2. Agenda What are the datasets? and why they are important When are the datasets published? The different types of datasets available How can the information from the datasets be used? How to access the datasets Who to contact with queries and how to register for updates

3. Background The Service & Network availability datasets exist to provide up to date information about the current state of BT’s 21CN network and the products it support. Several different datasets have been constructed to show different views of the data such as Broadband service availability and Voice migration dates. The information is refreshed at the beginning of each month. The information can be found on a dedicated area on BTWholesale.com

4. When do we publish the Datasets? Published every month, 3 rd working day. Available via the BT Wholesale & Openreach portals Provides a 2 year rolling view –first six months, individual month view. –next 6 months split into two 3 month periods –next 12 months as a single period

5. The Datasets Network Inventory Datasets –The network inventory is one of the main pieces of information BT provides to CPs about its Network to assist CPs undertake investment planning taking into account use of Openreach and Wholesale obligatory products. –The network inventory comprises of about 30 datasets that reveal network location details, network topological details, numbering details, and network roll- out details relevant to obligatory products Service Availability Datasets –The Service Availability datasets identify the sites at which services supported on 21CN and the date from which they will be available. –Designed to enable CP’s to identify sites and service availability & migration to enabling their customer migration or availability of service. Service Availability datasets are updated every month. Network Inventory datasets tend to be standing data, updated as required.
