Abstract

: This paper presents a functional model simulator for broadband integrated services digital networks, based on requirements which fit within the objectives of RACE- MAGIC project. The first software simulator, written in Erlang, is an ISUP (ISDN User Part) state machine implementation, designed for measuring the performances of interworking of signalling between B-ISDN and the existing N-ISDN. The second software simulator represents a proposal for a MAGIC Functional Model implementation, using Erlang facilities for a rapid prototyping of a robust system. The future global telecommunications network should be able to understand all of terminals requirements, to negotiate the services and the resources to be offered and finally to have an adaptive behaviour. 1 INTRODUCTION
