What is a Virtual Tributary 1 (signal)?

It is a logical sub-channel in SONET/SDH networks used to carry lower-rate circuits transparently within a higher-rate synchronous frame.

How does terabit/second (SI def.) differ from tebibit per second?

Terabit/second (SI def.) uses decimal multiples (10^12 bits), while tebibit per second is based on binary multiples (2^40 bits); they represent different quantities.

Why convert Virtual Tributary 1 signals to terabit/second?

Converting allows integration of legacy SONET/SDH channel bandwidths into modern high-capacity data transfer metrics for network planning and monitoring.
