Frequently Asked Questions
-
What does gigabit per second (SI def.) represent?
-
It is a data transfer rate equal to 1,000,000,000 bits per second, measuring how many bits are transmitted or processed each second, commonly used in networking and communications.
-
What is a Virtual Tributary 2 (signal)?
-
A Virtual Tributary 2 is a SONET/SDH sub-rate signal format that carries a 2.048 Mbps payload (an E1 channel) within higher-rate SONET/SDH frames, enabling multiplexing of lower-rate circuits.
-
Why convert gigabit/second to Virtual Tributary 2 signals?
-
This conversion helps telecom engineers translate broadband speeds into the number of E1 channels carried within SONET/SDH infrastructure for network design and capacity planning.
