What Is This Tool?
This converter allows you to translate data transfer measures from Virtual Tributary 2 (VT2), a SONET/SDH sub-rate signal carrying an E1 channel, into IDE (UDMA-33), a legacy Parallel ATA transfer mode for older drives. It helps compare different data transfer technologies used in telecommunications and PC hardware.

-
10 Virtual Tributary 2 (signal) equals 0.087272727 IDE (UDMA-33)
Common Use Cases
-
Transporting E1 circuits over SONET backbones using VT2 signals
-
Configuring SONET multiplexers or digital cross-connect systems
-
Benchmarking or reporting throughput of legacy PATA hard drives using IDE (UDMA-33)
-
Troubleshooting or setting BIOS/controller transfer modes on older PCs
-
Comparing legacy PATA performance when upgrading or replacing drives
Tips & Best Practices
-
Understand that these units represent different technologies with unique contexts
-
Use conversion results for planning or benchmarking rather than real-time throughput prediction
-
Ensure compatible hardware and cables when working with IDE (UDMA-33) devices
-
Consider network infrastructure specifics when working with VT2 signals in telecommunications
-
Refer to example conversions to verify your input and expected output
Limitations
-
The conversion compares different data transfer technologies that vary significantly in context
-
IDE (UDMA-33) rates may not reflect actual sustained speeds due to hardware constraints
-
Virtual Tributary 2 signals represent payload rates within SONET/SDH frames, not direct device throughput
Frequently Asked Questions
-
What is Virtual Tributary 2 (VT2)?
-
It is a SONET/SDH sub-rate signal format carrying a 2.048 Mbps payload representing an E1 channel inside a higher-rate multiplexed frame.
-
What does IDE (UDMA-33) stand for?
-
IDE (UDMA-33) is a Parallel ATA transfer mode using direct memory access to achieve a maximum burst rate of about 33.3 MB/s, used in legacy hard and optical drives.
-
Why convert data transfer rates between VT2 and IDE (UDMA-33)?
-
To compare data rates between telecom E1 channel payloads and legacy drive speeds, assisting in network planning and performance evaluation.
