THE ALIGNMENT TYPE PAYLOAD MAPPING MACHINE FOR TRIBUTARY UNIT GROUP 21 SERIAL INTERFACE

摘要

The container composes the format of TUG21 serial frame at the speed of 12.096 Mbps to process all data using a single clock of 12.528 MHz and simplify the hardware of multiplexing and demultiplexing circuits, and deaccelerates the process speed of mux/demux to stabilize the operation. It includes several serial/parallel converters (2) for generating parallel TUG21 data, several multiplexers (5) for multiplexing the parallel TUG21 data, and a retiming flip flop section (6) for generating C32 data.
