What does 1 STM-64 signal represent in terms of ISDN (dual channel)?

One STM-64 (signal) corresponds to 77,760 ISDN (dual channel) units, showing how many low-speed ISDN bonded channels equal the high-capacity STM-64 line rate.

Is ISDN (dual channel) an exact SI unit?

No, ISDN (dual channel) is a service-level data rate descriptor reflecting two bonded ISDN B channels and is not an exact international standard unit of data rate.

Can this conversion be used to directly replace STM-64 with ISDN channels?

No, due to the large scale difference, this conversion is mainly for comparative and planning purposes rather than direct practical substitution.

Tips & Best Practices

Use this converter primarily for planning and capacity comparison tasks
Understand that ISDN (dual channel) units reflect service-level rates, not exact SI data rates
Keep in mind the large difference in scale when interpreting conversion results
Apply conversions to assess compatibility and integration options in telecom networks
Verify results with technical specifications when designing network hardware or services

Limitations

ISDN (dual channel) is a service-level descriptor, not a precise SI unit
Conversion provides approximate equivalence in bandwidth, not exact data throughput
Large difference in magnitude limits direct substitution between units
Mainly useful for engineering reference rather than practical channel replacement
