What does our NGN look like?

Core network two 400 Gig fibre rings around the main population

centres. 47 core POPs

800 Gig Supercore fibre network around greater London taking in all

the Telehouses and main carriers

Layer 1 & 2, access network building to 2000 exchanges

Exchange MSANs copper and fibre, supporting Residential,

SOHO and SME services

Hierarchical QoS enabled network hence supporting voice and data

services

Impact of Ethernet

Source: Analysis Research, 2007


11/25

The significance of Ethernet

Has become the established standard for networkinterconnectivity, at work and in the home

A disruptive technology, replacing Frame Relay, ATM, E1,Tokenring etc

Can be delivered cost effectively across

large scale NGNs Not distance dependant and highly scalable

End to end standards based, meaning compatibility

Creates another telecoms inflection point


12/25

Three phases of Carrier Ethernet

E-LAN, E-Line, E-Tree services

P2P, P2MP, MP2MP Metro and national Ethernet Layer 2

Access circuits to MPLS

10/100/1000Mbps fibre access, with resilience options

Incremental, flexible service bandwidths/internet over Ethernet option

Aim to be MEF 9 and 14 compliant

Standard

Phase 1

EFM/NGA

Ethernet over

Phase 3

Enhanced

Ethernet

Phase 2

3Mbps-40Mbps service bandwidths over copper

To be included in Ethernet and MPLS services

Option for a lower-cost alternative / different SLA

EOAM 802.1ah - end to end QoS management and reporting

Remote diagnostics capability, enhanced alarm functionality resulting inbetter SLA, reduced downtime, greater visibility of service performance

Bandwidth profiling

Burstable bandwidth option

QoS enabled network

QoS is the differentiator on NGN service delivery.

Network supports Hierarchical QoS

in the core, edge and access

QoS Protocols - MPLS, COS, DiffServ

Precision Time Protocols. IEEE 1588v2

Layer 2 Ethernet OAM, ITU 1731

Layer 3 IPSLA


15/25

Opals SIP development

Our NGN already carries 1.5Billion minutes of VoIP trafficmonth

So where are the network based SIP products?

Connectivity is key in the SIP business

Functionality around In/ Outbound

Centrex- Featureline services IVR services

Number portability

17/25

Managing TDM to NGN migration Leave the choice to the customer.

Our view is we should accept voice traffic into the NGN either asTDM or IP. For both PSTN and ISDN.

Customers migrating to IP PBX may send traffic direct as IP over

DSL or Ethernet.

Customers retaining TDM PBX may send traffic to the NGN overEthernet using Circuit Emulation.

Traffic is carried into the core of the NGN and broken out into

conventional TDM trunk exchanges. This avoids building out TDM/SDH network out to exchanges.


18/25

No 1 in Copper Assurance

Investment of over 5M on copper loop testingOpenreach accept our fault data

Proactive fault management

Fastest average speeds over copper in the UK

Dynamic line management DLM optimises copper line

speeds

Important in EFM deployment.

Our vision

What does our NGN offer our partners?

Separate service from conveyance

Allowing Partners more space to add value

Moving to access based charging

Unify B2B connectivity towards Ethernet.

Roadmap of migration from legacy to NGN operation Network SIP product set in development.

Better transparency of assurance
