Forward-looking statements ­caution advised

Certain statements in this presentation are forward-looking and are made in reliance on the safe harbour provisions of the US Private Securities Litigation Reform Act of 1995  These statements include, without limitation, those concerning: transformation of BT\'s networks; expected increased efficiencies, cost reductions and growing cash cost savings from 21CN; benefits to customers and industry of the 21CN programme, and convergence; anticipated investment in 21CN; and timescales for implementation of 21CN

Although BT believes that the expectations reflected in these forward-looking statements are reasonable, it can give no assurance that these expectations will prove to have been correct  Because these statements involve risks and uncertainties, actual results may differ materially from those expressed or implied by these forward-looking statements  

Factors that could cause differences between actual results and those implied by the forward-looking statements include, but are not limited to: material adverse changes in economic and financial markets conditions in the markets served by BT; future regulatory actions and conditions in BT’s operating areas; technological innovations; developments in the convergence of technologies; the anticipated benefits and advantages of new technologies, products and services, including broadband, not being realised; and general financial market conditions affecting BT\'s performance  BT undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise
Setting some context for 21CN
25+ million customers in the UK Residential
SMEs
Large corporates Regional
National Virtual CPs PSTN/ISDN
LLU
PPCs
IP/Ethernet VPNs
During the next 25 minutes I plan todiscuss:

Why BT is doing 21CN

An introduction to 21CN and the technology being deployed

The role of MPLS within 21CN

Some possible next steps
21CN -it’s big and bold
Not simply network transformation…a radical overhaul of BT’s business and systems
A world first for a telecommunications company
Delivering a step change in the way
industry creates and delivers services
21CN evolution

Ethernet for services, aggregation & backhaul

IP/MPLS for the core

Separation of services from the network

Enabling global delivery of next generation services from the converged core in the UK

First services in the UK = PSTN, Broadband and Ethernet
Current thinking No implementation assurances
21CN UK network architecture
Interconnects to other Comms
Providers Ethernet Ethernet Ethernet over NG-SDH over NG-SDH over WDM
Design based on stacked VLANs (S-Tag & C-Tag)
The MPLS core
Metro/Core PoP Metro/Core PoP
IP VPNs: PSTN signalling and

21CN Management VPNs
P PWE for Broadband to BRAS PSTN
P
To MSANs
BRAS MGW
RR IP/MPLS Core RR
Protocols: IPv4, OSPF, MPLS LDP and RSVP-TE
Virtualisation: IP VPNs (RFC4364), PWE3 (RFC3916)
QoS: 7 levels (6 user, 1 control)
Unicast
Two types of resilience being implemented

Physical: Building, ducts, equipment, fibre, etc

Logical: 1:1 fibre, SDH SNCP, Ethernet LAG, users/MSAN, users/call server, 8021ag, FRR, Graceful Restart, Link colouring for MPLS TE paths, Liberal Labelretention
Recover at the lowest level possible
Maintain service availability across 21CN
21CN: Looking at some possible next
steps beyond PSTN and Broadband

Enhancing the Ethernet backhaul network to support legacy connection-oriented services

Multicast

Pseudo Wires supporting end customer point to
point services across the MPLS core

VPLS within the converged core to support end
customer IP/Ethernet VPN services

Integration with BT’s global MPLS network for
delivery of next generation services
In conclusion
21CN will transform the way society communicates and businesses is conducted
21CN will use Ethernet for aggregation, backhaul and end to end service delivery IP/MPLS will remain in the core
21CN will be carrier grade, secure and industrialised
