What is STS12 (signal)?

STS-12 is a SONET transport signal with a synchronous line rate of 622.08 Mbit/s, carrying multiplexed digital payloads plus overhead in synchronous optical networks.

What does STM-64 (signal) represent?

STM-64 signals are part of the SDH standard with a line rate of about 10 Gbit/s, functionally equivalent to SONET OC-192/STS-192.

Why convert from STS12 to STM-64?

Users convert STS12 to STM-64 to align regional SONET network capacities with higher-capacity SDH backbone links for interoperability and aggregation.
