What is an ISDN (single channel)?

It is a single ISDN bearer channel used for voice or data transmission at 64 kilobits per second in Integrated Services Digital Network systems.

What does T4 (signal) represent?

T4 (signal) is a high-order trunk signal in the North American T-carrier hierarchy that carries multiple lower-order channels at about 274.176 megabits per second.

Why are conversion results from ISDN to T4 so small?

Because ISDN channels have a low capacity of 64 kbps, while T4 signals operate at much higher rates (around 274 Mbps), resulting in small fractional values.

Click the convert button to see the equivalent value in T4 (signal).

Key Features

Converts between ISDN (single channel) and T4 (signal) data rates.
Supports legacy telecommunications unit conversions relevant for engineering and network provisioning.
Browser-based and easy to use without any software installation.

Examples

10 ISDN (single channel) converts to approximately 0.002334267 T4 (signal).
100 ISDN (single channel) converts to approximately 0.02334267 T4 (signal).

Common Use Cases

Relating ISDN channel capacities to larger T4 backbone carrier signals in legacy telecommunication contexts.
Configuring network equipment involving ISDN provisioning alongside PDH T-carrier systems.
Supporting historical analysis or maintenance of obsolete long-distance backbone links.

Tips & Best Practices

Double-check unit selections before conversion to ensure accurate results.
Use this converter primarily for legacy network equipment or historical data comparisons.
Consider the small fractional values involved when converting low-capacity ISDN channels to high-capacity T4 signals.

Limitations

Applies mostly to legacy telecommunication systems being replaced by modern networks like SONET/SDH.
T4 signals have fixed high capacity, making conversions from ISDN channels result in very small decimal values.
T4 usage is limited due to obsolescence in current telecommunications infrastructure.
