Abstract :
Powerful computer techniques and sophisticated measurement technology have been applied to local distribution networks by the 4TEL Automated Subscriber Line Test System. It provides PTT´s and telephone companies with a total solution to the problems of improving quality of service and reducing costs. The main features of routine testing, line testing, fault location, and special diagnostic testing are discussed together with a description of the technology, system architecture, enhanced features, and the potential for system evolution.
