Tips & Best Practices
-
Verify compatibility of SONET/SDH framed signals with bit-rate conversions
-
Use this conversion for estimating and comparing channel capacities
-
Avoid confusing the SI terabit unit with binary-derived tebibit units
-
Leverage examples to understand scaling of VT2 signals to terabits
-
Apply conversion results when planning network capacity and provisioning
Limitations
-
Conversion is approximate given VT2’s fixed 2.048 Mbps payload rate compared to absolute SI units
-
Results depend on interpreting framed signals as pure bit rates
-
Binary prefix tebibit should not be mistaken for SI terabit in precise scenarios
Frequently Asked Questions
-
What is a Virtual Tributary 2 (VT2) signal?
-
A VT2 signal is a SONET/SDH sub-rate format carrying a 2.048 Mbps payload, representing an E1 channel, used to multiplex lower-rate PDH circuits into higher-rate SONET/SDH frames.
-
How is terabit/second (SI def.) defined?
-
Terabit per second (SI definition) is a data transfer rate unit representing 10^12 bits transmitted each second, with 'tera' denoting one trillion in the SI system.
-
Why should I not confuse terabit with tebibit?
-
Because terabit uses the decimal SI prefix (10^12 bits), while tebibit is a binary prefix (2^40 bits) and they differ significantly in data quantity.
