What does STS1 (payload) represent?

STS1 (payload) is the user-data capacity inside an STS-1 SONET frame with a usable payload rate of 50.112 Mbps.

How is STS24 (signal) formed?

STS24 (signal) is created by multiplexing 24 STS-1 channels into one higher-rate SONET signal with a nominal line rate of 1,244.16 Mbps.

Why convert from STS1 (payload) to STS24 (signal)?

This conversion helps aggregate multiple STS1 channels into larger signals for efficient transport and better capacity planning in optical networks.

Select STS1 (payload) as the from-unit and STS24 (signal) as the to-unit.
Click the convert button to see the equivalent STS24 (signal) value.
Review the output and use it for planning or provisioning in SONET networks.

Key Features

Converts STS1 (payload) values to STS24 (signal) units based on SONET standards.
Includes unit definitions and use cases for better understanding.
Provides example conversions for reference.
Browser-based and easy to use, requiring no installation.
Supports telecommunications and optical network planning needs.

Examples

10 STS1 (payload) converts to approximately 0.3979 STS24 (signal).
50 STS1 (payload) equals about 1.9893 STS24 (signal).

Common Use Cases

Provisioning OC-1/STS-1 circuits on carrier backbones to carry DS3 or multiple DS1 channels.
Capacity planning for SONET rings by calculating aggregate throughput.
Mapping tributary signals into STS-1 payload for optical transport.
Aggregating multiple STS-1 channels into STS-24 signals for long-haul optical links.
Backhauling metro networks with combined Ethernet, voice, or leased-line services.

Tips & Best Practices

Use the converter to understand scaling of payload capacity into aggregate signals.
Consider SONET overhead when planning using conversion results.
Verify conversion assumptions align with your network’s protocol framing and line conditions.
Use examples as a guide to validate your calculations.

Limitations

Conversion rates reflect nominal values; actual payload capacity may vary with overhead.
Differences between payload and line rates due to protocol framing must be accounted for.
Assumes linear multiplexing without additional overhead or signal loss.
Not suitable for non-SONET or protocols with differing framing structures.
