
-
Leverage provided examples to verify conversions and gain confidence with the tool
Limitations
-
Conversion assumes fixed transfer rates which may differ from actual device performance
-
IDE (DMA mode 1) and Virtual Tributary 6 payload units represent distinct technologies and are not physically interchangeable
-
This tool is intended primarily for analytical, planning, and integration contexts rather than real-time data transfer
-
Variability in IDE bus speeds and SONET configurations can affect the practical accuracy of conversions
Frequently Asked Questions
-
What does IDE (DMA mode 1) stand for?
-
IDE (DMA mode 1) is a direct memory access transfer mode used by legacy IDE/ATA devices to move data with minimal CPU involvement following specific timing and protocol rules.
-
What is Virtual Tributary 6 used for?
-
Virtual Tributary 6 is a SONET/SDH virtual container designed to carry lower-rate plesiochronous payloads within larger synchronous optical transport frames.
-
Can I use this tool for real-time data transfer between IDE and SONET devices?
-
No, this conversion tool is meant for planning and interfacing purposes and does not facilitate direct physical data compatibility between the different technologies.
Key Terminology
-
IDE (DMA mode 1)
-
A legacy direct memory access transfer mode under the IDE/ATA specification enabling moderate-speed data transfer to or from system memory with reduced CPU usage.
-
Virtual Tributary 6 (VT6)
-
A SONET/SDH defined virtual container that carries lower-rate plesiochronous payloads within a synchronous optical networking frame.
-
Data Transfer Rate Conversion
-
The process of translating data measurements from one unit or technology standard to another to enable interoperability or system integration.
