What is a Virtual Tributary 2 (VT2) signal?

Virtual Tributary 2 is a SONET/SDH sub-rate format carrying a 2.048 Mbps payload (an E1 channel) within higher-rate SONET/SDH frames, enabling multiplexing of lower-rate circuits.

Why convert VT2 signals to terabytes per second?

Converting VT2 to TB/s helps understand their equivalent high-level aggregate data rates in terms of modern storage and network bandwidth metrics, assisting capacity planning and performance evaluation.

Does one VT2 signal equal one terabyte per second?

No. One VT2 signal represents 2.048 Mbps, which converts to about 2.619×10⁻⁷ terabyte per second, a very small fraction requiring aggregation for practical use.
