Slide 10 Not all NGNs are created equal  ADSL service quality is a function of distance from customer premises to the network.  Ethernet fibre costs are a function of distance from customer premises to the network.  The success of TalkTalk means that we have: A deeply built access network - 1,695 exchanges High capacity core and transit network to the edge – with massive unused capacity It’s a scale game – why?

11. It’s all about scale… Opal Network Currently has 1750 NGN enabled Exchanges  This is 3 times as many as BT  This is twice as many as C&W  The Network currently carries 1.5 Billion minutes of VOIP traffic per month.  There are 4 Million data customers generating 150 Giga bits per second of public internet IP traffic This document is uncontrolled if printed or saved to a non-authorised site.

Slide 14 Other national NGNs BT 21CN  Very good for people in South Wales  BT has to run 16 parallel legacy networks due to the complexity and cost of migration to 21CN – a sub-optimal outcome in terms of efficiency and multiple-service delivery  Long way behind original schedule C&W  Lack the scale to justify density of POPs, 802 vs Opal’s 1750* *www.samknows.com
