What Is This Tool?
This converter allows users to translate data transfer rates from Virtual Tributary 2 (payload), a SONET/SDH channel container for 2.048 Mb/s PDH/E1 signals, to IDE (DMA mode 0), the initial DMA transfer mode for ATA/IDE devices. It bridges different technological domains, aiding compatibility between optical network and legacy storage transfer rates.

-
10 Virtual Tributary 2 (payload) equals 0.60952381 IDE (DMA mode 0)
Common Use Cases
-
Transport of E1 (2.048 Mb/s) voice or data channels over SONET/SDH optical backbones
-
Circuit emulation and mapping legacy TDM services into optical networks
-
Managing low-rate channel grooming within high-capacity optical links
-
Configuring legacy PATA hard drives operating in their lowest DMA mode
-
Supporting embedded systems using IDE interfaces to optimize CPU usage
-
Device driver configuration for IDE DMA modes during system startup
Tips & Best Practices
-
Verify the type of data transfer unit before conversion to ensure accuracy
-
Use the tool for rough comparisons between optical network channels and legacy IDE transfer modes
-
Consider that this conversion uses idealized rates and may not reflect real-world device performance
-
Remember that IDE (DMA mode 0) is a low-speed mode; modern interfaces may require different handling
Limitations
-
Conversion links technologies with different data framing and transfer protocols, so performance may not be directly comparable
-
IDE (DMA mode 0) is a low-speed transfer mode and may not represent modern data transfer speeds
-
Calculated results don’t include overheads such as error correction or hardware limitations
Frequently Asked Questions
-
What is Virtual Tributary 2 (payload)?
-
It is a SONET/SDH virtual tributary container that carries a 2.048 Mb/s PDH/E1 channel for multiplexing TDM signals into higher-rate optical frames.
-
What does IDE (DMA mode 0) refer to?
-
IDE (DMA mode 0) is the lowest-speed direct memory access transfer mode defined for ATA/IDE devices, allowing data transfer with minimal CPU involvement.
-
Why convert between these two units?
-
Users convert to translate data rates between optical network channels and legacy IDE transfer modes, assisting compatibility and system performance matching.
Key Terminology
-
Virtual Tributary 2 (VT2)
-
A SONET/SDH container for carrying 2.048 Mb/s PDH/E1 channels to multiplex low-rate signals into optical frames.
-
IDE (DMA mode 0)
-
The initial direct memory access mode for ATA/IDE devices, designed to transfer data blocks to memory with minimal CPU involvement.
-
DMA (Direct Memory Access)
-
A data transfer mode that allows devices to move data directly to or from memory without burdening the CPU.
