Tips & Best Practices

Use this conversion primarily for theoretical planning rather than real-time monitoring
Recognize that modem (28.8k) rates are informal and may not capture fluctuating throughput
Consider the context carefully when interpreting VT6 units, as they relate to multiplexing PDH payloads
Verify conversions align with network design objectives and equipment specifications

Limitations

Modem (28.8k) speed is an informal fixed rate and may not reflect actual line performance
Virtual Tributary 6 payloads are designed for multiplexing PDH signals and may not correspond to all bit-rate types
This conversion serves mainly theoretical or network planning needs, not real-time throughput measurement
