Arquitetura e implementação de interface de linha física para um comutador ATM.

Abstract

This Master Degree dissertation describes the physical interface (ILF) architecture of a AIM lw4N switch (COMATM). The ILF is a flexible and modular architecture which can be use-' with physical layer standards 155Mbps SDH/SONET or TAXI (100 Mbps). Its interface with the ATM Switching Module (MCOA), implementing the ATM layer functions, is based on UTOPIA standard signals. We'll point out in this trhesis the details of the hardware I software organisation and the junction of the ILF block, and a proposition of a generic physical interface for ATM switches. Ibis work started in March 1996. and lasted about two years and half.
