Learning from Pathfinder so far

• Key findings

- Proved the slow start approach taken is the correct one

- Tested the technology, processes and supporting tools with CPs

- Fault numbers continue to run at a low level, at or below numbers for 20C

• Niche CPE problems now understood and fixes planned

• No significant issues with Caller Display, burglar alarms or ATMs

• No recent significant platform issues, good call quality & good network performance

• CP confidence built

Pathfinder – the next phase

• Moving into “Pathfinder Volume POTS”

• Voice migrations only, not ISDN2/30

• January 2010 through to July 2010 • Increasing the South Wales footprint

• 7 DLEs to be migrated – Cardiff G, L, E, F, Bridgend, Cardiff B & Pontypridd

• Will complete the migration of up to 260K lines

• No change to architecture for Pathfinder Volume POTS - Ericsson based call server

• Gradual migration of groomed or regressed lines will take place

• July 2009 – September 2009 - Call Server and MSAN upgrades in Pathfinder area – providing further functionality and increased industrialisation
