Abstract
A single-chip synchronous optical network/synchronous digital hierarchy (SONET/SDH) overhead terminator has been designed for use in STS-3, STS-3C, and STM-1 applications. The chip has been fabricated in a 1 μm CMOS process and contains 220000 transistors. The features supported by the chip include overhead extraction, overhead insertion, alarm detection, alarm generation, performance monitoring, pointer tracking, pointer generation, payload retiming, and payload realignment. The architecture of the IC and several of the chip´s more interesting features are described
