21CN – Key Milestones
2011
21CN
completes
Next generation broadband
available to >20m end users.
21CN migration substantially
complete
Next generation broadband available to >16m
end users. ~ 65% of broadband and ~50% of
PSTN lines migrated
2010
2009
2008
2007
2006
2005
2004
UK wide migration to 21CN begins. Next generation
broadband product available to ~50% of UK.
> 15% of PSTN lines migrated
~50% of UK broadband services delivered over 21CN
Strategic vendor contracts signed. UK migration plan announced.
Part of the IP/MPLS core network in place. Migration control centre established.
Comprehensive testing and trials. End user communications strategy enacted.
End user migration begins
Industry engagement via Consult21 gains pace. Strategic vendors announced.
First service launches based on reusable capabilities
BTs 21CN vision announced. Consult21 launched. Converged network architecture developed.
Voice transformation trial underway

New Era of NGN Regulation
Promoting Investment and Innovation
BT’s Undertakings offered in lieu of reference to
Competition Commission in September 2005
Regulation to be focused on bottlenecks
Incentive to invest in NGNs and Innovate
Expectation of reduced regulation downstream
Promote infrastructure-based competition
Benefits the consumers, operators and UK economy
Incumbent to compete fairly on a level playing field
Creating a climate of confidence for
infrastructure Competition, Investment and
Innovation
Colombo, Sri Lanka, 7-10 April 2009
11
Regulatory Context in the UK
Ex-ante regulation
Applies to defined markets where a communication
provider has Significant Market Power (SMP)
Provision of network access/interconnect, nondiscrimination, cost-oriented prices, etc.
BT’s Undertakings – NGN specific section
No foreclosure of network access without
consultation
Charges to be based on efficient network design
Network access to be provided on Equivalence basis
Industry group to agree transition to NGN
interconnect
Compensation arrangements
Colombo, Sri Lanka, 7-10 April 2009
12
Regulation and NGN – Key Issues
Investment – “Regulatory certainty”
NGNs are driven (in part) by cost savings
Investment requires demonstrable shareholder value
Regulators face a difficult challenge
No one can “build it and they will come” on revenue bet
NGNs/NGAs are disruptive to traditional boundaries
They challenge past regulatory assumptions
(e.g. thin & dispersed vs. fat & fewer interconnect, minutes
& miles vs. capacity & QOE)
Regulation needs to become simpler
Requires collaboration amongst incumbents, regulators and
Competitive communications providers.
Over regulation could restrict converged service innovation

BT’s Consulation Approach
Consult 21
Consult 21 launched Summer 2004
Largest voluntary consultation of its kind ever undertaken in our
industry 650 people from industry involved
Remit is open and transparent consultation with wholesale
customers (CPs)
Director recruited from a CP
10 Working Groups, including:
Product Migration from 20CN to 21CN
(E.g. PSTN Interconnect, Broadband, Ethernet)
21CN Migration Management
Communications
Commercial
Each WG has BT and Industry Co-Chairs
Industry Steering Board (Ofcom monitors)
All proceedings published on the Internet

Next Generation Broadband:
A bold vision for the UK
UK’s biggest super fast broadband investment: £1.5 bn
Accessible by up to 10 million homes by 2012
Range of speeds up to 100mbps: with >1,000mbps potential
Basis for nationwide demand led roll out
World’s most open super-fast network
Need for the barriers to investment being removed

Removing the barriers to investment
We need to have…
the chance to earn a fair return if investment is
successful
principle based regulation that avoids red tape
removal of outdated rules, such as having to
deploy copper cables in parallel to fibre
assurance that other UK companies will
wholesale their fibre services just like we will
freedom from responsibility for other operators’
past investment
