Networks are becoming extremely complex. Operators have to mix and manage more and more technologies, including Fiber To The X (FTTx), IP, and Passive Optical Networks, in order to support the rush of new services, such as Triple Play, Voice over IP (VoIP), IP-TV, and Metro Ethernet. As a result, the need for a planning and engineering system that can support any network, any technology, and any type of equipment right down to the individual glass fiber is critical. It is the key to knowing where customers are located, linking them to the network, and efficiently managing the quality of converged services and find the most efficient way to fulfill the service requests in the overall NGOSS landscape. As a central data repository with the ability to track current, historical, and planned inventory and layouts, GDi OSS solutions facilitates data flow between Operations Support Systems (OSSs) and across functional areas. The result: Up-to-date data views are accessible not only to engineers, but also to strategic planning, sales and marketing organizations, field crews, call-before-you-dig centers, Web users, and management. Better collaboration and real-time data sharing can lead to major improvements in flow through provisioning, service assurance, procurement, and workforce management. GDi new generation operations support systems include business operations and network development and operations products and solutions for fulfillment and assurance, network lifecycle management and QoS.
