What does 1 terabit per second represent?

It represents a data transfer rate of one trillion bits per second, used to quantify high-speed digital throughput in networks.

What is a Virtual Tributary 2 (VT2) payload used for?

It is used to carry a 2.048 Mb/s PDH/E1 channel, enabling transport of lower-rate TDM signals within SONET/SDH optical networks.

Why convert Tb/s to VT2 payloads?

To translate very high data rates into manageable counts of legacy time-division multiplexed channels for network planning and provisioning.
