Conversion is based on standardized line rates and may not capture overhead or payload variations specific to equipment
-
Network management techniques, error correction, and framing overhead can affect practical capacity
-
Interoperability constraints between SDH and SONET devices can limit precise bandwidth usage
Frequently Asked Questions
-
What is STM-16 (signal)?
-
STM-16 (signal) is a Synchronous Digital Hierarchy (SDH) line rate with a gross bit rate of 2.48832 Gbit/s, used to carry multiplexed digital channels in carrier networks.
-
What does Virtual Tributary 6 (signal) represent?
-
Virtual Tributary 6 (VT6) is a logical sub-channel in SONET, used to transport lower-rate signals inside an STS-1 payload by byte-interleaving and bandwidth grooming.
-
Why convert STM-16 to Virtual Tributary 6?
