Easy conversion between T2 (signal) and Virtual Tributary 2 (signal) data transfer units
-
Supports telecommunications engineering applications including network migration and legacy system integration
-
Browser-based and user-friendly interface for quick calculations
Examples
-
1 T2 (signal) equals approximately 2.74 Virtual Tributary 2 (signal)
-
3 T2 (signal) converts to about 8.21875 Virtual Tributary 2 (signal) using the conversion factor
Common Use Cases
-
Mapping legacy medium-capacity T2 leased lines into SONET/SDH networks
-
Configuring telecom equipment for mixed T-carrier and SONET/SDH infrastructure
-
Planning and provisioning capacity in telecom networks that combine older and modern signal formats
Tips & Best Practices
-
Ensure equipment compatibility when working with legacy T2 signals and SONET/SDH VT2 channels
-
Use this conversion for network upgrades that integrate older and newer transmission technologies
-
Verify the framing and overhead differences that may affect practical conversions in hardware
Limitations
-
Conversion assumes legacy equipment; modern networks may favor higher-rate or all-optical systems
-
Variations in signal framing and overhead can impact exact multiplexing during conversion
-
Fractional VT2 channels may require additional hardware framing or padding beyond the conversion factor
Frequently Asked Questions
-
What is T2 (signal) used for?
-
T2 is a legacy digital carrier level used primarily for medium-capacity leased lines and trunking between telephone switches in North America.
-
Why convert T2 (signal) to Virtual Tributary 2 (signal)?
-
Converting enables integration of older T2 signals within modern SONET/SDH networks that carry lower-rate PDH circuits inside higher-rate frames.
-
Can this conversion be used for modern telecom networks?
-
This conversion mainly applies to legacy systems; modern deployments often use higher-rate or all-optical equipment instead.
Key Terminology
