Tips & Best Practices

Use the converter to understand and benchmark legacy telecom capacities against modern systems.
Remember that T4 (signal) is a historical unit with slower rates than modern multi-terabit networks.
Apply conversions primarily when maintaining or analyzing legacy networks or equipment.
Do not consider overhead or encoding differences during conversion, as they are not included in this rate.

Limitations

T4 (signal) represents outdated PDH infrastructure speeds and is much slower than current multi-terabit networks.
Conversion does not factor in framing, overhead, or encoding, which influence actual throughput.
The unit is mainly historical or specialized and rarely used in current high-speed network designs.
