Frequently Asked Questions
-
What does Virtual Tributary 2 (signal) represent?
-
Virtual Tributary 2 is a SONET/SDH sub-rate signal format carrying a 2.048 Mbps payload, typically transporting E1 circuits within higher-rate SONET/SDH frames.
-
What is an OC1 signal?
-
OC1 is the base SONET optical transmission rate of 51.84 Mbps, corresponding to the STS-1 electrical signal used in synchronous optical networking.
-
Why would I convert Virtual Tributary 2 signals to OC1?
-
Converting helps map and aggregate lower-rate PDH E1 channels into higher-capacity SONET optical transport units, essential for capacity planning and provisioning in telecom networks.
