What Is This Tool?
This converter helps translate data transfer speeds between IDE (DMA mode 2), a legacy PATA device transfer mode, and ISDN (dual channel), a telecommunications data rate descriptor combining two ISDN channels.
How to Use This Tool?
-
Enter the data transfer rate value in IDE (DMA mode 2)
-
Select IDE (DMA mode 2) as the source unit
-
Choose ISDN (dual channel) as the target unit
-
Click the convert button to see the equivalent transfer rate
-
Review results and use them for performance or compatibility assessments

Common Use Cases
-
Configuring or diagnosing legacy PATA/IDE storage devices using DMA modes
-
Translating legacy interface speeds into telecommunication data rates for network planning
-
Benchmarking transfer modes for older hard drives and optical drives
-
Comparing storage interface throughput with ISDN telecommunications channels

Tips & Best Practices
-
Verify the active transfer mode on your IDE device before conversion
-
Use conversions to aid understanding of mixed legacy and telecommunication systems
-
Remember this conversion is conceptual and aims at throughput comparison
-
Cross-check results for use in network or storage diagnostics
-
Consider device and network context when interpreting conversion results
Limitations
-
IDE (DMA mode 2) is a hardware-specific data transfer mode, while ISDN (dual channel) represents a telecommunication data service
-
Conversion is conceptual and not typically used for direct data interchange
-
Does not account for protocol overhead or real-world throughput variability
-
Intended for legacy and niche scenarios rather than modern universal data rate conversions
Frequently Asked Questions
-
What is IDE (DMA mode 2)?
-
It is a Parallel ATA data-transfer mode allowing devices to move data directly to or from system memory with reduced CPU load, improving performance over older PIO modes.
-
What does ISDN (dual channel) mean?
-
It refers to using both 64 kbit/s B channels of an ISDN Basic Rate Interface combined to provide approximately 128 kbit/s throughput.
-
Why convert from IDE (DMA mode 2) to ISDN (dual channel)?
-
To compare legacy storage interface speeds with telecommunications data rates, helping understand performance in mixed technology settings.
Key Terminology
-
IDE (DMA mode 2)
-
A legacy PATA data transfer mode allowing direct memory access with minimal CPU involvement for higher throughput.
-
ISDN (dual channel)
-
A telecommunications rate descriptor using two bonded 64 kbit/s B channels to provide combined data throughput.
-
DMA
-
Direct Memory Access, a method enabling devices to transfer data directly to or from memory without heavy CPU usage.
