• Fibre to the Cabinet (FTTC)
– January 2009; Technical trial begins in Foxhall, Ipswich
– July 2009: Operational pilot begins in Muswell Hill, London & Whitchurch, Cardiff
– Up to 30,000 premises passed
• Accelerated market deployment of FTTC March 2010
– Up to 1m premises passed
– Further locations to be announced in the summer 2009
• Early market deployment of FTTC early 2010 – Up to 500,000 premises passed, including
urban and rural locations
• Opportunity to work with RDA’s that have obtained EU funding

We are investing £1.5bn to
rollout fibre to 10m homes
and businesses, some
40% of the UK, by 2012

Product - why Ethernet?
Established and very competitive equipment market
Common interface across many different physical media (e.g. PONs, Pt-Pt, xDSL copper, Wi-Fi, …)
Includes Ethernet OAM functions which allows:
- Clear demarcation between downstream & upstream providers
- Testing & diagnostics can be performed by downstream & upstream providers independently (key for consistent & good customer service)
Allows ‘downstream’ providers to innovate in IP services unhindered by details of ‘upstream’ technology
Multi-service:
- E.g. VoIP, Video, Broadband, IP VPNs on the same physical interface

GEA-FTTC selects lines to deliver assured 15Mb/s downstream DSL line rate.
• FTTP platform uses dynamic bandwidth allocation to offer peak rates above the committed rate. There is the opportunity for further product bandwidth
enhancements e.g. the current generation of ONTs is capable of supporting a 1Gbit/s peak rate service.
Voice over NGA
• VoNGA provides CPs with a WLR like product and consumption model (Wholesale Calls, CPS, IA).
• Ensures continuity as close as possible to existing CP interfaces. • Enables USO and PATS commitments to be met over NGA (FTTP). • VoNGA is provided as an equivalent product to all CPs.
• Internal Technical Trials Q2/Q3 2010/11. • CP Trial engagement post Nov 2010.
Following consultation, also considering CP controlled ATA –
• CPs’ own call server • CPs’ own product set
