What Is This Tool?
This converter helps transform measurements from T3 (signal), a high-capacity T-carrier digital transmission format, into Virtual Tributary 1 (signal), a logical sub-channel in SONET/SDH networks used to carry lower-rate plesiochronous signals encapsulated inside higher-rate synchronous frames.

Frequently Asked Questions
-
What is a T3 (signal)?
-
T3, also known as DS3, is a North American digital transmission format that carries multiplexed voice and data at 44.736 Mbps by combining 28 DS1/T1 channels with framing and overhead.
-
What is a Virtual Tributary 1 (signal)?
-
Virtual Tributary 1 is a sub-channel within SONET/SDH networks that encapsulates a lower-rate plesiochronous digital signal, allowing independent grooming and switching within the synchronous high-rate frame.
-
Why convert from T3 to Virtual Tributary 1?
-
Converting from T3 to VT1 allows network operators to break down large T3 streams into multiple manageable sub-channels, facilitating flexible routing and efficient bandwidth use in SONET/SDH systems.
