Abstract :
The trends in electronic access systems and related technologies are reviewed. Such new features as SONET (synchronous optical network) feeder, multiservice line cards, remote testing, and bandwidth management are described. The features described will allow telephone companies to provide present and future services needed by the business community with lower costs, better performance, and faster response than ever before. The use of high-bandwidth optical feeder links extends the performance and capacity benefits of digital fiber systems to the business premises
