What is STM-16 (signal)?

STM-16 is a standardized SDH signal level with a gross bit rate of 2,488.32 Mbit/s used to carry multiplexed digital channels in telecom carrier networks.

What does Virtual Tributary 1 (signal) mean?

Virtual Tributary 1 is a logical sub-channel within SONET/SDH that encapsulates lower-rate signals inside a higher-rate frame, allowing independent grooming and switching.

Why convert STM-16 signals to Virtual Tributary 1 streams?

This conversion helps break down high-capacity signals into smaller tributaries for easier management, grooming, and transport of individual sub-rate services.
