http://www.btwholesale.comhttp://www.btwholesale.com 37 EBC Solution and Exit POCs

http://www.btwholesale.com http://www.btwholesale.com 38 EBC & exit POCs: Current Process EBC currently uses a set of rules in conjunction with a list of exit POCs to derive the charge for: BT originated IA/CPS/118DQ Transit

http://www.btwholesale.com http://www.btwholesale.com 39 New Solution: Agreed Exit POC No change to charging for BT-terminated traffic or BT- originated NTS The new solution will use Exit POCs shown in the routing plan database Least cost connectivity path to get to the agreed exit POC Changes to EBC algorithms, but not the use of EBC data

http://www.btwholesale.com http://www.btwholesale.com 40 New Solution - Agreed Exit POCs (AEPs) Routing Plan data will directly drive EBC charge bands The Routing Plan data shows catchment area, number block and BT switch passing calls to CPs, e.g. Ipswich, 01473292, Ipswich Unit A The routing plan database will show: If/when DMA has been raised by the Operator Agreed date of change on DMA When DMA has been implemented by BT The exit POC for a given origin will be that agreed to be in place when the EBC data goes live

http://www.btwholesale.com http://www.btwholesale.com 41 Use of Agreed Exit POCs, BT-originated Processing logic for each traffic type originating from a BT DLE: Is the DLE a POC? YESNO Use the POC in the Routing Plan for charging Select Tandem to use as AEP from Routing Plan Obtain EBC charge band from DLE to Agreed Exit POC

http://www.btwholesale.com http://www.btwholesale.com 42 Use of Agreed Exit POCs, transit Processing logic for transit traffic at each BT tandem: Is the tandem an Exit POC? YESNO Use the POC in the Routing Plan for charging Obtain EBC charge band from tandem to Agreed Exit POC Identify the Agreed Exit POC from the Routing Plan

http://www.btwholesale.com http://www.btwholesale.com 43 Benefits Transparency CP control Predictability Simplification

http://www.btwholesale.com http://www.btwholesale.com 44 EBC Solution and Timeline

http://www.btwholesale.com http://www.btwholesale.com 45 EBC Solution - Timeline - DMAs EBC Matrix ‘Y’ Build Start Date EBC Matrix ‘Y’ Effective Date EBC Matrix ‘X’ Effective Date EBC Matrix ‘X’ Build Start Date If DMA ‘A’ Agreed Implementation Date is during this period, then changes will be included in Matrix ‘Y’. DMA ‘A’ may be raised during this period for inclusion in Matrix ‘Y’. If DMA ‘A’ Agreed Implementation Date is during this period, then changes will NOT be included in Matrix ‘Y’.

http://www.btwholesale.com http://www.btwholesale.com 46 EBC Solution and Two New Files

http://www.btwholesale.com http://www.btwholesale.com 47 New Files – The Drivers Alignment with agreed routing Charging predictability Enabling routing optimisation Need for enhancements: Shows only existing points of connect Retardation of number ranges Exchange mapping Non-contractual traffic Effort

http://www.btwholesale.com http://www.btwholesale.com 48 Two New Files A new file to assist CPs receiving traffic from BT A new file to assist CPs delivering traffic to BT Standard EBC file format Standard naming convention Standard header and trailers Comma-separated format data records

http://www.btwholesale.com http://www.btwholesale.com 49 File 1 – Receiving Traffic from BT A BT-switch-to-BT-switch matrix, with charge band Any traffic type Valid call routing scenarios E.g. a DLE origin would be shown against the following destinations: For BT-originated traffic, the DLE itself and all switches that could be Exit POCs For transit traffic, nothing Each data record will contain: origin exchange NNI, destination exchange NNI, EBC charge band Transit / Non-transit charge bands
