| Abstract: | Aiming at the characteristics of test instruments, this paper puts forward the detailed requirements of STM-1 multiplexer/demultiplexer, and introduces the theory and method of the design for MUXer/DEMUXer. Moreover, this paper analyzes timing sequence design of the MUXer, pointer adjustment design and overhead series generation design. All designs are integrated in FPGA. This new technology has been widely used in series of SDH transmission analyzers, suitable for test of malitary and civilian telecommunication network. |
