Abstract :
A Unique CMOS Section Overhead (SOH) processor has been designed for use in 10 Gbit/s SDH-based optical transmission system. A uniquely structured chip makes it possible to use parallel processing of STM-64 SOH at low speed with four identical chips. The features supported by the chips include STM-64 SOH insertion and extraction including Regenerator Section Trace (RST), frame alignment word insertion, alarm detection and generation, and performance monitoring. This paper introduces a novel parallel circuit design methodology for processing STM-64 SOH and describes the unique architecture, implementation and experimental test results of the chip, SOH processor. This paper also presents the implementation methodology of RST using CRC-7 polynomial algorithm
