What Is This Tool?
This converter allows you to transform data transfer measurements from T0 (B8ZS payload), a raw T-carrier bitstream format with bipolar 8-zero substitution encoding, to Virtual Tributary 2 (VT2) signal format used in SONET/SDH networks for carrying 2.048 Mbps payloads such as E1 channels.
How to Use This Tool?

-
100 T0 (B8ZS payload) converts to 2.77777778 Virtual Tributary 2 (signal)
Common Use Cases
-
Encapsulating T1 or TDM circuits with preserved B8ZS coding for transport over packet networks
-
Troubleshooting by capturing or replaying raw T-carrier traffic in test equipment
-
Configuring SONET multiplexers or digital cross-connects to groom lower-rate PDH channels
-
Transporting E1 (2.048 Mbps) circuits over SONET backbones
-
Capacity planning and provisioning in telecom networks integrating legacy TDM and modern optical systems
Tips & Best Practices
-
Ensure line coding preservation assumptions are applicable before using conversion results
-
Use this tool primarily for signal format encapsulation rather than direct bit-rate translation
-
Verify compatibility of framing and multiplexing techniques in practical deployments
-
Apply conversion results to support interoperability between TDM and SONET/SDH network equipment
-
Use alongside network provisioning and digital cross-connect configuration processes
Limitations
-
Conversion is based on preserving line coding and payload integrity rather than exact bit-rate equivalence
-
Differences in framing, overhead, and multiplexing methods may affect how the conversion applies practically
-
This tool is suited for signal format encapsulation, not for direct raw data rate conversions
-
Results may not account for all variations in telecom equipment implementations
-
Use in conjunction with network expertise to handle protocol and signal processing differences
Frequently Asked Questions
-
What does T0 (B8ZS payload) represent?
-
T0 (B8ZS payload) is a raw T-carrier bitstream encoded with Bipolar 8-Zero Substitution, preserving the line coding for TDM telephony or data transport.
-
What is Virtual Tributary 2 used for?
-
Virtual Tributary 2 carries a 2.048 Mbps payload, such as an E1 channel, inside SONET/SDH frames for multiplexing lower-rate PDH circuits.
-
Why convert T0 (B8ZS payload) to Virtual Tributary 2 signal?
-
This conversion enables interoperability between legacy T-carrier formats and modern SONET/SDH systems for network provisioning and equipment compatibility.
Key Terminology
-
T0 (B8ZS payload)
-
A raw T-carrier bitstream encoded using Bipolar with 8-Zero Substitution, preserving time-division multiplexed telephony/data channels.
-
Virtual Tributary 2 (VT2)
-
A SONET/SDH sub-rate signal format carrying a 2.048 Mbps payload such as an E1 channel inside higher-rate SONET/SDH frames.
-
B8ZS
-
Bipolar with 8-Zero Substitution, a line coding technique that replaces long runs of zeros with bipolar violations for clock recovery.
