Tips & Best Practices

Always consider protocol and network-layer differences affecting effective throughput
Use the converter for design and planning rather than absolute data throughput measurement
Understand that ISDN (dual channel) refers to a service-level configuration, not a strict SI unit
Take into account that STM-64 capacity includes overhead beyond user data rates

Limitations

ISDN (dual channel) is a service-level descriptor, not a precise unit of measurement
STM-64 represents line capacity and may have overhead impacting actual throughput
The conversion reflects rate comparison, not protocol-specific or network-layer details
Effective data rates can vary depending on network implementation and protocols used
