Tips & Best Practices
-
Ensure correct selection of source and target units based on SONET/SDH architecture.
-
Use this tool to plan bandwidth aggregation for efficient network capacity management.
-
Verify the network compatibility with VT and STS hierarchies before conversion.
-
Consider that overhead and protocol framing are not included in the conversion.
Limitations
-
Conversion presumes fixed slot sizes and transport rates established by SONET standards.
-
Does not factor in overhead or protocol framing which affect actual payload bandwidth.
-
Applicable only within SONET/SDH network contexts supporting the VT and STS hierarchy.
Frequently Asked Questions
-
What is Virtual Tributary 1 (payload)?
-
It is a sub-rate container within a SONET/SDH frame used to carry lower-rate signals multiplexed into higher-rate optical streams, standardizing slot sizes for mapping channels like DS1/T1.
-
What does STS48 (signal) represent?
-
STS48 is a SONET signal level equivalent to OC-48, offering a transport rate of approximately 2.48832 Gbit/s for multiplexed digital payloads over optical fiber.
-
Why convert Virtual Tributary 1 (payload) to STS48 (signal)?
-
This conversion aggregates low-rate signals into a high-capacity synchronous transport frame, facilitating efficient transmission and bandwidth management in optical networks.
