Tips & Best Practices

Ensure you understand the legacy and modern network contexts when converting rates
Use the conversion primarily as a nominal reference since actual throughput can vary
Verify compatibility beyond line rate, considering differences in protocols and multiplexing
Apply this conversion during network planning and integration involving both SONET and PDH
Consult with telecom network engineers for equipment-specific validation and testing

Limitations

Conversion is nominal and does not guarantee exact throughput due to overhead and framing
T4 signals are mostly legacy and seldom seen in new network deployments
Differences in signaling and multiplexing protocols can impact interoperability
This tool focuses solely on converting line rates, not signaling or protocol compliance
