What Is This Tool?
This converter allows you to translate data transfer rates from gigabyte per second (SI definition) into ISDN single channel units, enabling comparison of modern data rates with legacy ISDN channel capacities.
How to Use This Tool?
-
Enter the value in gigabyte per second (SI def.) that you want to convert
-
Select the input unit as gigabyte/second (SI def.) and output unit as ISDN (single channel)
-
Press the convert button to see the result expressed in ISDN B-channels
-
Use the output to assist with network provisioning or legacy system documentation
Key Features
-
Converts data rates from gigabyte/second (SI definition) to ISDN single channel units
-
Displays the equivalent number of ISDN B-channels for a given gigabyte per second value
-
Suitable for telecommunications and network engineering applications
-
Browser-based tool with a simple user interface
Examples
-
2 Gigabyte/second (SI def.) converts to 250000 ISDN (single channel)
-
0.5 Gigabyte/second (SI def.) converts to 62500 ISDN (single channel)
-
1 Gigabyte/second (SI def.) equals 125000 ISDN (single channel)
Common Use Cases
-
Specifying high-speed network link throughput in terms of legacy ISDN channels
-
Planning ISDN line provisioning or channel aggregation for telecommunication systems
-
Describing storage or computing systems data rates in a legacy telecom context
-
Documenting legacy telephony or dial-up capacities in network equipment
Tips & Best Practices
-
Always verify the use case fits legacy or comparative planning needs when converting to ISDN units
-
Use the converter for documentation or equipment configuration involving ISDN channels
-
Remember the fixed ISDN channel rate of 64 kbit/s when interpreting results
-
Avoid using this conversion for direct high-speed network performance calculations
Limitations
-
ISDN single channel unit fixed at 64 kbit/s, much lower than modern data rates
-
Conversion is meant for legacy or comparative purposes, not precise practical application
-
Does not account for protocol overheads or channel condition variations
-
Not suitable for real-time network throughput assessments
Frequently Asked Questions
-
What does 1 Gigabyte/second (SI def.) equal in ISDN single channels?
-
1 Gigabyte/second (SI def.) equals 125000 ISDN single channels, each representing 64 kbit/s.
-
Why convert from gigabyte per second to ISDN channels?
-
Conversion helps express high data rates in terms of multiple legacy ISDN channels for compatibility and legacy network equipment planning.
-
Can I use this conversion for modern high-speed network assessments?
-
No. The ISDN unit reflects much lower speeds and is best suited for legacy system contexts, not modern network performance evaluations.
Key Terminology
-
Gigabyte/second (SI def.)
-
A data transfer rate representing one gigabyte (10^9 bytes) transferred every second, using SI prefixes.
-
ISDN (single channel)
-
A single ISDN bearer channel with a capacity of 64 kilobits per second, used in Integrated Services Digital Network telecommunication systems.
-
Data Transfer Rate
-
The amount of digital data transmitted per unit of time, often expressed in bytes or bits per second.
