13. PPC Radial Distance Validation

14. Objectives Of Circuit Revenue Assurance Board. (CRAB) Validate and cleanse the radial distances for circuit and billing records. Improve accuracy in the customer, Order handling, Network, and invoicing data. Web based Data Quality Monitor (One Truth Database) Data stewarding on an on-going basis. Improve customer satisfaction. Report progress to the Revenue Assurance Board on a monthly basis until project completion. The project will deliver these objectives and be completed by 30 th June

15. Migration of RPC to PPC –Migration Tool had a rounding error –didn't always pick the correct serving exch –Issue with grid references – leading 0 Introduction of Tier One Pricing –B end Post codes missing or inaccurate Errors in data feeds used by the TODD tool. –The odd 1141 codes duplicated or transposed. –Missing post codes in our Customer Service System –Customer Management Center process Inconsistent Trunk and Terminating field layout PPC Radial Distance – Issues

16. PPC Radial Distance - Issues Bill Validation Its very complicated No Clear written Industry Process Missing post codes in the Exchange Name Postcode file. Customers using OLD Post Office Address File (PAF) Customers not able to provide or validate their own B ends

17. PPC Radial Distance- Bulk Cleanse Validation Pilot –Send sample of changes to each Customer –Customer to Validate the sample and agree –BT to then Update its systems Remaining –Send all changes to each Customer –Customer to Validate and agree –BT to then Update its systems Billing Corrections –Readjusting back to when tier 1 pricing was introduced.

18. PPC Radial Distance – By June 05 Completed the Bulk Cleanse Clear written Industry Process issued –True Serving Exch – Exchange Name Postcode file. –Nearest Serving Exch –Supplementary Post Code List –Grid Reference – centered- current Post Office Address File –Matching Point of Handover (PoH)- grandfathered PDH RPC / PPC Migration tool Fixed Customers validating B end Post codes TODD - Data feed corrected. Provision System corrected - Screens Improving Training in Customer Management Centre Radial Distance “One Truth” tool to hold the gains – June 05

19. PPC Radial Distance – Since July 05 8000 Circuits Issued since Jan 05 required Validation New problem with “SEAM” Data effecting Todd and the PSEF file. –Complex Fix –Delayed due to flooding in India. –Finally fixed in Sep 05 Other Issues resolved Complete Re-Validation of all Radial Distances Mop Up in October 05

20. PPC Radial Distance – CRAB Today All Radial Distances Now Validated as Per the Tier 1 Pricing Directive. All Operational Support Systems Updated No outstanding Systems fix’s Ongoing Data Stewarding Billing Corrections –Readjusting back New Radial Distance V2 tool to hold the gains – Dec 05.

25. PPC Radial Distance – CRAB Lessons learnt Post implementation review Communications –Industry Briefings –Industry Forums –SPOC –Wholesale Billing Team –Billing Work Shops (UKCTA) Fix all the OSS Systems - Then Run Bulk Cleanse

26. PPC Radial Distance – Ongoing Product Line Issues Requirement for One PSEF File ? –PSEF- 90% of Postcodes –Supplementary PSEF 10% of Postcodes. ( No Postcode, No PSTN Service) –P/L is Looking at this proposal, System design, Costing etc –9 Month Development ? Supplementary PSEF File –Purpose is to capture Missing Postcodes not in the PSEF –Purpose is there to help Validate the Bill –Not Designed to hold Historical Postcodes –P/L is Looking at this Historical proposal, System design, Costing etc

27. PPC Radial Distance – Ongoing Product Line Issues PSEF File- additional Info –Based Currently on Telephony to Actual Serving Exchange to Post Code ( LLU Requirement) –Asked to also include Actual Private Circuit postcode to Serving Exchange. –P/L is Looking at this proposal, System design, Costing etc Other Considerations 21CN timing is a factor to be considered in for any new development requests The Grid Reference is the only way to guarantee 100% accuracy on radial distances
