What does 'ISDN (dual channel)' mean?

ISDN (dual channel) refers to combining two 64 kbit/s ISDN B channels for a total data rate of about 128 kbit/s, used in telecommunication systems.

Why convert USB speeds to ISDN rates?

Converting USB to ISDN helps compare modern high-speed USB data transfer rates with legacy ISDN networks for telecommunications planning or benchmarking.

Can this converter handle different USB generations?

The tool recognizes that USB speeds vary by generation, but conversion rates are provided generally; specific USB generation speeds affect conversion significance.

Tips & Best Practices

Understand that ISDN (dual channel) describes throughput from bonded ISDN B channels, not a physical SI unit
Consider USB generation differences as speeds vary greatly
Use conversions primarily for conceptual or legacy network integration purposes
Verify network requirements before basing decisions solely on converted rates

Limitations

ISDN (dual channel) is a telecom rate descriptor, not a standard SI unit, limiting direct equivalence
USB speed varies by generation, which influences conversion relevancy
ISDN throughput is significantly lower than USB, so conversions are mostly conceptual
Direct physical or practical equivalences can be limited due to technology differences
