What Is This Tool?
This tool allows users to convert data transfer rates between IDE (UDMA mode 2), a Parallel ATA transfer standard, and ISDN (single channel), a digital telephony channel unit, enabling easy comparison and understanding of transfer rates across computing and telecom fields.
How to Use This Tool?
-
Enter the value in IDE (UDMA mode 2) units you want to convert
-
Select ISDN (single channel) as the target unit
-
Click the convert button to see the equivalent number of ISDN channels
-
Use the result to interpret or document data transfer rates across legacy systems
Key Features
-
Converts data transfer units from IDE (UDMA mode 2) to ISDN (single channel)
-
Based on official maximum theoretical transfer rates
-
Supports legacy system performance benchmarking and network provisioning
-
Provides straightforward unit comparison between storage and telecom domains
-
Browser-based and easy to use
Examples
-
1 IDE (UDMA mode 2) equals 4125 ISDN (single channel)
-
2 IDE (UDMA mode 2) equals 8250 ISDN (single channel)
Common Use Cases
-
Configuring and identifying legacy PC BIOS or drive-controller settings for ATA/33 transfers
-
Specifying ISDN B-channel data rates when provisioning telecom lines
-
Benchmarking legacy disk throughput against telecom channel capacities
-
Troubleshooting compatibility issues in PATA systems
-
Documenting legacy telephony and dial-up service throughput in network diagrams
Tips & Best Practices
-
Ensure unit consistency, noting IDE uses bytes per second while ISDN uses bits per second
-
Use this conversion primarily for theoretical rate comparisons and documentation
-
Double-check hardware specifications for real-world transfer rates
-
Apply this tool for integrating or analyzing legacy PC and telecom systems
-
Review legacy system settings when troubleshooting UDMA mode negotiations
Limitations
-
Conversion assumes maximum theoretical transfer rates which may not reflect actual performance
-
IDE (UDMA mode 2) rates are in megabytes per second, ISDN rates are in kilobits per second; careful unit handling is required
-
Real throughput varies due to hardware limits, protocol overhead, and environmental factors
Frequently Asked Questions
-
What does IDE (UDMA mode 2) represent?
-
It is an Ultra DMA transfer mode for Parallel ATA interfaces providing a maximum theoretical transfer rate of about 33.3 megabytes per second for legacy PATA drives.
-
What is an ISDN (single channel)?
-
An ISDN (single channel) corresponds to one B channel with a nominal data capacity of 64 kilobits per second used in Integrated Services Digital Network telecommunication systems.
-
Why convert IDE (UDMA mode 2) to ISDN (single channel)?
-
This conversion helps compare and document legacy disk transfer rates in terms of telecom channel capacities, aiding cross-domain analysis and benchmarking.
Key Terminology
-
IDE (UDMA mode 2)
-
A Parallel ATA transfer mode also known as ATA/33, offering a maximum theoretical data transfer speed of approximately 33.3 MB/s for legacy PATA drives.
-
ISDN (single channel)
-
A digital telephony channel providing 64 kilobits per second capacity, commonly used in legacy Integrated Services Digital Network systems.
