What does STS24 (signal) represent in SONET networks?

STS24 is a synchronous transport signal level 24 created by multiplexing 24 STS-1 channels, with a line rate of about 1.244 Gbit/s used for high-capacity optical transport.

What is the official conversion rate between STS24 and STS12 signals?

One STS24 (signal) equals two STS12 (signal) units according to standard SONET signal hierarchy rates.

Can all network equipment convert between STS24 and STS12?

No, only equipment supporting both STS24 and STS12 interfaces can handle this conversion due to the signal format requirements.

Click the convert button to get the equivalent STS12 (signal) value
Review the results and use them to inform your network planning or bandwidth management

Key Features

Simple conversion between STS24 (signal) and STS12 (signal) units
Supports SONET signal hierarchy conversion with official rate: 1 STS24 equals 2 STS12
Browser-based and easy-to-use interface
Helps visualize SONET data transfer signal breakdowns
Ideal for telecom, metro networks, and data center interconnect use cases

Examples

1 STS24 (signal) converts to 2 STS12 (signal)
3 STS24 (signal) converts to 6 STS12 (signal)

Common Use Cases

Decomposing high-capacity SONET backbone links into smaller regional sub-channels
Managing bandwidth in data center interconnects and telecom network backhauls
Supporting legacy T1/E1 or STS-1 circuits through multiplexing
Implementing protected high-speed circuits in SONET ring architectures

Tips & Best Practices

Ensure network devices support both STS24 and STS12 interfaces before conversion
Use this tool to understand logical signal capacities rather than raw payload data
Combine with other network planning methods for comprehensive bandwidth management
Be aware of SONET overhead, which affects actual usable payload in conversions

Limitations

Conversion focuses on signal hierarchy, not exact payload capacity due to SONET overhead
Requires compatible network equipment capable of handling both STS24 and STS12 signals
Not all payload types scale strictly linearly because of framing and protocol differences
