What does one ISDN (single channel) represent?

It denotes a single ISDN bearer (B) channel with a data-transfer capacity of 64 kilobits per second used in telecommunication systems.

What is OC768 used for?

OC768 is a high-capacity synchronous optical transport level used in fiber-optic backbone links, with a line speed of about 39.8 Gbit/s.

Why are converted values from ISDN to OC768 so small?

Because ISDN channels have much lower data rates compared to the very high capacity of OC768 optical carrier lines.

Tips & Best Practices

Remember that ISDN (single channel) data rates are much lower than OC768 rates
Use this converter to estimate how legacy channels scale into modern optical carrier units
Combine multiple ISDN channels before converting for clearer understanding of scale
Consider network overhead and real-world factors beyond nominal values when planning

Limitations

ISDN (single channel) provides a much lower speed than OC768, so conversions yield very small decimal values
Conversion assumes nominal channel rates without accounting for overhead or performance variations
Not suitable for precise performance measurement or accounting for protocol-specific details
