What Is This Tool?
This converter allows you to transform data transfer values from Virtual Tributary 2 (signal), a SONET/SDH sub-rate format carrying a 2.048 Mbps payload, into STS12 (signal), a higher-rate SONET transport signal with a line rate of 622.08 Mbps. It is helpful for telecom professionals managing network multiplexing and provisioning.
How to Use This Tool?
-
Enter the value in Virtual Tributary 2 (signal) units you want to convert.
-
Select Virtual Tributary 2 (signal) as the source unit.

Examples
-
Converting 10 Virtual Tributary 2 (signal) results in 0.037037037 STS12 (signal).
-
Converting 100 Virtual Tributary 2 (signal) results in 0.37037037 STS12 (signal).
Common Use Cases
-
Aggregating multiple E1 payloads into a higher-rate SONET transport signal for backbone transmission.
-
Configuring multiplexing equipment in telecom networks integrating PDH channels with SONET.
-
Planning capacity and provisioning in carrier or ISP metro fiber networks.

Tips & Best Practices
-
Use the converter to assist in network equipment configuration and traffic aggregation.
-
Verify compatibility of your network’s signal formats before conversion.
-
Apply conversions specifically within SONET/SDH contexts for accurate results.
-
Consider SONET framing overhead when designing actual network capacity.
Limitations
-
Conversion assumes ideal multiplexing without losses beyond standard SONET framing.
-
Applicable only within SONET/SDH systems; not suitable for non-SONET or newer signal standards.
