EBC Solution –Routing Plan Database

• Contract

• Provisioning Manual

• Appendix 24

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

EBC Solution – Current Routing Plan Contents

• Spread sheet Routing Plans

• Operator details

• Number strings

• BT Switch Connections

• Catchment Areas

EBC Solution and Exit POCs

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

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

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

Use of Agreed Exit POCs, BT-originated

Processing logic for each traffic type originating from a BT DLE:

Is the DLE a POC?YES NO

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

Use of Agreed Exit POCs, transit

Processing logic for transit traffic at each BT tandem:

Is the tandem an Exit POC?

YES NO

Use the POC in the RoutingPlan for charging

Obtain EBC charge band from tandem to Agreed Exit POC

Identify the Agreed Exit POC from the

Routing Plan

Benefits

•Transparency

•CP control

•Predictability

•Simplification

EBC Solution and Timeline

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’.

EBC Solution and Two New Files

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

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

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
