CP input used to shape BT’s thinking on:

•Future Voice Services

•BTs wider Deployment Strategy



change

Workshop Ethos & Approach

CPs are being consulted ahead of any formal decision by BT to help shape BT plans

Strawman approach to aid discussion on pro’s and con’s on options available

Recognise and acknowledge different CP needs

Guided by the key principles that BT outlined the last Steering Board

Deployment Strategy:Approach and Key Principles & responses to feedback

Ian StirratDirector, 21CN Planning & Performance

BT Design



change

Overall 21CN Approach and Key PrinciplesOverall objective unchanged:

The delivery of a service independent core infrastructure that will enable services to be differentiated through the flexibility, control and intelligence that software can provide

We will:

•look to deliver new services first, in advance of replicating existing services

•protect and enhance customer experience

•provide extended periods for voluntary customer upgrades to these new services, before moving to a technology migration of remaining customers

•build an open global and real-time platform on which new software services can be co-created with BT, or developed directly by our customers and third parties



change

Immediate Activity Areas

Deliver new Data and Broadband products over a rapidly accelerating 21CN infrastructure

Pathfinder

Bedlinog experience has been valuable Various service issues identified and resolved

Restart when Customer Experience optimised: Software upgrades loaded before more DLEs loaded

Gain further Customer Experience feedback: Validate Upgrade processes as new voice and other services are

launched

21CN Performance with larger volumes

Complete migration of both an AXE10 and System X

Migration process and procedures

Learning from full network configurations & Operational support learning

Review scale and scope of Pathfinder subject to Voice approach

Creating a new voice services framework:the balancing act

Consistency & ubiquity of end user services

Enable Innovation & Differentiation to end

users

High degree of control over the end

user service

Optimising & integrating system &

process devt roadmaps Access all or key segments of end

users

Exploit existing/NGN networks



change

Our Collective Opportunity

To collaboratively develop a new framework for the NGN world that:

Balances the needs of all CPs

Enables BT to fulfil its obligations

Create business opportunities

Drives innovation to meet the evolving needs of consumer and business end users

Builds confidence ahead of any network migrations

We aim to conclude the analysis and share our proposed approach by March 2008

Today is a great opportunity for us all to fine tune our shared insights and understandings



change

The journey to create the new framework & your input1. What are the key attributes of the technical architecture necessary to support

future voice services and the differing needs of UK CPs? What are CPs future voice capability needs that need to be satisfied by BT’s wholesale capabilities?

2. What are the key features/services/attributes of future voice services for both business and consumer end users?

3. What are the enablers which would make it attractive for you and your end user base to voluntarily migrate to those future voice services?

4. What are you looking for in BT’s Deployment Strategy Plan to give you confidence in the achievability of its proposed future voice approach?

Early migration

What will enable you to migrate 80% of your end users to the new

network (core voice?)

National Migration

What will enable you to migrate the remaining 20% of

your end users to the new network (“core plus” voice?)



change

Moving forward today:We would like to explore 3 broad themes

• How quickly do we want to embrace the opportunities and challenges of this brave new world ?

• How do we create and sustain differentiation?

• How do we plan and manage the transition?

•CP has their own Call Server.•They look to BT for virtual analogue lines•Access to these lines (on BT’s MSAN’s) could be either at the SIP Proxy level or at a lower level “Virtual Line Control” level (e.g. access to switch hook, digit-at-a-time)

•CP is a “SP” with account control for customer, and looks to BT for all network infrastructure including Call Server functions

How do we plan and manage the transition ?

national migration

Emulate current world

Create new basic voice service “80% of all end users use 20% of features”

What opportunities does this create?

What drives the CP decision making process for early

migration?

BT needs to innovate to meet it obligations in new way?

Opportunity for CPs to innovate to meet needs of specific market segments?

BT emulates some current services on 21CN?
