Input requirements needed to produce an operational profile for a new telecommunications system

This paper describes our practical experiences in developing an operational profile for a telecommunications system given little existing knowledge about the maintenance/provisioning process and the system´s environment. The specific system under test is a high availability, real-time system used to provision, maintain, and forecast network hardware for AT&T´s emerging technologies. The system requirements needed to derive the various system operating modes, together with the modes´ operational profiles are discussed. We also demonstrate how reliability objectives and failure intensity objectives can be defined and subsequently tested under different automated test scenarios for these different system modes
