What does STS48 (signal) represent in telecommunications?

STS48 (signal) is a SONET signal level corresponding to OC-48, providing a synchronous transport rate of 2.48832 Gbit/s for carrying multiplexed digital payloads over optical fiber.

What is Virtual Tributary 6 (payload) used for?

Virtual Tributary 6 (payload) is a SONET/SDH sub-container used to carry defined lower-rate PDH or plesiochronous payloads within a larger synchronous payload envelope.

Why convert from STS48 to Virtual Tributary 6?

Users convert to break down high-capacity SONET signals into manageable lower-rate payloads for efficient grooming, mapping, and transport of legacy and low-rate circuits.

Key Features

Converts STS48 (signal) units to Virtual Tributary 6 (payload) units based on established telecommunications standards.
Supports breakdown of large SONET signals into manageable lower-rate payload containers.
Provides multiple example conversions for user guidance.
Browser-based and easy to use with no installation required.

Examples

2 STS48 (signal) equals 829.44 Virtual Tributary 6 (payload).
0.5 STS48 (signal) equals 207.36 Virtual Tributary 6 (payload).

Common Use Cases

Carrier long-haul and metro backbone links to transport aggregated traffic between central offices.
High-capacity interconnections between core routers or large data centers.
Mapping legacy PDH circuits like DS1/E1 for transport over SONET networks.
Traffic grooming to combine multiple low-rate services within STS-N payloads.
Carrying voice and other low-bandwidth customer circuits in larger SONET/SDH systems.

Tips & Best Practices

Ensure your network equipment supports VT6 multiplexing before conversion.
Use this tool to plan traffic grooming efficiently by breaking high-capacity signals into sub-containers.
Verify synchronous network operation to match the assumed SONET framing in conversions.
Leverage the conversion examples to validate your calculations.

Limitations

Conversion assumes that the network operates synchronously with standard SONET framing.
Equipment compatibility with VT6 multiplexing is required for practical deployment.
Rate granularity is fixed; you cannot allocate partial VT6 payloads independently.
