Key Features
-
Converts STS24 (signal) data transfer units into Virtual Tributary 6 (payload).
-
Based on the exact conversion rate: 1 STS24 equals 207.36 VT6 payload units.
-
Supports use cases in carrier backbone, metro networks, and SONET/SDH transport systems.
-
Browser-based and easy-to-use interface for quick conversions.
Examples
-
1 STS24 (signal) converts to 207.36 Virtual Tributary 6 (payload).
-
0.5 STS24 (signal) converts to 103.68 Virtual Tributary 6 (payload).
Common Use Cases
-
Breaking down a high-rate SONET signal into multiple VT6 payload containers.
-
Aggregating legacy PDH circuits for efficient optical transport.
-
Transporting low-bandwidth voice or data services within SONET/SDH systems.
-
Managing metro network backhaul and carrier backbone infrastructure.
Tips & Best Practices
-
Verify the network configuration aligns with standard SONET overhead assumptions.
-
Use VT6 payloads primarily for legacy PDH services and sub-STS signals.
-
Cross-check conversions for compatibility with existing telecom infrastructure.
-
Consider the fixed size of VT6 containers when planning service aggregation.
Limitations
-
Conversion assumes typical SONET overhead; actual payload may vary slightly.
-
VT6 payloads are fixed in size and suited only for certain legacy traffic types.
-
Accuracy depends on specific network payload mapping and configurations.
Frequently Asked Questions
-
What does STS24 (signal) represent?
-
STS24 is a Synchronous Optical Network signal formed by multiplexing 24 STS-1 channels, with a nominal rate of about 1.244 Gbit/s.
-
What is Virtual Tributary 6 (VT6) used for?
-
VT6 is a virtual tributary container used to carry lower-rate plesiochronous/PDH payloads within SONET/SDH synchronous frames for grooming and multiplexing.
-
Why convert STS24 (signal) to VT6 (payload)?
-
Conversion breaks down a high-rate SONET signal into multiple lower-rate containers, enabling efficient transport and aggregation of legacy PDH circuits.
