Bandwidth scalability refers to the ability to allocate network and switching bandwidth flexibly to DSL users. In some service models a high degree of statistical multiplexing may be required, while in others the full DSL rate may be desired for each and every loop. The issue of efficient and scaleable operations support is perhaps the most critical area of the scalability problem, and the one most frequently overlooked. The solution lies in planning operations, network and services management from the very beginning to ensure that scaleable OAM models are in place before demand and deployment volume outstrip the ability to offer services cost-effectively. A single Hi-FOCuS system supports from eight lines up to 120 ADSL lines, and with four additional shelves can concentrate up to 568 ADSL lines over one ATM network.
FractalLink architecture maintains the required quality of service for each ADSL line.
Hi-FOCuS provides four Qualities of Service levels including traffic shaping in the upstream and downstream. This gives Hi-FOCuS the ability to deliver business quality services over DSL technology and enables all network service providers to address the diverse networking needs of a wide range of business customers, including large corporations with branch offices, SME, home offices and telecommuters. Traffic management - Providing an extensive and effective set of traffic management features that can be used to optimize statistical multiplexing gains, as well as to maximize uplink utilization. Service management - Creating a comprehensive service management that streamlines workflow, automates the provisioning process, and minimizes operation costs as the network grows.
