Introduction
• The purpose of this presentation is to explain the process of migration to 21CN:– Testing activities across the programme.
– What happens before, during and after each migration phase.
– Quality gate process and role of the Migration Control Centre (MCC).
– Migration into business as usual.
– Fallback and emergency & critical services.
• The intended audience is:– Communication providers (CPs) and resellers.
3
What’s been done to date?
Consult21 - ensure industry is aware of the 21CN vision and BT’s progress towards it.
Proof of process - consultation, engagement, transparency.
Testing - lab tests.
- test calls.
- CPE compatibility tests.
Pre-migration work – infrastructure, products.
switched-on – the industry-wide, non-commercial campaign to communicate about the process of migration.
….and the migration has started!

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.

The many facets of testing• Proof of Concept
• Vendors testing– Conformance Testing (CT), Multi-Vendor CT (MVCT) and
Network Integration Testing (NIT)
• Operational Support Systems (OSS) testing– Integration Verification & Validation Testing (IVV&T),
end-to-end OSS testing
• Infrastructure/network testing– NIT and First Office Application (FOA)
• Service testing– User & Live Acceptance Testing (UAT/LAT), Service FOA
(SFOA), Consult21 Conformance Testing Working Group, Experience Development Centre (EDC), CP test facility Swansea
• Transfer engineering (TE)
• Test tools and test automation

Lab Testing
• Network Integration Testing (NIT) and 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 Consult21 test database.
• Test management & automation– Central management of all test cases.– Audit trail of test configuration.– Database of test results.– Test planning and statistics on test execution.

Live Trials(Pathfinder / FOA2)
• 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.
