What does STS48 (signal) represent?

STS48 (signal) is a SONET signal level equivalent to OC-48 providing a synchronous transport rate of 2.48832 Gbit/s for multiplexed digital payloads over optical fiber.

What is STS3 (payload)?

STS3 (payload) indicates the user-data portion within an STS‑3 SONET transport channel, reflecting the capacity available for client traffic excluding framing and overhead.

Why convert from STS48 (signal) to STS3 (payload)?

Conversion helps assess equivalent user-data capacity within lower-rate payload channels, aiding in network provisioning, billing, and managing traffic over SONET networks.

How to Convert from STS48 (signal) to STS3 (payload)?

Learn the method to convert data transfer rates from STS48 (signal), a high-capacity SONET transport signal, to STS3 (payload), the user-data portion of SONET STS-3 frames for telecom and network planning.

What Is This Tool?

This converter facilitates the transformation of data transfer units from STS48 (signal), a synchronous optical networking transport level, into STS3 (payload), representing the client traffic capacity within SONET transport channels. It’s essential for telecom network planning, billing, and traffic management.

How to Use This Tool?

Enter the amount in STS48 (signal) you wish to convert
Select STS48 (signal) as the source unit and STS3 (payload) as the target unit
Initiate the conversion to see the equivalent user-data capacity in STS3 (payload)
Use the results for network provisioning, billing, or traffic management purposes

Key Features

Converts STS48 (signal) units to STS3 (payload) units accurately
Based on SONET transport signal standards and payload definitions
Supports network planning and service-level agreement analysis
Browser-based and easy to use without complex setup

Examples

1 STS48 (signal) equals approximately 16.55 STS3 (payload)
2 STS48 (signal) converts to about 33.10 STS3 (payload)

Common Use Cases

Carrier backbone and metro network capacity planning
Mapping high-capacity signals to lower-rate payload channels for telecom provisioning
Billing and SLA monitoring for leased transport services
Interconnecting core routers and data centers over optical fiber

Tips & Best Practices

Always consider SONET framing and overhead when interpreting payload capacities
Use this conversion for SONET-based network architectures only
Apply conversions to support accurate capacity planning and SLA compliance
Validate conversions with network specifications and operational requirements

Limitations

Payload values exclude SONET framing and overhead bytes, so capacity is less than raw line rate
Efficiency variations in payload utilization may impact exact usable capacity
Conversion only applies within SONET signal systems, not valid for non-SONET transports
