What does modem (1200) mean?

Modem (1200) historically indicates a modem speed of about 1,200 bits per second, used in early dial-up systems to describe data transfer rates.

What is ISDN (dual channel)?

ISDN (dual channel) uses both 64 kbit/s B channels of an ISDN Basic Rate Interface bonded together to provide approximately 128 kbit/s data throughput.

Can I use this converter for precise speed measurements?

No, this tool provides nominal throughput conversion and does not account for protocol overhead or line quality impacting actual speeds.

Tips & Best Practices

Confirm unit definitions before converting to ensure accuracy
Use this tool for nominal throughput comparisons rather than precise data rates
Remember that modem (1200) is largely obsolete in modern contexts
Consider line quality and protocol overhead outside this conversion when evaluating effective speeds

Limitations

Conversion reflects nominal throughput and does not capture protocol or line quality effects
Modem (1200) speeds pertain to legacy technology with limited current application
ISDN (dual channel) is a telecom configuration, not a strict SI unit, making comparisons contextual
