Frequently Asked Questions
-
What does gigabit per second (SI def.) represent?
-
It is a data transfer rate equal to one billion bits per second and is commonly used in networking and communications to express link capacity and throughput.
-
What is a Virtual Tributary 1 (payload)?
-
It is a sub-rate container within a SONET/SDH synchronous transport frame used to multiplex lower-rate signals into higher-rate optical transport streams.
-
Why convert from gigabit/second to Virtual Tributary units?
-
This conversion helps translate high-speed network data rates into standardized lower-rate containers for efficient multiplexing, switching, and interworking in SONET/SDH networks.
