9. http://www.btwholesale.comhttp://www.btwholesale.com 9 Communication with Operators Today’s workshop Syndicate session today for way forward Website for reference of key documents Linkage to NTS focus group

10. http://www.btwholesale.com http://www.btwholesale.com 10 NTS Issues Verification of bills NTS Focus Group/New solution

11. http://www.btwholesale.com http://www.btwholesale.com 11 Current Process Calls Terminating on BT Geographic Numbers BT originated IA/CPS/118DQ BT originated NTS Transit

12. http://www.btwholesale.com http://www.btwholesale.com 12 New Solution-Agreed Exit POC Need for greater transparency, how EBC works, what it is Instead of deriving Exit POCs the new solution will use Exit POCs requested and agreed in Routeing Plans Maintain principle of least cost connectivity path Improved Routeing Plan process Changes to EBC algorithms

13. http://www.btwholesale.com http://www.btwholesale.com 13 New Solution - Agreed Exit POCs (AEPs) As now, Operators and BT agree Routeing Plans As now, Routeing Plans show catchment area, number range and BT switch passing calls to OLOs As now, Operators raise DMAs (formal requests for BT to implement routeing plans) Need for change Routeing plans currently do not show: Date stamp If/when DMA has been raised by the Operator When DMA has been implemented by BT Hence, Routeing Plans currently show intended possible future routeing in the BT network rather than actual routeing Therefore not currently suitable for use in charging

14. http://www.btwholesale.com http://www.btwholesale.com 14 Changes to Routeing Plans Future Routeing Plans and Process need to identify and store: Date submitted by Operator Date agreed with BT Technical Account Manager Date DMA raised Date DMA implemented

15. http://www.btwholesale.com http://www.btwholesale.com 15 EBC use of Agreed Exit POCs data Processing logic for each traffic type for each BT DLE: Is the DLE a POC? YESNO Use the POC for charging Select Tandem Exit POC from Routeing Plan Obtain EBC charge band from DLE to Agreed Exit POC

20. http://www.btwholesale.com http://www.btwholesale.com 20 EBC use of Agreed Exit POCs data Processing logic for transit traffic at each BT tandem: Is the tandem an Exit POC? YESNO Use the POC in the Routeing Plan for charging Obtain EBC charge band from tandem to Agreed Exit POC Select the tandem Exit POC from Routeing Plan

21. http://www.btwholesale.com http://www.btwholesale.com 21 Benefits Transparency of the EBC AEP process Receiving Operator determines the AEP for charging Operators able to predict charges when planning routeings Removal of EBC data relating to disallowed traffic routeing Simplification of build process and maintenance NTS Opportunity to standardise charging to include NTS NTS Focus Group considering Agreed Exit POCs Process for reflecting POC changes improved

22. http://www.btwholesale.com http://www.btwholesale.com 22 Syndicate Sessions Two syndicate sessions: Nominated presenters from each syndicate Red – Identify areas where further explanation would be helpful and identify any areas of concern with the new solution Green – Identify means for your continued involvement and the communication of BT’s development of the solution Last 10 minutes of each session: ‘What are your requirements for a Web Based EBC Analysis Tool?’ ‘What benefits would this bring you and how much would you be prepared to pay for it?’

23. http://www.btwholesale.com http://www.btwholesale.com 23 Summary & Close BT has scoped an EBC Solution EBC Solution explained and discussed Routeing Plans are integral to Solution New processes are being developed and will be documented BT will take away feedback from today’s workshop and develop further processes and communications Thanks …. and Lunch arrangements
