Customer migration is underway

• The first customer migrations began on 28th
  November 06 in Wick, near Cardiff.
• The principle of building up gradually, ensuring
  infrastructure and full testing at each stage, is
  supported by industry.
• Customers in Cardiff, Bridgend and the Pontypridd
  area will be the next to have their services
  transferred.
• By the end of 2007, around 350,000 lines in south
  Wales are expected to have been migrated to the
  new infrastructure.
• Migration will be underway in all regions of the
  UK during 2008.
• By the end of the decade 21CN migration will be
  substantially complete.
• Customer experience is key to success.

  Verification and Validation (IVVT)
• 600,000 tests (100,000) since November 2006.
• 9,500 trouble reports cleared.
• Test labs at Adastral and Swansea (BT) and
  Solihull, Guilford and Reading (vendors with BT).
• Test model equivalent to 20 UK inner core
  capacity.
• Customer Premise Equipment (CPE)
• Hundreds of CPE tested in the LAB and Swansea CP
  test facility.
• Industry invited to offer CPE for testing.
• Results published in open forum to industry via

TE trials and testing, three phased approach

• Proving the manual/automated methods for
  preparing the frame for TE.
• Producing quality procedures.
• Testing the synthetics used in modelling
  resources.
• Assessing the impacts on customer service.
• Progressively introducing the testing and
  trialling of Voice, Broadband and ISDN,
  migration methodologies.
• Use of business scenarios / test cases to
  provide end-to-end testing of migration.
