14. www.btwholesale.com NTS: withdrawal of NCD methodology and change to INCA/CLI Colin Rochester Later this year, as a result of an OfCom direction (October 2004), CPs will need to use EBC data to bill BT for NTS traffic they terminate. This change effects all CPs and this presentation gives an overview of these changes and the reason for them.

15. NTS: current interconnect charging CPs charge BT for termination of NTS traffic using: 1. “network charge differential” (NCD) method NCD methodology based on nos. of POC that your company has with BT NCDs were introduced as an expedient in 2001 2.INCA/CLI to determine the BT retention Currently INCA/CLI method uses the CLI to determine the EBC chargeband OfCom stated that the ‘NCD method must be withdrawn, and the CLI method changed to one acceptable to all CPs’October2004)

16. NCDs

17. INCA/CLI - current

18. Issues with existing INCA/CLI Network-selected POC used by EBC, rather than that requested by CPs IA, CPS and GNP export, in reality transit traffic, look like a BT-originated call BT line – CPS operator – BT transit – NTS operator The NTS operator sees the CLI in BT range so charges the call as BT originated TCPs cannot verify the TWIX on invoice for transit calls they receive (09A report) A TCP does not want to have to wait up to four months to get the benefit of an additional POC in EBC charging data

19. New INCA/CLI – billing regime (1)EBC created monthly to address timeliness issue (2)BT to supply two new EBC data files to identify retention as that appropriate to POC agreed in routeing plans (3)BT to supply new monthly “transit statistics” file provided to CPs to both allow TWIX verification and also to “adjust” apparent CLI-based BT- originated volumes to transit (4)New OCP retention charge band (single tandem) (5)TCPs provide a monthly adjustment (6)Impact to CPL (7)One methodology not two

20. New INCA/CLI

21. Summary Billing Changes for CP (1)Derive retention (BT-originated or OCP) from EBC data and bill BT for the month (2)Use the transit data to “convert” relevant BT-originated retention and re- calculate the bill, applying the difference as an adjustment (positive or negative) to the subsequent bill

22. Headline Summary OfCom direction October 2004 to switch off NCDs and introduce mandatory new INCA/CLI BT to provide new data files (EBC and transit statistics) to TCPs to support new methodology Key Customer Benefits Monthly EBC Ability to check Transit/BT originated charges EBC Based on customer data One methodology not two

23. Customer Actions TCPs need to load new data files to bill BT – this is not just a case of using EBC for bill verification BT to provide data for use in CP testing Summer 2005 BT has invited CPs to technical workshop 7 th February 2005, register and find out more Questions?
