Frequently Asked Questions
-
What is a Virtual Tributary 1 (signal)?
-
It's a logical sub-channel in SONET/SDH that encapsulates a lower-rate digital signal within a synchronous frame and includes pointer and overhead information for independent grooming.
-
Why convert Virtual Tributary 1 (signal) to Virtual Tributary 1 (payload)?
-
To map logical lower-rate signals encapsulated with overhead into standardized payloads enabling efficient transport, switching, and bandwidth use in SONET/SDH networks.
-
Can this conversion be used outside SONET/SDH systems?
-
No, this conversion is specific to SONET/SDH framing and network applications and is not suitable for other data transfer unit contexts.
