Examples
-
10 Virtual Tributary 6 (signal) equals 0.006341628 STM-64 (signal).
-
1000 Virtual Tributary 6 (signal) equals 0.6341628 STM-64 (signal).
Common Use Cases
-
Mapping multiple lower-rate PDH/TDM circuits over SONET using VT6 channels.
-
Traffic grooming and bandwidth allocation in add/drop multiplexers and SONET cross-connects.
-
Carrying legacy plesiochronous signals over SONET/SDH optical networks.
-
Aggregating low-rate SONET VT6 channels into high-capacity SDH STM-64 links.
-
Interconnecting SONET and SDH systems in carrier backbone networks.
Tips & Best Practices
-
Ensure standard SONET/SDH signal definitions to maintain conversion accuracy.
-
Use this conversion for logical capacity estimation rather than physical layer throughput.
-
Apply conversion when planning network bandwidth grooming and signal aggregation.
-
Verify network equipment compatibility with VT6 and STM-64 signaling standards.
Limitations
-
Conversion is based on standard SONET/SDH signal definitions; overhead variations may influence throughput.
-
Conversion rate reflects logical channel capacity and excludes framing or protocol overhead at physical layers.
Frequently Asked Questions
-
What is a Virtual Tributary 6 (VT6) signal?
-
A VT6 is a logical sub-channel in SONET used to carry and multiplex lower-rate client signals within an STS-1 payload for bandwidth grooming.
