Carrier Pre-Select Meeting BT Systems Interface Roadmap Graham Crane 18th September 2007

Cautionary Statement BT's 21st Century Network is still in the process of development and the subject of consultation. The information in this presentation may be subject to change' The purpose of this session is to cover: Background to the Workshop Scope & Objectives of the Day Agenda Mention the voting & texting

21CN Systems Architecture Roadmap & Example Interface Contents/Agenda 21CN Systems Architecture Roadmap & Example Interface Detailed documents / Further Information Enabling the eMarket - Detail 1. Future Industry model needs standards for processes, data & technology Moving to automated multi-service multi-supplier industry Need to move from multiple incompatible gateways, data and processes to fewer standard product agnostic data, gateways and processes 2. Consult(21) on future gateways Agree principles & capture requirements for future gateways Roadmap to consult on changes 3. NICC to agree standards Agree standards, best practice & governance Builds on existing work like EMP & consutl21 Takes account of any existing UK or international standards Update with feedback from real projects and capability development 4. Engagement with real projects & stakeholders Not just shelf-ware use on real projects, eg WBBC, BTW & Openreach gateways Engagement across BT and CPs, eg 21CN, 21CCE, Industry Forums, LoBs, 1IT, product teams, etc 5. Utilises & enables capabilities, reuse and agile working Standards & real projects used to create capabilities from reusable system and process components Capabilities exposed via Service Development Tool Kits (SDK) being developed in web21C programme Agile working techniques, hothouses, etc used and included in best practice 6. Industry forums can concentrate on commercials & requirements Delivery through common capabilities enabled by NICC standards 7. Continuous improvement By reviewing and aligning standards, real projects and capabilities

BT’s Platform Architecture – The Matrix Systems Investment and development for 21CN is aligned to a common architecture – we call it the “matrix architecture” The architecture defines the systems into 14 platform areas covering discrete functions It separates customer, service & network into layers across defined application interfaces It supports both new and old networks & services It is designed to protect our customers from underlying technology changes & allow them to embrace 21CN facilities as they choose 21CN (& implementing the “Undertakings”) are accelerating BTs transformation of systems throughout the architecture, but today we will concentrate on changes that impact you the customers, ie The collaboration platform

Raise/modify/cease Order Example of new Systems Interfaces – based on Wholesale Broadband Connect (WBC) CP Systems Customer Services XML BTWholesale Portal B2B Gateway Service Availability Raise/modify/cease Order Diagnostics Raise Fault CRM (OneSiebel)

Strategic Changes – WBC Example Our vision and how it will impact CPs More interactive B2B interface – no longer need to poll for responses, responses to pushed back by BTW Improving Scalability and Resiliency of the B2B Gateway – deploying a B2B gateway with greater scalability and resilience Greater consistency of interfaces – Provision and fault B2B interfaces currently use different technology. Provision interface to use same technology as current Fault interface for WBC Consistent experience across BT Products – similar B2B interface as is used for Openreach products SMPF/MPF Updating your interface with us - to use more up to date technology – e.g. using later versions of Siebel, browser-based client -no client deployment needed. Consistent across UK Industry – Aligned with Consult21 & NICC B2B
