What does one ISDN (single channel) represent in terms of data rate?

One ISDN (single channel) represents a bearer channel with a nominal data rate of 64 kilobits per second used in telecommunications for voice or data.

What is an STS3 (signal) used for?

STS3 is a synchronous transport signal with a line rate of 155.52 megabits per second used for multiplexing multiple lower-rate channels across synchronous optical or electrical networks.

Why convert ISDN channels to STS3 signals?

Converting ISDN channels to STS3 signals helps aggregate lower-rate channels into higher-capacity SONET transport signals, facilitating network planning and integration between legacy and modern systems.

Key Features

Converts ISDN single channel data capacity to STS3 synchronous transport signals.
Provides exact conversion using standard nominal data rates for ISDN and STS3.
Supports telecom provisioning, network capacity planning, and equipment configuration.
Includes examples to demonstrate typical conversion scenarios.

Examples

Converting 10 ISDN channels results in 0.004115226 STS3 signals.
Converting 100 ISDN channels results in 0.04115226 STS3 signals.

Common Use Cases

Specifying data rates when provisioning ISDN B-channels and configuring network links.
Aggregating multiple ISDN channels into higher-rate SONET synchronous transport signals.
Planning fiber-optic backbone capacities with legacy and modern telecommunications equipment.
Migrating legacy ISDN digital telephony services to SONET/SDH infrastructures.

Tips & Best Practices

Verify the number of ISDN channels before conversion for accurate capacity planning.
Understand that fractional STS3 values represent aggregated capacity and may require multiplexing.
Use this converter as a planning tool, considering network overhead and encoding are not included.
Combine multiple ISDN channels logically or physically to achieve desired STS3 bandwidth.

Limitations

Conversion is based on fixed nominal data rates and ignores overhead or line impairments.
ISDN channels are discrete; fractional aggregation may need additional equipment or logic.
This tool does not account for variations in encoding schemes or network conditions.
