-
Supports telecommunications and network engineering applications
-
Browser-based and easy to use for quick data unit translation
Examples
-
1 VT2 payload equals approximately 0.6497461929 T1C signal
-
5 VT2 payloads convert to about 3.2487309645 T1C signals
Common Use Cases
-
Transporting E1 voice or data circuits over SONET/SDH networks
-
Converting data for leased-line business Internet or WAN links
-
Supporting PBX-to-carrier voice trunk connections
-
Enabling circuit emulation and PDH-to-SONET transport

Tips & Best Practices
-
Use this tool to ensure correct provisioning between SONET/SDH and T1 infrastructures
-
Verify network compatibility as overhead and framing differences may affect throughput
-
Apply conversions primarily for design and planning in telecommunications
-
Confirm unit selections before converting data transfer rates
Limitations
-
Fixed conversion rate does not consider overhead or line coding variations
-
Real transmission throughput may differ due to additional framing and synchronization
-
Potential compatibility issues exist when interconnecting differing network standards
Frequently Asked Questions
-
What does a Virtual Tributary 2 (payload) represent?
-
It is a SONET/SDH container designed to carry a 2.048 Mb/s PDH/E1 channel, enabling multiplexing of lower-rate signals over optical networks.
-
What is the T1C (signal) used for?
-
T1C is a North American T1 digital carrier transmitting 1.544 Mb/s with 24 channels, commonly used for voice and data transport on leased or trunk lines.
-
Why is conversion between VT2 (payload) and T1C (signal) important?
-
It allows translating data rates for integrating legacy TDM circuits across SONET/SDH and T1 systems, ensuring proper provisioning and interoperability.
