Understand demand, Design viable network options, Estimate network costs, Understand existing broadband coverage and ultimately, Explore and assess potential support assumptions. Also, across the architecture are a set of options and toggles that provide users with the opportunity to explore a number of different inputs and support scenarios. CACM also includes a reporting function that provides users with a variety of outcome reports and a variety of audit reports. A schematic of CACM’s five architectural components and related functions follows. Abbreviations and terms used in the schematic are explained throughout the Methodology. For example, CQLL refers to the CostQuest LandLine process whereby demand points are connected (modeled) back to a known Central Office and CQMM refers to the CostQuest MiddleMile process whereby Central Office locations are connected (modeled) to a location where Internet peering can occur . POI refers to a Point of Interconnection, otherwise known as a Central Office. A third view (Figure 15) is presented in Appendix 5 and provides a more detailed view of how CACM sequentially processes inputs and develops reports.
