Abstract

In this paper, we implemented a SDH synchronous network system based on ITU-T recommendation G.707 - Network node interface for the synchronous digital archy(SDH). For the system, we used signal processing SDH ASIC, and designed a FPGA_Control chip for various signal control and a FPGA_Alignment cllip for data alignment using YHDL(Very high speed integrated circuit Hardware Description Language). For system monitoring, an operation system was developed using ANSI C and executed in CPU (Motorola MPC-860). The system was evaluated by using ANT-20 for data transmission error defection, jitter detection, pointer chocking, and overhead determination.
