Frequently Asked Questions
-
What does Virtual Tributary 1 (signal) represent?
-
It is a logical sub-channel in SONET/SDH networks encapsulating lower-rate digital signals for efficient transport and independent management.
-
What is modem (28.8k) speed?
-
It is an informal unit representing a data transfer rate of 28.8 kilobits per second typical of a classic dial-up modem connection.
-
Why convert between these two units?
-
Converting helps compare modern synchronous transport stream capacities with legacy modem speeds, aiding bandwidth planning and network analysis.
