Independent CSPs. Independent CSPs legacy selective routers (LSR) can be honed to the LNG. Per customer request, the LNG design provides the interface for other service providers, such as Frontier, to enter the Arizona ESInet. The originating call can be from a legacy network or IP enabled network. West and CENTURYLINK encourage the direct connection of CSPs to the LNGs; however, this is not in scope of this project. Timing can depend on the Carriers, and on factors not under West or CENTURYLINK’s control. CENTURYLINK acknowledges the customer’s desire to allow wireless CSPs to direct connect during Phase One of the project. Allowing CSPs to direct connect during Phase One implementation brings on new project risks and will take additional planning and coordination to accomplish. This would include, but not be limited to: Negotiation of Interconnect agreements Determining costs for interconnection Solution Design Solution Implementation Solution Testing CENTURYLINK and customer will evaluate any requests for direct wireless CSP connection after the first successful Phase One PSAP migration. In this evaluation, CENTURYLINK and customer will determine project risks from the extra efforts required for wireless CSP interconnection. If both parties agree that the inclusion of direct wireless CSP interconnection to the i3 network poises low risk to a successful Phase One deployment, then such interconnection will be allowed. If, at any time after including wireless CSP interconnection, it is determined that successful deployment of Phase One is in jeopardy, CENTURYLINK may delay wireless CSP interconnection at its discretion. If it is determined that inclusion of direct wireless CSP interconnection to the i3 network poises to high of a risk to include in Phase One deployment, CENTURYLINK and customer can complete all planning required during Phase One deployment so that implementation of direct wireless CSP interconnection to the i3 network can commence at an agreed date following Phase One deployment.
