What Is This Tool?
This converter allows users to translate values from Virtual Tributary 2 (payload), a SONET/SDH virtual tributary container for 2.048 Mb/s channels, into IDE (UDMA mode 3), an Ultra DMA transfer mode for Parallel ATA interfaces. It helps relate telecommunications channel bandwidths with legacy computer storage transfer modes.
How to Use This Tool?
-
Enter the amount in Virtual Tributary 2 (payload) units.
-
Choose the desired output unit as IDE (UDMA mode 3).
-
Click convert to see the equivalent value.
-
Use the output to compare data transfer capabilities across legacy systems.
Key Features
-
Converts between Virtual Tributary 2 payload and IDE (UDMA mode 3) units
-
Supports comparisons between network data channels and legacy PATA/IDE drive rates
-
Utilizes a fixed conversion rate for consistent results
-
Browser-based and easy to use without installation
Examples
-
10 Virtual Tributary 2 (payload) converts to 0.0512 IDE (UDMA mode 3).
-
100 Virtual Tributary 2 (payload) converts to 0.512 IDE (UDMA mode 3).
Common Use Cases
-
Assessing bandwidth equivalence between SONET/SDH TDM channels and PATA/IDE drives.
-
Supporting legacy telecommunications and computer hardware integration efforts.
-
Interpreting drive transfer modes in BIOS or firmware for older systems.
Tips & Best Practices
-
Verify the context of use given the different underlying technologies.
-
Use the conversion for approximate throughput comparisons only.
-
Keep in mind that actual transfer rates may differ due to hardware overhead.
-
Consult system documentation for compatible transfer modes on legacy devices.
Limitations
-
Conversion compares fundamentally distinct technologies: network payload versus interface transfer mode.
-
IDE (UDMA mode 3) is a legacy interface with nominal maximum speeds that may vary in practice.
-
Virtual Tributary 2 payloads include synchronous transport overhead not reflected in raw rate comparisons.
Frequently Asked Questions
-
What does Virtual Tributary 2 (payload) represent?
-
It is a SONET/SDH virtual tributary sized to carry a 2.048 Mb/s PDH/E1 channel, used for transporting TDM signals in synchronous optical networks.
-
What is IDE (UDMA mode 3)?
-
IDE (UDMA mode 3) is an Ultra DMA transfer mode for Parallel ATA interfaces that allows about 44.4 MB/s data transfers with minimal CPU use.
-
Why convert between these two units?
-
To compare or relate legacy telecommunications channel bandwidths with computer storage transfer modes in integration or analysis tasks.
Key Terminology
