Tips & Best Practices
-
Verify that the network uses standard SONET and PDH signal rates for accurate conversion
-
Consider protocol overhead and physical layer constraints in practical deployments
-
Use this converter mainly in legacy SONET/SDH network environments
-
Double-check results when planning capacity for multiplexed circuit configurations
Limitations
-
Conversion assumes standard SONET and PDH rates; actual network variations can affect capacity
-
Primarily applies to legacy and interworking networks, not modern Ethernet/IP systems
-
Physical impairments and multiplexing constraints may limit use of full theoretical capacity
Frequently Asked Questions
-
What does 1 OC24 represent in terms of data rate?
-
1 OC24 corresponds to a SONET rate equal to 24 times the OC-1 base rate of 51.84 Mbit/s, totaling 1,244.16 Mbit/s.
-
Why convert OC24 to Virtual Tributary 2 (signal)?
-
Converting OC24 to Virtual Tributary 2 (signal) enables breaking down high-capacity SONET channels into smaller 2.048 Mbps E1 circuits for easier traffic grooming and provisioning.
-
Is this conversion applicable to modern Ethernet-based networks?
-
No, this conversion is mainly intended for legacy SONET/SDH network management and interworking with PDH services rather than modern Ethernet/IP systems.
