-
100 Virtual Tributary 2 (payload) equals 0.2048 gigabit/second (SI def.).
Common Use Cases
-
Transporting legacy E1 voice or data circuits within high-speed optical networks.
-
Converting legacy SONET/SDH channel rates for comparison to modern network bandwidths.
-
Evaluating and provisioning low-rate channels inside high-capacity optical links.
-

Tips & Best Practices
-
Ensure correct selection of source and target units to avoid confusion.
-
Use this conversion to interpret SONET/SDH legacy channel rates in terms of gigabit bandwidth.
-
Be mindful that the gigabit/second unit follows the decimal SI standard, distinct from binary data rate units.
-
Apply conversions only within telecommunications contexts involving SONET/SDH infrastructure.
Limitations
-
Virtual Tributary 2 is specific to SONET/SDH and does not represent packet-based or non-PDH rates.
-
The SI gigabit/second uses decimal units and is not the same as binary-based gibibit/second.
-
Conversion does not consider overhead or signaling inefficiencies inherent to real networks.
Frequently Asked Questions
-
What does Virtual Tributary 2 (payload) measure?
-
It measures a SONET/SDH virtual tributary channel sized to carry a 2.048 Mb/s PDH/E1 signal, used for multiplexing lower-rate TDM circuits.
-
How is gigabit/second (SI def.) different from gibibit/second?
-
Gigabit/second (SI) is based on decimal units (10^9 bits per second), while gibibit/second uses binary units (2^30 bits), so the two represent different quantities.
-
Why convert VT2 payload rates to gigabit/second?
-
To quantify legacy SONET/SDH channel rates in terms of modern standardized data rates, enabling easier comparison and interoperability across network technologies.
