A new optical access system based on the synchronous transfer mode - passive double star system has been developed to provide high-speed LAN-like access. It uses a shared-band method that enables multiple users to efficiently share a single bandwidth of up to 10 Mb/s and a grouping function that divides the access network into several logical networks, each of which can provide a virtual LAN to users. This paper describes an information model and a framework for configuration management and fault management and discusses the requirements for element management, which involves data-link establishment, logical group management, and testing. Element management mainly requires appropriate remote handling on data cards installed in each optical network unit on user premises. A method is proposed that satisfies these requirements. With this method, the element operations system can provide the required operational functionality.
