What does one ISDN (single channel) represent?

It represents one ISDN bearer (B) channel with a nominal data-transfer capacity of 64 kilobits per second, used in telecom systems for carrying voice or user data.

What is a T3 (signal) unit?

T3, also called DS3, is a North American digital transmission format carrying multiplexed data at 44.736 megabits per second, created by multiplexing 28 DS1/T1 channels.

Can I use this converter for exact performance measurements?

No, the converter provides nominal data rate estimations and does not account for overhead or exact throughput performance.

Click the convert button to get the equivalent T3 (signal) value
Use the results for network design or capacity planning

Key Features

Converts ISDN (single channel) units to T3 (signal) units accurately
Based on nominal data rates without protocol overheads
Supports aggregation for scaling legacy telephony channels
Useful for network planning and telecom infrastructure integration
Browser-based and easy to use

Examples

10 ISDN (single channel) = 0.014306152 T3 (signal)
50 ISDN (single channel) = 0.07153076 T3 (signal)

Common Use Cases

Aggregating ISDN channels to compare with modern T3 data rates
Planning network upgrades integrating legacy and current telecom systems
Specifying data rates for telecommunications provisioning and equipment
Designing ISP backbone links using mixed legacy and high-capacity formats

Tips & Best Practices

Use conversions as estimations for planning, not exact performance guarantees
Consider ISDN channels as lower capacity units when aggregating
Account for framing and overhead differences separately when designing networks
Verify aggregated data rates align with actual equipment capabilities

Limitations

Conversions are based on nominal data rates and ignore protocol overhead
ISDN channels have significantly lower data rates than T3 signals
Values serve mainly for planning and estimation, not exact throughput
Differences in technology and framing protocols limit direct equivalence
