What Is This Tool?
This converter transforms data transfer values from IDE (UDMA mode 3), a legacy Parallel ATA mode with a transfer rate around 44.4 MB/s, into Virtual Tributary 2 (VT2) signals, which are SONET/SDH sub-rate signals carrying a 2.048 Mbps E1 channel.
How to Use This Tool?
-
Enter the value in IDE (UDMA mode 3) units that you want to convert.
-
Select the target unit as Virtual Tributary 2 (signal).
-
Submit the input to get the equivalent number of Virtual Tributary 2 signals based on the conversion rate.
Key Features
-
Converts from IDE (UDMA mode 3) transfer rates to Virtual Tributary 2 (signal) units accurately based on theoretical maximums.
-
Supports understanding and comparison between legacy PATA/IDE storage interfaces and SONET/SDH telecom signals.
-
Browser-based and easy to use with no installation required.
Examples
-
2 IDE (UDMA mode 3) equals 347.2222222222 Virtual Tributary 2 (signal) using the conversion formula.
-
0.5 IDE (UDMA mode 3) corresponds to 86.8055555556 Virtual Tributary 2 (signal) through multiplication.
Common Use Cases
-
Specifying or comparing throughput for older PATA/IDE drives in system documentation or datasheets.
-
Transporting E1 (2.048 Mbps) circuits over SONET backbones in telecom networks.
-
Configuring SONET multiplexers to groom lower-rate PDH channels by understanding equivalent transfer rates.
-
Planning network capacity and provisioning for interworking between legacy storage interfaces and telecom transport systems.
Tips & Best Practices
-
Use this tool when working with legacy hardware or telecom equipment that requires data transfer rate translation.
-
Validate conversion results in the context of system overhead and hardware conditions for practical use.
-
Combine this conversion with documentation review to ensure compatibility when integrating legacy and telecom technologies.
Limitations
-
Conversion is theoretical and reflects maximum raw transfer rates rather than actual throughput.
-
IDE (UDMA mode 3) is a legacy transfer mode and may not reflect modern interface speeds.
-
Virtual Tributary 2 (signal) units apply specifically within SONET/SDH telecom frameworks and may not suit other contexts.
Frequently Asked Questions
-
What does IDE (UDMA mode 3) represent?
-
IDE (UDMA mode 3) is a legacy Ultra DMA transfer mode for Parallel ATA interfaces offering a theoretical maximum raw transfer rate of about 44.4 MB/s.
-
What is Virtual Tributary 2 (signal)?
-
Virtual Tributary 2 (VT2) is a SONET/SDH sub-rate signal carrying a 2.048 Mbps E1 payload inside higher-rate frames for multiplexing lower-rate circuits.
-
Why convert IDE (UDMA mode 3) rates to Virtual Tributary 2 signals?
