What Is This Tool?
This converter transforms data transfer measurements from IDE (UDMA mode 1), a legacy PATA interface mode, to Virtual Tributary 6 (payload), a SONET/SDH sub-container for lower-rate plesiochronous signals. It helps translate older transfer rates into a format suitable for modern optical transport.
How to Use This Tool?
-
Enter the data value measured in IDE (UDMA mode 1) units
-
Select IDE (UDMA mode 1) as the source unit
-
Choose Virtual Tributary 6 (payload) as the target unit
-
Initiate the conversion to see equivalent values in Virtual Tributary 6 payloads
Key Features
-
Converts IDE (UDMA mode 1) transfer rates into Virtual Tributary 6 payload units

Examples
-
1 IDE (UDMA mode 1) equals approximately 33.333 Virtual Tributary 6 (payload)
-
2 IDE (UDMA mode 1) amounts to about 66.666 Virtual Tributary 6 (payload)
Common Use Cases
-
Diagnosing and specifying legacy PATA device transfer modes in vintage computing
-
Benchmarking throughput of older IDE hard drives and optical drives
-
Integrating legacy IDE transfer rates into SONET/SDH optical transport systems
-
Mapping PDH circuits over SONET rings via Virtual Tributary 6 containers

Tips & Best Practices
-
Use this tool primarily for theoretical maximum rate conversions
-
Consider legacy device limitations when using conversion values
-
Employ output data to facilitate integration between older and modern networks
-
Be aware that real-world transfer rates may differ due to hardware and signal factors
Limitations
-
IDE (UDMA mode 1) represents an outdated PATA mode with limited modern relevance
-
Conversion relies on theoretical maximum speeds, excluding real-world overhead
-
Virtual Tributary 6 size is fixed and tailored to specific PDH signals
-
Direct comparisons between raw IDE transfer rates and VT6 payloads are approximate
Frequently Asked Questions
-
What does IDE (UDMA mode 1) represent?
-
It is an Ultra DMA transfer mode for Parallel ATA devices, offering about 25 MB/s maximum raw transfer rate, used mainly in older PATA drives.
-
What is a Virtual Tributary 6 (payload)?
-
VT6 is a standardized SONET/SDH container designed to carry defined lower-rate plesiochronous payloads within larger synchronous transmission frames.
-
Why convert IDE (UDMA mode 1) to Virtual Tributary 6 payload?
-
This conversion helps translate legacy IDE transfer rates into standardized SONET/SDH payload units for efficient integration and multiplexing on modern networks.
Key Terminology
-
IDE (UDMA mode 1)
-
A legacy Ultra DMA transfer mode of the Parallel ATA interface providing about 25 MB/s maximum raw transfer rate, used in older PATA devices.
-
Virtual Tributary 6 (payload)
-
A SONET/SDH virtual tributary container that carries fixed-size lower-rate plesiochronous payloads for multiplexing within synchronous optical frames.
-
SONET/SDH
-
Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) are standards for high-speed optical telecommunications networks.
-
Plesiochronous
-
A timing characteristic where signals run at almost the same rate but are not perfectly synchronized.
