What Is This Tool?
This converter allows you to translate data transfer rates from ISDN (dual channel), a telecommunications rate descriptor, to IDE (PIO mode 3), a programmed I/O transfer mode used in legacy storage devices. It is designed for comparing and understanding throughput differences between these distinct data transfer methods.

Tips & Best Practices
-
Use this tool for approximate conversions to assist with performance benchmarking.
-
Consider additional protocol and overhead factors beyond raw throughput values.
-
Leverage conversion examples to understand scale differences between units.
-
Apply conversions primarily within telecommunications and legacy storage contexts.
-
Verify any critical system decisions with real-world testing alongside conversion results.
Limitations
-
ISDN (dual channel) is not an SI unit but a service-level throughput descriptor, so conversions are approximate.
-
IDE (PIO mode 3) throughput is theoretical maximum and depends on CPU-driven processes, affecting real performance.
-
Conversion does not account for protocol overhead, latency, or environmental factors that impact actual data transfer speeds.
Frequently Asked Questions
-
What does ISDN (dual channel) represent?
-
It refers to using both 64 kbit/s B channels of an ISDN Basic Rate Interface together to achieve a combined data throughput of about 128 kbit/s.
-
What is IDE (PIO mode 3)?
-
IDE (PIO mode 3) is a CPU-driven programmed I/O mode for Parallel ATA/IDE storage devices with a theoretical maximum throughput of about 11.1 MB/s.
-
Can I get exact data transfer speeds from this conversion?
-
No, the conversion is approximate since ISDN is not an SI unit and IDE (PIO mode 3) throughput varies with CPU load and system factors.
Key Terminology
-
ISDN (dual channel)
-
A telecommunication data transfer rate descriptor using two bonded 64 kbit/s B channels to achieve about 128 kbit/s throughput.
-
IDE (PIO mode 3)
-
A CPU-driven programmed I/O transfer mode for legacy Parallel ATA/IDE storage devices with a theoretical maximum throughput of approximately 11.1 MB/s.
-
Channel Bonding
-
The process of combining multiple data channels to increase overall throughput, such as bonding two ISDN B channels.
