21CN - three key objectives
o Empower the customer with
control, choice and
flexibility like never before
including communications
from anywhere to any device
Speed to
market
o Offer exciting new services
Customer
experience and
empowerment
for customers faster than
before
o Reduce costs - expected to
amount to £1 billion ($1.8bn)
per annum by 2008/9

Drivers for 21CN
o Convergence
•
•
•
•
•
Fixed / Mobile
Service (work, home, business, bundles)
Computing / Telecoms
Voice / Data
Intelligence and OSS
o Pressure on traditional revenues causes Telco’s
By convergence, we mean the
ability to bring together our
capabilities and capacities in new
ways to make life better, simpler
and cheaper for customers. For
customers of all kinds it means a
more joined-up communications
experience.
Ben Verwaayen, BT CEO June
to diversify 2005
• ICT
• Mobile
• IPTV
o The internet leads to service and pricing expectations in the users
mind (online, immediate, anywhere, free)
o Pent up demand for increasing broadband speed
o Aggressive regulation and competition
ITU-T
ITU-T / ATIS Workshop “Next Generation Technology and

Las Vegas, 19-20 March 2006
21CN – it’s big and bold
o Not simply network
transformation - but a
radical overhaul of products,
systems, process … of BT’s
business
o Bigger annual investment
than is spent on UK’s
motorways and trunk roads
o A world first for a
telecommunications company

ITU-T / ATIS Workshop “Next Generation Technology and

Las Vegas, 19-20 March 2006
Early migration to NGN
o Huge logistic and technical challenges
o Full 21CN capability set not possible on day 1
o Timely down streaming of key standards is a
critical issue, requiring
• Alignment with strategic suppliers
• Working with other Telcos
• Key inputs to ITU-T, ETSI and ATIS standards

The ITU/ATIS Definition of NGN
o
o
o
o
o
o
o
o
o
o
o
o
o
o
Packet-based transfer
Separation of control functions among bearer capabilities, call/session, and
application/ service
Decoupling of service provision from network, and provision of open interfaces
Support for a wide range of services, applications and mechanisms based on
service building blocks (including real time/ streaming/ non-real time services and
multi-media)
Broadband capabilities with end-to-end QoS (Quality of Service)
Interworking with legacy networks via open interfaces
Generalized mobility
Access to different service providers, independent of any access or transport
technology.
A variety of identification schemes
Unified service characteristics for the same service as perceived by the user
Converged services between Fixed/Mobile
Independence of service-related functions from underlying transport technologies
Support of multiple last mile technologies
Compliant with all Regulatory requirements, for example concerning emergency
communications, security, privacy, and etc.

BT’s 21st Century Network (21CN)
o Aims to reduce cost, speed time to market for new services
o
o
o
o
o
o
o
and give the customer more control.
Radical plan to close down legacy networks (PSTN, Private
circuit, PDH, ATM FR etc).
MPLS core over meshed optical
Ethernet backhaul over CWDM
3GPP IMS intelligence
Multi-service access nodes (MSAN) for service access
Provides old and new services (e.g. PSTN replacement)
Current interconnect discussions around legacy PSTN and
PSTN over IP show complexity of the new interconnect issues.
Closely aligned to the ITU and ATIS definitions
ITU-T
ITU-T / ATIS Workshop “Next Generation Technology and
Standardization“
Las Vegas, 19-20 March 2006
21CN and Standards
o 21CN is predicated on standards for
• Network operators
• Equipment providers
• Service providers
o Global standards are vital for 21CN
• Enhanced customer choice & experience
• Uniting the telecoms and IT industry
• Network Interoperability
• Economies of scale

Progress towards NGN standards...
o ITU-T Focus Group on NGN complete and down
o
o
o
o
streaming begun in SG13
ATIS Focus Group on NGN
ETSI TISPAN working with 3GPP on intelligence and
control (IMS)
TeleManagement Forum (TMF) focusing future OSS
standards
Widespread agreement on the key principles
•

•
IP services
IMS intelligence / fixed-mobile convergence
MPLS core
Need for multiple access technologies
High level of agreement globally
ITU-T
ITU-T / ATIS Workshop “Next Generation Technology and

Las Vegas, 19-20 March 2006
Key issues
o Architecture
• Top level aligned but need it at all levels
• Need to include
— Wireless broadband
— IPTV
o Quality of Service
• How to achieve end-end, and across different NGNs?
o Interconnection
• Need for new business and technical models in the NGN
o OSS
• Still often the critical path in new service launch
• Critical for cost savings
• Link with TMF
o Applications
• Will drive demand and capability
ITU-T
ITU-T / ATIS Workshop “Next Generation Technology and

Las Vegas, 19-20 March 2006
What BT needs from ATIS and ITU-T
o Uphold a common definition of NGN
• Release strategy
• Consistent architecture
o Co-ordinate
• ATIS leads for North America
• Remove duplication
• Identify and fill any gaps
o ATIS
• Take the Focus Group work forward into Working Groups
o ITU-T
• Global set of Recommendations
• Built around ETSI TISPAN and ATIS standards
• Meet the needs of all regions
o Timely delivery of quality standards that BT can procure against
ITU-T
