OS/DA. The OS/DA UNE is defined as: (a) any automatic or live assistance to a consumer to arrange for billing or completion, or both, of a telephone call (OS); and (b) a service that allows subscribers to retrieve telephone numbers of other subscribers (DA). In accordance with Rule 51.319(f), VERIZON will not provide OS/DA as a UNE when it offers customized routing. Where SPRINT provides its own OS/DA platform, SPRINT is required to route its OS/DA traffic to its platform over customized routing. Upon written request, VERIZON will provide SPRINT a list of Central Office Switches that can provide customized routing using line class codes or similar method (regardless of current capacity limitations). SPRINT will return a written list of these switches ranked in priority order. VERIZON will return to SPRINT a schedule for customized routing in the Central Office Switches with existing capabilities and capacity. In response to SPRINT’s written request, VERIZON will also provide SPRINT with applicable charges, and terms and conditions, for providing OS and DA, branding (such branding shall be provided consistent with Section 2.5 of the Resale Attachment to this Agreement), and customized routing. Subject to the above provisions, VERIZON will choose the method of implementing customized routing of OS/DA calls. When VERIZON offers customized routing to SPRINT, SPRINT will be responsible for the transport to route OS/DA traffic to the designated platform. If a dedicated transport UNE is used to route OS/DA traffic to the designated platform, SPRINT must purchase a trunk side port and establish a collocation arrangement in accordance with the Collocation Attachment. If the dedicated transport UNE used to route OS/DA traffic to the designated platform is ordered out of the applicable access tariff, no collocation arrangement or trunk side port is required.
