Confirmation of the 2Mbit/s & above TDM strategy
HOW >Two distinct bandwidth areas –
Sub 2Mbit/s2Mbit/s & above Based on consultation with Industry
Use of formal feasibility study to assessShared with industry
WHAT >Deliver the same product functionality as 20CContinue to offer Customer Experience as is currently provided on 20CEnsure changes are in collaboration with Customers with minimal service impactIntention is to retain existing systems for ordering, billing, faults etcUpgrade obsolete 20C infrastructure with 21CN Native TDM componentsMinimize disruption as a result of infrastructure upgrades
Native TDM Services
5
Feasibility & approach for sub 2M/bits TDM circuits
Feasibility has started
Interim Update March 2009
Expected completion June 2009
Covers Analogue & Digital Services, based on the requirements fed in from all
interested industry bodies
Specific focus to maintain comparable E2E performance as existing services
6
Feasibility results for 2M/bits & above TDM circuits
A phased approach allowing withdrawal of legacy infrastructure & systems with
minimum customer disruption and over time replacing obsolete components with 21CN Native TDM compliant components and systems supporting
existing products
Continue with the majority of our 20C PPC portfolioContinue to use native SDH technology (no emulation).Retain existing Access and NTEInfrastructure upgrade activity will take place as business as usual
The PPC product will retain its existing framework - i.e. a Point of Handover (POH), a 3rd Party end and a Circuit between these two points
PPC services (including PPC V1 and PPC V2) will continue to be delivered as per the current product definition.

21CNNGN
• 21CN transmission is same technology as 20CN SDH & WDM – just more up to date equipment
• 21CN transmission is a bearer for 21CN NGN• 20CN transmission is separate – not currently connected to 21CN• All TDM is currently routed over 20CN
Existing transmission & TDM services
TECHNOLOGY CHANGEOUT STRATEGY

21CNNGN
• Need to begin to move customer sites onto 21CN to close 20CN infrastructure as it becomes obsolete
• Customers with multiple sites will have some delivered on 20CN infrastructure and some on 21CN infrastructure during the changeover
• This will result in mixed 20CN & 21CN infrastructureUPGRADE WILL BE PLANNED TO MINIMIZE DISRUPTION
Upgrade of obsolete 20CN to 21CN infrastructure

TDM STRATEGY – SUMMARY Evolution not Revolution
• Industry consultation and customer feedback has shaped the decision process
• Two separate areas involved - Below 2Mbit/s and above 2Mbit/s
• Sub 2Mbit/s Feasibility continues
• 2Mbit/s + PPCs remain on the BTW portfolio until well into the next decade
• Native SDH Technology
• Existing PPC functionality will be supported
• Existing NTE will continue to be used and replaced only when obsolete
• 21CN components in solution design for 2009 deployment
• Transformation will be & infrastructure upgrades will be phased
• Engagement remains pro-active through Consult 21 and ongoing

GLOSARY OF KEY TERMS
Native TDM Non emulated transmission providing contention free point to point bandwidth
Legacy Pre 21CN equipment maintained in the network
Bearer A higher bandwidth circuit that can carry a lower bandwidth circuit
