Abstract

The purpose of this paper is to present an efficient tool, as well as a new teaching method, using a symbolic concurrent programming language Erlang (hosted on a workstation running UNIX/DOS/Windows) for a telecommunications application. The aim is to realise a software simulator for the ISDN access, being an ISUP state machine implementation, but also the paper is focused on underlining the stages that a teaching course would have to address in order to generate, step by step, a rapid prototype. It can be useful to understand the mechanisms of a client/server architecture and a socket/port based inter-processes communication. Obviously the software simulator is a powerful instrument to verify the specific signalling protocols involved as well. 1 Introduc
