What is ISDN (dual channel)?

ISDN (dual channel) is a telecommunication data rate descriptor using two 64 kbit/s B channels in parallel to provide about 128 kbit/s throughput.

How is gigabit/second (SI def.) defined?

Gigabit per second (SI definition) is a data rate of 1,000,000,000 bits per second, commonly used to express network link speeds.

Why convert ISDN (dual channel) to gigabit/second?

Conversion allows comparison and integration of legacy ISDN rates with modern network standards for planning and analysis.

Tips & Best Practices

Understand the difference between ISDN (dual channel) service-level rates and standard SI units.
Use conversions to support network capacity planning and performance analysis.
Be mindful that ISDN’s bandwidth is substantially lower than gigabit-speed networks.

Limitations

ISDN (dual channel) reflects a fixed throughput of about 128 kbit/s, much lower than gigabit scales.
Conversion results in very small gigabit values due to ISDN’s limited bandwidth.
Real-world throughput can vary due to channel bonding overhead and differing measurement standards.
