By using a graphical user interface (GUI) screen, a network operator provides to subscribers service for automatically discovering the configuration management and network topology of Optical network units (ONU's) in a fiber loop carrier-curb system. When a host digital terminal (HDT) or optical network unit connected to a subscriber is added to a fiber loop carrier-curb (FLC-C) or fiber loop carrier-curb management system (FMS), the added network element is displayed on the graphic user interface screen as an icon in a designated position of a network topology. Conversely, when a network element (NE) is deleted from the management system, its corresponding icon is removed from the network topology. A star topology is used as the preferred network topology and configuration method in the present invention. When the star topology is displayed, the host digital terminal is located in the center of a concentric circle, surrounded by a maximum of 16 optical network unit's. Each optical network unit is connected to a host digital terminal and has its own assigned position in the star topology. The position of each optical network unit is determined from the configuration identification information of the optical network unit, which is automatically checked upon addition of the optical network unit to the management system. Using the identification information, the optical network unit automatically is placed in a designated position of the star topology.
