EBC Solution – Changes to Routing Plans

• The Contract

• Prov Manual

• “Forms” required for the exchange of information

• Appendix 24 shows the Routing Plans


EBC Solution – What we do now with Routing Plans

• Routing of traffic to the POC

• Agreed with the TAM

• Data Management Amendment


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


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 – Routing Plan Database (RPD) System

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


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


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

•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

EBC Solution – EBC Modifications Summary

Routing PlansThese show agreed routing arrangements

DMAsThese effectively tell BT to put Routing Plans into effect

DatesThese 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


EBC Workshop

EBC Solution & NTS


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.


NTS: using EBC Evolution

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


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


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.


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.


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.


EBC Workshop

• Duplicate numbers EBC/CPL – different Operators

• Oftel and BT number range data synchronisation

• Historical CPL data on web site

• CPL Guidance

• Process document for the CPL

• Relationship between bill references and BT products


Completed and Planned Activities

1. Audit of number ranges

2. Timeliness of updates
