What does T1Z (payload) represent?

T1Z (payload) denotes the user-data portion of a T1/DS1 circuit, excluding framing overhead, commonly used in telecommunications to measure usable throughput.

What is STS3c (signal)?

STS3c is a concatenated SONET electrical transport signal combining three STS-1 channels to form a high-bandwidth payload with a gross rate of 155.52 Mbit/s.

Why convert from T1Z (payload) to STS3c (signal)?

Conversion assists in translating legacy T1 throughput data to aggregated SONET signal capacities, supporting bandwidth planning and network modernization efforts.

Browser-based and simple to operate for quick data transfer rate calculations
Facilitates capacity planning, equipment testing, and bandwidth monitoring
Uses the specific conversion rate: 1 T1Z (payload) equals 0.0099279835 STS3c (signal)

Examples

10 T1Z (payload) converts to approximately 0.099279835 STS3c (signal)
50 T1Z (payload) converts to approximately 0.496399175 STS3c (signal)

Common Use Cases

Estimating usable user-data throughput on legacy T1/DS1 links
Relating legacy throughput data to modern SONET transport signal capacities
Capacity planning and provisioning of telecom network backbones and leased-line circuits
Testing and monitoring equipment in metro and backhaul telecommunications networks

Tips & Best Practices

Always distinguish payload data from framing overhead when interpreting T1Z values
Use this converter to align legacy network metrics with modern high-bandwidth transport standards
Verify that conversions assume concatenated STS3c signals for accuracy
Incorporate conversion results in capacity planning to facilitate network upgrades

Limitations

T1Z is an informal, non-standard unit lacking official SI definition
Payload data values exclude framing overhead, so actual rates can differ slightly
Conversion applies only to concatenated STS3c signals and may not be valid for other SONET or optical protocols
