Tips & Best Practices

Verify the input value corresponds to bonded B channels in ISDN (dual channel) format.
Use the conversion to aid in planning backbone links and aggregating traffic properly.
Understand that this conversion is a rate descriptor and not an exact SI unit conversion.
Account for network overhead separately as this tool does not include protocol efficiencies.

Limitations

ISDN (dual channel) represents a service-level data rate, not a strict SI unit, so conversion is an approximation.
STS3 signals operate at significantly higher capacities, so converted values may be fractional and represent a portion of a full circuit.
Conversion does not consider protocol overhead, inefficiencies, or actual payload throughput variations.
