What Is This Tool?
This online converter translates data transfer values from IDE (DMA mode 0), a legacy direct memory access mode for ATA/IDE devices, into Virtual Tributary 1 (payload) units used in SONET/SDH synchronous transport frames. It helps bridge older hardware data rates with modern optical communication formats.
How to Use This Tool?

Tips & Best Practices
-
Verify the equipment compatibility before relying on converted values for network design
-
Consider timing and synchronization factors beyond raw conversion rates when planning interworking
-
Use this converter primarily for legacy and specialized industrial or telecommunication setups
-
Cross-check conversion results where exact synchronization with SONET/SDH frames is critical
Limitations
-
Conversion mainly applies to outdated IDE (DMA mode 0) data rates
-
Differences in timing and overhead between IDE and SONET/SDH require additional handling
-
Conversion rate is nominal and may differ due to specific network or equipment conditions
Frequently Asked Questions
-
What does IDE (DMA mode 0) represent?
-
IDE (DMA mode 0) is the lowest speed direct memory access mode for ATA/IDE devices, moving data blocks directly into memory without CPU involvement.
-
What is a Virtual Tributary 1 (payload)?
-
A Virtual Tributary 1 (payload) is a sub-rate container within SONET/SDH frames used to carry lower bit-rate channels multiplexed into higher-rate optical streams.
-
Why would I convert IDE (DMA mode 0) to Virtual Tributary 1 (payload)?
-
This conversion supports integrating legacy IDE data rates into modern SONET/SDH optical transport networks for interoperability.
