Tips & Best Practices
-
Ensure you use the gross bit rate for conversions, understanding it may not reflect payload throughput.
-
Consider protocol overhead and framing differences when interpreting rates.
-
Use conversions to compare SDH units with Ethernet-based network speeds for clear communication.
-
Cross-check conversions when working with differing standards like SONET.
-
Utilize the tool for quick reference in network engineering and telecommunications planning.
Limitations
-
Conversion reflects gross bit rate without accounting for protocol overhead or framing variations.
-
STM-1 rates are specific to SDH and may not fully represent payload throughput.
-
Additional considerations may be needed for conversions involving other standards like SONET for interface compatibility.
Frequently Asked Questions
