-
Interfacing between SDH networks and Ethernet-based LANs or data centers.
-
Planning network infrastructure integrating legacy SDH and modern Ethernet technologies.
Tips & Best Practices
-
Consider the nominal conversion value as reference, not actual throughput under all conditions.
-
Use this tool when planning hybrid environments involving both SDH and Ethernet.
-
Account for protocol and signaling differences by employing appropriate interfacing equipment.
-
Verify network equipment compatibility based on standardized unit rates.
Limitations
-
Conversion is based on nominal bit rates and does not include protocol overhead or real-time transmission performance.
-
Differences in framing and signaling methods between SDH and Ethernet require extra hardware for full interoperability.
-
Cannot reflect actual network throughput variations due to traffic or physical layer conditions.
