Tips & Best Practices

Ensure you are converting the payload portion of the T3 circuit as it excludes overhead
Use the conversion for high-level planning, acknowledging differences in framing and protocol overhead
Combine multiple T3 payloads to approximate the bandwidth of a single STM-64 signal
Verify network requirements align with capacity planning results obtained from the conversion

Limitations

Conversion uses a linear scaling assumption and does not consider protocol overhead differences
T3 payload bandwidth is much lower than STM-64, requiring multiple T3 lines for capacity equivalence
Effective throughput may vary due to network error correction and framing differences
Raw conversion does not represent performance attributes beyond nominal data rates
