What Is This Tool?
This tool converts data transfer measurements from T2 (signal), a medium-capacity legacy telecom format, to Virtual Tributary 1 (payload), a sub-rate container used in modern SONET/SDH optical transport systems.
How to Use This Tool?
-
Enter the value in T2 (signal) representing the data transfer rate to convert
-
Select T2 (signal) as the source unit
-
Choose Virtual Tributary 1 (payload) as the target unit
-
Run the conversion to receive the equivalent value in Virtual Tributary 1 (payload)
-
Use the results to assist with telecom legacy system integration or optical network planning
Key Features

-
Apply conversions primarily when working with existing legacy infrastructure
-
Cross-check conversion results with network design requirements for accuracy
Limitations
-
T2 (signal) is an outdated format rarely used in new systems
-
Conversion is mostly relevant for legacy infrastructure upgrades
-
Specialized hardware required to handle differences in signal framing and overhead
-
Maintaining accurate timing and alignment is critical during conversion
Frequently Asked Questions
-
What is T2 (signal) used for?
-
T2 (signal) was used in telecommunications for medium-capacity leased lines and trunking between switches in legacy T-carrier systems.
-
Why convert T2 (signal) to Virtual Tributary 1 (payload)?
-
Converting allows integration of older T2 lines into SONET/SDH optical networks, enabling efficient transport and switching of lower-rate channels in modern systems.
-
Can I use this conversion for new deployments?
-
T2 is mostly legacy and seldom used in new installations; conversion mainly serves existing infrastructure upgrading to optical transport.
