Frequently Asked Questions
-
What is a Virtual Tributary 1 (signal)?
-
It is a logical sub-channel within SONET/SDH that encapsulates a lower-rate plesiochronous digital signal, allowing independent grooming and switching in the network.
-
What does STM-64 (signal) represent?
-
STM-64 is a Synchronous Transport Module level 64 signal in SDH with about 10 Gbit/s line rate, used for high-capacity core and long-haul fiber links.
-
Why convert Virtual Tributary 1 to STM-64?
-
Conversion facilitates aggregating many VT1 streams into a high-capacity STM-64 signal for efficient backbone transmission and network management.
