  3. Agenda • 10.00 Arrive & Coffee • 10.30 Welcome • 10.35 EBC Solution - Routing Plan Database • 11.20 EBC Solution - New Files • 12.05 Break • 12.20 EBC Solution & NTS • 12.50 EBC related activities • 13.30 Summary & Close • 13.45 Lunch

  4. EBC Workshop EBC Solution – Routing Plan Database

  5. EBC Solution – Changes to Routing Plans • The Contract • Prov Manual • “Forms” required for the exchange of information • Appendix 24 shows the Routing Plans

  6. EBC Solution – What we do now with Routing Plans • Routing of traffic to the POC • Agreed with the TAM • Data Management Amendment

  7. EBC Solution – Routing Plan manual activities • Not everyone is skilled in using spreadsheets • A consistent format is not always used • Human errors • Incorrect information • Ambiguous • Dates are not shown

  8. EBC Solution – What do we need ? • We need a system with…… • A uniform presentation and feel • Ease of use • Accessibility • Validation of information • DMA dates

  9. EBC Solution – Routing Plan Database (RPD) System • Routing Plan Database ( RPD )

  10. EBC Solution – Routing Plan Database (RPD) System • Benefits • Improved production and change control • Storage on a centralised date-stamped database • Replace spreadsheets for Ingress Routing Plans • Web-based interface • Opportunity to track changes • Provide agreed Exit POC information to the EBC system

  11. Data Validation TAM Fault Reception Read-Only Routing Plans Operator Routing Plan Database Intranet Network Implementation DMA Reception BT Wholesale Portal EBC Solution - Routing Plan Database (RPD) System - Interfaces

  12. EBC Solution - Routing Plan Database (RPD) System – Stages Initiated Submitted Rework Data Validation Agreed Raised Implemented

  13. EBC Solution - Routing Plan Database (RPD) System – Data entry • Look & Feel of the data entry will be similar to that of the existing spread sheets • Drop down lists will be provided to simplify choices • Validation will be provided where appropriate • On-line help will be provided

  14. EBC Solution - Routing Plan Database (RPD) System – Features • Routing Plan changes will be tracked • Routing Plan information will be provided to BT Fault Reception to aid network problem investigation • Automatic notification will be provided to the Operator and the TAM at key stage

  15. EBC Solution - Routing Plan Database (RPD) System – Change • Change in the current Routing Plan process • You will have to change how you submit Routing Plans • BT will have to change how we process the Routing Plans • Getting your Routing Plan requirements implemented on the BT network will be much improved • Using the DMA date stamps will improve the alignment of charging dates for EBC

  16. EBC Workshop EBC Solution – New Files

  17. EBC Solution – Routing Plans • Routing Plans and EBC • Operator issues from previous workshops • Ingress Points of Connection • Direct Feed from Routing Plans Database System • Relationship with BT PSTN Design • Visibility for Operators • Dates

  18. EBC Solution – Operators’ Perspective • Alignment of agreed Routing Plans and EBC charges • Charges that are more predictable • Closer alignment of EBC and NIPP • Clarity of how Number Ranges and Switches map to charges • Operators optimise routing with BT based on EBC

  19. EBC EBC Solution – System Relationships

  24. EBC Solution - Network Description & NIPP • BT’s Network Description provides: • High Level description, including outline planned changes • Operators access and download BT’s network description from: • http://www.btwholesale.com/interconnect2bt/network_information/network_description • NIPP provides • Greater detail of planned changes including detailed data files • Details of traffic types that can be exchanged at different types of POI • Registered users can access NIPP at • http://www.btwholesale.com/index.jsp

  25. EBC Solution– Two New Files • Existing files will continue • BT Wholesale will publish two additional files: • A file showing switch to switch to EBC charge bands • Used for planning where to connect • Little variation between matrix builds • A file showing EBC Charge Bands against valid number blocks • Used for planning where to pass traffic • Non-Retarded Number Ranges

  32. EBC Solution – EBC Modifications Summary • Routing Plans • These show agreed routing arrangements • DMAs • These effectively tell BT to put Routing Plans into effect • Dates • These are needed for any system that is going to feed into billing EBC will be modified to use the dates built into Routing Plans and DMAs from Summer 2004

  33. EBC Workshop EBC Solution & NTS

  34. EBC Evolution and NTS: INCA/CLI proposal • BT’s proposal (included in the response to the Oftel NTS con doc) for per-call EBC charging of NTS traffic is based on EBC evolution principles: exit POCs used for charging will be identified from the routing plans.

  35. EBC Evolution NTS Two new “planning” files RPD to identify exit POCs Planning files used to determine where to collect NTS traffic at least cost, update routing plans RPD to identify exit POCs Two new NTS charging files NTS: using EBC Evolution

  36. INCA/CLI NTS and EBC Evolution, detail • This presentation deals solely with identification of EBC charge bands • OLO-BT-OLO Transit, representation as currently, change to method of identifying exit POC. • EBC charge band is cheapest connectivity path from entry POC to the agreed exit POC identified in the routing plans for that entry POC and the destination number range

  37. INCA/CLI NTS: BT-OLO traffic • Two new EBC Files: • Destination number, linking key • Origin number, linking key, charge band • The charge band represents the retention to be used when calculating the BT outpayment. • If CLI in BT range, a BT-originated charge band will identified; exit POC used from routing plans • If CLI is in a non-BT range a single “transit” charge band will be identified, corresponding to ONO retention.

  38. BT-OLO NTS: TWIX verification • GenIUS will provide TNOs with data showing for incoming-to-BT NTS transit traffic, amongst other things: • TNO NTS range • Entry POC • Time period • Number of calls starting in this time period • Number of minutes in this time period • TNOs may use the entry POC and NTS range with the “normal” EBC matrix to verify the TWIX charged by BT.

  39. NTS and timeliness of POC inclusion in EBC • The use of the Routing Plan System reduces EBC build time. • Two new EBC files should reduce OLO EBC timescales. • In order to reduce time lag for POC changes to be reflected in charging data BT proposes a monthly EBC as this is now practical.
