-
May not precisely apply to non-SONET optical transport protocols or custom networks
Frequently Asked Questions
-
What does Virtual Tributary 1 (payload) represent?
-
It is a standardized sub-rate container within a SONET/SDH frame used to carry lower-bit-rate signals multiplexed into high-speed optical transport streams.
-
Why convert megabytes per second to VT1 payload units?
-
This conversion helps network engineers map general data transfer speeds to SONET/SDH payload slots for efficient telecommunications multiplexing and bandwidth management.
-
Does the definition of a megabyte affect the conversion?
-
Yes, the difference between decimal (10^6 bytes) and binary (2^20 bytes) megabyte definitions can impact the exact bit rates and thus the conversion precision.
