21CN – Pathfinder programme overview
Dave D’Arcy & Bob Corner
BT Wholesale
The dates and other information about BT's 21CN programme in this presentation are based on the best information currently available. As in any programme of this size and complexity, they may be subject to change
2
Introduction
• The purpose of this presentation is to explain the 21CN Pathfinder approach:– What is Pathfinder and why are we doing it– Approach to Pathfinder and timescales– The consultation approach– What’s coming next
• The intended audience is:– Communication providers (CPs) and resellers.

How did we get here?
• On Tuesday 28 November 2006, BT made communications history when the transfer of the first customer lines to its new next generation network began at Wick in the Vale of Glamorgan.
• To reach this important milestone BT has already:– re-built around ten per cent of the UK's core national
communications infrastructure
– installed 21CN equipment at over 100 sites across the UK
– laid more than 2,300 kilometres of new fibre optic cable in South Wales
– invested more than 1,500 man years in developing new IT systems to support the new network.

Today
A single network that’s physically simpler and more reliable than our existing, complex infrastructure could ever be.
Up to 50 per cent fewer components in terms of switches, hubs, routers and suchlike.
We will be able to deliver the next generation of converged services faster, more efficiently and more cost-effectively than ever before.

Consult21 Objectives
•• Ensure industry is aware of the 21CN vision and BT’s progress towards it.
•• Achieve a shared understanding with Industry.
•• Ensure industry has an opportunity to input to 21CN development.

What is Pathfinder?
• A chance to start small & build to a scaleable national solution (in phases).
• A chance to start early, prove & then review before National Migration from 2008.
• Cardiff = a good mix of– Business / Residential
– City / Rural
– POTS / ISDN2 / ISDN30 / BB
– Approx 1/80th of the UK
10
Approach to Pathfinder
• A comprehensive trial and testing programme is underway.
• More than half a million tests were conducted in the countdown to the first phase of end user migration.
• BT will migrate around 350,000 customer lines in the South Wales area, including many served by other telephone and internet service providers and mobile operators.
• Cardiff and the surrounding area was chosen for the first stage of 21CN implementation because the area's demographics are also representative of the UK market and critically, BT's customer base.
11
Approach to Pathfinder
• BT will be replacing nine digital local exchanges in the area and each one will take approximately 20,000 man hours to complete - the equivalent of almost 94 years for one of our skilled engineers to complete on his/her own!
• BT estimates 1,100 man days are required for operational readiness and provision of the necessary operational links for communications providers' migration in this area.
• The experience and customer feedback from the first mass customer migration project will help BT finalise plans to roll out
12
Approach to Pathfinder
There are three phases to the Cardiff upgrade.
• The first, which involves upgrading voice services to around 1,200 customer lines, kicked off in November 2006.
• Phase two is planned for July and August 2007, when a further 58,000 lines will be upgraded.
• Finally, by the end of 2007, we will have upgraded all 350,000 PSTN customer lines in Cardiff and the surrounding area.
13
Pathfinder is Focusing on -
• Migrating 350,000 customer lines
• Replacing 9 digital local exchanges
• Installing new equipment in over 70 technical centres

Customer migration boundary
The UK Network build is being built in parallel with Pathfinder (over 400 sites), in readiness for migration at the end of Pathfinder.
In the Pathfinder area, we will be deploying MSANs at 51 sites, 3 Metro Nodes and 1 Core I-node, together with its supporting 21CN transmission network in a further 20 sites.

Consultation Approach
Consult Line Migration
eg Pathfinder Review
• Review TE methods and migration processes
• Assess the impact
• On end users
• BAU fulfilment /assurance processes
• Identify information and tools required to manage these impacts
• BT carry out a carefully designed migration in line with a published plan
• CP’s manage their customers through the migration in line with policies they have created
• BT/CPs verify the migration process was carried out as expected
• BT/CPs identify gaps
• CP’s to review their processes/policies
• CP’s identify any refinements to their processes/policies
National Migration
18
Organisational Learning
• We don’t expect everything to run smoothly throughout Pathfinder!
• We’d much rather identify the problems, issues and bottlenecks now than during National Migration.
• After each phase of Pathfinder we will review what we did and how we did it.
• BT will conduct these reviews both internally and with CPs.
• BT will use the output of these reviews to improve the processes that we follow in subsequent migrations where possible.
