Tips & Best Practices
-
Consider the bandwidth mismatch when mapping 100 Mbps Ethernet to 155.52 Mbps STS3
-
Use appropriate multiplexing or encapsulation equipment for proper signal handling
-
Account for synchronization and framing differences between Ethernet and SONET signals
-
Verify network configurations to ensure seamless integration of converted data rates
Limitations
-
Conversion results in underutilized capacity due to the lower Ethernet (fast) data rate
-
Requires additional hardware or protocols to handle differing physical layers and framing
-
Synchronization and overhead differences must be addressed in practical deployments
